Why Proper Drainage Matters for Your Concrete Foundation

If there's one thing we tell every homeowner in the Salt Lake Valley, it's this: manage water around your foundation. Foundation problems in this area are overwhelmingly caused by water — and drainage is the fix that costs a fraction of what foundation repair costs.

Why Utah Clay Soil Makes Drainage Critical

Salt Lake Valley soil is heavy in clay. Clay expands when it absorbs water and shrinks when it dries. When that clay is under or next to your foundation, the expansion and contraction pushes and pulls the foundation — causing cracking, settling, and movement.

The cycle: rain or irrigation saturates the clay next to the foundation → clay swells and pushes against the foundation wall → dry season → clay shrinks and pulls away → foundation settles into the gap → repeat. Every cycle damages the foundation a little more.

Surface Drainage

The first line of defense: grade the ground so water runs away from the foundation. Downspouts should discharge well away from the house. Concrete around the foundation (patios, walkways, driveway approaches) should slope away from the walls.

Subsurface Drainage

In some cases, surface drainage isn't enough. A subsurface drainage system (French drain or footing drain) collects water before it reaches the foundation and channels it away. We assess whether this is needed during the walk-through.

How We Plan Drainage

Every concrete pour we do — driveway, patio, flatwork, foundation — includes drainage planning. We grade the slab and surrounding area to move water away from the structure. This isn't an add-on; it's part of doing the job right.

If you're planning any concrete work near your foundation, we'll evaluate the drainage situation during the walk-through and tell you what we see. See our foundations service page for more.
