leaky pipes that occur inside walls are can cause anxiety with any property owner “you may have to open walls or ceilings to repair the pipes and the damage the water has inflicted. But when your leaky pipe is inside the concrete of your foundation or floor, you could face a much more expensive repair. While one fix is to re route water around the problem area with new above-ground pipes, epoxy pipe lining often eliminates the need to tear or dig up your concrete foundation or floor by restoring your pipes while they are still inside the concrete.
Sometimes a slab leak will be obvious. You may be able to spot moist, wet, or damp spots (or stains) on your floor or carpeting. There may be water coming through your foundation “or your foundation may begin to settle. Maybe youve noticed low water pressure. It may be a noticeable (even dramatic) increase in your water bill.
Slab leaks may occur in your houses incoming water pipes or in your outgoing sanitary sewer line. Both of which may have been laid in or under the foundation of the house. Leaks in both lines can cause extensive damage to the foundation. Each has its own set of causes, some are shared. Slab leaks involving the incoming water line can be potentially more destructive because the supply water is under pressure (its coming from the citys water main). It runs through or under the concrete slab, then to the water heater where copper pipes split off and deliver water to all the hot and cold water fixtures in your house.
There are four main causes of slab leaks in a houses incoming water lines. Chemistry is the 1st, either the chemical interaction between copper water pipes or the water running though them (copper pipe is very susceptible to pinhole leaks caused by the chemical composition of your water), or electrolysis from the copper pipe coming into contact with soil. The 2nd is that due to the foundation shifting (because of poor design or installation, or a change in the moisture of the ground) and pull your pipes apart. The 3rd is pressure that is too high (the size of the pipes installed may be too small) will corrode copper pipe. Leaks will also form at points where the pipes bend or change direction. The 4th cause may just be poor workmanship or craftsmanship: inferior plumbing supplies or materials (e.g. soldering, pipes) or a plumber that rushes or inexperienced. It could also be a kinked line (a piece of pipe with an imperfection) or nicked by another (non-plumbing) worker, such as the concrete contractor.
Unlike those in incoming water lines which will continuously leak because of the continuous flow and pressure, slab leaks in sanitary sewer lines only leak when a toilet is flushed, someone takes a shower or bath, or faucet is turned on. There are four main causes of slab leaks in sanitary sewer lines. The first is a crack or break in the cast iron, galvanized steel, or PVC sewer pipes, caused by shifting of the foundation. The second is, in the case of cast iron or galvanized steel pipes, parts of the pipe may be exposed to soil, sand, or gravel which are porous to water -this can lead to rusting. The third cause is the chemicals, solvents, and cleaning solutions that are poured down the drain which interact and corrode the metal pipes. The fourth cause is poor craftsmanship or workmanship, inferior plumbing supplies or materials, or a plumber that rushes or isnt experienced.
If you think have a slab leak, you should get a free estimate from a qualified epoxy pipe lining company. Rather than go through the time-consuming (days or even weeks) and expensive process of either re-routing the affected plumbing altogether, or digging/breaking up your concrete floor or foundation, destroying the flooring you may have covered it with, and buying new replacement pipes, you may be able to save time and money by restoring the pipes you have, right where they are (by connecting epoxy lining equipment to your existing fixtures and valves). A conventional repair will solve your problem right now, but epoxy pipe lining can protect your plumbing system from future slab leaks.
