Waterproofing Waterproofing of concrete structures by mineralization. It is a structural waterproofing intervention. In fact, the concrete is waterproofed from inside.

The process starts on the surface and migrates inwards. With this feature the waterproofed structure does not need any further protection. It has a unlimited duration, and the waterproofing is guaranteed both in positive and negative thrust up to 25 atm.






The intervention of waterproofing consists of the following stages:

• Surface preparation by mechanical removal of the concrete defects
• Opening of the capillary by water wash at 250 atm
• Concrete reprofiling by applying waterproofing grout and anti-shrinkage mortar
• Water wash of the surfaces
• Application of 2 fresh-on-fresh layers of X-tra (capillary penetration cement)
• Hydration of the surfaces for a few days


Types of executable interventions (on concrete structures only):

• Raft foundations
• Basements
• Elevator shafts
• Depuration tanks
• Drinkable water reservoirs
• Marine structures
• Structures in contact with sulfureous water
• Structures subjected to high water pressure

The concrete microcracks are closed (see picture) by X-tra through crystalization.


X-tra blocks humidity and infiltratrations

Underground water penetrates concrete and rises towards the surface through capillary and microcracks without hindrances; the consequences will be mould, humidity, infiltrations both on the floor and on the walls.



X-tra waterproofs concrete by creating a crystalline barrier that expands inside the capillaries and reacts against infiltrations day after day.
