Types of Waterproofing Methods Used

As a potential real estate investor in Singapore, you have found that sweet spot where your new dream project will finally be realized. You have hired a project manager and other construction workers before beginning work.

If you are familiar with the Singapore weather, then you know the island receives a lot of rainfall and this can be disruptive to homes. Majority of Singaporeans homes are designed with concrete which need to be waterproofed to prevent rain water from seeping into the house.

Below are types of waterproofing Singapore methods you need to know about.

Liquid water proofing membrane

This is basically a very thin coating that consists of a basic primer coating as well as another two layers of top coatings. This type of waterproofing is flexible and has elongation properties which can reach 280% level. It can be spray applied since it is made of asphalt that has been polymer modified. They are available in multiple grades for rollers, trowels and sprays. The strength and resilience of the membrane depends on what polymer the producer has used. It is inexpensive but is known to make one part of the roof to be thicker than the other. This is attributed to the liquid nature of the material.

Bituminous coating

The material is made from bitumen based products which isn't suitable for areas exposed to direct sunlight. When exposed to the sun for long, it can become weak and flimsy. This can be corrected by mixing it with flexible materials like acrylic or polyurethane polymers. Its flexibility is attributed to the amount of solids found in the polymer which is mixed with bitumen in order to improve the finish.

Also referred to as asphalt coating, it is an excellent protective coating and waterproofing agent which is commonly used on concrete foundations.

Cementitious waterproofing

This is used in internal wet areas like the bathroom and toilet area. It is formulated to be semi flexible while others can be rigid. The materials used can be sourced from different suppliers of masonry products and furthermore, they are easy to mix and apply.

It is not suitable to be expose it to the sunlight which could lead to weathering. This is because it does go through the contract and the expansion process.

The self adhering compounds consist of different types of polymers, asphalt and fillers. Sometimes, oils or resins are also used to help increase its adhesive types. It does not last long and has to be used quickly as the bonding properties are known to reduce with time.

The Torch on membrane is found in two types namely covered and exposed membranes. The exposed membrane comprises of mineral based construction aggregate which is known to resist the harsh elements from being exposed to sun and rain. All the contractor has to do is apply a protective layer of screed which prevents any breakage in the membrane.

When applying the protective screed, often made of cement mortar, one has to be really cautious. The ratio of the cement is too high and the cement has to be well mixed during the whole process. There are purchasable cement mortars which have already been mixed with accurate and precise ratios and excellent quality.

Polyurethane liquid membrane method

For flat roofs, this method is commonly used and is known to be expensive but it offers higher flexibility. It is susceptible to moisture therefore before it is applied; careful evaluation needs to be done especially when reading moisture content. If this is not done, the membranes could potentially start peeling leading to leaks and crack formation.

Final Thoughts

Waterproofing is vital especially if you are planning to construct a home in Singapore. The weather is rainy and if your roof or floor has cracks, you will experience leaks. You need to consult with specialists to ensure you have the right method for your construction project.
