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. With an embedment depth of only 30mm the PENTAFLEX KB® metal water bar system is able to withstand water pressures 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 2 m 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. Placement is simple with units simply lapped along the concrete length and without the need to plan day joints for concrete pours.
