Get Waterproofing QuotesWhat Affects the Quote
- Area and condition. Large areas cost less per m², but stripping old systems adds cost.
- System specification. Torch-on, liquid, PU and trafficable systems are priced differently.
- Access and safety. Height, edge protection and safety files add cost.
- Phasing. Working around occupants, after hours or in phases takes longer.
- Guarantee terms. Manufacturer-backed guarantees can require approved applicators and inspections.
How Commercial Jobs Normally Run
- Site inspection. The contractor surveys the roof or deck, drainage and previous repairs, often with core samples.
- Specification. A written scope sets the system, details and guarantee terms so quotes can be compared.
- Safety and approvals. Safety files, fall protection and hot works permits are agreed before work starts.
- Phased work. Sections are done in order to keep the building watertight and occupied.
- Handover. Final inspection, guarantee documents and a maintenance schedule.
Disruption and Access
- Occupants. Noise, smells from torching or solvents, and roof access closures.
- Parking decks. Bays closed in phases while coatings cure.
- Weather. Work stops in rain, so allow for delays.
Questions to Ask Waterproofing Contractors
- Specification. Is the system specified in writing, with detail drawings for outlets and joints?
- Guarantee. Who gives the guarantee, the contractor or the manufacturer, and what conditions apply?
- Compliance. Can you provide a safety file, insurance and references for similar buildings?
- Maintenance. What inspections are needed to keep the guarantee valid?
Commercial Waterproofing FAQs
Should a body corporate get several quotes?
Yes. A written specification lets trustees compare like with like, not just the price.
Can work be done while the building is occupied?
Usually, with phasing and agreed working hours. Torching and solvent systems may need extra planning.
How long do commercial systems last?
It depends on the system, exposure and maintenance. Ask each contractor for the expected life and guarantee period in writing.
Do we need an engineer?
For structural cracks, parking decks or major movement joints, an engineer or consultant may be needed to specify the work.
