To verify the compliance of the supplied concrete mix, multiple on-site tests should be carried out. CORINTHI provides all required administrative and technical support for conducting the required tests including;

• Fresh concrete sampling (Cubes, cylinders);

• Slump test;

• Air content;

• Fresh concrete temperature;

• Others

CORINTHI is a leading consulting company in evaluation of all types of structural elements and construction materials using  NDT tests and distinctive analysis approaches including;

Schmidt Hammer Test

Schmidt Hammer is a Non-Destructive Test (NDT) that is normally used for evaluation of the existing concrete strength, elastic properties and hardness of concrete by hitting the concrete at a defined energy.

Covermeter Test

The Covermeter test is a fast and accurate test and used for determination of location, orientation and measurements of reinforcement bars in the concrete, and measuring the exact concrete cover using electromagnetic pulse detecting the magnetic field induced in the metal objects. 

Ultrasonic Velocity Test

This survey method is classified as a non-destructive test and used in investigation and evaluation of;

1. The uniformity of concrete;

2. the presence of cracks, honeycombing or voids;

3. changes in properties with time;

4. determination of dynamic physical properties;

5. determination of surface cracks depths;

6. and determination of modulus of elasticity and approximate strength of concrete.

Pavement Deflection Measurement 

Corinthi has distinctive experience in investigation and evaluation of existing roads including the Pavement Deflection Measurement using Benkelman Beam device to determine the modulus of elasticity of pavement layers.

CORINTHI offers various on-site DT tests for all types of construction materials and structural elements including;

Concrete Cores

Concrete cores is a destructive test used to determine on-site concrete conditions when the in-place concrete quality is doubtful and/or when relevant project information and history are not available.

Concrete cores are used to determine the following;

1.       Concrete general conditions;

2.       Voids and honeycombing existence;

3.       Internal cracks existence and its depth;

4.       Concrete compressive strength.

5.    Other mechanical and physical properties.

Asphalt Cores

Asphalt cores is a destructive test used to determine on-site asphalt conditions for quality control, when the in-place asphalt is doubtful, and/or when relevant project information and history are not available.

Asphalt cores are used to determine the following;

1. Asphalt layers thicknesses;
2. Bonding between asphalt layers;
3. Degree of compaction;
4. Cracks/ honeycombing existence and its characteristics;
5. Other mechanical and physical properties.

Test/ Inspection Pits

Test/ Inspection Pits is a destructive test used for inspection and to determine on-site conditions of various structural elements and construction materials when the in-place conditions are doubtful, and/or when relevant project information and history are not available.

Dynamic Cone Penetration (DCP) Test

The DCP test aims to determine, mainly, the California Bearing Ratio (CBR) for pavement layers (Base, Sub-base, Topping, and Embankment layers). Furthermore, this test is also used for determination of mechanical properties of natural ground for design purposes.

Load Test

CORINTHI has a wide-range and rich experience in providing calibration services for all types of batch plants. Calibration services include calibration of batch plant weighing devices which is carried out according to local and international standards.

The Percolation test is an on-site test which aims to determine the infiltration value and permeability of water in different types of natural ground soils and fill. This test is used during the design stage and/or construction stage in special projects such as; ponds, agricultural, etc.
