Leaking Basement Waterproofing

Due to its below-ground nature, basements will have aggressive waters flowing down and into the basement. Therefore cement-based waterproofing that seals against positive and negative pressure provides total waterproofing protection.

For any water/moisture penetration occurring in your basement we recommend using cement-based products such as Drizoro Maxseal Foundation or Drizoro Maxseal Flex.

Both of these products will seal against positive and negative pressure, providing total waterproofing protection to concrete, bricks and blocks. However, the Maxseal Foundation does not allow for movement and may crack with cyclic movements. Maxseal Flex allows for movement and will not crack under movements in substrates caused by ‘house settling’ over time.

We recommend the use of the following products:

ACTFLEX 988 (Cementitious)


  • Maxseal Flex Kit
  • Maxseal Foundation
  • Drizoro Brush Applicator
