STIS was born of one conviction: Cameroon can build better. When sand was still gathered by hand, we were among the first to mechanize dredging — and to deliver not just 'sand', but the exact grade each project demands.
That standard took us onto major projects: we've supplied leading construction firms — Razel, Yenigün, Sogea-Satom — and taken part in large public works, notably at Kribi. But the heart of our business remains the local builders we work with every day, from individuals to companies.
As we grew, we integrated the whole chain: our own sand quarry, our dredging fleet, our equipment yard and our engineering office. Around it, businesses that extend our trade — equipment rental, sourcing and import from Europe and China. End to end, one accountable partner.
