Watch out for the indicators that could be a warning signal of water leaking from the drains positioned beneath your home’s slab foundation.
- Moisture or wet spots
- Lumps of concrete may be breaking off from the main slab
- Wet sections may be constantly displaying in the slab, flooring or carpet even during the time when little or no rains are received or mains water leakages
It can critically affect the structure of your building in the long term as water seeps into concrete foundations constantly. To shield you from vital damages, repairs should be carried out sooner rather than later. However, due to the concealed nature of the problem, drain leaks are time and again not spotted until the problem becomes critical.
Moisture from a leaking drain can infuse up into floor coverings, ruining carpets or warping timber boards. Also, it can stir mould and mildew formation inside walls, induce swelling of plaster board, cabinets, and make cracks in floor tiles. In the circumstances where it has been left undetected or unrepaired for prolonged periods, water too can produce decaying in structural timber.
Concrete Cancer Hazard
In concrete slabs, when water comes into contact with the steel, it can cause it to corrode and enlarge, breaking the concrete, bordering the seal and potentially impacting the slab’s structure. This is usually known as concrete cancer and can, at times, create sections breaking away.
Drain Repair Alternatives
The top priority for homeowners to avert ongoing damage to the building’s structure should be to stop concrete cancer and cracking. To find out the leak’s accurate location, a CCTV plumbing examination is helpful for facilitating targeted repairs that need to be performed.
Homeowners can choose from a couple of alternatives:
The first alternative needs cutting a channel in the slab, digging out the pipe and substituting the broken part of the drain pipe. This option demands a certain amount of turmoil. When concrete is being cut, a large volume of dust and clutter is created. To hold the rubble, the vicinity needs to be segmented and shielded with plastic sheeting.
The second alternative needs putting a new lining inside the broken pipe to fasten the leak and create a sturdy, long lasting inner layer, which will avert the waste water from escaping in the future. This option can be performed without cutting the concrete in most of the cases.
Repairing a leaking drain beneath a concrete foundation or driveway using pipe relining has some other benefits too that are mentioned below:
- No need to lift up and spread floorboards, carpet or tiles.
- There is a minimal commotion in your home.
- No need to dig or cut.
- Results are instantaneous. No need to wait for new concrete to be laid and treated.
- Suppose the CCTV drain inspection exposes huge areas of cracking inside the drain, the repair is still as clear-cut.
