Pile Tests

Our service offerings are pile testing and instrumentations for geotechnical and construction engineering.

Main Services: Pile Testing 
We are the world’s leading pile test specialist competently to test all 10 types of pile test methods
(static & dynamic & imaging) as listed below.

Static Test

Static Load Pile Load Test (compression, tension, horizontal)

Static load testing applies load incrementally to a deep-foundation element, while measuring foundation movement. Types of static load tests include axial compression, axial tension and lateral.

Static Test

Bi-Directional Pile Load test (BDPLT), using YJACK

Bi-directional Static Load Test using YJACK static is a steadfast Maintained Load Test option for both large and small diameter piles that is widely used in the market.

Static Test

Pile Instrumentation for Pile Load Test (PIPLT)

PIPLT is to obtain the unit shaft friction and end bearing and utilizes Vibrating Wire Strain Gauges (VWSG) to measure strain at fixed locations and compute the effective transfer of forces to the various depths of the pile.

Dynamic Test

High Strain Pile Load Test (HSPLT)

HSPLT is a method of testing deep foundations to obtain information about their capacity and integrity, and in some cases, to monitor their installation.

Dynamic Test

Low Strain Pile Integrity Test (LSPIT)

LSPIT is a non-destructive pile testing method for integrity assessments of augered cast-in-place piles, drilled shafts or driven concrete or timber piles.

Dynamic Test

Ultra Sonic Pile integrity Test (USPIT)

USPIT or Crosshole Sonic Logging Test is to assess the integrity of deep foundation elements such as newly placed concrete drilled shafts and slurry walls, particularly when drilling below groundwater level.

Imaging Test

Closed Circuit TV (CCTV) PIle Integrity Imaging (TVPII)


Imaging Test

Hole Profiling using Ultra Sonic Imaging (HPUSI)

HPUSI detects measures the internal diameter of the hole for drilled bored piles, caissons, barrettes, diaphragm walls and other concrete structures prior to commencing concrete placement.

Imaging Test

Soil Profiling using Radar Wave Imaging (SPRWI)


Physical Test

Concrete Coring Pile Integrity Test (CCPIT)
