Use of polymers to improve soil subgrades
Use of polymers to improve soil subgrades
(OP)
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.

It will work great if you add 2-5% cement....but then, you could add 2-5% cement without the polymer and achieve the same result.
Usually not worth the cost...other methods available to achieve same or better results.

I feel "snake oil" is appropriate, but I should have asked if anyone knows of testing such as CBR, Atterberg Limits or UCS over a period of time which indicates the improvement, or lack thereof, when using polymers with and without traditional additives such as lime or cement.
