Grouting

Gravity grouting involves the drilling of holes up to the full depth followed by the pumping of grout under gravity near to the bottom of holes. Gravity grouting is generally suitable for the grouting of larger voids and cavities that grouts can reach through gravity

Pressure Grounting

Pressure grouting is a ground improvement or soil stabilization technique that involves injecting a fluid-like material under controlled pressure at strategic locations, via single or multiple ports, into soil or rock strata to improve their mechanical properties
