We are looking at an "ionic polymerisation" additive to stabilise and "waterproof" soil subgrade materials. The distributor claims the polymer links together and forms a bond which increases the density of the material, while reducing the porosity of the soil matrix making it resistant to water etc etc. Has anyone used polymers in soil stabilisation for pavements. The distributor also suggests the addition of cement (2-5%) with the polymer as an additive. Recommended polymer amount is 1.67 litres per square metre per 150mm depth.
