Waterproofing
Waterproofing is invisible work — its mistakes surface years later, in the most expensive way possible.
- System Matched to Surface: Membrane, Bituminous or Liquid
- Verified with a Ponding / Smoke Test
- Drains, Penetrations & Corners Hand-Reinforced
- Standard Job Completed in 3–7 Days

Foundation walls, terraces, roof spaces and wet rooms all face different water loads, and each needs a different system. At EMC Decor we start with moisture measurement and crack mapping, then match the system to the surface: crystalline/cement-based membrane for pressurised water, PVC or bituminous membrane for terraces and balconies, two-coat liquid membrane for wet areas.
Before anything is closed up, we verify the seal with a ponding or smoke test and document it with photos. Detail points — drains, penetrations, corners — are hand-reinforced, since roughly 80% of leaks start there, not on the flat surface. A standard job takes 3–7 days.

The Challenges You Face, Our Fix
RISK 01: Pressurised groundwater seeping through foundation walls
SOLUTION: We apply a crystalline or cement-based membrane for pressurised water and verify with a ponding test before closing up.
RISK 02: Hidden leaks starting at drains and pipe penetrations
SOLUTION: We hand-reinforce these detail points — where 80% of leaks originate — with collars and an extra layer.
RISK 03: Terrace and balcony waterproofing cracking from freeze-thaw cycles
SOLUTION: We use flexible PVC or bituminous membrane with designed expansion joints to withstand freeze-thaw cycling.

View PricingFrequently Asked Questions
Which areas actually need waterproofing?
Bathrooms, terraces, balconies, roof spaces and basement/foundation walls come first — these are in direct or constant contact with water.
Can tiling start right after waterproofing?
No — each coat waits out the manufacturer's cure time and must pass testing before any finish goes over it; we never skip this step.
Can you repair an existing leak, not just prevent new ones?
Yes — we first locate the source (using a moisture meter if needed), then open up and re-waterproof that section.
What does the warranty cover?
Waterproofing done with the material we supply carries a 12-month warranty; the test report is part of your handover file.
