Basement & Cellar Tanking Solutions 

Tanking is a specialist waterproofing solution used to protect below ground spaces from water ingress. It is typically required in basements, cellars, and areas exposed to constant moisture pressure from surrounding ground levels.
At ProMaster Gecko, tanking is only recommended following proper inspection to ensure it is the correct solution for the structure.

Why Tanking Requires Proper Diagnosis

Below ground water ingress can occur for several reasons, including groundwater pressure and structural weaknesses. Applying tanking without understanding how moisture is entering the building can lead to system failure or ongoing damp problems.
Our approach focuses on identifying the cause first, ensuring tanking is only specified where it is genuinely appropriate.

Where Tanking Is Commonly Used

Tanking is typically considered in properties where moisture is entering below ground structures and affecting internal spaces.

  • Basements and cellars below external ground level

  • Persistent moisture affecting retaining walls

  • Water ingress through floors or lower wall sections

Our Tanking Process

  • Inspection and moisture assessment

  • Identification of water ingress pathways

  • Selection of an appropriate tanking system

  • Careful installation and detailing
