Pentaflex KB Structural Waterproofing System

PENTAFLEX KB® metal water bars are fully coated on both sides with a special coating to provide reliable waterproofing at concrete joints. The bond between the special coating and new concrete prevents water infiltrating the joint and an embedment depth of 30 mm is enough to withstand water pressure of up to 5.0 bar. The high elasticity of the coating ensures reliable sealing when the concrete structural components shrink. PENTAFLEX KB® units are typically supplied in 2m lengths with a choice of 167 mm or 80 mm widths. The bonding surfaces are protected with a film on both sides that is only removed immediately before concreting. Units are simply lapped along the concrete length and without the need to plan day joints for concrete pours. NHBC recognition. ETA-15/0003
