Insitu Testing

The interest towards in-situ (in place) testing, using methods which are either non-destructive (NDT) or cause only very limited damage, is growing locally in the construction industry. As their advantage is early warning of suspect strength, as well as the detection of defects such as inadequate cover, honeycombing, high surface permeability, cavity, or use of incorrect materials which may lead to long-term durability problems.

The process of testing, investigation and evaluation depends mainly on the classical in-situ non-destructive testing of concrete and reinforced concrete. In addition, rapid in-situ testing of drilled concrete cores or dust are also being performed.

The following tests are carried out by our highly qualified technicians and engineers:

Dust Extraction and Analysis

Chemical Analysis of dust samples is considered an important method to detect the presence of chloride ions, which mainly causes corrosion in R.C. structures.

Load Test

Load testing is performed to determine the concrete structure’s behavior under both normal and anticipated peak load conditions.

Rebound (Schmidt) Hammer

This test is carried out for the purpose of estimating the compressive strength of the fresh concrete specimens.

Core Extraction and Testing

Extracted concrete cores can be beneficial towards the assessment of R.C. structures. Tests which can be performed on cores includes Estimated Compressive Strength, Depth of Carbonation and Chemical Analysis.

Electrical Resistivity measurement

This test method measures the electrical resistivity of water-saturated concrete and provides an indication of its permeability.

Pile Integrity Testing (PIT)

PIT is one of the methods for assessing the condition of piles or shafts. The test works well in concrete foundations that are not excessively slender. Usually the method is applied to recently constructed piles that are not yet connected to a structure. However, this method is also used to test the integrity and to determine the length of embedded piles.

Reinforcing bar Pull-out test

This test method determines the bond of anchored bars to the existing concrete.

Patch Repair Pull-off test

This test method is performed to verify the bond between the repair material (adhesive-applied composite materials) and the parent concrete.

Both pull-out & pull-off tests are considered two of the most significant test works for the Quality Assurance process undertaken by the contractor to insure success of the executed repairs.

Depth of Carbonation

Detecting the depth of carbonation in any R.C structure suffering from corrosion, is an important diagnosing tool in the assessment study. Carbonation alongside chloride penetration leads directly to corrosion deterioration of the R.C structure.

Half-Cell Potential

The measurement of half-cell potential at the surface of concrete is one common and standard method of estimating the degree of corrosion in reinforced concrete.

Rebar Cover Thickness Measurements

Assessing the Rebar cover is a key factor in Reinforced Concrete structures, since it is one of the protective measures against corrosion in almost all R.C . design codes.

Ultrasonic Pulse Velocity Test (UPV)

This test is done to assess the quality of concrete by ultrasonic pulse velocity method.
