This digital concrete test hammer, entirely designed and manufactured by Matest with advanced technology, is capable of assessing concrete strength and detecting potential structural issues early on.

This capability enables the planning of preventive maintenance interventions before more severe damage occurs. By identifying areas in need of maintenance, it helps avoid the necessity of carrying out repairs across the entire structure. Additionally, conducting targeted preventive maintenance interventions reduces the amount of waste generated from demolitions and reconstructions.
