Waterproofing isn't priced by area alone. The roof or tank condition, the preparation it needs and the suitable system all change the cost. Understanding these factors helps you compare quotes fairly.
Roof waterproofing factors
Key factors:
- Roof area and number of levels
- Removing old waterproofing or tiles
- Treating cracks, junctions and edges
- Correcting slopes and drains if needed
- System type: waterproofing, thermal or both
- Re-tiling or a protective layer on top
- Access and moving materials
Tank waterproofing factors
Tank size, type and location, wall and existing-lining condition, the number of cracks and leak points to repair first, and whether the material suits contact with drinking water.
What a quote should state
Ask for the area, removal and preparation work, the system, and whether protection, finishing and drain repair are included. The cheapest quote may leave out the preparation that success depends on.
