What are the signs of a slab leak and how can it be repaired?

If you've got a leak in a water line beneath concrete flooring, then you're dealing with a slab leak. Such leaks can lead to major trouble, and may even cause your foundation to sink. This makes it very important that slab leaks are fixed as soon as possible. When you first notice an indication of a slab leak, you'll want to call in an experienced plumber who specializes in this type of repair. Here's a look at common slab leak symptoms and repair methods.

Signs of a slab leak:

Sound of Running Water

A classic sign of a slab leak is that your water should be off but you can still hear water running beneath your house. Though you might not see any physical evidence of a leak, it could still be putting your home in structural peril.

Damp Floor

As the leak continues to build, it may run out of room below your home and begin approaching the surface. When this occurs, you may notice that there are damp spots on your floor.

Cracks in Floor or Walls

When a slab leak goes unnoticed for an extended period of time, it can worsen to the point that it causes structural damage such as cracks in flooring or walls.

Increased Water Bills

If you're sure you haven't been using more water but your bill has significantly increased, then an under-the-radar slab leak could be to blame.

Slab Leak Repair Methods:

Spot Repairs

When the leak is limited to one location, modern plumbing techniques allow spot repairs to be completed. Spot repairs are often an option with newer plumbing systems.


If the system is leaking extensively, then it may make the most sense to replace it entirely. With very old plumbing systems, this is more likely to be the case.
