Projects - NON-DESTRUCTIVE TESTING OF STRUCTURES

Building condition survey, structural analysis and audit, pile integrity testing and assessment of vulnerable structures

Image 01

Non destructive Testing (NDT) is used to examine condition or quality of a structure without damaging it. We offer the following services using state-of-the-art testing techniques:




Reinforced Cement Concrete (RCC)

- Rebound Hammer tests for assessing the concrete compressive strength.
- Ultrasonic pulse velocity tests for establishing quality of concrete.
- Drilling out concrete cores for laboratory testing to determine compressive strength.
- Tests for determining depth of carbonation in concrete.
- Half-cell potential tests for determining likelihood of corrosion of reinforcement.
- Tests for determining the chloride & sulphate contents in concrete.
- Rebar locator tests for determining details of rebars in various RCC members and for assessing concrete cover.
- Permeability of insitu concrete.
- Pull Out (LOK), Pull Off and Break Off Tests.

CONDITION SURVEY

Mapping defects in buildings, bridges and dams through rapid visual survey to plan NDT locations for effective testing.

We have provided services for a variety of important projects involving reputed organizations. Some of the projects handled include but are not limited to:

Investigation for Slope Stabilization, Crude Oil Project, Mangalore
Stability of Slope for Box Pushing for RUB using Soil Nailing Technique for Northern Railway/S. P. Singla Construction, Delhi (CWG Project)
Slope Stabilisation Work by Soil Nailing Technique - GSVM, Gurgoan		 Slope Stabilisation Work by Soil Nailing Technique- GSVM, L&T, Bhai Veer Singh Marg
Stabilisation of Naintial landslide, Uttarakhand
Slope Stabilisation Work by Soil Nailing Technique Plaza cum VIP Car Park Outside Golden Temple, Amritsar

PILE INTEGRITY TESTING (PIT)

Pile integrity test is performed using a portable, battery powered unit, which requires no backup vehicle or vulnerable cables disrupting normal construction activity. This small strain impulse technique enables the integrity of piles to be established rapidly and economically to enhance confidence in the foundation. About 200 piles per day can be tested with this unit, depending on access and pile head condition.

CROSS HOLE SONIC LOGGING (CHSL)


The Cross Hole Sonic Logger is used to detect defects in concrete structures and in other solid structures such as rock or concrete-rock interfaces. Defects that may be detected using sonic logging include: honeycombing; segregation due to improper concrete placement methods; washout of cement due to groundwater flow; cracks in pile shafts due to shrinkage; inclusion of foreign material causing contamination of concrete; necking and arching of piles due to collapse of side walls during withdrawal of temporary liners.

VIBRATION MONITORING


Monitoring and analysis of vibrations
a) For optimizing hammer parameters for soil compaction
b) At power house sites due to turbo-generators
c) During driving of sheet piles
d) Due to traffic movement over rock mass
e) In abutments due to movement of overhead trolleys For assessing safety of construction due to vibrations imposed by blasting
