- Soil Injection |
|
Chemical soil injection is done to reduce the ability
of expansive clay soils to retain water, reducing "heave" in
soil and the damage it can cause. The varying
wet and dry cycles during the year cause the
realignment of platelets in clay soils. This
causes the soils to contract. Chemical injection
allows excess moisture to be drained away by
loosening the bond between molecules of water
and the platelets. Chemical injections change
the composition of the soil and reduce the expansion/contraction
cycles. Injections into the soil are made by
Power Jack with the aid of a high pressure insertion
process, with equipment designed and produced
specifically for chemical soil injection.
