Hyperseal DP-2005 (10m roll)

Hydrophilic rubber waterstop for low movement construction joints

Hyperseal DP is a hydrophilic waterstop which can be applied against existing concrete and can be simply installed by nailing or using a hydrophilic adhesive. In contact with water, hydrophilic strips react and swell by up to 300% of their original dimensions to form a compression seal.
