Waterproofing is an essential aspect of construction, whether it’s for a new building or renovating an existing one. It’s the process of preventing water from infiltrating a structure, which can lead to damage, structural issues, and even health concerns due to mold and mildew growth. Two common methods of waterproofing are cementitious and bituminous waterproofing.
Cementitious waterproofing vs bituminous waterproofing
Cementitious and bituminous waterproofing are two of the most common types of waterproofing used in construction. Both types of waterproofing have their own advantages and disadvantages, and the best type of waterproofing for a particular project will depend on a number of factors, including the substrate, budget, and expected service life.
Cementitious waterproofing is made from a mixture of cement, sand, and water. It is a rigid and durable material that is well-suited for waterproofing concrete and masonry surfaces. Cementitious waterproofing is also relatively inexpensive and easy to apply.
Advantages of cementitious waterproofing:
- Durable and long-lasting
- Easy to apply
- Good adhesion to concrete and masonry surfaces
- Can be used to waterproof a variety of surfaces, including roofs, terraces, basements, and bathrooms
Disadvantages of cementitious waterproofing:
- Not as flexible as bituminous waterproofing
- Can crack if not applied properly
- May not be suitable for waterproofing areas that are subject to movement
Bituminous waterproofing is made from asphalt or bitumen. It is a flexible and water-resistant material that is well-suited for waterproofing a variety of surfaces, including roofs, terraces, balconies, and foundations. Bituminous waterproofing is also resistant to UV radiation and chemicals.
Advantages of bituminous waterproofing:
- Flexible and water-resistant
- Resistant to UV radiation and chemicals
- Can be used to waterproof a variety of surfaces
- Can be applied in a variety of ways, including hot mopping, spray-on, and self-adhesive
Disadvantages of bituminous waterproofing:
- More expensive than cementitious waterproofing
- More difficult to apply
- Not as durable as cementitious waterproofing
- May not be suitable for waterproofing areas that are subject to high temperatures
