Concrete works we carry out in Accra
Strip Foundations
Reinforced concrete strip foundations to structural engineer's specification. 42.5N cement as standard. Correct depth confirmed by soil investigation.
Raft Foundations
Required for waterlogged or variable soil — Kasoa, Spintex wetland edge, low-lying Tema plots. Reinforced concrete raft to structural drawings.
Ground Floor Slab
150mm reinforced concrete slab on hardcore. Includes DPC and anti-termite treatment as standard. Minimum 21-day cure before loading.
Suspended Slab
First and upper floor slabs. Formwork, reinforcement to structural drawings, concrete pour, minimum 21-day cure before striking formwork.
Columns and Beams
Reinforced concrete columns and beams. Steel bending and fixing to structural engineer's bar schedule. Concrete placed and vibrated correctly.
Driveways and Paths
150mm reinforced concrete driveway slabs, external walkways, and hardstanding areas.

Concrete Contractors Accra questions answered
How much does concrete work cost in Accra?
Concrete slab (150mm RC) costs GHS 380–600 per m² installed in 2026. A ground floor slab for a 3-bedroom house (110–140m²) typically costs GHS 42,000–84,000. Foundation concrete for a strip foundation: GHS 38,000–65,000. Always specify 42.5N cement for structural concrete.
What concrete mix is used for house foundations in Ghana?
Structural concrete in Ghana should use 42.5N Portland cement (not 32.5N), clean river sand, 3/4" crushed granite chippings, and clean water. A typical structural mix is 1:2:4 (cement:sand:aggregate) giving approximately 25MPa strength at 28 days. Never substitute 32.5N cement for structural elements.
How long does concrete need to cure before building on it?
Structural concrete needs a minimum of 21 days to cure before formwork is struck or significant load is applied. Rushing this process weakens the final structural capacity, regardless of how solid it appears on the surface.
Can concrete work start immediately, or do I need a soil test first?
For foundation concrete, a soil investigation should be completed first — it determines the correct foundation type and depth. Skipping this step is one of the most expensive mistakes in Ghana construction.
