Waterproofing

Waterproofing a surface means stopping it from absorbing water or other liquids. Water absorption and seepages are harmful because they involve deterioration of the structure, detachment of the coating on the other side of a wall or a slab, contamination of liquids in a tank (underground drinking water tanks) or contamination of the soil in case of purification tanks or tanks which may contain possible polluting agents.

Resimix waterproofing technology

Most waterproofing operations on flat coverings and on earth retaining walls are carried out using laid rolls of bituminous sheaths.
This technology enables constant thickness of the coating and high speed of work execution.

However, if a hole forms on the sheath for any reason, it gets cut or it detaches from the concrete, water will find a way to penetrate between the sheath and the support: as it is very difficult for it to exit from the sheath, it will look for a way in the wall thereby causing seepage.
This problem is not to be underestimated because the point where the seepage of water happens generally does not correspond to the one where the sheath deteriorated.
This problem can be easily solved on a flat coating, but in case of a wall or underground tank the only solution is to dig and look for the water leak which can be very hard.

With a coating with spatula, spray or roller/brush-applied waterproof resins, there is full adhesion to the support: if a sheath made this way gets perforated or cut, water cannot seep and run under the coating because the latter fully adheres to the support leaving no room for the water.
This work takes more time compared to traditional sheaths but also offers further guarantees.

What gets waterproofed?

• Containment and/or security tanks;
• terraces;
• roofs, especially cantilever and flat roofs;
• bridges and pedestrian walkways;
• brackets placed on flat covers; 
• raceways, connecting bases, pipes and concrete works of adduction; 
• walls and surfaces in the industrial and civilian construction; 
• concrete structures: aqueducts, containment walls.
