Borrow Pits Investigation
noun · materials sourcing — The prospecting of borrow pits to establish whether suitable construction material is available, and in what quantity.
We conduct borrow pit prospections to determine the suitability and availability of materials for the construction of roads, railways, platforms, beddings and related works.
Prospecting of potential borrow pit sites
Determining the suitability of materials for construction
Determining the availability of materials
Materials for roads, railways, platforms and beddings
noun · in-situ assessment — A survey along the centreline of an existing or proposed route to characterise the materials already in place.
We conduct centerline surveys to determine the geotechnical characteristics of the in-situ materials for the purpose of design for the upgrading or rehabilitation of roads, railways and runways.
noun · ground engineering — The study of soil and rock beneath a site to understand how the ground will behave under a structure.
We carry out in situ geotechnical tests to identify the nature, layer structure and characteristics of the soil, and geotechnical studies concerning stability, deformation and water flow in and around structures in contact with the ground. We also advise on the quality and bearing capacity of the soil and on foundation techniques.
Profiling of soil strata to record the vertical succession of different layers
Determining primary and secondary consolidation due to loading
Determining stress and strain of the soil mass
Determination of slope stability of soil
Identification of possible problem soils
Determination of shear strength of soil
Identification of problem minerals, and other related services
noun · civil engineering laboratory — Controlled laboratory tests on construction materials to determine their geotechnical characteristics.
We carry out geotechnical laboratory tests on soil, gravel, concrete, bitumen, aggregates, water and related samples to determine the geotechnical characteristics. Testing follows the quality control system outlined by SANAS, TMH, SABS, ASTM and other prescribed standards.
noun · construction quality control — Routine on-site testing during construction to confirm that materials and workmanship meet the design and specification.
We provide site laboratories for process and acceptance control by performing routine testing on materials used for roads, railway and runway construction to ensure that design and standard specifications are adhered to.
