A poured concrete retaining wall provides superior strength for holding back soil on sloped properties. The installation includes footing excavation, rebar cage assembly, form construction, concrete pouring, waterproofing the back face, installing drainage gravel and a perforated drain pipe, and backfilling. In NorCal's hilly terrain — particularly in Placer, El Dorado, and eastern Sacramento County — retaining walls are frequently needed for lot development and erosion control.

Concrete Retaining Wall en Palo Alto — Preguntas Frecuentes

Do I need a permit for a retaining wall?+

In most NorCal jurisdictions, retaining walls over 4 feet tall (measured from bottom of footing to top of wall) require a building permit and engineered plans.

How long does a concrete retaining wall last?+

A properly built and waterproofed concrete retaining wall can last 50–100 years. Adequate drainage behind the wall is the most critical factor for longevity.

What causes retaining walls to fail?+

Poor drainage is the #1 cause. Water buildup behind the wall creates hydrostatic pressure that can cause cracking, tilting, or collapse. Always install a drainage system.

Poured concrete vs. block retaining wall — which is better?+

Poured concrete is stronger and better for taller walls or heavy soil loads. Block walls are more cost-effective for shorter walls (under 4 feet) and easier for curved designs.
