Data to help you plan against risk

The d-Rebar has the potential to predict the risk of catastrophic structural failure. In fact, the d-Rebar data can enhance many aspects of engineering design. It measures the strain and load along rigid bolts, and helps to assess steel rupture. 

 

The d-Rebar can be used with various rebars. this includes threaded bolts and a variety of other steel bars used in civil, mining as well as construction projects. 

 

The d-Rebar has been specifically designed to be installed using a rockdrill, and spun in epoxy resin using a rock drill. It may be necessary to modify an installation dolly to accept the head of the instrument.
