About Binsalim Geoservices
The team you trust before you build.
A Tanzanian-owned geoscience and engineering firm that owns its rigs, runs its own crews, and delivers the ground data your project is built on, across Zanzibar and the mainland.
Who we are
A Tanzanian geoscience team built on ground‑truth.
Established in 2021 and registered under the Companies Act No. 15 of 2013, Binsalim Geoservices operates from Kiembe Samaki in Zanzibar. We deliver geotechnical investigation, water-well drilling, environmental and survey work, backed by experienced staff and equipment we own.
From the first site walk to the final report, the work stays in our hands, which is how we keep programmes, quality and accountability where they belong.

What makes us different
We investigate the ground. We don't guess at it.
Plenty of firms subcontract the drilling and interpret someone else's data. We don't. We drill, sample and log on site, test through recognised labs, and put our engineers' names on the recommendation. When the ground decides whether your project stands, that ownership is the difference between a guess and an answer.
- Owned rigs and crews, not subcontractors
- Logging and sampling done on site
- Interpreted and signed off by our engineers
