Aggregate Binder

Aggregate Binder

A revolutionary high-performance stabilizer and binder, the strongest organic binder on the market today.


Organic-Lock is the product of extensive scientific research. Designed for stabilizing aggregate surfaces, Organic-Lock's functionality allows you to create natural, aesthetically pleasing, permeable surfaces that hold up to extreme conditions.

The result? an environmentally-friendly binder that resists erosion while simultaneously remaining water permeable and maintaining strength and stability.

How Organic-Lock Works

When water comes into contact with an Organic-Lock blended aggregate, the water is absorbed by the Organic-Lock binder. The binder swells in size and grips onto surrounding aggregate particles, holding them together creating enhanced stability and significantly reducing erosion.

Once the gel forms to its maximum swell volume, it is unable to take on any new water so the excess water passes directly through the system down into the groundwater table. Over time, the gel releases its water through evaporation into the atmosphere and through percolation into the groundwater table…recharging the system to be ready for the next rainfall.

Rainfall Erosion Testing

The core focus for the development of the Organic-Lock formulation is on its ability to resist erosion due to excessive rainfall. Envirobond uses a customized rainfall simulation device that provides consistent and comparative stress to each sample studied.

By preparing samples that are subjected to a controlled rainfall simulation, Envirobond’s researchers have been able to understand the relationship between the binding strength and its ability to resist erosion. This has lead to a patented formulation making Organic-Lock the strongest organic binder on the market today.

Water Permeability

Traditional surfaces like asphalt or concrete are often installed to resist erosion, however they are also commonly impermeable to water.

Organic-Lock offers an ideal solution of being stable and also water permeable. When water comes across the Organic-Lock blended system, it easily permeates the pores of the aggregate.

Aggregate Stability

Organic-Lock blended aggregates derive much of their strength from the aggregate itself. The gel works best with the natural interlocking ability of well-graded crushed aggregate particles to create an optimally structured surface.

Only aggregates that meet our optimal gradation guidelines, which specify a detailed matrix of particle size distributions, are approved to become Organic-Lock blended aggregates. We determine this using a simple sieve analysis.

Organic-Lock Profile Projects

Organic-Lock blended aggregates have been successfully installed in projects for the last 15 years and are rapidly becoming the trusted environmentally-friendly pathway and surface solution for landscape architects, contractors and dealers around the world.

Water Permeable

On contact with water, Organic-Lock creates a gel that binds the aggregate particles together and allows excess water to pass directly through.


Our environmentally friendly Organic-Lock binder is the strongest organic binder on the market today. Organic-Lock is made from 100% naturally occurring materials.


If cracking occurs, rain water reactivates the Organic-Lock allowing the surface to self- heal and naturally fill any cracks

Resists Erosion

Organic-Lock is particularly effective on sloped surfaces where pathways and other surfaces are most prone to washouts and rutting due to fast moving water.

Easy Maintenance

Material can be re-worked by adding water first (which reactivates the Organic-Lock gel), followed by scarification and re-compaction.

Natural Aesthetic

Organic-Lock offers the sought-after natural aesthetic of aggregate surfaces, while still maintaining the stability associated with non-aggregate surfaces.
