Dam Construction - Soil Stabilisation

Dam floor and wall stabilisation can be achieved by using DUSTDOWN in the surface of the dam materials to allow quicker access when applying liners and preventing erosion during construction. The DUSTDOWN allows the in-situ materials to remain firm even after rain. This in turn allows machinery to be driven over the surface without damaging the surface in time for vinyl liners to be placed.

Furthermore, as it prevents water entering the in-situ materials, it prevents water induced erosion of the surface prior to lining the walls and hence reduces the cost of having to reform the even surface required. It also has the beneficial effect of sealing the soil under the liner in case a leak occurs.
