CMU Wall Construction

need a wall that don’t rot, don’t lean, and don’t fall over when it rains sideways? CMU walls — that’s concrete masonry units — are the answer. they’re strong, affordable, and built to last a long time.

at JK Concrete Contractor, we build CMU walls all over jacksonville — for homes, yards, businesses, storage spots, whatever you got. these ain’t no drywall dividers. they’re solid block walls filled and reinforced right.

What You Get

🧱 Concrete block walls (any height or length)
🪜 Reinforced cores with rebar + grout fill
🚪 Openings for doors, gates, or windows
🌧️ Waterproof coating (if needed)
🧰 Poured footing + tie-beam for support
🎨 Optional stucco, paint, or texture finish

we ain’t throwin’ up some loose blocks and walkin’ off. this is full-structure work, done clean and level.

CMU Walls We’ve Built

in riverside, built a full 6-foot tall backyard privacy wall for a guy sick of his neighbor’s dog barkin’. poured footers, stacked the blocks tight, filled every few with rebar and grout. added smooth stucco finish and paint to match his house. he calls it “the peace wall.”

did another job in arlington where they needed a wall for a new workshop. needed windows, vents, and pass-throughs. we laid block, reinforced it, and left openings so their HVAC and electricians could do their part. now they got a tough shop wall that’ll outlive the roof.

What’s Included?

✔️ Layout planning and leveling
✔️ Excavation + poured footers
✔️ CMU stacking and alignment
✔️ Rebar, core fill, and tie-beams
✔️ Door/window block-outs (if needed)
