Why load test your fixings?

​

You may have insufficient data available to determine the resistance of your post-installed anchors, or you may not have enough information about the base material. 

​

In order to verify the installation quality of your post-installed anchors, you may be required to proof test them.

At Elephant we carry out on site testing to determine the maximum load the anchor can withstand (Preliminary or ultimate testing), and to prove the anchors can withstand the required load or to have a record of the installation quality (proof load testing).

 

Preliminary (Ultimate load) testing is carried out to determine the maximum load the fixing can withstand. This involves loading fixings until failure occurs.

 

Proof load testing is used to verify that fixings are sufficient for their required use. This involves applying the maximum design service load plus an additional safety factor.

​

​

We test in accordance with the following standards and guidance:

​

  • BS8539:2012 Code of practice for the selection and installation of post-installed anchors in concrete and masonry

  • CFA guidance note: Procedure for Site Testing Construction Fixings – 2012

  • Shear testing in accordance with BS5080-2:1986 Structural fixings in concrete and masonry – Method for determination of resistance to loading in shear

  • BRE Digest 421 ‘Measuring the compressive strength of masonry materials: the screw pull-out test’
