Acid Sulphate Soils

Acid sulphate soils can cause damage to concrete and reinforcing steel in situ. Graymont can supply products that are commonly specified to neutralize and condition acid sulphate soils prior to sub surface construction work taking place.

Acid soil

Important factors to consider when selecting the correct neutralizing agent include; safety during application, receiving environment for any water runoff, buffering capacity, solubility and purity of the material.  Certain types of limestone, quicklime and hydrated lime may be used as neutralizing agents for treating acid sulphate soils. The application of these materials is a technical area and customers should engage a qualified professional to ensure the soils are assessed correctly and mix designs and techniques are appropriate for the situation and soil conditions present.
