Slab leaks happen in those areas that are difficult to detect and fix. For example, they can occur underneath a slab basis. Leave the job to professionals who know how to fix a slab leak. They’ll correct it as soon as possible to avoid further damage.
What is a slab leak?
Slab leaks occur when water outflows from the damaged underground pipes beneath the slab of your house. The pipes may crack beneath the home’s slab or plumbing joints and leak, causing the problem. It’s hard to realize that you have a severe plumbing problem emerging because the water lines are underneath the house.
Most common causes of slab leaks
- Soil expansion and contraction
The main thing that triggers the soil to swell and shrink is the changes in ground conditions. It changes from dry to wet. Experts link expansive soil as one of the reasons for frequent slab leaks.
The underground soil movement destroys the water pipes, resulting in water leaks. The leaked water further causes the ground to shift. The process may go on for a while without noticing. By the time you realize it, the extent of the damage may have become so intense.
- Use of unsuitable construction and plumbing materials
Poor pipe installations may cause your slab leaks. If you install pipes with a dent, bent and kinked while constructing, the affected areas continue to weaken. They can burst when exposed to changing water pressure and the ground’s abrasive property.
The plumbing materials you select may contribute to your slab leaks. Older homes usually have galvanized pipes and cast iron, which are durable. However, they easily rust and clog as they grow older.
Newly constructed homes install plastic pipes like chlorinated polyvinyl chloride pipe (CPVC) and polyvinyl chloride (PVC). They are easy to handle and corrosion-resistant.
- Abrasion and other outside pressure
Water pipes are subject to abrasion while in use. They rub against surrounding soil and concrete. The friction makes them crack, causing leaks.
Other outside pressure comes from earthquakes, deep tree roots, underground streams, and soil erosion.
Options for fixing slab leaks
The first step to take when dealing with a slab leak is to contact a specialist. An expert will identify the issue and find the exact leak point through modern equipment like electronic listening tools and water line video inspection.
Here are the repair options after identifying the exact leak location;
- Trenchless slab leak repair
The slab leak repair specialist will carry out minor slab demolition. The aim is to create holes to access the leaking part. The method is non-destructive and less costly. The specialists use Epoxy pipe liners to bond the broken pipe.
If the water lines have severe damages, the specialist can pipe split and insert new pipes larger than the current ones.
- Re-piping or Re-routing
Professionals use the re-piping method when the damage is on many pipes. The plumber installs new pipes to guarantee a leak-free system.
Pipe rerouting involves slabs and wall demolitions. The demolition happens on surfaces with pipes that need replacement. Stay away from your home for a while until the restoration is complete.
- Tunneling beneath the slab
The method helps to avoid the destruction of expensive floor finishes in place. The repair specialists dig work tunnels beneath your house. They are always keen not to tamper with your home’s structural integrity. After completing the repairs, the specialists return all the soil to place.
A slab is a vital part of your home. If it’s leaking, you must ensure that someone does the repairs as soon as possible to minimize further damage. Entrust your work to experienced professionals who will fully address the problem.
