Geoscan offers both high-strain dynamic load testing and static load testing of installed piles, as well as PDA monitoring of driven piles during installation. Load testing of piles removes some of the inherent uncertainty of a pile’s capacity by measuring the actual in-place capacity of an installed pile. By testing a representative sample of piles on a given project a higher percentage of the predicted strength may be used all the piles, thereby reducing the unit cost for a given capacity of deep foundation units on a site, providing a more efficient, economical foundation system for the owner.
High-Strain Dynamic Load Testing

Dynamic load testing of piles is most often carried out with driven piles but can be applied to any type of deep foundation. An accurate estimate of the deep foundation capacity can be achieved using specialized equipment which can calculate the resistance along a pile shaft as a result of the impact of a dropped mass. In Alberta, piles designed and installed on the basis of estimated soil resistance alone may use 40% of the estimated ultimate capacity, however piles tested using high-strain dynamic testing may use 50% of the ultimate capacity. As a result with some testing you can use fewer piles, saving you money. Geoscan offers interpretation from the only “Master” ranked professional in Canada on the Dynamic Measurement and Analysis Proficiency Test.

Beginning in early 2014, Geoscan will be offering dynamic load testing using our custom designed and fabricated THUMP testing unit. We will then be able to dynamically test all types of piles up to 3000 kN capacity (675 kips) without the need for a crane or pile driver.
Pile Driving Analysis

The measuring equipment used in dynamic load testing can also be used to monitor driven piles during installation. Geoscan uses Pile Dynamics Inc. Pile Driving Analyzers (PDAs) for both driven pile monitoring and high-strain testing.
