Services
The Rock for Technical Consulting and Laboratories (RTCL) provides Geotechnical services and Materials testing as follows:
Engineering tests
-Engineering tests mainly include tests of soil and aggregates materials (foundation soils, road (embankment – subgrade- aggregate base course), building backfilling).
-Asphalt tests – asphalt mix design – verification.
-Concrete tests – concrete mix design.
-Construction material tests (block, curbstones, tiles).
-Cement – rebar – bitumen – destructive and non-destructive tests – for all kinds of construction materials.
