How do you stop water seeping under a slab floor?

If you’ve had a professional successfully identify a slab leak with special equipment or managed to recognize a leak in your concrete foundation on your own, here’s what you can do to handle the issue:

Fill the cracks

No matter how small the cracks are, they can still inflict enormous damage on your house. In order to seal them, you will need a concrete patching compound you can find in hardware and home improvement stores. Apply the compound on a clean crack with a trowel or a putty knife and let it dry until it forms a waterproof seal.

Support joints

Any joints in your concrete floor also invite water to seep in, and the best way to stop water here is to seal them up with exterior-grade caulk. Seal up the joints between the floor and the walls, as well as any expansion joints that were installed in your concrete floor slab. Lastly, seal around any fixtures that penetrate the floor, such as pipes or heaters.

Seal the concrete

Another option is to seal up the porous surface of the concrete with a silicate-based sealant. Spread it over the concrete with a paint roller or a paintbrush and it will penetrate the holes through which water is oozing. The material will reach lime in the concrete, expand, and harden to fill in the surface entirely.

How do you waterproof a slab foundation?

A sure-fire way of averting leaks in the slab is making your concrete foundation waterproof. The most common methods of doing this are:

Installing an interior drain tile system

An interior drain tile system can reduce hydrostatic pressure and stop water from flowing from below and damaging mechanical systems. Placing heating ducts and other mechanicals under your slab can complicate the installation, but the drain tile will take effect as long as it is built in below the level of any HVAC ductwork.

Putting an exterior drain tile system in place

You can also install an exterior drain tile system, along with an exterior waterproofing membrane applied to the frost walls. This will prevent further water penetration through them.

Proper yard drainage and water management

In order to keep your concrete slab dry, you should also make sure to keep your gutters clean and flowing. Additionally, extending downspouts away from the house also goes a long way in preventing slab leaks.
