AKVASTOP INJEKTO system — injection hoses for concreting joints
Injection hoses for construction joints, butt joints and pipe-to-wall details: the joint is sealed by injecting a compound after concreting.
The DR repair waterstop is needed when the expansion joint of an already built buried or underground structure leaks and its sealing has to be restored. The rubber profile DR-250/50 works at water pressure of 0.29 MPa, the PVC-P profiles DR-210/30 and DR-230/50 at 0.33 MPa. DR-230/50 accommodates the largest movements: joint tension and transverse shear of up to 120 mm.
