Detailed Presentation of Waterproofing Methods.
So, what are the types of waterproofing for a building? Specialists in Polyurethane injection grouting for sale building materials use one of the following tried and tested waterproofing methods:
The choice of method and waterproofing materials depends on the part of the building you want to insulate. Here are the three main situations.
1. WATERPROOFING APPLICATIONS ON ROOFS
The roof is one of the two most vulnerable parts of a building when it comes to water infiltration. In general, roofing materials are waterproof, but this is not enough. A roof is subject to intense wear and tear and should last for at least 4-5 decades. it is necessary to add supplementary waterproofing materials.
They are either applied as a protective coating over the roof or installed under it, as part of the roof frame. A professional contractor will recommend the best waterproofing products depending on the roof type and the climate in your area (average number of rainy days per year, air humidity, etc.).
2. WATERPROOFING ON WALLS
Waterproofing materials for walls must offer more than just protection against water. They also need to incorporate vapor barriers or air barriers. Otherwise, moisture may become trapped in the masonry and carpentry, under the insulation, resulting in the spreading of mold, mildew and/or fungi.
3. BALCONY AND TERRACE WATERPROOFING
Waterproofing building materials for the balcony and terrace must have several specific characteristics, such as resistance to UV rays and flexibility. Balconies and terraces are subject to slight movements due to temperature variations. Rigid waterproofing materials would crack and need repair or replacement in a short time, under the average lifespan of these materials.
TYPES OF WATERPROOFING MATERIALS
As promised, we will give you now a comprehensive list of waterproofing materials.
Polyurethane is considered one of the best waterproofing materials. It can be applied seamlessly and penetrates the surface deeply and evenly. Thus, the polyurethane membrane will fill in even the finest cracks in concrete, reducing its water absorbency capacity. Another key benefit of polyurethane is that it resists oil, detergents, and various chemicals.
These characteristics and benefits recommend polyurethane as one of the most versatile waterproofing materials. It can be applied or walls, balconies, terraces, and walls.
As for the cost, it is in the premium range. The average application price is $10 per square meter of building.
2. CEMENTITIOUS COATING
Cementitious coating is a powder mix of sand, organic, and inorganic substances plus silica-based materials. It is very popular among waterproofing contractors because it is very easy to apply. They only have to mix the powder with a specific quantity of water and they can start the installation work.
The downside of this benefit is the lack of flexibility of cementitious coating. For this reason, we list it among the recommended waterproofing materials for the basement and foundation.
3. EPDM RUBBER
EPDM rubber is one of the recommended waterproofing materials for roofs. It is available in membranes with two thicknesses: 45 mils and 60 mils. Flexibility is the key benefit of this waterproofing product – a critical aspect for roof waterproofing, as it expands and contracts constantly due to temperature variations.
4. RUBBERIZED ASPHALT
This is one of the waterproofing products used especially on the roofs of commercial buildings. It is a very tough and flexible material, offering excellent protection against all weather conditions and has very low water vapor permeability. It also dries quickly, in 3-4 hours after application.
