Kemper System monolithic waterproofing membranes adhere over the entire surface and eliminate the need for pitch pockets, term bars, fasteners and adhesives, providing extreme bond strength and seamless performance properties.
Kemper System is ideal for flashing any difficult architectural element or configuration. Our membranes also are unaffected by ponding water and ice conditions while remaining permanently resilient to compensate for movements in the structure due to thermal expansion of different materials. Where the competitorís systems typically fail; Kemper System ensures long-term protection at all transitions, penetrations and terminations.
Eliminate leaks in the IDS Center’s Crystal Court, which had leaked since its initial construction. The Crystal Court, part of the landmark IDS Tower of the Minneapolis skyline, consists of eight different levels with a total of 289 skylights separated by a narrow ten inch wide gutter. The design resulted in a dramatic but problematic atrium. The Crystal Court serves as a meeting location and transit hub for 50,000 pedestrians who walk through the Crystal Court on a daily basis, and is an integral part of the raised pedestrian bridge system in downtown Minneapolis.
Two test areas, totaling 15 skylights, were waterproofed with Kemperol membrane to confirm system performance. Following three years of watertight performance in the test areas, the remaining 274 skylights were waterproofed, completing the project.
