HYPER-SEAL DP2010 is made with high performance synthetic elastomer strips. The swelling action is the result between water and hydrophilic groups, which are part of the HYPER-SEAL DP2010 molecular structure. Expansion of the waterstop creates a positive seal against the face of the concrete joint, this cause preventing water entry into the structure through the protected joints.
   HYPER-SEAL DP2010 waterstop can be applied against existing concrete and are simply installed by nailing or using a hydrophilic adhesive. In contact with water, hydrophilic strips react and swell by up to 250% above of their original dimensions to form a compression seal. Hydrophilic strips are suitable for installation in low movement construction joints. HYPER-SEAL DP2010 is used primarily for foundation walls slabs, slabs-on-grade, precast wall panels, manholes, pipe connections, box culverts, utility and wet wells, and potable water tanks.
Installation Process
Where the substrate is uneven, HYPER-SEAL DP2010 can be fastened in place using masonry nails at approx. 300 mm center. Care should be taken however to ensure that the substrate has sufficient strength to enable a mechanical fixing to be securely driven without damaging the HYPER-SEAL. Alternatively, a groove can be cast into concrete to facilitate application. HYPER-SEAL DP2010 is suitable for use in most weather conditions, but heavy rain or prolonged immersion will cause premature swelling. Should this occur, it will be necessary to allow it to dry out, or be dried with a hot air gun before concrete pouring takes place. HYPER-SEAL DP2010 should not be used in expansion joints, or any concrete section of less than 150 mm. widths..
