Singapore’s tropical climate and high humidity levels make waterproofing an essential aspect of building construction and maintenance. Waterproofing is the process of making a structure or object resistant to water penetration and damage. In this article, we will take a look at the most common waterproofing methods used by contractors in Singapore.
- Bituminous Waterproofing: Bitumen is a waterproofing material that is widely used in Singapore. It is applied as a hot liquid, which then solidifies to form a waterproof barrier. Bituminous waterproofing is commonly used in flat roofs, basements, and other underground structures.
- Cementitious Waterproofing: Cementitious waterproofing is a popular method used in Singapore. It involves the application of a cement-based waterproofing material to a surface. This method is suitable for surfaces that are subject to high levels of water pressure, such as retaining walls and swimming pools.
- Polyurethane Waterproofing: Polyurethane is a flexible waterproofing material that is commonly used in Singapore. It is applied as a liquid and forms a waterproof barrier upon curing. This method is suitable for surfaces that are subject to movement, such as expansion joints and bridges.
- Liquid Applied Membranes: This method involves the application of a liquid waterproofing membrane to the surface. The membrane forms a waterproof barrier upon curing. This method is suitable for surfaces that are difficult to access, such as balconies and terraces.
- Sheet-based Membranes: This method involves the application of a sheet-based waterproofing membrane to the surface. The sheets are overlapped and sealed to form a waterproof barrier. This method is suitable for surfaces that are subject to high levels of water pressure, such as foundations and basements.
In conclusion, waterproofing is an essential aspect of building construction and maintenance in Singapore. The above-mentioned methods are the most commonly used by contractors in Singapore. It is important to choose the right method for the specific surface and water pressure level to ensure effective waterproofing. It is also important to choose a reputable and experienced contractor to ensure the quality of the waterproofing work.
