Greenstone Introduces New Concrete Foundation Protection

NEW YORK, NY--(Marketwire - January 17, 2008) - Greenstone Holdings, Inc. (PINKSHEETS: GSHN) announced today that the Company has introduced a new product line MagneLine®-FP which is an innovative method to protect concrete foundations. With MagneLine-FP, the exposed face of the concrete foundation exposed to the elements, such as rain, salt, acid, and other chemicals, will be protected and will also protect surfaces from cracks with its Polymer Cement Mortar which is both flexible yet strong. MagneLine is so flexible that structurally unaffecting cracks of sizes up to almost 1/10" will not be visible. (See some photos:

"Although the housing market has slowed, 1.5 million homes are still being built every year and we believe that MagneLine-FP will make those houses more claim-free for the builders, an added marketing feature," said Sal Miwa, CEO of Greenstone.

MagneLine is distributed exclusively in the United States by Greenstone for Magne Corporation in Fukuoka, Japan.
