To provide a ground hardening material with which a uniform hardened ground layer having a large enough diameter is created in the ground and ground stabilization and water cut-off are achieved reliably and effectively and a method of construction of the hardened ground layer using it.
The ground hardening material which comprises at least cement and water has a viscosity of ≤100 mPa s and a dissipative time of foam of ≤1 min. The construction method with which a hardened ground layer is created by inserting the injection head 1 into the objective ground and injecting the material into the ground from the injection head 1 with pressurized air in a way that the air surrounds the material uses a ground hardening material consisting at least of water and cement and having a viscosity of ≤100 mPa s and a dissipative time of foam of ≤1 min.
