The Pull Test service is in response to a growing industry requirement to increase the safety and security of fixings and anchors widely used in most construction materials. There has been a major increase in the use of pull out testing, particularly with local authorities who demand that a specific pull out testing programme should be carried out on site by the contractor which is then endorsed by recorded evidence. It is therefore essential that all such site personnel should be thoroughly familiar with the use and understanding of pull out testing equipment. In this respect our operatives have been extensively and robustly trained and are fully certified in pull out test in concrete, which are recognised by local authorities and others in the industry.
The equipment we use is highly regarded from the stable of UK market leader specialist Hydrajaws. We utilise the 2008 Heavy Duty Model tester 145kN Hydrajaws which has been designed to meet the demand for proof load testing of larger construction fixings. A lightweight triangular shape aluminium load spreading bridge has been designed specifically for the model 2008 tester and directs reaction loads away from the fixing, this combined with the tester weighs only 14kg.
We also use the 2000 Deluxe Master Kit, which enables engineers to confirm the holding power of anchors in most construction materials, either for the purpose of establishing safe working loads or to validate the correct installation of existing fixings. The tensile load of up to 25kN is applied to the fixing mechanically and hydraulics are used to register the load through an accurate analogue gauge, making the tester very reliable.
