According to the soil problems and use, micropiles can be cased or uncased. The central reinforcing bar and cementitious grout, after put, facilitate weight transmission into your bearing soil or rock.
Through the amplified bond worry resultant through the simultaneous drilling and grouting operation, Hollow Bars are the reinforcement bar alternative in collapsing soil situations.
