About Willem Olaf

Our Story

Willem Olaf was founded to close the gap between international geosynthetics manufacturers and the realities of building in Nigeria — long import lead times, inconsistent specification support, and limited local stock for products that engineers need on short notice.

We supply certified geomembranes, geotextiles, geogrids and drainage composites from stock in Lagos, supported by a technical team that understands laterite soils, rainy-season construction windows and the documentation requirements of government infrastructure projects. Our mission is straightforward: give civil engineers, contractors, developers and government agencies the right material, the right data sheet, and the right support, so that drainage, road, water and foundation projects perform as designed for their full service life.

• Local market knowledge — products specified for laterite soils, clay subgrades and the West African rainy season.
• Certified products tested to ISO, ASTM, EN and DIN standards before they leave the warehouse.
• Fast delivery from stock held in Lagos to project sites across Nigeria and the wider region.
• Technical support from specification and quantity take-off through to site installation.
• After-installation guidance to help your team get the design life from every roll.
