Engineered Waterproofing Solutions Thank you for the opportunity of introducing our revolutionary Waterproofing Technology. We have secured exclusivity for the marketing and application of Engineered Wateproofing Solutions which we believe provides a compelling business proposition. Our products for Building belong to the category of “protective agents for building materialsis. These are Class A a
nd yield an 80% absorption and capilitating action at 24hours with saturation of EWS80 Cream. We are able to offer a 15 year guarantee on workmanship and product integrity. Some background -
Water absorption causes the following problems:
? Reduction of walls insulating power
? Alga and moss growing which causes the degradation of the contaminated surfaces, and a veried number of ailments
? Formation of soluble salts which create efflorescences and cause superficial breakings and cracks essentially due to hygroscopic salts expansion
? Cracks and superficial scaling caused by expansive phenomena related to frost/defrost cycles of watery solutions absorbed by mineral materials
? Corrosion of concrete reinforcements. Possible solutions to thes problems are:
COVER WITH PROTECTIVE FILMS
? It is the most known solution
? It is not the optimal solution
? It is not a lasting solution
Problems:
Ø The film has not a suitable anchorage system on the surfaces
Ø The film has a short chemical/physical and mechanical resistance
Ø The film creates some modifications to the steam permeability
Ø During the time the film is affected by chromatic change, therefore the treatment of natural stones is not possible
SOAK WITH WATER-REPELLENT MATERIALS
? It is a less known solution
? It is a definitive solution
? It fulfils the international regulations concerning the characteristics requested to the protective agents for stone and cementitious materials
? It is the solution that Achitex Minerva follows
The best solution, which grants the best results, is soaking till saturation with organic substances. Normally are used:
- Silicone Resins
- Silanes of different nature and with different characteristics.
? They are soluble also in polar solvents and water
? They react with silicates and chemically anchor to the material, even with humidity
? They have a high penetrating and polymerizing power.
? The best ones assure an excellent alkali stability
With the soaking treatment, the action of UV rays loses considerably its importance, since the penetration of the soaking agent in the building material is higher than the rays penetration
Trust this information has been helpful in conceptualizing this solution and await your next instruction. Kind regards
