Soil Analysis
Soil analysis & soil conditioning testing
In order to undertake any geotechnical works such as drilling, a comprehensive soil report is available from accredited geotechnical companies. Such reports identify parameters as wet and dry density, grain size distribution, permeability, Atterberg limits (when clay is present), mineralogical analysis (where relevant). Soil analyses and soil conditioning testing is especially crucial for projects with high sensitivity to soil behavior. Using internal and external resources Niva Solutions is able to run required soil analysis and propose Drilling and lubrication fluid solution and soil conditioning agents to the clients.
Drilling and lubrication fluids
We are able to run soil analyses for a variety of applications, such as drilling in deep foundations, Tunneling with Slurry Shield, Variable Density machines, Pipe Jacking, Direct Pipe Method and HDD.
Products for soil conditioning
There is a continuous demand for the conditioning of soil with the use of Earth Pressure Balance Machines (EPBM). During the EPBM technique soil conditioning products are generally injected ahead of the cutterhead and often also into the working chamber and screw conveyor. Choosing the right soil conditioning solution and adapting it to the encountered soil and ground water conditions, will have immediate effect on a variety of soil properties:
• reducing stickiness of plastic clays.
• adjusting soil consistency
• reducing the soil permeability to minimize water ingress.
