HydroBlocker Tekatrak Q1 is a sealing tube intended to force the formation of cracks in concrete as well as to seal them. It is used on the basis of a “white tub” principle - in the middle of a wall where the tube is placed we force the concrete to crack on that very spot. Thanks to its shape the tube seals such a crack.
Two diameters are available:
Q1 = 88mm (external 138mm) and Q2 = 175mm (external 235mm).
