Proper waterproofing is an investment in the longevity and safety of your building. Avoid these common mistakes to protect your property from water damage.
- Ignoring water damage — standing water and odour can signal hidden leaks; ignoring them invites dampness that weakens the structure.
- Incorrect sloping — ground or roof slopes towards the structure cause water to collect.
- Relying on sealing paste — patching cracks with paste is not a lasting fix; use professional waterproofing and quality products.
- Inadequate surface preparation — surfaces must be clean and dry for materials to adhere.
- Uneven application — inconsistent coats create weak spots.
- Improper mixing — always follow the manufacturer’s mixing ratios.
- Insufficient coverage — cover all vulnerable areas generously; gaps cause leaks.
- Ignoring expansion joints — joints accommodate movement; neglecting them leads to cracks.
- Not addressing structural cracks — repair cracks before applying waterproofing.
- Using incompatible materials — mixing incompatible products compromises effectiveness.
