Description

CORKJOINT Jointflex® is a closed cell, crossed linked, non-absorbent polyethylene expansion joint fillerboard for use in expansion and isolation joints in concrete and masonry structures. Jointflex® is non-absorbent and has excellent properties allowing it to be used in water retaining and excluding structures where potable, salt, chlorine and sewerage water is present.
