G3 - Pathway Stabilizer (G3-PS) is a liquid polymer stabilizer recommended for residential pathways, planter beds, and xeriscaping that is applied to crushed stone mixes, such as decomposed granite (DG), limestone, and bluestone that creates an environmentally friendly, natural surface. G3-PS is also commonly used in xeriscape settings where low water usage and low maintenance are critically important. This often includes replacing grass and other ground cover materials with DG stabilized using G3-PS.
G3-PS installs quickly and easily in just a few simple application steps. Preparation is similar to installing a traditional crushed stone walkway. G3-PS binds the crushed rock and fine particles in the aggregate mixture, creating a solid and durable surface which helps alleviate common natural surfacing problems such as weeds, insects, erosion, and tracking of loose materials into the home.
G3-PS is easy enough for a DIY individual to install and durable enough to exceed the demands of a landscape or hardscape contractor. It can be used for pathways, garden planter beds, or any place you want a natural look without the maintenance while maintaining the character and appeal of a natural surface. G3-PS is EPA-compliant, VOC-free, and completely safe for use around people, animals, fish and wildlife. e
G3 - Pathway Stabilizer is recommended for use on residential pathways, planter beds, and xeriscaping projects where there is light to moderate foot traffic. G3 - Commercial Surface is recommended for use on commercial or residential walkways, patios, common areas, and xeriscaping where there will be a higher volume of foot traffic, especially on areas where patio furniture or outdoor living accessories will be frequently used. Neither are recommended for use in a vehicular or heavy equipment application under any circumstances. G3 - Commercial Surface contains an extra strength polymer formulation by comparison to its counterpart G3-PS, and is applied at a different application rate. Please consult the bottle label and product installation guides for more detailed information on each.
The goal of a natural pathway is to enhance the landscaped area with a foot traffic surface that appears as though it occurred naturally or at the very least it was built with some natural materials. A natural pathway is visually pleasing, usually much cooler on the surface, and a cost effective way to landscape.
There are many variables to consider here, but most importantly, the aggregate used. Some people prefer a smoother texture and others prefer a rougher texture. The texture is directly affected by compaction and the gradation of the material used. G3-PS will not change the aesthetic of the surface material, nor is it meant to. To get an idea of what the finished product will look like, perform a small mock-up section with the material selected. At times, different textures can be achieved with techniques and tools not listed in the basic installation guide. For more detailed questions, please contact the Technical Support department.
No, and it’s important remember the goals of installing a natural pathway. G3-PS adds stability by way of cross-linking polymer bonds throughout the surface material layer. It also greatly reduces tracking of loose materials, which makes for a neat and clean pathway. Concrete is an engineered combination of materials and a more costly and labor intensive process by comparison, despite its durability and longevity.
Yes, this is a critical factor. The coverage rates for G3-PS come from extensive testing, research, and development over the last decade. Under applying G3-PS will not only leave you with an unsatisfactory pathway, it can lead to other aesthetic issues. Over applying G3-PS is also not recommended as it can lead to the washing out of fines and longer cure times.
It’s simple, by evaporation of the water component. G3-PS is an industrial strength, water-based, liquid polymer formulation that is environmentally safe. Water acts as a carrier for the polymer to penetrate the surface material. Once the water component has completely evaporated (or dried), the polymer is able to cure and provide cross-linking strength.
It would technically be labeled as low maintenance. In fact, most pathway projects need very little maintenance inside of 1-2 years. A maintenance topcoat of G3-PS liquid combined with any needed divot repairs is easy, and much less costly than maintaining or repairing concrete or hardscape surfaces such as pavers or flagstone.
G5 was developed as an industrial trail and road building polymer, that has since revolutionized vehicular and heavy equipment surfacing. It is a cold mix polymer that blends with crushed aggregate mixes, native soils, and recycled asphalt to create and incredibly durable surface often stronger than concrete. G5 is recommended for professional installation on roads, trails, parking areas, golf cart paths, and anywhere ADA compliant natural surfacing is needed. It requires knowledge, experience, and specialty equipment, similar to that of a concrete installation. It is not available in the retail market, and is exclusively manufactured and distributed by TechniSoil Industrial, LLC (sister company to TechniSoil Global, Inc.).
Both G3 liquid polymer stabilizer products have been tested for abrasion resistance, a key criteria for ADA compliancy, and passed respectively. However, it is important to note that inclement weather and groundwater or drainage issues can pose issues for ADA compliant surface rigidity of many polymer stabilized aggregate mixes. For projects that have a ADA compliancy requirement, it is strongly recommended to use industry proven G5 liquid stabilizer. Although G5 is not available in the retail market, more information about G5 availability and installation specifications is available directly from TechniSoil Industrial, LLC.-
As the name implies, pathways. These would be residential, foot traffic pathways that connect areas around the home. If considering a high foot traffic area, we recommend to use our extra strength product called G3 - Commercial Surface.
No, but we do offer a product specifically designed for that application, NanoPave JSS.
No, but it’s important to remember that the reason has more to do with the surface material being used. Vehicles and equipment place tremendous stress on a surface. DG and crushed stone mixes inherently soak in water which means a rain event can soften materials. Cars or trucks will create ruts in this environment which would damage the aesthetic.-
Shovel, steel-toothed rake, edging material, wheelbarrow, watering can w/ shower head, pressurized sprayer (often preferred for 2nd coat application), a vibratory plate compactor, hand tamper, gloves, plastic to cover surrounding areas from accidental spills. Additional tools may be required for demolition, edge restraints, or other special circumstances.-
3/8” minus or 1/2” minus aggregates are recommended for use with TechniSoil G3 - Pathway Stabilizer. Common aggregates are DG, limestone and shale. These will have a consistent blend of crushed, angular aggregates down to stone dust. Screened, washed and sandy aggregates are not suitable.
The TechniSoil G3 product line is not recommended for use with pea gravel, glass or screened materials. A decomposed granite (DG) or crushed stone mix with a gradation of 3/8" minus (crushed stone down to fines) is required. In order for the product to perform well there needs to be a blend of aggregate chips and stone dust/fines.
By performing a simple compaction test. A suitable aggregate must be able to stand up on its own first, to then be improved with the cross-linking polymer bond of G3-PS. Spread a small amount of the aggregate on the ground and compact by hand, then step on the aggregate with a toe or heel and turn a few times. If the material immediately falls apart, the aggregate is not a good pathway material. If the material holds together fairly well, then it will be enhanced significantly with G3-PS. A common material that does not work well is sand or sand-based mixes. While sand compacts well in a subbase for some hardscape uses, it breaks down easily when walked on regularly.-
Edge restraints are very beneficial, and recommended whenever possible. Plastic and aluminum edging are the most cost-effective options and will help secure and frame the treated surface. Concrete, stone and pavers are also good edging materials. Edging will greatly increase the quality of your treated surface.
When installing the loose 1.5 - 2” layer of surface material, the top of the aggregate should be ½ - ¾” above any edging. Gently slope or crown the surface material and avoid low spots.-
Subgrade is the area of native soil below the surface material layer and the subbase. This is usually the grade left after excavation when starting a project. Subbase is the layer directly below the surface material layer, that is made of up compacted, crushed base rock. The subbase is a critical part of any pathway or patio project.
NO. This is a very common misconception about natural pathway construction. Even the best weed fabrics slow the transfer of moisture to the soil below. This creates a dam effect below a natural pathway that can cause it to stay in a wet or soggy state much longer than it should. A natural pathway relies on drainage and runoff primarily, and then permeability secondarily to stay intact. In areas where tough weeds are an issue, it is recommended to excavate deeper initially and install a thicker subbase layer. Weeds are not likely to grow through the subbase layer, and surface layers weeds (if any) are superficial meaning they got their start from above not below.
In most instances, yes. Unless there is room to build up 4 - 6” from the existing grade, excavation is required to accommodate the subbase material and the G3-PS treated surface layer.
Yes, it is highly recommended to use a structural base-rock below the G3-PS treated surface. A base-rock will provide structural stability and protects the top surface from destabilizing with expansion contraction and movement of the soil. In California it is referred to as Class II base-rock (¾” minus). It may have different names in different parts of the country, but structural base rock is usually available through landscape and material suppliers nationwide.
In most cases, a 2 - 4” layer of ¾” minus base-rock will create a stable foundation and assure a solid footing for the G3-PS treated crushed stone surface. An inadequate structural base can create durability issues. It is recommended to lightly water, then compact the base course with 3-4 passes with a vibratory plate compactor.-
1.5 - 2” over the compacted sub-base is what are application rates are designed to stabilize. Thinner layers will not be as durable and thicker layers cannot be fully stabilized.
The first of two applications must be poured in before compaction to allow the polymer to penetrate into the surface layer material. This is precisely where the cross-linking strength and stability traits come from after compaction. Applying G3 after compaction (such as topcoats or future maintenance coats), will tighten up and seal the surface helping to prevent dust and loose materials, but will not be able to permeate the surface layer to provide any further significant stability. Please refer to the product install guides for more detailed information.
A G3 - Pathway Stabilizer stabilized surface layer will technically still be permeable, as most crushed stone mixes and DG will inherently soak in water. However, for optimal performance, it is recommended to follow slope and drainage guidelines similar to concrete and hardscape installations. Meaning, water should be allowed to run off and not pool over the surface layer.
There are two reasons cracks can appear in a crushed stone or DG surface treated with G3-PS after compaction; 1) G3-PS was applied when the air/surface temperature was to hot, or; 2) The G3-PS treated surface was compacted when the moisture content was too high. If the temperature is too high the moisture will evaporate quickly, which can create cracks. More commonly, however, cracks can occur if the surface is compacted when the treated material is too wet causing it to smear.
To avoid this it is recommended to test the treated material before compaction. A simple hand compaction test is all that is needed normally, or the use of a soil moisture meter (7-9% is optimal). Test four or more areas by picking up some of the treated material and making a ball. If the material holds together like a snowball or sandcastle sand, this is a sign that the surface is suitable for compaction. If the treated material seems muddy, this is a sign there is too much moisture and another test can be performed 15-20 minutes later.
G3 - Pathway Stabilizer covers up to 75 ft2 per 5-gallon bottle via 2 applications; a 20 ft2/gallon pour-in application before compaction; and a 50 ft2/gallon topcoat application after compaction.
It is strongly recommended to adhere to installation and application guidelines. Under-applying G3 - Pathway Stabilizer will result in reduced cross-linking strength and surface stabilization, which are two of the primary benefits to using the product in the first place. Leftover liquid can be stored for maintenance applications as needed.
Lightly misting the surface layer material with water can be helpful in some situations, most notably, when the decomposed granite (DG) is very dry. It’s also helpful when installing on hot days (above 85o F). Misting the surface material helps break the surface tension which allows deeper and more thorough penetration of the G3 liquid polymer. An easy test to determine if the DG is dry is to grab a handful of material and then pour it slowly to the ground from 1’ - 3’ away. If the material does not stick together at all and creates a dust plume, it’s likely dry and could benefit from a mist coat of water. Most materials hold moisture during storage though, even in warmer weather so be sure to test multiple areas. To assure the best results after prewatering, it is recommended to lightly rake the top 1" of DG so the stone dust and aggregate chips are consistent. Over-watering can cause the stone dust and finer particles to be inconsistent.
No, it is only recommended if the surface material (usually decomposed granite) is verydry or if installation temperatures are warm to hot. Most materials retain moisture during storage, even in warm temperatures, and will not need to be prewatered before the G3PS pourin application. It’s important to avoid oversaturating the surface material. This can cause other issues such as washing down fines that are critical to compaction, and delaying or affecting the compaction stage due to soggy material.
For the initial pour-in application coat of 20 ft2/gallon, a garden watering can with a shower head is strongly recommended and is the easiest and most effective tool. The initial coat is intended to saturate the area, absorb, and disperse throughout the surface layer of crushed stone. Often times a pressurized sprayer is preferred when applying top coat application (after the pour-in application and after compaction), since there will be more control over the application of the G3-PS liquid. It is recommended to mark off 20 square foot sections for the pour-in application to assure the proper amount of liquid is being applied. The amount of Pathway Stabilizer liquid is critically important to a successful installation.
After the initial pour-in coat of G3 - Pathway Stabilizer has cured for 6-24 hours (after compaction), the topcoat application of can be applied.
It is recommended to apply the top coat (2nd coat) of G3 - Pathway Stabilizer no sooner than 6 hours after compaction. For best results we recommend to wait until the following day to apply the top coat. This allows for the 1st coat to begin curing, so the topcoat application can filter to the areas that need it the most. If the topcoat is applied too soon it can affect the compaction and aesthetics of the surface by washing out fines or stone dust particles.
Apply G3 - Pathway Stabilizer at a rate of 50 ft2/gallon.
Either a garden watering can with a shower head or pressurized pump sprayer can be used. We have a pressurized sprayer is most commonly used for the topcoat application since there is more control over the coverage.
After the 2nd coat of G3 - Pathway Stabilizer is applied the curing process begins. In optimal conditions the surface will cure within 24 - 72 hours. Since humidity, temperature and atmospheric conditions can fluctuate it can often take longer than 72 hours to fully cure. Once all water has evaporated from the crushed stone and the treated surface is dry and hard to the touch, it is cured. If the material is still wet or soft, allow to dry and completely cure before using the surface.-
YES! Compaction is (aside from the application of our product) the most crucial element to ensure proper installation of your G3 - Pathway Stabilizer surface. Optimal compaction will create the a durable, stable, and longer lasting surface. It is recommended to achieve 95% compaction of both the subbase layer and the surface layer using a vibratory plate compactor. This level of compaction cannot be achieved with a hand tamp or water roller.
A vibratory plate compactor is the best tool available to attain optimal compaction. It is suitable to use a hand tamper in areas that cannot be reached by the plate compactor, such as tight corners, but should not be looked upon as a substitute. For larger surface areas (2000 ft2 and larger) a double drum mechanical roller can be used. A vibratory plate compactor will push the heavier aggregates below surface for structural support and will bring the finer grained material to the surface for a consistent aesthetic.
In optimal weather conditions between 65 - 85º F, the surface should be suitable for compaction 45 - 90 minutes after application of G3-PS. In overcast, shaded and/or cooler conditions the time before compaction could be extended to over 90 minutes. If the material is too saturated it will not fully compact and can create aesthetic blemishes and result in inadequate compaction.
No. After the initial 3 - 4 pass compaction run, the vibratory plate compactor should not be used again. Once the initial compaction run has been completed, the surface layer is in its curing phase. Any mechanized compaction performed after this point can cause significant damage to the surface, by actually undoing the work that was already in place. If there are any surfaces blemishes that need touching up after the compaction run, it is recommended to carefully use a hand tamp and trowel to smooth or blend the repair areas.
A moisture meter is helpful in determining the best time to compact. Simply test several areas of the aggregate for a moisture content between 7 - 9%, which is optimal for proper compaction. Another method is to test several areas by hand. Collect a handful of the treated material and try to make a ball. If it holds together like a snowball with the consistency of oatmeal, but does not leave gloves wet or muddy, it is likely ready for compaction. If the material is muddy wait an additional 15-20 minutes and re-test.
During compaction, if the surface looks smeared, heavily ridges or sticks to the bottom of the compactor, this is a sign that the treated material is still too wet for compaction. Use a landscape rake to loosen the compacted area and wait an additional 15-20 minutes then re-test for moisture suitability.
When the surface is ready for compaction make 3-4 passes with the plate compactor. Make any cosmetic fixes or structural repairs (low spots, uneven surfaces, etc) after the 1st or 2nd pass.-
By starting from scratch whenever possible, or when certain elements of an existing pathway are unknown. When planning a project from the beginning, all installation variables can be taken into consideration and recommended construction methods can be followed. Skipping steps or relying on components from an older installation can often times lead to problems or undesired results.-
In most instances the answer is yes, but there are several aspects that need to be addressed beforehand. Is the existing crushed stone suitable? Is there an appropriate base material? Is there proper drainage? Since each project has its own set of variables and in order to assure optimal results for existing crushed stone applications it is recommended to directly contact our Technical Support department at 877-356-2250.-
When finished applying G3 - Pathway Stabilizer, simply rinse off your tools with water. For pressurized sprayers it is recommended to rinse out the lines by spraying approximately 16-32 ounces of water through the system. If there are any clogs in the watering can spout or pressurized sprayer tip use a soft bristle brush and water to remove. It is recommended to clean equipment immediately after use.-
On average, a maintenance coat will need to be applied every 12-24 months, depending primarily on weather conditions and surface usage. We have found there will be occasional maintenance that will be required throughout the life-cycle of the surface to account for loosening of areas due to usage or areas affected by weather.
A G3-PS treated surface is resistant to erosion. Although erosion is not common, any running water from heavy rains can cause minor erosion to occur. If this happens, simply re-apply crushed stone to the eroded area and re-apply G3 - Pathway Stabilizer to the loose material. Use a trowel and hand tamper to finish and compact the material into place. Allow area to dry 24-72 hours.
TechniSoil G3 - Pathway Stabilizer was designed to expand and contract in extreme temperatures, so cracking is normally minimal. Cracks can be caused by numerous factors such as; expansive soils, insufficient base material, compaction when the treated material is over-saturated, rain or irrigation before the surface has fully cured, etc. If cracks do occur they can be easily repaired by brushing crushed stone mix into the cracks (use the finer materials or screen the larger rock out for easier application and clean up). Apply the G3-PS to solidify the new material. Allow 24 - 48 hours to dry before usage.
Loose material will occur over time, but doesn't affect the structural integrity in most cases. This is often a sign of an area that get used more and treating these specific areas with a topcoat of 50 ft2/gallon is often sufficient.
Saturated surfaces may soften, but will attain its original firmness after the water evaporates. If there is a proper grade and slope to assure adequate drainage this issue is greatly reduced. This issue usually happens if a finer aggregate is used. A heavier gradation (1/2" minus) aggregate will have more structural stability even when fully saturated. Point load pressure (from chairs or tables) can cause minor blemishes. Using cork or rubber pads on the legs of patio furniture will alleviate this issue. To repair, simply refill the affected area with loose crushed stone, re-apply G3-PS to the area, and lightly compact and smooth to blend with the surface.
For areas that need repair, it is important to first assess the conditions. Often there can be nominal erosion from a heavy rain event or wear and tear. These are usually small areas of less than a square foot in size and are easy to fix. For very small areas simply fill in with loose crushed stone and apply G3-PS (a small spray bottle will work). Use a trowel to compress the material smoothly into place.
To repair larger areas, place the appropriate amount of crushed stone in a 5-gallon bucket and add enough G3 - Pathway Stabilizer to make a consistent mixture of aggregate chips and stone dust (oatmeal consistency). Mix with a dowel or paint stirrer and apply the mixture to the affected area(s). Using a masonry trowel or equivalent, smooth the material to grade. Use a hand tamper to lightly compact into place. 6 - 24 hours after applying the material, spray a topcoat of G3-PS over the repaired area at a rate of 50 ft2/gallon. The repaired area should be cured within 12-36 hours, but will be fully cured when all water has evaporated from the sand/crushed stone and the surface is dry and solid.-
G3 - Pathway Stabilizer is a durable natural pavement solution, but still requires occasional care and maintenance. In average conditions a maintenance coat is recommended every 12 - 24 months. Much like a wood or stone sealant, the maintenance coat works to rejuvenate and strengthen the crushed stone, increasing the life of the surface. The maintenance process is dependent upon 2 factors; the amount of usage and weather conditions. Within the 12 - 24 month timeframe there may be the need for some minor repairs, and it is recommended to repair these areas promptly.-
In either instance G3 - Pathway Stabilizer should be stored in an area that meets two vital conditions; no direct exposure to sunlight and high heat, and in temperatures above 40 degrees to avoid freezing. The shelf-life of G3-PS is 4+ years if stored in optimal conditions. For opened G3-PS containers make sure that the container is airtight and the lid is securely fastened. If the original container has been compromised then it is recommended to transfer the product to a compatible container.-
