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.

Benefits

Project Profiles:

City Hall - New York City

Challenge
Integration of new copper roof bridging extensive gutterway conditions with historic terracotta balustrade parapet system to resist damage from standing water and ice.

Solution
Installed Kemperol membrane directly over copper seamed roof to fully adhere
to top surface terminating membrane at multi-detailed parapet base.

 
Raymond F. Kravis Center for the Performing Arts – West Palm Beach, Florida

Challenge
Large wooden internal gutter system between metal roof sections leaked into performing arts center below.

Solution
Kemperol BR seamless membrane installed over wood gutter structure and
terminated under metal flashing pieces on either side of the gutter resulting
in a complete edge-toedge watertight solution.

 
The Mayfair House – Coconut Grove, Florida

Challenge
Copper gutter within metal roof system leaked into hotel common area below.

Solution
Kemperol BR seamless membrane installed directly onto copper gutter and
terminated under metal panels to provide complete encapsulation of gutterway system.

 
Capitol Building – Olympia, Washington

Challenge
Installation of new plywood decks and waterproofing system for a leaking gutterway at tension rings that surround the state’s Capitol Building dome.

Solution
Installed monolithic Kemperol BR membrane to the project, providing
an extremely effective watertight solution.

 
Smithsonian Air and Space Museum – Washington, D.C.

Challenge
Water penetrated through glass and metal seam roof due to failure of sealant at metal seams. Sealants required constant maintenance and were replaced
every several years.

Solution
Kemper System membrane provided a long-term solution by lining 1,000 linear feet of gutters at the skylight roof.

 
U.S. Post Office – New York City

Challenge
The U.S. Post Office required a long-term waterproofing solution as an
alternative to replacing an extensive, leaking, interior court skylight system.

Solution
After minor surface preparation, applied edge-to-edge application of Kemperol membrane on entire glass and copper skylight system, realizing tremendous cost-savings.

 
75 Henry Street – Brooklyn, New York

Challenge
Typical challenges of most applications where planters are involved are the
numerous rebar that penetrate up through the deck to secure vertical walls. Most systems don’t have the ability to wrap those penetrations and treat each structural dowel as an individual flashing.

Solution
Kemper’s ability to detail each individual rebar eliminated the possibility that water would seep through the planter walls and down to the existing plaza.

 
Benjamin Franklin House – Philadelphia, Pennsylvania

Challenge
The historic landmark structure experienced severe leaks at the water table and parapet walls on the roof level.

Solution
Because of the difficulty and expense in accessing this area for maintenance, the building owners chose the Kemperol V210 membrane for a problem-free, long-term solution.

 
IDS Center - Minneapolis, Minnesota

Challenge
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.

Solution
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.
