Segmental Walls

Segmental block retaining walls in San Diego County

Segmental retaining wall block systems use interlocking concrete units that build structural walls without mortar, making them adaptable to curved layouts, tiered designs, and sites where a traditional poured or CMU wall is impractical. We connect San Diego homeowners and contractors with licensed local crews experienced in Versa-Lok, Keystone, Redi-Rock, and similar segmental systems. The right block for your project depends on wall height, site access, and finish preference.

Also called: block retaining wall, Keystone retaining wall, Versa-Lok retaining wall. Same work, different words.

When do you need segmental retaining walls?

A pool deck, patio, or yard area on a hillside lot needs a structural wall with a clean finished look

A commercial or multi-family grading project needs a block system that meets structural specifications
An older segmental wall is shifting, leaning, or has lost base course embedment and needs replacement

What do homeowners ask about segmental retaining walls?

How do segmental block walls compare to poured concrete for a San Diego hillside?

Segmental block walls are more flexible for curved layouts and are faster to build on sites where a concrete form and pour is impractical. Poured concrete walls are stronger per foot of height and better suited to very tall walls or walls with heavy surcharge loads. For most residential hillside lots in San Diego under six feet high, a properly installed segmental system performs as well as poured concrete at a lower overall cost.

What block systems do crews typically use in San Diego?

Allan Block, Versa-Lok, and Keystone are the most common engineered systems on residential jobs. Redi-Rock and similar large-format units appear on commercial and infrastructure projects. The choice depends on wall height, structural requirements, finish preference, and what the supplying masonry yard stocks locally. Your crew will recommend the right system after reviewing the site.

Where are San Diego segmental retaining wall permit rules published?

The City of San Diego publishes Information Bulletin 220 for retaining walls. Unincorporated county lots use Planning and Development Services retaining wall handouts, including the county PDF that currently ranks for this topic. Those documents describe when a permit and engineering are required. They do not replace a site visit. Your crew confirms which jurisdiction applies to your address before anyone files.
