Waterproofing vs Dampproofing

Through out history, there has been some confusion between what dampproofing and waterproofing is. However the facts as stated by the International Residential Code provide some clarity.

Cool Facts
  • The only exception to not have a drainage system installed on your home under the International Residential Code is, "A drainage system is not required when the foundation is installed on well-drained ground or sand-gravel mixture soils according to the United Soil Classification System, Group I Soils, as detailed in Table R405.1." This means that all waterproofing methods are considered damp proofing if there is no drainage system installed unless on well-drained soil or sand. However, at that point you may require and engineer to approve the soil

  • The International Residential Code states, "Drains shall be provided around all concrete or masonry foundations that retain earth and enclose habitable or usable spaces located below grade"

  • SUPERSEAL Dimpled Membrane can be both damp proofing and waterproofing. When installed with a perimeter drainage system it is considered waterproofing, when installed without a perimeter drainage system, it is considered damp proofing. However, under the International Residential Code this is true for all below grade foundation coatings or membranes

  • Wet basements may decrease your homes value by 10-15%

  • A home must have the ability to breath. This means keeping external moisture out while allowing internal moisture to escape

The SUPERSEAL Solution

SUPERSEAL 's Dimpled Membrane is unlike any type of damp proofing or waterproof coating. According to the International Residential Building Code, SUPERSEAL’s membrane is considered waterproofing. SUPERSEAL 's Dimpled Membrane has countless benefits but the most important is its ability to let your home breathe. SUPERSEAL's 24-mil high-density membrane not only keeps external water out allows internal moisture to escape to the footing drain for removal. It also removes 100% of the hydrostatic headwater pressure of the face of the wall and is unaffected by alkalines in soils and concrete and is 100% environmentally friendly.
