They may be made utilizing high strength metal casing or threaded pipes, and will be filled with concrete grouts and metal reinforcement. Often, micropiles may also be built applying concrete or timber.
The grouting is began through the substratum and follows an identical tremie grouting procedure followed in standard piles.
The strategy of drilling that will be utilized is decided from the soil style, rock circumstances, and application.
