With long-standing experience in commercial and residential strata waterproofing, Danrae Group has seen every sort of waterproofing issue.
While poor quality waterproofing is a major contributor to strata defects, there are several common problem areas that if neglected will likely lead to water ingress, affecting your tenants and your property.
Residential and commercial strata property managers are responsible for maintaining the strata building and ensuring the safety of tenants, so it’s very important to have a comprehensive waterproofing solution.
Here are five common problem areas in commercial and residential strata – and Danrae Group’s five-step strata waterproofing solution.
Flat roofs can’t rely on the natural slant of a sloped roof to remove water, so it’s imperative to have a comprehensive solution design that includes adequate drainage. Without it, water is likely to pool on your roof after heavy rain or storms.
Ongoing pooling can damage your waterproofing membrane, and with nowhere to go but down, water will seep into the ceiling cavity through tiny cracks, and eventually into the apartments or offices below.
Other potential problems impacting roof waterproofing include poor quality membrane installation, clogged drains, crocodiling or blistering on the surface or flashing failures due to incorrect priming or installation. Extreme climate conditions may also hasten general wear and tear on your waterproofing membrane.
If undetected and untreated, water ingress from your rooftop will likely cause issues in the apartments or offices beneath, including mould, efflorescence and concrete spalling.
Balconies are exposed to the climate, and without quality waterproofing can be a prime channel for leaks. Your waterproofing solution should allow for adequate flow away from the building façade, with suitably sized drains and the correct number of drain outlets.
It’s also very important to choose the right waterproofing membrane for the environment
suitable substrate layers and coatings plus careful remediation to ensure tiles or other layers above the membrane are watertight.
Water that seeps into walls from balconies may not be immediately visible, but can eventually manifest as mould, flaking paint, cracks or crumbling plaster. If left untreated, this can result in efflorescence, concrete spalling and concrete cancer.
