Organic-LockPerformance Support

Is Organic-Lock water permeable?

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-Lockto 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-Lockblended 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.

Is vehicular traffic acceptable on Organic-Lockstabilized aggregate?

Yes, vehicular traffic is acceptable, and the Organic-Lockstabilized 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.

Does Organic-Lockstabilized aggregate help achieve Disabilities Act Compliance (ADA, AODA, etc.)?

Yes, projects including Organic-Lockhave been considered ADA Compliant.

NOTE: Our Organic-LockADA Test Report supports this performance feature – ADA Test Report

Will Organic-Lock stabilized aggregate stay hard like concrete?

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-Lockblended aggregates can achieve the load-bearing performance required for vehicular traffic while maintaining the aesthetic features and water permeability of a natural aggregate.

Can the Organic-Lock take vehicle traffic as well?

Yes, an Organic-Lockblended 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-Lockmaterial 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:

Light Vehicular Application
Golf Cart Application
Heavy Vehicular/ Fire Lane Application

What is the maximum slope on which I can install Organic-Lock blended aggregate?

The maximum slope that is acceptable for an Organic-Lockstabilized 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.

Can Organic-Lock stabilized aggregate be installed with a grid product?

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.

Does the aggregate have to be granite, or can it be another type?

No, the aggregate mixed with Organic-Lockdoes 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.

Can Organic-Lock be used with pea gravel, beach pebbles or other decorative stones?

No, pea gravel or beach pebbles lack the fine particles required for the Organic-Lockto 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.

Can Organic-Lock be used in wet/damp, rainy environments?

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-Lockin 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.

Does hot or cold weather affect performance?

The self-healing feature of the Organic-Lockmakes it ideal to install in regions with extreme weather conditions. Extreme heat has not been shown to degrade Organic-Lockat any significant degree. Extreme cold may cause the ground to expand but the Organic-Lockwill settle and reset upon thawing.

Is your product the same as Stabilizer?

Although the active bonding agent is a similar type of plant material, Organic-Lockis 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]

What is the pH of Organic-Lock?

The pH of Organic-Lockis 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.

Why are there so many loose particles on the surface of the Organic-Lock blended aggregate?

It is completely normal for loose particles to become exposed on the surface of an Organic-Lockapplication. This is part of what provides the natural aesthetic of aggregate surfaces that is so sought-after today

While Organic-Lockblended 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-Lockwill allow the material to consolidate, which will actually increase the overall strength and integrity of the stabilized surface over time.

Why is there a “skin” and cracks on the surface of the Organic-Lock pathway?

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:

      1. too much Organic-Lockor
      2. too much water

Depending on the severity of the situation, the material can either be:

      1. carefully excavated, re-blended with additional aggregate and laid back into place OR scarified in place and re-compacted (for the scarification option, you can use a rototiller, a rake, box Gannon, loader bucket or other suitable equipment); or
      2. if too much water was applied, the material should be scarified and spread out to allow it to dry, before it is raked back into place and compacted.
Why is the Organic-Lock material washing out?

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.

Why am I noticing an odour when using Organic-Lock?

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.

Will Organic-Lockeffectively stabilize native soil?

Organic-Lockis 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-Lockcan 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-Lockfor 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-Lockinto 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-Lockblended 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-Lockpowder into the top 3 inches using a rototiller or equivalent. Rates of Organic-Lockcan 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-Lockis 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-Lockbinder 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-Lockis 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.

Can Organic-Lockmaterial be installed immediately around the base of a tree?

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-Lockblended aggregate mix over the surface of the compacted structural soil.

Options (lowest to highest rates of permeability):

    1. Install full 3” of Organic-Lockblended aggregate mix over the structural soil up to the trunk of the tree.
    2. Start at 3” and taper to 2” or 1.5” to the trunk of the tree.
    3. Install the full 3″ of Organic-Lockblended aggregate up to the edge of the root ball of the tree, and proceed with unstabilized, aggregate (i.e. same aggregate as used elsewhere, however, un-blended with Organic-Lock) up to the trunk of the tree.

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.

On-Boarding/Aggregate Testing/Samples

Once we learn more details about the potential project or dealership, we would be glad to send you a trial-sized bag of Organic-Lockat no charge. This trial-sized bag will contain sufficient Organic-Lockto construct a 4’x4′ test plot when blended with your own aggregate.

Can you send me a sample of a suitable aggregate to blend with Organic-Lock?

Please refer to our optimal gradation guidelines for specifications pictures showing examples of suitable aggregates.

How Do I Order It?

Where can I purchase Organic-Lock?

Organic-Lock blended aggregates 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.


What types of delivery trucks are available?

Organic-Lockcan be delivered in a VAN, on a FLATBED.

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.

Absolutely NO double stacking of pallets.

*driver assistance is considered an additional charge by all carriers.

How many pallets fit in a full truckload?

The maximum number of Organic-Lockpallets that fit on a full truckload is 20 pallets (40,000 lbs).

Does your product pricing include freight?

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).

What is the standard packaging of Organic-Lock?

Organic-Lockis available is two package sizes:

    1. 50 lb bags at 40 bags per pallet (2,000 lbs total), hooded and shrink-wrapped
    2. 2,000 lb bulk bag (tote) on a pallet


What is the best way to store pallets or bulk bags of Organic-Lock?

It is ideal to store Organic-Lockindoors and properly covered to prevent contamination.

Can blended material be stockpiled?

Yes, Organic-Lockblended aggregate can be stockpiled, but it should be installed within 24 hours of blending. The natural moisture in the aggregate can compromise the Organic-Lockmixed within when it is not fully activated in an actual application. If a pile of blended material receives rainfall, the Organic-Lockwill leach out of the material and therefore compromise the mixture and eventual end product.

Can I package blended material in bulk bags for future maintenance activities?

If absolutely necessary, Organic-Lockblended 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.

What is the shelf life of the Organic-Lock?

As long as the Organic-Lockis properly covered and stored in a dry location (free from moisture and humidity), the Organic-Lockwill remain usable for 1 year.

How do I make Organic-LockBlended Aggregate?

What type of equipment is needed to blend Organic-Lock with aggregate?

You can use a pug mill, volumetric mixer, ready-mix truck, concrete mixer or bucket mix with a loader on a monolithic (hard) surface to avoid contamination. Refer to our installation video and our installation guidelines.

What is the best way to check moisture level of blended material?

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.

How do I install it?

What is an appropriate aggregate to use with Organic-Lock?

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.

What is the minimum installation temperature for Organic-Lock?

Please note that it is ideal for the daytime temperature to be at least 40 degrees F (5 degrees C) for installation of Organic-Lockpathway 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.

Can I blend and install Organic-Lock blended aggregate in the rain?

Do not blend in the rain. Do not install in the rain. Rainfall can have an adverse effect on the Organic-Lockif 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-Lockcould become fully activated and will stick to your equipment.

Can I spread the aggregate on the ground and till the Organic-Lock into the aggregate?

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.

If I can’t use a large static roller to compact the Organic-Lock blended aggregate when installing it in small, tight spaces, can I hand tamp it or use vibratory compactor?

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.


What is the longevity of an Organic-Lock blended aggregate surface?

The longevity of the Organic-Lockis 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-Lockis the most effective during this initial period of potential stress.  As the aggregate consolidates with traffic, weathering and overall compaction, the Organic-Locktakes a back seat and the aggregate takes on the heavy lifting.  We’ve seen successful installations lasting well over a decade.
