"We deal with all materials used within the construction industry"
We can conduct inspection work
Recommend repair techniques
The construction industry continues to use new materials and different combinations of materials along with tried and tested materials. However, poor materials knowledge, poor workmanship and poor quality control can lead to big underlying problems that may not manifest themselves until well after completion of the project. Materials Technology offers solutions throughout the world for construction and fabrication related problems within this industry. On this page you will find just two examples of cases to give a flavour of our work.
Steel I-beams in a multi story car park which suffered cracking between the web & the flange. The cracking is visible in the image showing sections through a beam.
This required repair techniques to be developed for installed beams. Regular examination of the beams in service has confirmed the efficacy of the repairs.
Failure of nodes supporting a roof.
The roof structure is shown below in the photo. Each strut connects through a node. The nodes had been galvanized after welding and were exhibiting cracking in the welds and surrounding parent material. This could have resulted in complete roof collapse.
Investigation was undertaken to determine if the cracks were caused by weld quality, hydrogen or liquid metal embrittlement.
The crack illustrated in the picture below shows the galvanising layer on the top and penetration of zinc into the crack.
