What is PRECON PRECON is a composite sheet membrane comprised of a non-woven fabric, elastomeric membrane that is used for waterproofing vertically and horizontally. 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. Uses PRECON is used as a blindside membrane in vertical applications where access to the positive side is limited. The membrane can also be used for horizontal applications for underslab/blindside waterproofing and vaporproofing.…

Waterproofing
One of the largest problems facing structures today is water infiltration. When water and water vapor are able to seep into structures, it can contribute to mold growth and the durability of the structure. As below-grade waterproofing is critical to the long-term performance of a structure, it is essential this is addressed with a complete waterproofing system designed and constructed specific for the structure. According to The Concrete Network, “draining any water away and ensuring a dry interior space below grade can be relatively simple or fairly involved depending on geographic location, climate, topography, soil/water table conditions, and depth of…
