Our Clientele

Pile Integrity Tester' (PIT) For Low Strain Integrity Testing

PIT performs Low Strain integrity testing, also called Sonic Echo or Pulse Ecno Testing. The PIT may be used for auger cast-in-place (CFA) piles, drilled shafts, driven concrete piles, concrete filled pipes and timber piles. It detects potentially dangerous defects such as major cracks, necking, soil inclusions or voids and, in some situations, can determine unknown lengths of piles that support existing bridges or towers.

The PIT test consists of attaching an accelerometer to the top or side of the foundation to be tested. The accelerometer acquires data resulting from the impact of a small hand held hammer (instrumented or not). If a defect is present along the shaft, its size and location can be estimated by analyzing the propagation and reflection of the wave induced on the foundation by the ammer impact. It is also possible to estimate the depth of the pile toe.

Grim Tech is a leading Group of experts, Qualified and highly experienced engineers in the field of Non–Destructive and Destructive Testing comprising of RCC structures, Piles, and have best track record of last forty years.

Design and. Execution RCC Long Percussion bored piles, under reamed, compact piles, steel sheet piles, soil investigation and soil stabilization is our profession and serve all the prestigious clients ,eg, Reliance, Essar, Birlas, Adani Port, Rama News prints, Shapoorji Pallonji, L&T/ECC,GEB, ABB Alsthom of France, Samsung, Daelim, Hyundai of Korea, ,Telecom, NTPC, ONGC,PWD,Central PWD and Central Building Research Institute, Roorkee.

Non–Destructive and Destructive Testing (NDT) Technology is recognized Nationally and Inter-Nationally. Any High rise, podium tower, chimney, cooling tower, over head tank. Tall or important Structure need to be checked periodically, during and after construction, for their assigned design strength as is in their design concept.

Presently, we conduct static load test on piles in compression - up to 2500T , lateral- up to 200T and pull out up to 900T in any mode(Static, Cyclic, Vibratory, Bi- Drectional Loadig etc. Dynamic Pile load Test as furnished in IS 2911 Part I , Pile integrity Test.

We also do NDT using Rebound Hammer” (sclerometro C 181 N”) to estimate the strength of R.C.C. Beam, Column etc. for general classification of Concrete as per I.S. Code 13311(Part2):1992. Secondly using ultrasonic concrete tester model-4600 for detection of cracks, uniformity of R.C.C. Beam, column etc.as per I.S. Code 13311(Part1):1992. We observe Vibration using electronic vibration meter, caused by machines which may be harmful to existing or nearby structures. We may collect in-situ concrete RCC- CORE samples Using Diamond core cutter and do checking by crushing using conventional methods....
