Formdex 2010 (Misc)

Formdex 2010 is a high-quality hydrophilic water stop that is used primarily in providing a water seal at construction and non-movement joints. Formdex 2010 is made from high performance polymeric composites that have delay swelling action. The swelling action is the result of water reaction within the polymer matrix, expanding in volume without altering its homogenous structure. It can swell up to 200% of its original volume under constant water immersion to form an effective compression seal which creates a positive seal in the construction joint even under high water pressure. It will not transport water through its polymeric matrix and thus not act as a capillary duct.
