Inspection and diagnosis of wooden structures

Inspección y diagnóstico de Estructuras de Madera

We perform the inspection and diagnosis of wooden structures. We assess the state of preservation, pathologies, identify wood-borers (rot fungi, woodworm and termites), design treatments, carry out a visual classification, assign resistance class and make structural calculations.

We offer assistance and support to third party technicians in the performance of Technical Building Inspection (ITE).

In all interventions on existing buildings, it is necessary to obtain a starting point for decision-making. Understanding the state of preservation and pathologies in the wooden structure and its load bearing capacity is essential in order to consider all of the necessary preservation and restoration actions.

Our technicians use the most innovative instrumentation to prepare precise reports on pathologies, state of preservation and resistance of existing wooden structures.
