Common Waterproofing Problem Areas in Kathmandu Homes
Terrace and Roof – Often the most exposed, these areas suffer from cracks and pooling water.
Bathrooms and Kitchens – Areas with frequent water use can allow seepage through floors and walls.
Interior & Exterior Walls – Poor drainage and moisture build-up cause bubbling paint and wall cracks.
Basement and Foundation – Vulnerable to underground water and poor slope management.
Balconies and Water Tanks – Exposed joints and improper drainage lead to persistent dampness.
Effective Waterproofing Methods Used in Kathmandu
While there are various methods available, professionals in Kathmandu typically use the following solutions based on problem area:
Silicon application for sealing windows, minor truss leaks, and frames.
Torchshield membrane for flat roofs and medium surface cracks.
Torchshield with GI sheet for large or exposed rooftop gaps.
Polymer grouting in bathrooms and tiles for internal leakage prevention.
Membrane coating on concrete surfaces to prevent seepage from rainfall.
Damp proof painting for interior and exterior wall protection.
Super latex slurry for mortar joints and basement leak-proofing.
