| :: High Strain Dynamic Pile Testing |
”Quick, cost saving and reliable. You save time, money and gain quality assurance”
Soil Dynamics (Malaysia) Sdn Bhd is accredited under Skim Akreditasi Makmal Malaysia (Laboratory Accreditation Scheme of Malaysia) to perform high strain dynamic pile testing since 1999. High strain dynamic pile test is perform using Pile Driving Analyzer (PDA) together with strain sensors and accelerometers. PDA is used to verify the mobilised capacity of all types of drilled and driven piles. Testing is conducted in a quick and non-destructive manner, and is in accordance to ASTM D4945-2000.

Dynamic measurements of force and velocity will be collected by the strain sensors and accelerometers attached to the pile. The PDA monitors the strain and acceleration caused by the hammer impact, and processes these signals after each hammer blow during driving or restrike to give immediate visual. The signals are digitised by PDA, results are computed, and the data array of the signals for a blow is stored.
The following PDA results are typically obtained on site:
- Mobilised Static Load Capacity based on CASE method
- Pile Integrity – location and extent of damage
- Driving Stresses – maximum compression / tension forces at pile top / toe
- Hammer Performance – maximum energy transferred to pile

Advantages of Dynamic Pile Testing
- Instant preliminary results on site
- Instant check on pile integrity and location of any damage
- Feedback on maximum tension and compression forces
- Direct measurement of hammer input energy and efficiency
- Cost effective

Static load tests are expensive and time consuming, and therefore are often conducted only on a very small number of piles. With PDA many more piles can be tested at much lower cost and speed. This increases quality assurance and helps to optimize pile driving criteria. PDA results also correlate very well with piles capacities obtained from conventional static load tests and confirm the structural integrity of the pile element. PDA is the answer for projects where static testing is prohibitively expensive or physically impossible. |

Provision of Hammer
We also offer service for provision of full range hammer on site for high strain dynamic pile testing, i.e. 1T, 2T, 5T, 9T, 20T and 30T hammer.
