- Destructive Testing methodologies like Petrographic Evaluations, Chloride ion content determination, scanning electron microscopy
Evaluate reserve capacity of structures.
- Performing structural analysis to determine the reserve capacity of the structures.
Evaluation of Infrastructure at a Port Facility on the Gulf Coast, USA; Inspection of individual concrete piles and documenting defects.
Condition assessment and investigation of distress on a tilt wall commercial building.
Forensic Investigation
Forensic Investigation methodologies are used to identify general distress observed in concrete and other construction materials.

- Condition surveys are supported by field and laboratory tests, where necessary
- We identify problems and make appropriate recommendation for repairs
- Competent repair contractors are recommended to client for bidding process.
CONCRETE
- Concrete Cracking
- Surface Distress such as surface scaling, spalling etc.

The sample from Filter A, was found to be strong and durable; that from Filter B was weak. Average compressive strength of the strong sample is 8,440 psi; the weak grout tested at 1,860 psi.
Petrographic analysis and scanning electron microscopy showed stark differences between the two grouts. The cement paste in the strong grout is dense and compact; that from the weak grout is porous.
