Waterproofing questions, answered.
Short, contractor-side answers on diagnosis, method, testing, access and the standards we work to. If your question is not here, send it through the contact form.
How do I know if my bathroom needs waterproofing rectification?
Repeat dampness on the ceiling below, staining around the floor trap or pipes, damp skirting in adjacent rooms, or swollen flooring next door are all signs the wet-area membrane is failing. A short inspection with moisture mapping confirms the scope before any hacking begins.
Can the leak be fixed without hacking the bathroom?
Sometimes — when the source is the WC base seal, a pipe joint, a damaged pan collar or grout failure, targeted repair without full hack-out is possible. When the membrane itself has failed, hacking back to the screed and reinstating the membrane is the right scope. The diagnosis decides.
How long does a ponding test take?
A 24-hour test is the typical wet-area protocol once the membrane has cured to data sheet. Water level is marked, photographed and checked at the end. The test record forms part of the handover documentation.
What is the difference between PU injection and surface waterproofing?
PU injection treats a specific active leak at a crack or joint from inside. Surface waterproofing protects a wall or slab from outside. They are complementary; on most live leaks we use both — injection first to stop flow, then a surface system over the wider area.
Do I need a waterproofing inspection report?
Yes if the scope is unclear, multiple parties are involved (strata / MCST / unit owners), or there is a history of repeated rectification. An independent inspection report sets the hack-out boundary and lets rectifiers quote on a like-for-like basis.
Do you perform statutory Periodic Facade Inspection?
A building owner must appoint a Competent Person to conduct statutory PFI. Ezzogenics does not act as the appointed Competent Person. For access and inspection-support enquiries, see facadeinspection.com.sg. Rectification scopes that follow a PFI report — crack repair, joint resealing, external wall waterproofing — are documented on this site.
Can you waterproof a roof or facade without scaffolding?
Often yes. Boomlift, gondola or rope access — chosen based on building height, ground access and surrounding activity — are alternatives to traditional scaffolding. Access selection is part of the method statement. Related context at workatheight.sg and rope-access-singapore.com.
Which standards do you work to?
SS 637:2018 Code of Practice for Waterproofing of RC Buildings, BCA Waterproofing for Internal Wet Areas, BCA CONQUAS and Quality Mark for wet-area water-tightness, and SS 677:2021 for precast joints and weather-tightness where relevant.
How long is a waterproofing job?
A bathroom rectification typically runs 5 to 10 working days including hack, membrane, cure, ponding test, screed protection and retile. A roof job depends on area and access. External wall coatings depend on access method and weather. A range is given with every quote.
Do you provide warranty?
Warranty terms depend on the system applied and the substrate condition. The exact warranty length is part of the quote, not advertised generically — claims like "lifetime warranty" rarely reflect the actual contractor-side obligation.
