Our Waterproofing & Caulking Process
We don't cut corners. We waterproof properly — guaranteed.
Step 1 — Site Inspection & Planning
We assess substrate condition, moisture levels, falls, drainage, old membranes and risk areas.
Step 2 — Surface Preparation
We clean, patch, grind and prepare all surfaces correctly so the membrane bonds perfectly.
Step 3 — Waterproofing Application
Class III membrane application with multiple coats, correct drying times, reinforcement in corners/joints, shower base waterproofing and wall-to-floor sealing.
Step 4 — Certification
You receive an official compliance certificate — required for insurance and future resale.
Step 5 — Tiling (If requested) & Caulking
We complete the tiling with laser precision (if part of the job). Then we apply premium silicone with razor-sharp lines around tiles, edges, corners, and fixtures.
Step 6 — Final Inspection & Handover
We check every corner, joint and seal. Your wet area is clean, protected and built to last.

Do I need licensed waterproofing?
Yes. It is illegal for unlicensed installers to waterproof bathrooms, and insurance will not cover leaks from illegal waterproofing.
How long does waterproofing take?
1 day to apply + drying time. Tiling can begin after curing.
Does caulking need to be replaced?
High-quality silicone lasts years, but bathroom humidity eventually requires replacement. We use long-lasting mould-resistant silicone.
Can you fix old failed waterproofing?
Yes — we fix and re-waterproof damaged wet areas.
Do you work with tile selection?
Yes — we help with choosing the right tiles for wet areas.
