Waterproofing is not painting membrane onto concrete. It is substrate science, detailing, sequencing and verification. Every VVS installation follows the same disciplined sequence.
Substrate Assessment
Moisture content, falls, cracking, laitance, contamination and existing membrane condition are assessed before any product is selected.
Preparation
Grinding, shot blasting, crack routing, patching and priming. Membranes fail on preparation long before they fail on product.
Detailing
Penetrations, drains, upturns, corners, movement joints and terminations are detailed to manufacturer specification first.
Membrane Installation
Torch-on, liquid-applied or sheet systems installed to specified wet-film and dry-film thickness across every coat.
QA & Inspection
Coverage records, batch numbers, photographic evidence and hold points documented through the installation sequence.
Testing
Flood testing and inspection coordination prior to any overburden, screed, tiling or protective layer being installed.
Protection / Handover
Protection boards, drainage cell and screed coordination, then handover documentation issued to the project team.
Detail is everything
The membrane is only as goodas the detail beneath it.
Substrate
Moisture content, laitance, contamination and cracking are assessed and corrected. A membrane can only bond to what is underneath it.
Quality Assurance
Proof before handover.
Condition, moisture and falls recorded before works commence.
Built to the requirements.Documented to prove it.

Systems we work with
System selection depends on substrate, exposure, movement, overburden, drainage, application method and project requirements. The right product on the wrong detail still fails.
Cementitious and liquid-applied membrane systems used across wet areas, balconies and podium decks.
Polyurethane, cementitious and below-ground systems engineered for movement, exposure and hydrostatic load.
High-performance sheet and liquid membranes specified on commercial roofs, terraces and trafficable decks.
Manufacturer names are listed to identify the systems VVS installs. No endorsement, sponsorship or accreditation is implied unless separately stated in writing.
