Retaining Walls, Decks and Additions in Whittier
Retaining walls, deck footings and additions in Whittier, starting with a check of drainage, wall condition and how the lot changes level across the yard.
Water gets checked before anything else at a Whittier property: where downspouts empty, where water pools after rain, and whether any existing wall shows cracks, lean or stained weep holes. If the yard changes level, we measure each wall height and look for loose fill behind it. That walk tells us whether a deck, addition or patio can sit on ordinary footings or needs a soils report first.
Walls that hold back a grade change
A new retaining wall is designed for its height and for whatever load sits above it, whether a driveway, a structure or just sloped soil. Reinforced block or poured concrete rests on a footing with a heel extending under the retained earth. Behind it, crushed rock and perforated pipe wrapped in filter fabric carry water to an outlet that empties away from the house. Walls past the exempt height, or any wall carrying a surcharge, need engineering and a permit from the building department serving Whittier.
Decks and additions above a wall
Where a deck or room sits near the top of a wall, its footings are set back far enough or carried deeper so they do not push on the wall below. The engineer may specify drilled piers to reach firm soil past any loose fill. Exposed hardware is galvanized and framing lumber is treated wherever it meets concrete. Projects in Hacienda Heights, La Habra Heights, El Monte, Downey, Rowland Heights and Monterey Park run through the same survey, soils, engineering and inspection sequence.
