Dynamic Testing & Pile Testing

Dynamic Testing of Foundation Piles (PDA)

Dynamic testing is a versatile test for pile capacity, performance of the driving system, and pile integrity. It is gaining wide acceptance in North America and overseas, as an alternative to expensive and time-consuming static loading tests. The procedure for this test is also explained in ASTM Standard D4945-00

  • Extremely accurate
  • Fast Data turn over
  • Experience personal
  • Easily performed with completely portable self-contained equipment

Static Loading Tests Foundation Piles

Traditionally, static loading was the most common way of testing pile foundations. There are several accepted procedures to set-up and perform a static loading test, which are explained in detail in ASTM Standard D1143. Recently, another form of static testing, the Osterberg Cell (O-CellTM) testing, is becoming a very popular method for testing drilled shafts.

  • Easy to setup and use
  • Extremely accurate
  • Capable of collecting data at two-second intervals
  • All readings of load and displacement are taken simultaneously
  • Eliminates human errors in reading instruments

Pile Integration Testing (PIT)

This non-destructive testing method is one of the most versatile means of quality assurance when it comes to cast-in-place concrete foundations. It is fast, inexpensive, and completely portable.

  • Cost-effective and fast
  • Detects the extent and location of pile or caisson damage
  • Easily performed with completely portable self-contained equipment
  • Allows the inspection of a large number of piles within a short timeframe

Cross-Hole Sonic Logging (CSL)

This state-of-the-art testing method uses the sonic wave propagation theory to check the material quality and integrity of newly placed drilled shafts, seal footings and slurry or diaphragm walls, and other structures. This method is gaining popularity in the industry for its versatility and reliability.

  • Cost-effective and fast
  • Detects the extent and location of damage
  • Easily performed with completely portable equipment
  • Performed at practically any depth with no loss of accuracy
  • Can be used to check the efficiency of repairs
  • Provides an increased level of confidence in foundations

Geotechnical Engineers

AAtech Scientific was established in 1997 in Ottawa, Canada. AAtech quickly built strong partnerships with leading researchers in geotechnical & foundation engineering with strength in various specialized disciplines in the industry. Having advanced signatory certification for PDA and CAPWAP testing and analysis, AAtech then became the leaders in geotechnical & foundation engineering.
