Basement Interior Walls


Water coming into your basement is generally a result of water pooling around your foundation.  If you can keep most of the water away, waterproofing from the inside can work for you.  It's always best to waterproof from the exterior but not always possible.



  1. Ensure a clean, dry surface
  2. If you have deep cracks, fill with a Crack Injection Kit
  3. Bridge joints, cracks, seams etc., with Liquid Rubber Geo-Textile
  4. Build up heavy coats to achieve required thickness
  5. See Products Used below



  • Liquid Rubber Foundation Sealant can be painted over with standard wall paint
  • Ensure rain gutters have extensions taking water away from your home
  • Build grade/earth/dirt/drainage sloping away from your home
  • Weeping Tile can be installed to direct water away
  • Dust or dirt can cause loss of adhesion
  • Product stays soft, flexible and may have some tackiness
  • Apply next heavy coat when product is dry to touch and nothing is wet underneath.  Tacky is ok
  • Use up all required material to ensure a long lasting membrane
  • Apply above 10C/50F
  • Remove painter's tape while coating is still wet



  • Coverage varies by product used.  See Product Page for specific coverage of that product
