Waterproofing is an essential aspect of building construction in Singapore, where heavy rainfall and high humidity can lead to water infiltration and structural damage. In order to protect buildings from water damage, developers and builders must choose the appropriate waterproofing system for their project. In this article, we will discuss the different types of waterproofing systems commonly used in Singapore, and their respective advantages and disadvantages.
Advantages and disadvantages of liquid applied membranes
One of the most popular types of waterproofing systems used in Singapore is liquid applied membranes. These systems consist of a liquid coating that is applied to the surface of the building, where it hardens to form a waterproof barrier. The advantage of liquid applied membranes is that they can be applied to a wide range of surfaces, including concrete, brick, and metal. They are also highly flexible, which allows them to move with the building and prevent cracking.
Advantages and disadvantages of sheet membranes
Another popular type of waterproofing system used in Singapore is sheet membranes. Sheet membranes consist of a waterproof material, such as PVC or TPO, that is applied to the surface of the building in large sheets. The advantage of sheet membranes is that they are easy to install and can be used on flat roofs or other large surfaces. However, they are not as flexible as liquid applied membranes, which means they are more likely to crack over time.
Cementitious waterproofing and crystalline waterproofing
In addition to these two types of waterproofing systems, there are also other options available, such as cementitious waterproofing and crystalline waterproofing. Cementitious waterproofing uses a cement-based material to create a waterproof barrier, while crystalline waterproofing uses a chemical treatment to make the concrete itself waterproof. Each of these systems has its own advantages and disadvantages, and should be chosen based on the specific requirements of the project.
Regulations and standards for waterproofing in Singapore
When choosing a waterproofing system for a building project in Singapore, it is important to consider the regulations and standards set by the Building and Construction Authority (BCA) and the Singapore Standards Council (SSC). These organizations provide guidelines for waterproofing that must be followed in order for a building to be deemed safe and structurally sound. Additionally, it is important to work with a reputable waterproofing contractor who has experience in the local climate and can provide a warranty for their work.
In conclusion, waterproofing is a crucial aspect of building construction in Singapore, where heavy rainfall and high humidity can lead to water infiltration and structural damage. There are many different types of waterproofing systems available, including liquid applied membranes, sheet membranes, cementitious waterproofing and crystalline waterproofing. Each of these systems has its own advantages and disadvantages, and should be chosen based on the specific requirements of the project and the regulations set by the Building and Construction Authority and the Singapore Standards Council.
