Waterproofing
Industrial & Commercial Waterproofing
Water is the most patient, persistent threat any industrial or commercial building faces. It finds the smallest gap, works with gravity and time, and shows up as a drip metres from where it actually got in. Effective waterproofing seals the entire building envelope against it — and Sicon Group's waterproofing services protect buildings from leaks and the slow structural decay that follows them.
Where Water Actually Gets In
On a large building, water rarely enters where you see the stain — it travels along steel, timber and concrete before it drips. That's why chasing the drip so often fails. The real entry points are almost always at the details:
- Roof sheeting — side-laps, end-laps, seams and the thousands of fixing points
- Parapet walls and their capping, where the roof meets the wall
- Gutters, valleys and box gutters that overflow or leak at their joints
- Penetrations — pipes, vents, HVAC units, skylights and solar mounts
- Expansion and movement joints that open and close with temperature
- Flashings and wall junctions wherever two surfaces meet
What a Leak Really Costs
A leak is never just water. By the time it reaches the floor it has usually already done its damage out of sight — soaking insulation, corroding steel from behind, and creating the conditions for mould, electrical faults and slippery, unsafe floors. Left long enough, the building's structure quietly decays from the inside.
A stain on the ceiling is a symptom, not the source. The water got in somewhere else and has been travelling — and doing damage — long before it became visible.
Matching the System to the Problem
There's no single waterproofing product that suits every surface. A lasting result comes from specifying the right system for each area:
- Liquid-applied membranes — seamless coatings that flow into every profile and detail; ideal for metal roofs and complex areas
- Torch-on / bituminous membranes — robust sheet systems for flat concrete roofs and slabs
- Reflective coating systems — waterproof and lower internal temperatures at the same time
- Joint and penetration detailing — reinforcement, sealants and flashings at every vulnerable point
- Gutter and box-gutter lining — sealing the drainage that channels the most water
How a Waterproofing Project Runs
Leak Diagnosis & Assessment
We trace the leak to its true source rather than the drip, and assess the condition of the surface beneath. Waterproofing over a failing substrate only hides the problem.
Preparation
The surface is cleaned, repaired and primed so the new system bonds properly. Adhesion is exactly where cheap waterproofing fails first.
Detailing
Every joint, lap, upstand and penetration is reinforced first — these are the points that leak, so they get the most attention before the main membrane goes on.
Membrane Application
The specified system is applied across the area to the correct thickness, sealing it as one continuous, watertight layer.
Inspection & Guarantee
Coverage and adhesion are checked, drainage is confirmed to be working, and the work is handed over with a workmanship guarantee.
"Waterproofing almost never fails in the middle of a flat roof — it fails at the joints, upstands and penetrations. Get the detailing right and the flat areas look after themselves. That's where the real skill, and the real difference, sits."
