PILE TESTING

BI-DIRECTIONAL STATIC LOADING TEST (BDSLT)

AATech’s Bi-Directional Static Loading Test (BDSLT) is the most innovative static load testing technique in the industry. The accuracy and speed of AATech’s testing method has made bi-directional testing an invaluable tool. Traditionally, BDSLT has been the most trusted means of testing pile foundations axial capacity. AATech engineers have developed automated testing systems and data acquisition software to eliminate human errors and to increase the reliability and accuracy of measurements in load testing.

ADVANTAGES

  • Simultaneous collection of data on load strain and displacement
  • Eliminates the need for reaction-frame and piles
  • Fully pre-assembled bi-directional cell
  • Capable of collecting data at one-second intervals
  • Extremely accurate.

DYNAMIC 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.

ADVANTAGES

  • Extremely reliable
  • Over 20,000 piles tested and counting
  • In-house CAPWAP and WEAP analysis
  • Easily performed with portable self-contained equipment
  • Engineer on-site within 2 business days

STATIC LOAD TESTING 

Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.

ADVANTAGES

  • Highly accurate
  • There is no test load we can’t reach
  • All reading of load and displacements are taken simultaneously

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.

ADVANTAGES

  • Accurately detects the extent and location of damage with a full analysis report
  • 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
  • Over 1,000 piles tested and counting

PILE INTEGRITY TESTING (PIT) 

Our non-destructive testing method is one of the most versatile means of quality assurance when it comes to cast-in-place concrete foundations.

ADVANTAGES

  • Fast and reliable
  • Cost effective
  • Easily performed with portable self-contained equipment
  • Reliable quality-control and depth-investigation tool
  • Engineer on-site within 2 business days

THERMAL INTEGRITY PROFILING (TIP) 

Evaluation of the entire cross-section and the entire length of the deep foundation element measuring heat generated by curing cement to assess the quality of drilled shafts/bored piles, augured cast in place (ACIP)/continuous flight auger (CFA) or drilled displacement piles, slurry walls, barrettes, soil nails, and jet grouted columns.

ADVANTAGES

  • Evaluates concrete quality inside and outside the reinforcing cage
  • Accelerates construction with tests conducted during concrete curing
  • Reveals necking or inclusions, bulges, variations in concrete cover, shape of shaft and cage alignment
  • Thermal Wire® Cables can replace access tubes
