The vibrations resulting from explosions and construction sites may jeopardize the integrity of structures.
The Laboratory is accredited by IPAC, according to EN ISO / IEC 17025
Measuring vibrations from explosions and construction sites NP 2074
Mining and geotechnical activities that induce dynamic stresses on the land, namely: the dismantling of rock masses with use of explosive substances, pile driving, dynamic compression of grounds, among others, originate impulsive stress and subsequent vibrations in nearby structures, which, in consequence, may be damaged. These can be classified as severe (significant weakening of its structural capacity), moderate (affectation interior and exterior coatings) or thresholds (cosmetic damage that boil down to opening cracks very small capillary thickness, or simply the propagation of preexisting cracks).
We have carried out the measurement and evaluation of the exposure of structures to impulsive vibrations resulting from explosions and other sources, in accordance with the requirements of Portuguese Standard NP2074.
