Formdex Plus (Basement WP)

Formdex Plus is a cementitious waterproofing system consisting of cement, quartz sand and multiple activating chemicals. The waterproofing effect is provided by the penetration of various chemical components into the capillary tracts of the concrete by pressure of osmosis and reacts with moisture and free lime in the concrete, forming crystals which seal the capillaries and pores, thus preventing water penetration. Formdex Plus works equally as well when applied to or against the pressure of water.


Formdex Plus is used for any type of new or existing concrete structure to protect it against the penetration of water. It can be used in both interior and exterior applications. Application can be made by brush, or dry sprinkling to either lean concrete before laying the slab or on the surface of newly laid concrete.

Formdex plus can be used either exposed or concealed for:

  • basement walls and floors
  • bathrooms
  • underground shafts
  • water containment structures
  • garages
  • foundation walls and footings
  • tunnels
  • retaining walls
  • swimming pools
  • lift pits
