Site Investigations

CSL’s team of geotechnical engineers have the capability to work with industry professionals and clients to complete accurate and valuable geotechnical investigations. CSL has the capability to help with various site investigations for various needs of the client.

CSL has recently acquired new CPT (Cone Penetration Test) equipment from A.P. van den Berg in the Netherlands, state-of-the-art, developed over 50 years, proven best in the world.

This equipment is ideal for MINING – tailings dam and surrounding mine areas, TRANSPORTATION – major highway and roadway, HYROPOWER DAMS – upstream and downstream and Construction –foundations, where soil is exposed to high and varying forces and additional parameters of stability analysis should often be measured. Determination of shear strength is commonly used to define soil Stability.

Factual/Design Reporting

The geotechnical engineers at CSL have the capability to complete various types of factual and design reports to suit a client’s needs. Importantly, CSL’s team of engineers have been fully trained and are ready to deploy CPT equipment on-site, provide testing services, high quality data acquisition, accurate reliable data interpretation and report results. Services are cost effective, efficient, and accurate results. Ultimately saving project cost, reducing risk of failure, and improving safety.

 

 

Field Fit Engineering Services

CSL’s team understands that difficulties may arise during construction and that these difficulties may require changes to be made. CSL has the capability to work with clients on field fit engineering to allow projects to be completed on time. CSL is just as comfortable on site working with clients as they are in an office setting. CSL has the ability to come to various job sites and complete inspection services.

 

 

Cone Penetration Testing (CPT)

CSL delivers industry-leading Cone Penetration Testing (CPTu) using state-of-the-art electronic piezocone penetrometer equipment from A.P. van den Berg. This advanced in-situ method provides standard CPTu measurements: tip resistance, sleeve friction and dynamic pore water pressure continuously during penetration for comprehensive, high-quality subsurface characterization.

Seismic Cone Penetration Testing (SCPTu)

CSL offers single and dual seismic modules for the collection of seismic wave data and calculation of shear (Vs) wave and compressional (Vp) wave velocities during the cone penetration test.

A normally loaded beam is struck horizontally on each side to generate polarized shear waves at regular depth intervals. A vertical impact on the beam is conducted to generate compression waves.

Electronic Vane Shear Testing

CSL offers high-precision Electronic Vane Shear Testing using the advanced A.P. van den Berg IVane system. This downhole electronic method provides accurate in-situ undrained shear strength measurements, eliminating rod torque effects for exceptional accuracy. CSL maintains two types of electronic vanes:

  1. Slow speed vane: Minimum rotation speed during shearing: 0.1°/s and maximum rotation speed during remoulding: 6 °/s and
  2. High Speed Vane (Fast Vane): Minimum rotation speed during shearing: 1°/s and maximum rotation speed during remoulding: 60 °/s
