There are many different waterproofing methods and materials available, including:
- Waterproofing perforated film
- Polymer membranes
- Hydrophilic rubber
- Surface waterproofing (acrylic, bitumen, silicone rubber, polyurethane mastic, etc.)
- Sprayed waterproofing materials (poly-urea, acrylic formulations, liquid rubber, etc.)
- Injected materials (polyurethane, silicate resins, cement, emulsions, etc.)
- Penetrating materials
To give you a better idea of which waterproofing methods would be best for your home, here is an overview of some of the most popular waterproofing methods:
Polymeric membranes are extremely versatile, and they are a perfect choice for flat roofs. They can be used on new constructions, renovations, or to repair roofing. This popular synthetic material can provide long-lasting waterproofing that will keep roofing in excellent condition for years. Polymeric membranes can last for up to 25 years, plus they’re fire-resistant and environmentally friendly.
Coating waterproofing materials include:
- Bitumen-polymer mastics
- Polymer mastics
- Bitumen-rubber mastics
These can be divided into groups of hot mastics (those which need to preheat to 320°F) and cold mastics (those which do not require preheating).
While some cheaper forms of bitumen-mastic waterproofing may only last up to 5 years, others will last at least 20 years. They are ideal for flat roof waterproofing, and they are perfectly suited to concrete, wood, and metal.
Paint waterproofing can be applied by hand or can be sprayed. You should do it creating 2-4 layers for greater strength. The thickness of the waterproofing layer is only about 1-1,5 inches. Over the fresh insulation fine sand is sprinkled in order to cement the coating. The average life of paint waterproofing is about 5 years.
Roof Waterproofing Foil
These are the easiest (and most inexpensive) option for waterproofing pitched roofs, including slate, tile, and metal roofs. Most of the time, waterproofing foil is used for insulation in attics and lofts along with mineral wool and polystrene.
