Yes, Organic-Lock™ blended aggregate remains permeable to water after installation. This reduces runoff volume and allows some water back into the root zone for trees and eventually to the groundwater table. The permeability rate will change over the course of a rainfall event given the nature of the Organic-Lock™to swell with water and hold the aggregate in place. The highest rate of water infiltration will occur at the beginning of a rainfall event when the blended aggregate is dry – as the Organic-Lock™ naturally swells on contact with water to hold the aggregate in place, the rate of water permeability slows.
Check out this video for a detailed explanation of Organic-Lock’s water permeability.
It is important to recognize that the optimal installation of the Organic-Lock™ blended aggregate incorporates crowns and swales to shed the water off of the surface and prevent sitting water as much as possible.
As with any permeable surface, the level of permeability can also change over time as the surface becomes contaminated by the surrounding environment (i.e. soil, silt, debris etc.).
The porosity of the specific aggregate blended with the Organic-Lock™, as well as the level of compaction, can have a significant impact on permeability.
Yes, vehicular traffic is acceptable, and the Organic-Lock™ stabilized material should be installed at a minimum depth of 4 inches in this type of application. It is most important that an appropriate base profile is installed to support heavier traffic.
Although the material has a monolithic appearance upon final compaction, natural weathering and traffic will expose some loose particles on the surface to give it a more natural look and feel.
When installed with a proper base, Organic-Lock™ blended aggregates can achieve the load-bearing performance required for vehicular traffic while maintaining the aesthetic features and water permeability of a natural aggregate.
Yes, an Organic-Lock™ blended aggregate surface can support vehicular traffic. It is most important that the base is properly constructed to support heavier traffic (8-12 inches of compacted ¾” crushed stone) and the Organic-Lock™ material is to be installed at a depth of 4 to 6 inches, compacted in lifts of 2 to 3 inches at a time.
NOTE: Please see the following guidelines for more information about each type of application:
The maximum slope that is acceptable for an Organic-Lock™ stabilized aggregate application is 20%. For slopes that are 10% or greater, it is recommended to install runoff “diverters”, which are materials such as railroad ties (or equivalent) embedded in the pathway at a 45-degree angle to prevent water gaining momentum which can accelerate washout damage. Proper watershed management is best achieved by installing a “crown” or “cross-slope” to divert rainfall runoff to flow off the side of the application to prevent washout damage.
Yes, it is acceptable to install the material with a grid product, but the installation process must be modified. Instead of pre-hydrating the material, fill the grid cells with dry blended material and surface wet the material with a light water spay. Then install a 2-inch compacted layer of pre-hydrated material on top of the filled grid cells and proceed with installation as per our regular instructions.
No, the aggregate mixed with Organic-Lock™does not have to be a granite material. Generally, limestone and decomposed granites tend to perform the most reliably, however other materials can also work as long as the particle size distribution fits our Optimal Gradation Specifications (click here) The surface texture and angularity of the crushed stone particles are also important factors.
No, pea gravel or beach pebbles lack the fine particles required for the Organic-Lock™ to effectively bond with the aggregate. These materials are also very much “rounded” which make them unable to create an “interlocking” matrix within the aggregate itself. Crushed aggregate that have angular or sub-angular particles are optimal for proper interlocking within the aggregate.
In extreme rain conditions, the material will resist washout very effectively with a proper watershed management plan in place. Should any washout damage occur over time, the material is easily repairable.
At the present time, there has not been significant field research on the performance of Organic-Lock™ in relatively wet/damp environments but as long as a proper watershed management plan is in place, we do not expect moisture in the form of humidity to be detrimental to the Organic-Lock’s performance.
The self-healing feature of the Organic-Lock™ makes it ideal to install in regions with extreme weather conditions. Extreme heat has not been shown to degrade Organic-Lock™ at any significant degree. Extreme cold may cause the ground to expand but the Organic-Lock™ will settle and reset upon thawing.
Although the active bonding agent is a similar type of plant material, Organic-Lock™ is a patented blend that includes a renewable plant resource combined with specialty designed additives that both increase longevity and enhances bonding strength, leading to superior stability compared to the Stabilizer product. See the test report here [insert link to performance test report – *Coming soon]
The pH of Organic-Lock™ is approximately 11, providing a level of weed deterrence and also increasing the longevity of the plant material in the binder. This high pH slows down the microbial degradation (i.e. increases longevity), and it also makes it an unfavorable growing medium for new seeds (i.e. weeds) to germinate.
It is completely normal for loose particles to become exposed on the surface of an Organic-Lock™ application. This is part of what provides the natural aesthetic of aggregate surfaces that is so sought-after today
While Organic-Lock™ blended aggregate has the strength and load-bearing capability of concrete or asphalt, it looks and feels more like a crushed stone surface without a binder. Our product is not designed to be a monolithic surface like asphalt or concrete, but rather a flexible natural paving surface that can settle with the surrounding earth. The natural flexibility of the Organic-Lock™ will allow the material to consolidate, which will actually increase the overall strength and integrity of the stabilized surface over time.
When there is a thin layer on the surface that appears to be like a “skin”, separating from the rest of the material and cracking, it suggests that the material was either pre-blended with:
Depending on the severity of the situation, the material can either be:
In our experience, washout is often the result of a weakness in the watershed management plan. It would be best to pinpoint the source of excessive water and divert it accordingly. Examples would be dripping water from a man-made surface above or a heavy water concentration coming from an impermeable surface above the damaged area.
The odor issue is related to moisture that doesn’t have a chance to release. Over-watering the material before installation is often the cause. The over-watered material that is installed and compacted on a hot or sunny day will form a crust on the surface which prevents the excess moisture from evaporating, which is the fastest means for the material to dry. The water inside the material essentially bakes the binder to exacerbate biodegradation, creating a gas which releases in the form of an odor.
The best way to avoid this situation is to prevent oversaturated material from forming a crust on its surface (whether in an installed setting or in a pile). When the material is oversaturated and does create the gas causing the odor, time will eventually allow that excess water to percolate down and evaporate out, with the odor remaining until that build-up of moisture has been released.
Organic-Lock™is designed to be blended with Crushed Aggregate Screenings, as it gains its strength from a well-graded profile of angular to sub-angular particles. Although the Organic-Lock™can stabilize a native soil, it should not be used in areas where you will be planting any type of ground cover since the elevated pH of our product will inhibit small plant growth.
In situations where the native soil is intended to be used for foot traffic or equivalent, it is possible to integrate Organic-Lock™for this purpose.
In situations where it is not possible to introduce a foreign aggregate material, whether due to ease of access, inability to disrupt existing rooting systems, or simply just a lack of access to optimal crushed aggregate, it is possible to blend Organic-Lock™into existing in-situ material, accepting that the performance will not achieve the optimal levels and it will vary from site condition to site condition and from in-situ material to in-situ material.
The recommended process is to create a sample plot area with different concentrations of Organic-Lock™blended into the top 3 inches of the existing material to test and achieve the performance you are looking for. Create a sample area that best represents your overall site conditions, and thoroughly blend the Organic-Lock™powder into the top 3 inches using a rototiller or equivalent. Rates of Organic-Lock™can vary depending on the intended performance you would like to achieve. A higher concentration will result in a firmer surface, where a lower concentration will allow greater permeability but will result in a less firm surface layer. Most important is to blend it in to achieve a full and homogeneous mixture.
Highest/Most firm: 50 lbs = 100 square feet (at 3 inches)
Lowest/Least firm: 25 lbs = 100 square feet (at 3 inches)
Once the Organic-Lock™is blended into this surface layer material, you need to add water to activate the bond. Add water slowly to bring the moisture content up to approximately 10%. This is done by adding the water and thoroughly blending the material using the same process you blended the Organic-Lock™binder into it. Do this thorough blending until you achieve the proper moisture percentage.
To understand when you have hit the optimal moisture level, you’ll want to use a snowball test by picking up the material and creating a snowball. You want to achieve the consistency that just barely allows you to hold the snowball form without it crumbling. You don’t want to over-water where it easily holds its form and creates a wet sheen on the surface (this is a sign of over-watering) …you’re looking for the level just before this.
Once the Organic-Lock™is blended in, and the water is subsequently added and properly and thoroughly blended in, you can roll the surface using a weighted rolling device. A minimum 500lb-2000 lb roller is ideal.
Leave your sample plot area for as long as you need to analyze the performance to ensure it meets your expectations. Curing times will depend on many factors including, but not limited to, climate conditions, canopy cover, base drainage, and temperature.
It is recommended to use a Structural Soil blend when installing a surface material intended for traffic up to the trunk of the tree.
Installing Structural Soil is recommended below the root base and out to the radius of the root ball (even extending up to 12′ for more sensitive trees).
Install the Structural Soil in lieu of the base material (at the same depth) and then proceed with the Organic-Lock™blended aggregate mix over the surface of the compacted structural soil.
Options (lowest to highest rates of permeability):
Be aware that by not using a proper base material up to the trunk of the tree that this area may not firm up to the same level as the other areas but there also shouldn’t be much traffic right by the base of the tree anyway.
Once we learn more details about the potential project or dealership, we would be glad to send you a trial-sized bag of Organic-Lock™ at no charge. This trial-sized bag will contain sufficient Organic-Lock™to construct a 4’x4′ test plot when blended with your own aggregate.
Organic-Lock™ can be purchased from your local licensed distributor. If there is not a licensed distributor in your territory, the Organic-Lock™ is to be purchased directly from Envirobond and please be prepared to blend the material yourself.
Organic-Lock™ can be delivered in a VAN, on a FLATBED or in a RAIL/SHIP CONTAINER.
Flatbed (20 pallets) – more expensive but easy to unload (from all sides)
Van (20 pallets) – can only unload from the back (if no loading dock, must be unloaded by hand) – dealer has the option of dragging pallets to back for unloading, using only their own resources.
Rail Container (20 pallets – pallet dimensions are the limit here) – 108” high “Super Container” so forklift can drive in/out.
Absolutely NO double stacking of pallets.
*driver assistance is considered an additional charge by all carriers.
The maximum number of Organic-Lock™ pallets that fit on a full truckload is 20 pallets (40,000 lbs).
No, freight is an additional charge that is quoted on a per order basis since the order size will play a part in dictating the rate. Please confirm an expected order quantity and we will source a freight rate for you within the next 1-2 days.
NOTE: All freight rate requests need to be requested at the time the order is placed and you must specify the truck type required and delivery address (please provide the receiver’s name & phone number).
Organic-Lock™ is available is two package sizes:
It is ideal to store Organic-Lock™ indoors and properly covered to prevent contamination.
Yes, Organic-Lock™ blended aggregate can be stockpiled, but it should be installed within 24 hours of blending. The natural moisture in the aggregate can compromise the Organic-Lock™mixed within when it is not fully activated in an actual application. If a pile of blended material receives rainfall, the Organic-Lock™ will leach out of the material and therefore compromise the mixture and eventual end product.
If absolutely necessary, Organic-Lock™ blended material can be packaged in bulk bags if the aggregate is 100% dry before blending. If the material is stocked for an extended time period, the finer particles will naturally settle to the bottom of the mixture and it should be remixed on site before pre-hydrating.
As long as the Organic-Lock™ is properly covered and stored in a dry location (free from moisture and humidity), the Organic-Lock™ will remain usable for 1 year.
Make a compacted ball of blended material in your hands or step on a ball of material with your work boot. If the blended material falls apart easily, more water much be added. If there is excess water visible on the surface of the compacted ball, then some dry blended material must be added to the over-hydrated material. If the ball holds together firmly or your boot imprint is free of cracks, the ideal moisture level has been achieved and you can then proceed with installation.
The best way to look at this is to start with a low level of moisture, and systematically add a small (measured) amount of water each time until there is just enough…You’re looking for the following – the spot where there isn’t enough moisture – add slightly more, there’s more but still not enough – add slightly more, there’s even more now and it’s holding together but not creating a firm snowball – add slightly more, there’s just enough moisture now that barely holds a snowball together- STOP! This is the best way to add just the right amount of water without going over.

Generally, limestone, dolomites and decomposed granites tend to perform the most reliably, however other materials can also work when the particle size distribution fits our Optimal Gradation Specifications. As a general rule, an acceptable aggregate will be in the form of a 1/4” minus or 3/8” minus with at least 5% fine particles passing the #200 sieve.
Please note that it is ideal for the daytime temperature to be at least 40 degrees F (5 degrees C) for installation of Organic-Lock™ pathway material. This will allow the material to start drying out to allow the bonds to properly set. It is also recommended not to install frozen chunks of material.
Do not blend in the rain. Do not install in the rain. Rainfall can have an adverse effect on the Organic-Lock™ if it has not yet been installed and compacted as blended material. If it is raining during blending/installing, it is possible that the material will become too hydrated, making it difficult to work with since the Organic-Lock™ could become fully activated and will stick to your equipment.
No, we do not recommend blending new material using this method due to the high risk of contamination and the lower chances of achieving a homogeneous mixture.
They do make a small walk-behind single-drum or double-drum version of a big steam roller that you may be able to find at an equipment rental place. A greens roller has also been used successfully in tight areas. Since neither water filled drum rollers nor hand tamping apply enough weight to compact the aggregate properly you are better off using a vibratory plate compactor if that is your only option. When using a vibratory plate compactor, you will have to be aware that this will make for a poor installation because the vibration will jar loose the aggregate on the upper surface and will never reach optimum compaction. You would then have to go over with a water roller for a smooth final finish.
Wherever this is not suitable or available, the hand tamp can be used as long as enough attention is given to the significance of the compaction weight.
The longevity of the Organic-Lock™ is mostly dictated by the unique environment in which it is installed. Factors such as watershed, climate, precipitation, canopy cover, traffic and installation all influence the longevity. A natural aggregate surface is most prone to potential damage (washouts, displacement, etc.) during the first few years of its lifetime before it becomes additionally compacted and consolidated by foot or vehicular traffic. Organic-Lock™is the most effective during this initial period of potential stress. As the aggregate consolidates with traffic, weathering and overall compaction, the Organic-Lock™takes a back seat and the aggregate takes on the heavy lifting. We’ve seen successful installations lasting well over a decade.
