cement injections into the walls
It often happens that we have to carry out rehabilitation operations on some building structures, either for reasons due to age or for structural failures caused by the most varied reasons, among which seismic events certainly play a significant role. Whatever the cause, however, the walls of some structures need to be treated with rehabilitation interventions . Cement injections into masonry are one of these interventions which, for the sake of information, must not be the only masonry consolidation intervention.
Cement injections in the walls
As we have said, cement injections into masonry must not be the only intervention in a masonry that requires consolidation . Localized interventions, in fact, as the only type of intervention, are not recommended. Instead, they must be included in a rehabilitation system for the entire structure.
A masonry consolidation practice involves mortar injections , a technique which is normally applied in stone masonry and which is characterized by high internal voids. This technique is a passive technique since it does not require the execution of operations that could alter the appearance or balance of the structure.
The necessary condition for applying this technique is that there are sufficient spaces that allow the binding mixtures to penetrate inside the masonry . The binding mixtures have the task of improving the mechanical performance of the wall by eliminating cavities and cracks.
The product application procedure
Cement injections into walls require an overall simple procedure. The binding mixture, in fact, can be inserted under pressure or by pouring into the voids , using nozzles. Binder mixtures are normally made up of inorganic binders such as lime or cement, or organic mixtures, such as resins, can also be used.
There are now different types of products on the market, you need to choose the one compatible with the structure to be treated by carefully evaluating the characteristics of the product and those of the structure.
