Activity 8
Civil Engineering
Roads, structures and pipelines designed, inspected and accepted in accordance with good engineering practice.
ForMines, State, municipalities, funders, industry
A cut haul road, a failed embankment or a ruptured pipeline brings an entire operation to a halt. Inspection always costs less than rework.

Our resources
How we do it
Roads, streets and mine haul roads
Earthworks, pavement layers, asphalt, drainage: project management, site inspection and supervision, in Central Africa as in Canada.
Bridges and engineering structures
Bridges, box culverts, culverts, retaining walls: from design to concrete testing.
Water and dams
Retention ponds, reservoirs, networks, water points, hydraulic structures: a site's water is designed from the outset.
Pipelines, pumping and water networks
With Diamond Spectrum, we install, repair and maintain pipelines for a mine or a city: water, sanitation, pulp. Camera inspection, cleaning, trenchless installation, relining of existing pipes, abrasion-resistant linings, pit dewatering, pumps and water boreholes.
- Debswana, Orapa and Letlhakane: lining of clarified water pipelines, anti-abrasion tests on slurry pipeline
- Water Utilities Corporation, Gaborone: diagnosis and rehabilitation of sewerage networks
Technical data sheetDiamond Spectrum, Botswana
- Trenchless installation, CIPP and SIPP lining
- Drinking water and sanitation networks: repair, installation, maintenance
- Dewatering: pumps and pipelines, installation and routing
- Boreholes: installation and maintenance
Buildings, platforms and rail
Industrial halls, public buildings, markets, logistics platforms and railways.
Geotechnics and control
Soils, aggregates, concrete, surveying and setting out: our tests verify what is built, at the Yaoundé laboratory and on site.
