Grim tech provides a complete range of site pile testing and pile condition reporting services to the construction industry. These services include Pile Integrity Testing (PIT); Dynamic Pile Testing (DPT); Cross Hole Sonic Logging (CHSL); pile length measuring and consultancy on the capacity and serviceability of piles.

The Pile Integrity Testing is cost effective and without time consuming services. It gives peace of mind that a pile or shaft is free of major cracks and voids, prior to construction of the superstructure. This integrity test is one of the methods for assessing the condition of piles or shafts. Dynamic load testing is a cost effective alternative to conventional static load testing for a wide variety of pile types and sites. Instead of costly proof-loading with kentledge or anchor piles, the technique uses a heavy falling weight such as a piling hammer to impart a short duration impact to the pile head, whilst monitoring the pile response using temporarily attached transducers. Cross Hole Sonic Logging is used to detect and defects in concrete structures and in other solid structures such as rock or concrete-rock interfaces.

Pile Integrity Tester’ (PIT)

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.
