French Drains & Lot Regrading in Salt Lake City, UT

French drains and lot regrading are the most common fixes for wet basements, soggy yards and water flowing off the hill behind a house. A French drain is a gravel-filled trench with a perforated pipe that collects groundwater and surface seepage and carries it to an outlet. Regrading reshapes the soil so surface water flows away from the foundation instead of toward it.

Why it matters here

Salt Lake City gets most of its water as snow, roughly 60 inches in an average season, and most of it melts within a few spring weeks. Clay-rich lake soils absorb it slowly, so water lingers against foundations. Homes on the benches also catch runoff from the lots above. In 1983 snowmelt overwhelmed City Creek and turned downtown streets into waterways, an extreme example of what fast melt can do.

Curtain drains on the uphill side

When water comes from up the slope, a curtain drain across the uphill side of the yard intercepts it before it reaches the house. HomeGuide puts curtain drains at $10 to $35 per linear foot, or $1,500 to $8,800 total.

Perimeter drains at the footing

When water is entering the basement through the walls, a deeper drain at footing level, often combined with exterior waterproofing, may be needed. HomeGuide lists deep exterior perimeter drains at $1,200 to $4,500 per side of the house.

Where the water goes

A drain is only as good as its outlet. Options include daylighting to a lower part of the lot, a dry well where soils allow, or a connection the city approves. Clay soils limit how well dry wells work, so we check before recommending one.

Regrading

Many older homes have settled soil and raised flower beds that slope toward the walls. Restoring a fall away from the foundation, and extending downspouts into solid pipe, is often the cheapest effective fix. HomeAdvisor lists yard grading at $400 to $6,500.

Window wells and egress

Basement window wells are a common entry point for water. Regrading around them, adding gravel and connecting the well bottom to a drain often stops leaks without touching the foundation.

Keeping drains working

Fabric around the stone, cleanouts at key points and a free-flowing outlet keep a drain working for years. Silt and roots are the usual enemies.

Fall season installs

We like to finish drainage work before the ground freezes, so the system is tested by fall rain and ready for the spring melt.
