A properly built block wall starts with a continuous concrete footing sized to the wall height and soil bearing capacity. We design every wall with vertical rebar at 32–48″ O.C., grouted solid, and horizontal bond-beam reinforcement at every 4 courses, the same engineering required by LA County for walls over 6′.

We handle the full scope: layout, permit drawings where required, footing excavation and pour, block work, cap stone, and cleanup. Wall finishes include split-face CMU, smooth-face CMU, stucco over block, and stone or tile veneer.

What sets our hardscape apart.

01Engineered footings

Continuous concrete footings sized for wall height and soil type, rebar-reinforced and properly cured before any block work starts.

02Full reinforcement

Vertical rebar and horizontal bond beam at code-required intervals. Every cell grouted solid for walls subject to lateral load.

03Drainage behind retaining walls

Gravel backfill, perforated pipe, and weep holes or daylight drain, engineered to handle hydrostatic pressure after rain.

04Finish options

Split-face CMU, smooth block with stucco or plaster coat, natural stone veneer, tile, and coping or cap options to match your landscape palette.

Our Approach

Every block wall we build starts with a geotechnical assessment of the bearing soil and a footing design matched to the wall’s dead load and any surcharge (vehicle traffic, grade change, adjacent slab). No wall goes up on a shallow footing, that’s how walls crack and lean after the first wet season.

For retaining applications, we engineer drainage behind the wall: gravel backfill, perforated pipe, and weep holes or a daylight drain at the base. A retaining wall without drainage is a water dam, we build them right.

How a paver job gets done.

01Layout & Engineering

We stake the wall line, verify setbacks and property boundaries, and size the footing. Permit drawings prepared for walls over 6′ or in hillside zones.

02Footing Excavation & Pour

Footing trench is excavated, rebar cage is set, and concrete is poured and leveled. Vertical rebar stubs left protruding for block threading.

03Block Work & Grouting

Blocks are laid course by course, plumb and level, with horizontal bond beam at required intervals. All cells containing rebar are grouted solid.

04Cap, Finish & Cleanup

Cap block or coping is set; stucco, veneer, or paint finish applied where specified. Site is cleaned, excess material hauled off.

Set in base. Built to last.

Materials & applications.

Concrete masonry walls we design and build, and what's included in each scope.
Privacy & boundary walls
  • 6′ privacy wall, Standard single-wythe CMU wall with footing, full reinforcement, and cap block, requires building permit in most LA jurisdictions.
  • Boundary wall (property line), Wall built to surveyed property line with shared-wall coordination where applicable. We provide as-built documentation.
  • Garden & courtyard walls, Decorative block walls 3’–5′ for garden beds, courtyard definition, and privacy screening at lower heights that may not require a permit.
Retaining walls (block)
  • CMU retaining wall, Concrete masonry retaining wall with footing, rebar, drainage backfill, and weep holes, engineered for walls over 4′ exposed face height.
  • Segmental retaining wall, Interlocking retaining block (Allan Block, Versa-Lok, etc.) for less formal applications where a mortared wall isn’t required.
Finishes & facing
  • Split-face CMU, Factory-textured block face with natural aggregate exposed, durable, attractive, and low-maintenance.
  • Smooth block + stucco, Standard CMU with a two-coat exterior stucco or plaster finish, can be painted or left natural.
  • Stone veneer over block, Natural stone or manufactured stone veneer adhered over the CMU substrate, matches surrounding hardscape.
  • Tile facing, Exterior porcelain or natural stone tile on the block face, matched to pool tile or patio material palette.
Permits & inspections
  • LA County/City permits, Walls over 6′ require a building permit in most LA jurisdictions. We prepare permit drawings and coordinate the inspection schedule.
  • HOA approval, Many communities require HOA approval for perimeter walls. We provide plans and material samples for HOA submissions.
  • Soils report, Required for retaining walls in hillside zones. We coordinate with licensed geotechnical engineers where required by the city.

Block Wall FAQ

Questions Los Angeles Homeowners Ask Us

A retaining wall holds back earth. A freestanding block wall — a property line, privacy or screen wall — holds back nothing, but still has to resist wind and seismic forces acting on a tall, heavy, unsupported plane. Both are built from CMU in Los Angeles and both need a footing sized for the soil, vertical reinforcement tied into that footing, and grouted cells. They are engineered differently, and a wall that does both jobs at once is designed as a retaining wall.

Height limits differ by jurisdiction and by where the wall sits on the lot — front setback areas are typically restricted well below what is allowed in side and rear yards. Separately, structural permit thresholds apply, and for retaining work the height is generally measured from the bottom of the footing rather than finished grade, so a wall that looks modest from the front can exceed the threshold. We confirm both the zoning limit and the structural threshold for the specific parcel before design.

This is worth settling with your neighbour before work starts rather than after. A wall built on the line is generally a shared responsibility, while one built entirely inside your boundary is yours. Where the line is uncertain, a survey costs far less than a dispute. Access matters too: building a wall on the line usually requires working from both sides at some point, and that is a conversation to have early.

Yes, and most of ours are. Stucco in any texture and colour, stone or brick veneer, split-face or precision block left exposed, with caps in concrete, stone or brick. The finish sits on top of the structural cost rather than replacing any of it, so the engineering is the same wall underneath. Pilasters at intervals break up long runs and give a place for lighting or gates.

The symptom usually indicates the cause. Stair-step cracking through the mortar joints often points to footing movement or settlement. Horizontal cracking suggests bending stress beyond capacity. Leaning or rotation at the top on a retaining wall means overturning pressure exceeding design — typically water behind it or a surcharge added later, such as a driveway or parking area above. Efflorescence or damp patches through the face mean drainage is not working, and that is the one to act on early because it precedes the others.

Usually, once past a modest height, and essentially always where the wall retains soil or supports a surcharge. Requirements differ between the City of Los Angeles and separately governed cities such as Glendale, Burbank, Beverly Hills and San Marino, and unincorporated County areas run through the County. We coordinate the permitting and confirm current requirements for your parcel. Estimates and 3D design are free.
