This technique, applied to concrete and masonry walls, waterproofs cracks, cold joints and construction joints with DRYflexfoam injections.
The operation is carried out inside the building and without bulk excavation, and allows resolving problems of any size: from the small domestic crack to infiltrations of dams.
The resin may be injected also in the presence of water at pressure and the effectiveness is independent of the state of cracks.
The Drytech Systems are used, inter alia, in the restoration of diaphragms, tunnels, dams, sewage treatment plants, hydroelectric power stations, parking lots, etc. |

The dampness from capillary rise occurs primarily in masonry or full brick walls in contact with the ground.
The restoration of damp walls should always be faced with respect to the physics of construction.
Dampness usually occurs in 3 shapes:
> Formation of salts which break off paint and plaster:
capillary rise or infiltrations.
> Dark spots and fungi >> formation of condensation and therefore thermal problem.
> Combination of salts and fungi >> thermal problem and, simultaneously, salt saturated walls due to capillary absorption.
The injection techniques by absorption or by DRYsec/DRYflex fogging combined with consolidation plasters.
WTA with thermal insulation, are the most effective restoration techniques. |

The consolidation techniques are used in particular in walls in masonry or brick bearing structures and in static cracks of reinforced concrete, requiring structural
reinforcement, sealing of cracks and filling of real hollows.
Depending on each particular case, injections of polyurethane resin, cement or epoxy, are carried out. |
