Why is allan block different in South County San Diego?

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.
