Waterproofing products are products used in the construction, remodeling, and repair of all types of works that prevent water, from any source, from entering construction.
What types of waterproofing can be used in construction?
- Synthetic waterproofing
- Natural waterproofing
- Stone waterproofing
- Metal waterproofing
When used each of these types of waterproofing?
It depends on the surface to be waterproofed and its capacity as a thermal insulator.
If a wall or wall does not have a good capacity or lacks an air chamber, no waterproofing can be applied. In these specific cases, a breathable product should be applied to avoid internal condensation on the walls.
Next, we will mention the characteristics of each type.
Synthetic waterproofing
What is synthetic waterproofing?
Asphalt fabrics: they are the type of waterproofing most used on ceilings. It comes from petroleum products, and its durability is more than ten years.
Nanotechnological waterproofing:
Products made with a formulation that acts at the atomic scale. It guarantees surface tightness and also allows it to perspire.
Breathable waterproof sheets:
Plastic fabric composed of fibers that do not degrade over time.
They should not be placed directly outdoors.
Polymeric resins:
Hot application
Durability: the manufacturer guarantees a duration of more than 25 years, maintaining its qualities
(DITE) Cold application polyurethane
Durability: over 50 years if the product is protected from the weather.
Acrylic resins
Cold application
Durability: the manufacturer: guarantees duration between 3 and 10 years, maintaining its qualities, depending on its formulation.
Epoxy resins
Cold application
Durability: the manufacturer guarantees a duration of 3 years, maintaining its qualities.
What are the natural waterproofing?
Those from the vegetable kingdom such as latex which is the most used
Different compounds from latex:
Chloro rubber:
- Weather stable properties.
- Cold application.
- Durability: the manufacturer guarantees a duration of 3 years while maintaining its qualities.
EPDM:
- Ethylene rubber.
- Cold application.
- Durability: the manufacturer guarantees a duration of 5 years while maintaining its qualities.
What is inorganic waterproofing of stone nature?
These materials can be:
Blackboard
Granite: less common of the two. Duration greater than 50 years, minimum maintenance.
Silicone: comes from silica in a liquid state. Durability: the manufacturer guarantees a duration of 3 years while maintaining its qualities.
Ceramic materials such as tile: ecological product. Durability: the manufacturer guarantees a duration of 10 years while maintaining its qualities.
Cement materials: Many possibilities to formulate this type of cement-based waterproofing. It may or may not be breathable, and it is advisable to review the product data-sheet. Durability: the manufacturer guarantees a duration of 3 years while maintaining its qualities. The more complex systems may have a longer duration exceeding 50 years.
One of these products is the cement-derived fiber cement, originally with added asbestos fibers, glass fibers are currently added.
What are inorganic waterproofing materials of a metallic nature?
These products are those used in certain constructions, especially in industrial-style homes, in industrial buildings and covering areas in multi-purpose facilities, with iron or concrete structure.
The products that they mainly use are:
- Zinc
- Copper
- Natural aluminum
- Lacquered aluminum
- Lead
- Stainless steel
- Galvanized steel
Titanium, this being a very expensive material, but it has been used in certain types of construction. These products are mainly used in roofs with excellent results, to prevent water from entering.
