Waterproofing materials are crucial in protecting buildings from water damage. They create a barrier that prevents water from seeping into the structure, safeguarding foundations, walls, and roofs. There are various types of waterproofing materials, each designed for specific applications, such as bitumen for roofs or cementitious coatings for basements. These materials ensure long-lasting protection, reducing the risk of mould, corrosion, and structural weakening. Proper waterproofing not only extends the lifespan of buildings but also saves costs by preventing costly water damage repairs.
What Is Waterproofing Material?
Waterproofing material is a special substance that stops water from getting through. People use it to keep things dry and safe from water damage. Builders put it on roofs, walls, and floors. It acts like a shield against rain, moisture, and leaks. This material helps protect our homes, schools, and buildings from water problems.
We can find moisture-resistant material in many forms. Some look like thick paint, whilst others come as sheets or rolls. A study from Research Gate, entitled “Analysis of Water-Proof Properties of Building Waterproof Materials and Concrete Components”, shows that cement-based coatings improve anti-seepage performance, polyurethane coatings provide superior sealing by closing micropores and cracks, and SBS copolymer membranes form dense waterproof layers through hot-melt bonding. The study concludes that all three materials offer effective waterproofing, but proper material selection and construction methods are essential to enhance building durability, safety, and service life., showed that recurrent leakage problems occur when design, installation, and maintenance are not adapted to local climate and use patterns.
A study from Science Direct entitled “Investigating Effective Waterproofing Materials in Preventing Roof Leaking; Initial Comparative Study: Malaysia, U.K”, showed that some waterproofing products distributed in Malaysia originate from companies with operations in Singapore, reflecting the use of globally engineered systems suited to tropical climates. For Singapore, this suggests that selecting high-quality, internationally tested waterproofing materials is critical to improving durability, preventing roof leakage, and ensuring long-term building performance.
What Are the Types of Waterproofing Materials?
The different types of cementitious waterproofing include bitumen, cementitious, polyurethane (PU), EPDM (ethylene propylene diene monomer), PVC waterproofing membranes, TPO (thermoplastic olefin), rubberised asphalt, crystalline, geotextile, and acrylic options.
1. Bitumen Waterproofing
Bitumen waterproofing uses thick tar-like material to create strong waterproof barriers on building surfaces. Bitumen comes from petroleum and has been used for waterproofing for over a hundred years. It is completely waterproof and very durable in harsh conditions. Bitumen waterproofing comes in two main forms: liquid bitumen you paint on and bitumen sheets you stick down. Both create tough barriers that resist water, chemicals and soil pressure. Bitumen works especially well underground where it faces constant groundwater. It is one of the most reliable waterproofing methods for foundations and basements.
A study from the American Society of Civil Engineers (ASCE) entitled “Investigation of Antiaging Performance and Service Life of OMMT/SBS Modified Bitumen Waterproof Membranes”, showed that Adding 3% organic montmorillonite (OMMT) to SBS-modified bitumen improves aging resistance, thermal performance, and network structure, reducing chemical degradation. This enhancement extends the service life of bitumen waterproof membranes from 16.9 to 21.3 years, ensuring long-lasting waterproofing protection.
When to use:
- Building foundations and basement walls
- Underground car parks and structures
- Flat roofs on commercial buildings
- Bridge decks and infrastructure
