Plaintree Systems Inc. Announces Orders of Over U.S.D. One Million for Its Flood Proof Foundations

Plaintree Systems Inc (NPT - CNQ, PTEEF - OTCBB), (NPT - CSNX), today announced that in the last four months its Triodetic division has received contracts worth more that 1.0 million dollars US for the engineering and manufacture of their tubular foundation system, for application in areas of unstable soil conditions in Alaska Russia and the Canadian Arctic.

Triodetic's has a long term relationship with FEMA ( Federal Emergency Management Agency) for the use of its foundation technology in flood relief areas. Its innovative foundation system will be featured at the upcoming AIA (American Institute of Architects) tradeshow later this month in San Francisco, CA. Triodetic also has long standing relationships with HUD (U.S. Department of Housing and Urban development) and CMHC (Canada Mortgage and Housing Corporation).

David Watson, CEO of Plaintree, says that, "At the AIA, Triodetic will highlight the benefits of this foundation system for applications such as the Louisiana rebuilding efforts. They are looking for an inexpensive and robust system that will allow residences to be elevated up to 8 feet above the ground level".

The foundation consists of a galvanized steel frame, which is torsionally stable and elevates the building above the flood plane between 3 feet and 8 feet. The tubular frame gives strength to the building and is adjustable to accommodate uneven terrain. Several hundreds of buildings have been successfully supported by the Triodetic(r) Multipoint Foundation Frames by over the last 30 years and growth in this market has been strong.
