WR MEADOWS – PRECON

Project: TTC Steeles West
Location: Toronto
Architect/Engineer:
Contractor: Structural Waterproofing
Situation:

 

Structural Waterproofing required the use of a blindside waterproofing membrane for the TTC Steeles West project.  On most projects, below-grade waterproofing is applied after the foundation walls have been poured, however, on this job this was simply not possible.  Structural Waterproofing sought out the expertise of Form and Build who offered the solution of using PRECON Blindside/Underslab membrane from W.R. MEADOWS. 

 

Solution:

PRECON is a composite sheet membrane comprised of a non-woven fabric, elastomeric membrane, and W. R. MEADOWS’ exclusive, patented plasmatic core (U.S. Patent No. 7,179,761). The plasmatic core is a seven-layer matrix designed for toughness and provides the lowest water vapor transmission (WVT) rating on the market. Once concrete is poured against PRECON and the concrete cures, a mechanical bond forms that secures the concrete to the membrane.
