TileRite Durabase Anti Crack Matting 5m roll. Dimensions 5m x 1m = 5 SqM. Durabase matting is your simple solution to crack suppression and waterprofing. Prevents substrate cracks caused by substrate movement. 100% waterproof (when used in conjunction with durabase joint tape). Bridges cracks in substrates. Faster & easier working filling the wide clover leaf holes. Batter resistance on heated surfaces with rapid expansion and contraction. Wide clover leaves means more adhsive in contact with the base.
