Every construction project will at some point require a some form of waterproofing. At Construction Techniques we can cover all your waterproofing requirements for both new build and existing structures. We are experienced, trained installers for all types of waterproofing including Types A, B & C, on a wide range of structures including:

  • Basements.
  • Retaining walls.
  • Lift Pits.
  • Podium Decks.
  • Plant rooms.
  • Bunds.
  • Swimming Pools.
  • Movement joints.

Waterproofing products and systems can come in many forms and not every product is suitable for every project. Therefore it is important to engage with a waterproofing expert as early in the design stage as possible. Construction Techniques assist and can help and guide designers and contractors thorough this process.

Waterproofing Solutions


When constructing basements, waterproofing should be given the highest level of priority (new or existing), both during the design and construction phase.

For New Builds we can work at the design phase to ensure that any waterproofing challenges are met before groundworks commence. For existing basements, we can provide a variety of solutions covering Type A, B and C systems.
