Start with the problem

The right waterproofing system depends on where the water is getting in.

01

Roof leaks

Leaks through concrete slabs, metal roofs, pitched roofs, valleys, ridges or previous repairs.

Find the leak source →
02

Balconies & slabs

Waterproofing for exposed slabs, balconies, planters and water-retaining structures.

See waterproofing systems →
03

High-rise access

Waterproofing, painting, inspections, cleaning and repairs where scaffolding is impractical.

Explore rope access →
04

Preventive care

Scheduled inspections and re-coating before UV exposure and seasonal wear become major failures.

Not every leak needs the same product

Diagnose first. Specify second.

Rainier Waterproofing’s current service scope includes 4 mm torch-on, polyurethane, acrylic, liquid plastic, cementitious and bitumen-based liquid systems. The demo makes the selection process clearer instead of presenting waterproofing as one generic coating.

1. Understand the substrate

Concrete, metal, tiles, plaster, gutters and joints behave differently and need different detailing.

2. Identify movement & water paths

Cracks, flashings, penetrations, box gutters, parapets and expansion joints often matter more than the visible stain.

3. Choose the system

Specify the membrane/coating around exposure, access, traffic and the exact construction detail.

Since 2001

Long-term waterproofing is a maintenance discipline.

Rainier publishes more than 20 years of experience, recommends full inspections every two years, and offers scheduled maintenance including visual checks, re-coating and minor repairs.

UV & weather

Sun, heat, cold and rain gradually age exposed waterproofing systems.

Movement

Buildings expand, contract and move. Joints and junctions need ongoing attention.

Drainage

Blocked outlets and standing water can turn small defects into major leak paths.

Early repairs

Small defects are usually easier to solve before they damage ceilings, finishes or structure.

High-access capability

When ladders stop, the work doesn’t.

Rainier’s rope-access team handles inspections, waterproofing, painting, repairs and window cleaning at height using IRATA-compliant techniques, with less dependence on scaffolding or boom lifts.
