Just as you need tailored and expert waterproofing for flat roofs, balconies or basements, lift pit waterproofing needs to be done right first time – both to protect your property and avoid costly remediation.
Danrae Group leads in lift pit waterproofing, so here’s what you need to think about to ensure your waterproofing is sound – and to avoid potential future issues such as leaks, concrete spalling and concrete cancer.
A lift pit is an integral part of a structure and a key point for water ingress if you don’t have high-quality waterproofing in place. Lift pits extend below ground level and, just like a basement, they are damp and vulnerable to water seepage from the surrounding earth. Water will tend to seep in through cracks and rise until it reaches the level of the natural water table.
Water ingress tends to occur more often in older buildings where structural components have deteriorated and cracks in walls and floors may have accumulated over the years, sometimes the result of shifting building foundations. Quite often, our team also sees leaks in lift pits after storms or prolonged rain.
The problems stem back to two main issues – ineffective or poor quality waterproofing and a lack of ongoing preventative maintenance, essential to pick up small problems before they escalate.
Lift pits are not in plain sight, so once you have an issue, you might easily miss it unless you schedule regular checks.
Water entering a lift pit can cause havoc to the lift mechanism, resulting in frequent breakdowns or a complete failure, and it can lead to increased damp and mould through your building, a serious health and safety issue.
At Danrae Group, we’ve been providing first-class waterproofing for strata, construction, civil, commercial and government projects for decades. Our remediation for lift pits tends to be a little more involved than for an area such as a flat roof, primarily due to the difficulty of access.
Thorough remediation includes site clean-up, existing membrane removal, surface preparation, membrane installation and any repair or rebuild work – and that can be costly. Add to that the inconvenience of having an inoperational lift, and it makes sense to stay on top of any waterproofing issues – to catch and rectify them at the first possible stage.
Effective waterproofing needs an effective solution design and expert installation. At Danrae Group, our team is trained and certified to work with every type of membrane and every brand.
For lift pits, we would generally apply a hydrostatic membrane to the interior of the lift shaft, but we make sure every solution design perfectly fits your type of property, building usage and location.
If we do find anything that needs a larger fix, we’ll issue a full diagnostic report with recommendations.
