Organic-Lock™ is the product of extensive scientific research

Rigorous testing has been performed in the laboratory to develop the optimal scientific formulation for the patented binder.

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

Optimal Scientific Formulation


When water comes into contact with an Organic-Lock stabilized 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.


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.

The water permeability rate of Organic-Lock™ stabilized aggregate, determined by an Independent ASTM standard double ring infiltrometer test, shows a rate of 0.85 inches per hour.


Organic-Lock™ stabilized 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™ stabilized aggregates. We
determine this using a simple sieve analysis.

Simple Maintenance


The Organic-Lock™ gel activates each time it comes in contact with water, which allows for the blended aggregate to be physically broken up, re-worked and returned back to its initial state. This self-healing nature allows for a simplified maintenance procedure that leaves no sign of the maintenance itself.

For example: If you have to run an irrigation line below your finished pathway, all you need to do is add water, dig the material up, put down your irrigation line, spread the material back in place, then water and compact it back to new.
