Waterproofing in Residential Construction: Why Detailing Matters

A practical overview of waterproofing risk areas, workmanship and checks in residential construction.

Water follows weak details

Terraces, toilets, balconies, sunken slabs, external walls and service penetrations are common areas where detailing matters.

Preparation matters as much as product

Surface preparation, slopes, junction treatment, curing and protection of completed waterproofing influence performance.

Testing should happen before finishes hide the work

Appropriate ponding or other specified tests can help identify issues before tiles and finishes make repairs more disruptive.

Maintenance remains relevant

Even well-executed systems need proper drainage and maintenance over the life of the building.
