Allan Block in Casa De Oro, CA.
Allan Block for Casa De Oro homes, done by licensed San Diego County wall crews. Allan Block is the most widely specified engineered segmental retaining wall system in San Diego County, used on everything from residential hillsides to commercial grading projects. We connect homeowners and property owners with insured local crews that install Allan Block to manufacturer specifications, including the correct batter angle, geogrid reinforcement layers on taller walls, and drainage aggregate behind the face.
Why is allan block different in East County San Diego?
East County clay soils and the wide wet-dry cycle that drives seasonal soil expansion make Allan Block's geogrid reinforcement particularly valuable. Geogrid layers in the fill behind the wall distribute lateral load across a wider soil mass rather than concentrating it against the back of the block face. Crews in El Cajon, Santee, and Spring Valley typically specify geogrid starting at 28 inches of wall height rather than waiting for the manufacturer's minimum threshold.
What's included in allan block in Casa De Oro?
- Excavate base trench and install compacted road-base pad to manufacturer tolerance

Inland East County community with summer highs of 85 to 95 degrees, mild winters, approximately 12 inches of annual rainfall, and fire risk in the surrounding hills.. East County clay soils and the wide wet-dry cycle that drives seasonal soil expansion make Allan Block's geogrid reinforcement particularly valuable.
What makes Allan Block different from standard concrete block?
Allan Block units are designed specifically for segmental retaining walls, with a built-in batter setback on each course and a hollow core that fills with drainage aggregate as the wall goes up. Standard CMU block is set vertically on a concrete footing. Allan Block walls rely on mass, batter, and geogrid for their structural load path rather than a reinforced concrete core, which makes them faster to build and well-suited to residential grading.
When does an Allan Block wall require geogrid reinforcement?
Allan Block's engineering tables specify geogrid at different intervals based on wall height, batter, and surcharge load. In practice, most walls over 28 inches high benefit from at least one geogrid layer, and walls over four feet in San Diego typically require an engineered design that specifies geogrid spacing. Your crew follows the manufacturer tables and any engineered plan requirements.
