Our core business
Sand & aggregates, delivered to your site
We sell the sand we extract with our own dredgers — sand, gravel and all-in aggregate, delivered in Douala and across the Littoral.
Selling sand is our core business. Since 2011, STIS has run its own dredgers in Cameroon — we control the whole chain, from extraction to delivery on your site.
Because we operate our own dredgers, we control the quality and the consistency of supply: no middleman, no supply running out mid-project. The sand is extracted, loaded and delivered wherever you need it.
From dredged sand to gravel and all-in aggregate, we deliver the right materials in the right quantities — backfill, masonry, concrete, foundations — from the individual building a home to the company supplying a major site.
Our dredgers also work for your projects: hydraulic dredging and backfill for land reclamation and site preparation. Tell us about your project — we'll assess feasibility with you.
