After structural integrity, the next most important factor in building and construction is waterproofing. Waterproofing systems protect against water intrusion with the goal of maintaining long-term structural durability, surface protection, prevention of mold and mildew buildup due to dampness, and ultimately occupant comfort in buildings.

BASF polymer dispersions help impart numerous features to commercial waterproofing membrane systems such as but not limited to water resistance, moisture vapor permeability, waterproofing membrane strength, elongation, flexibility, crack-bridging and importantly, adhesion to the underlying substrate.

Interested in Polymers & Additives for Waterproofing?

BASF products are used in three main waterproofing technology categories:

  • Ready-to-use mastics
  • Traditional polymer-modified asphaltic waterproofing
  • High-performance two-component cementitious mortars

In certain applications these liquid applied technologies are preferred over conventional roll-on membrane sheets (e.g., made from bitumen, EPDM, HDPE, PVC or TPO) and over more costly reactive chemistries such as crystalline waterproofing and PU/polyurea/epoxy based systems.
