Slab leaks often occur when the waterproofing membrane or pipe breaks down. Usually, the cause of slab leaks is the improper installation of sub-slab pipes. The possible causes of such slab leaks are: * Poor quality of pipes used in an underground pipe (silver-coated copper pipes are highly prone to corrosion) * Incorrect application of underground pipe pressure (pipes which are under excessive pressure can break down and leak) * Excessive soil movement, which may occur if the soil is being lifted by heavy rains * Faulty piping system – for example, some older pipes were designed with small holes, or the pipe joints may not be sealed tightly. * Groundwater leakage – groundwater is usually pumped from beneath the surface, but when the pipe becomes too weak, this water may get inside and begin to move around inside the pipe.
Some of the most common causes of slab leaks include: * Poor installation of sub-slab pipes * Incorrect sub-slab pipeline sealant * Poor sub-slab pipeline connection * Incorrect sub-slab pipeline pressure * Incorrect sub-slab pipeline connection – for example, some older pipes were designed with small holes, or the joint may not be sealed tightly. * Faulty piping system – for example, some older pipes were designed with small holes, or the joint may not be sealed tightly.
There are three main steps involved in slab leak repair. The first step is to check and detect any damaged parts of the pipe. If this is found, the pipe is simply inspected for cracks or damage. A damaged pipe may need to be replaced, or repaired, with the help of a qualified technician. It is important to repair a damaged pipe before the damaged part ruptures, otherwise damage will be done to the leak.
After repairs have been made, the second step is to check for leaks. If the leak is already large and deep, it is necessary to dig the leak out and remove it as quickly as possible. Then the damaged part of the pipe needs to be repaired. When the slab or pipe has been repaired, the final step is to seal it backup to the underlying concrete and waterproof it again.
In order to repair a slab leak, you should never try to repair a leak by yourself. This is because it may not only be dangerous but also very expensive!
Professional repair professionals have the experience and the equipment required to repair a lot of pipe problems, including: * Metal detectors for detecting leaks * Cutting tools for cutting and shaping * Pliers for removing damaged pieces of pipe * Flush-able sponges that can clean and clear the pipe of debris * Heat sealers for sealing backup of damaged pipe * Drill presses to enlarge cracks in damaged pipes * Hacksaw to enlarge the damaged area and remove damaged pipes * Cutting torches to widen the affected area The cost of repairs depends on the severity of the damage, the extent of the leak, and the type of pipe being repaired. The more damaged the pipe, the higher the cost of repairs.
If you choose to try to fix the leak yourself, make sure to wear appropriate safety gear such as gloves, eye protection and a mask if the damage to the pipe is large. If the pipe has already reached the end of its pipe, don’t open the valve of the drain until a qualified technician arrives. Don’t try to dig through the pipe until you have been properly trained.
Before calling a professional, have all the details about your pipe repair prepared. You should also ask any questions you might have and ensure that you are able to call for assistance immediately. Most of all, follow all directions given by the professional to the letter!
