Product Overview
What is CLAYCRETE II?
CLAYCRETE II is a proven soil stabilizer used in a wide range of applications—from road bases and surface treatments to grain storage floors and runways. Designed for all types of clay-rich soils, it delivers lasting strength, durability, and performance where it matters most.
Why CLAYCRETE II?
CLAYCRETE II is a patented, one-time solution designed specifically to stabilize the clay portion of your soil. It creates strong, flexible, and long-lasting pavements by bonding the clay particles into dense, interlocked layers—reducing voids and increasing strength and water resistance.
By simply re-adding water to reach Optimum Moisture Content (OMC), the material can be reshaped or compacted again with the same reliable results. CLAYCRETE II works through a natural reaction with clay, leaving no binders, polymers, or residues behind—nothing to break down, leach out, or harm the environment. Just lasting performance you can count on.
How CLAYCRETE II works
CLAYCRETE II strengthens pavements by targeting and stabilizing the clay particles within the soil. In any strong pavement, the non-plastic materials (like gravel and sand) provide structure, while the clay fills the smallest gaps. When left untreated, this clay can shrink and crack when it dries—weakening the entire road.
CLAYCRETE II changes that. Once applied, it reacts with the clay to control shrinkage and improve bonding. As the moisture evaporates, the clay tightens and grips the surrounding stone particles like structural “bones,” pulling the layers together and increasing strength in all directions.
The result? Pavements that continue to gain strength over time, with improved resistance to moisture and wear. The improvement can be tracked through rising California Bearing Ratio (CBR) values, making CLAYCRETE II a smart, lasting solution for high-performance road building.

CLAYCRETE II – A unique solution for clay soil stabilization
CLAYCRETE II is specially engineered to deliver optimal results in soils with a Cation Exchange Capacity (CEC) between 50 and 400—commonly found in materials from local gravel pits. It balances strength, flexibility, and cost-effectiveness, making it ideal for sealed and unsealed roads, airstrips, structural floors, and more.
When CEC values are higher than 400—typically due to high clay content and plasticity—CLAYCRETE II may still be effective, but test sections are recommended. Our technical advisors can help assess your project and recommend adjustments when needed.
In cases of extreme plasticity, adding well-graded, non-plastic material (like 2–20 mm crushed stone) can improve the particle size distribution, increasing structural strength while keeping the benefits of clay’s natural binding.
Best of all, CLAYCRETE II is certified environmentally safe—making it ideal for use in sensitive areas such as national parks, game reserves, and protected zones. Strong, stable roads without environmental compromise.
