About Water Tank Waterproofing
Water tank waterproofing treats tank surfaces and details to reduce leakage and protect the tank structure.
System selection depends on substrate, moisture condition, exposure, movement, drainage, existing finishes and access. Inspection and preparation are important parts of a suitable approach.
Common Problems & Warning Signs
These symptoms may indicate a need to inspect the affected area. Similar symptoms can also have other causes, so the source should be checked.
- Water loss from visible leakage
- Dampness around tank walls
- Seepage at construction joints
- Cracks inside concrete tanks
- Leakage around pipe connections
Causes & Risk Factors
Water penetration can develop from construction details, ageing materials, environmental exposure and maintenance issues. Common causes include:
- Shrinkage or movement cracks
- Poor construction joints
- Defective pipe penetrations
- Deteriorated internal coating
- Inadequate concrete or previous repairs
