Resistograph Testing

Metro Testing + Engineering has experience and knowledge in specialized timber testing and analysis.  Using a specialized Resistograph drill, our team can detect small pockets of low density wood at depth by drilling a small (1/16”) drill into the wood while recording the resistance to drilling. 

The test is a simple and practical approach to measuring timber members and the drill bit is small enough to not impact the integrity of the timber member. The resistance is plotted on a graph paper which can be used to estimate section loss and the 16 inch drill bit depth is an excellent tool in determining the soundness of the timber member.
