Structural investigations and Materials testing

Non Destructive testing of structures, we have NDT equipment’s; Schmidt hammer, Permeability tester, Rebar locator, Electromagnetic Ferrouscan, Resistivity meter and Ultrasonic Measurement instrument.

Destructive testing of structures, we have core drilling equipment.

Fire investigations

We carry out fire investigations and assessment of fire damage to structures by undertaking various tests namely;

Profile Tests; Permeability Test, Resistivity test, corrosion analysis and Carbonation test to determine the chemical changes in concrete for burnt buildings

Non Destructive Tests to include; Schmidt  Hammer test, Electromagnetic Ferrouscan Test, Ultrasonic Pulse Velocity testing, Percussion Sounding and Visual Inspections to determine the various properties and condition of concrete for burnt buildings

Destructive Tests to include; core compressive strength test, Pull Out Test, Pull Off test and concrete chemical analysis to determine the various properties of concrete for burnt buildings.

Steel Testing

Some of the tests we carry out on steel structures;

  • Corrosion analysis on steel structures
  • Rebound hardness test on the steel elements
  • Thickness Test on the steel elements

Geotechnical Investigations.

We carry out Geotechnical investigations and soil testing that entail:

Deep Boring/Rigging

Set up of Rigs for the recovery of rock and soil samples.

Standard Penetration Testing

An in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of the soil stratum. 

Cone Penetrometer Testing

The cone penetration test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy

Electrical Resistivity Testing

Electrical Resistivity Tomography (ERT) is used for electrical characterization of subsurface soil.

Plate load Bearing Test

The Plate Bearing Test (or Plate Loading Test) is an in-situ site investigation field test used for determining the ultimate bearing capacity of the ground and the likely settlement under a given load.
