HYPER-SEAL DP2010 Hydrophilic Synthetic Waterstops A complete Range of High Performance Hydrophilic Waterstops HYPER-SEAL DP2010 waterstops 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. Benefits Active protection – HYPER-SEAL DP2010 hydrophilic synthetic waterstops swell in contact with water to form an effective compression joints. Simple application and jointing techniques. Slow expansion rate to prevent damage to freshly placed concrete during curing. Retains original shape after repeated and contraction. Swelling properties unaffected by long term wet/dry cycling. Sustains effective seal in wet conditions. Description 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. Installation 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. Application Method Health and Safety There are no known hazards associated with HYPER-SEAL during normal use. Refer to product Safety Data sheet for detailed information.
