Bathroom Waterproofing: Find the Source Before Repair
Bathroom leakage can involve plumbing, floor traps, penetrations, joints or the waterproofing layer.
ODS Construction Chemicals · Waterproofing information
What to record
Bathroom leakage can involve plumbing, floor traps, penetrations, joints or the waterproofing layer. Note whether it follows shower use, other water use or rain. Where another unit is affected, coordinate access through building management and the relevant occupants.
Before choosing a repair
A repair may be localised or may require removal of finishes to reach the failed layer. Neither “always hack” nor “never hack” is a reliable promise before assessment. Confirm preparation, continuity around joints and drains, curing, testing and reinstatement in the written scope.
Discuss the scope
ODS Construction Chemicals focuses on waterproofing, supported by concrete repair, flooring and finishing. We also consider selected renovation and construction projects. Send the location, photographs and proposed scope to confirm whether we can take on your project. A guide is not a quotation or a promise of a particular method, product or completion date. Where a project proceeds, the written scope sets out the work and any warranty offered.
