Centre-line Investigations
A centre-line investigation characterises the ground along a proposed route before design and construction — identifying materials, layer strengths and problem areas that drive cost and risk. Getting it right lets you optimise the route and the earthworks.
Letaba Lab is highly experienced in centre-line investigations from 200 m to 1 000 km in length, across roads, rail, pipelines and powerlines. We combine test pits, DCP surveys, GPS positioning and in-situ and laboratory soil testing.
Deliverables include Google Earth maps, GPS coordinates, layer profiles, photographs, DCP results and soil test data — presented in clear, full-colour reports your design team can act on.
