Drainage Systems
Stormwater drainage, culverts, and flood mitigation infrastructure for sites and roads.
Service Overview
Poor drainage is one of the leading causes of road failure and site flooding across Africa. IvanZ Construction designs and builds drainage systems that protect infrastructure and keep sites operational through the rainy season.
Our drainage work spans open channels, culverts, catch pits, French drains, and integrated site drainage for commercial yards and municipal zones.
We assess catchment areas, flow volumes, and outfall requirements to deliver drainage that works with local terrain rather than against it.
What's included
- Stormwater drainage design
- Culvert and channel construction
