A slab leak is a pipe failing inside or under a concrete floor. In local homes that usually means a supply pipe under the basement floor, a pipe under a slab-on-grade addition or garage, or a heating loop in a heated floor. The water comes up through the concrete, so the damage starts under the carpet or flooring where no one sees it.
Signs of a leak under the floor
- Damp or warm spots on carpet or flooring with no visible source
- A water meter that keeps moving with every fixture off
- A boiler that keeps losing pressure in a heated floor
- A musty smell or lifting tiles near one wall
The EPA WaterSense meter test is the quickest home check.
Drying concrete
Concrete releases water slowly, which makes most slab leaks Class 4 losses. After a plumber repairs or reroutes the pipe, the crew maps moisture across the slab, lifts flooring and pad over the wet area and dries the concrete with LGR or desiccant dehumidifiers and air movers. Walls next to the leak are checked at the base, where water wicks up, and the structural drying logs show when it is done.

Slab and Under-Floor Leak Water Damage questions in Cottage Grove, MN
How long does a slab take to dry after a leak?
Usually four to ten days. Concrete releases water slowly, and a leak that ran for weeks takes longer than one caught early.
Does all the flooring have to come up for a slab leak?
Not always. Carpet and pad over the wet area usually come up; tile and vinyl may stay if readings allow drying through or around them.
Who finds the leak under the floor?
A plumber locates and repairs it, often with acoustic or pressure testing. The restoration team maps the moisture and dries the slab.
Is slab leak damage covered by insurance?
Sudden water damage is often covered, while the plumbing repair and slow leaks may be treated differently. Check your own policy.
Can a radiant heat floor leak?
Yes. A heating loop in the slab can leak, and the sign is often a boiler that keeps losing pressure. A heating contractor repairs the loop.
