A retaining wall in Huntington Beach is pushed on by water before it is pushed on by soil. The city is nearly flat, so a wall here holds a step of 2 to 4 feet that a grader or a pool builder left, and dry sand leans on a wall that height gently. Wet sand does not. Once water sits behind the stem the sand becomes a fluid weighing half again as much, and a wall with no way to let it out tips at the top in its first wet winter. So the drain is the wall.
Goldenwest Huntington Beach Concrete was founded in 2017 by Scott Ferreira, who spent 19 years on crews across coastal Orange County first, and he measures every wall himself. The garden walls in the tracts are mostly grouted block on a shallow footing from the 1960s and 1970s, with weep holes and nothing behind them, and the ones that lean have all leaned the same way, off the top after a wet week. Ours put a perforated pipe in washed rock along the heel.
Walls are built to the California Residential Code under a CSLB C-8 concrete license, with liability insurance on every job. A wall over 4 feet from the bottom of the footing, or one with a drive, a pool or a fence on the ground it holds, is drawn by a licensed engineer and permitted through the City's Community Development Department, and we meet the inspector on the day. Every wall carries a written workmanship guarantee against defects in how it was built.
