Reinforced concrete box sections for high-load road crossings. Built to handle heavy vehicles and peak rainy season water flow.
Concrete or metal pipe for smaller drainage channels. Fast to install and cost-effective for farm tracks and residential roads.
Concrete or steel-reinforced bridges up to ~10 metres. Connecting communities cut off by streams every rainy season.
Inlet and outlet headwalls, wing walls, and channel lining to stop erosion and protect the culvert long-term.
Over 88% of Sierra Leone's roads remain unpaved. Every rainy season, streams cut off communities, destroy road surfaces, and damage property — not because the rain is unusual, but because the drainage was never built.
Done properly, a culvert lasts decades and keeps access open year-round. Skip it, and you're rebuilding the road every year.
We cover Freetown and surrounding districts.
