Retaining Wall Contractor for New-Construction Backyards

The builder graded your lot for drainage, not for a usable yard

When a production builder preps a new-home lot, the grading is done to move water off the pad and satisfy the civil plan, not create a flat backyard. That is why so many new-construction homes across Los Angeles, Orange, Ventura, Riverside, and San Bernardino counties come with a slope rising or falling right behind the sliding door, a fence line sitting three or four feet above the patio grade, or a side yard that drops away toward the neighbor. The dirt that slope is made of is usually compacted fill or expansive clay, and clay does not sit still. It swells when it takes on water in winter and shrinks when it dries out in summer, and that seasonal movement is exactly what pushes an unengineered wall over.

A retaining wall solves two problems at once. It holds the graded soil back so it stops creeping onto your patio and pooling water against the foundation, and it carves flat, usable square footage out of a slope you otherwise could not stand on. That is often the difference between a backyard you can put a lawn, a patio, or a pool pad on and one that stays a dirt embankment.

A wall is only as good as the engineering and drainage behind it

Most failed retaining walls in this region fail for one of two reasons: they were never engineered for the height and load they carry, or nothing was done to relieve water pressure behind them. Five Stars Builders engineers every wall to its actual conditions, submits for HOA height and color approval before we build, and installs a real drainage system behind the wall so hydrostatic pressure never gets the chance to build up and tip it forward.
