Whether you are trying to stop an active leak, preserve and protect the integrity of your home or structure, or are converting your basement into a livable area. Protecting your foundation with Liquid Rubbers waterproofing solutions is an effective and affordable investment. No one wants to deal with the costly repairs, damages, and inconvenience that result from water intrusion. Use Liquid Rubber products and sleep soundly knowing you are protected.


  1. 1. Inspect the foundation for cracks and spalls, and voids (around pipe protrusions, etc.). Look for efflorescence and deterioration on both the exterior and the interior for evidence of leaks.
  2. 2. Be sure your concrete is completely cured (28 days is the industry standard).
  3. 3. Make any necessary repairs and allow to cure (when using concrete, mortar, caulking, etc).
  4. 4. Remove silicone, coal tar, and loose/flakey paints or coatings if any.
  5. 5. Prep the surface using a pressure washer, or by mechanical abrasion. (be cautious when introducing water, as the surface must be completely dry for application and cure). Ensure the surface is clean and dry and free of oils or other contaminants.
  6. 6. Tape off or otherwise mask area’s you wish to protect from the coating.
  7. 7. Bridge joints, cracks, around protrusions (vents, skylights, etc) using Liquid Rubber Seam Tape (Apply a coat of your selected waterproofing over the Seam Tape, going at least 2 inches beyond the edges and allow to dry), or our Geo-Textile applied via the 3-course method. If expansion joints are present, discuss application with your Liquid Rubber rep.
  8. 8. Once detail coats are dry, begin your field application. Apply your selected waterproofing to the entire surface. Allow adequate drying time and inspect for pinholes, blisters, etc, and repair as necessary before applying your next coat. Talk to your Liquid Rubber technical rep to determine which product suits your application.
