APPLICATION NOTES

  • Always use an appropriate ConSeal Primer Product to avoid displacement of CS-235 during the concrete pouring. It may be necessary to utilize masonry nails or other mechanical means to hold the sealant in place on vertical surfaces
  • Place CS-235 Waterstop so that it is no closer than 2” away from the outer surface of poured structure. If a keyway is utilized, place the CS-235 into the bottom of the formed keyway area

ConSeal CS-235 Waterstop is a unique sealing compound designed to expand rapidly when exposed to moisture, making it a self-healing joint material for construction joint applications.
