STRUCTURAL ENGINEERING

injecion of a sandstone wall<br/> for sealing and strengthening consolidation of masonry
Injections are performed through drill packers and injection hoses. In most cases an injection resin with low viscosity and slow setting (SPESAN WL SPESAN B) is used. Despite the high compressive and flexural strength of the resin it can absorb distortions within a certain range without failing.
