Since Singapore has a tropical environment and a lot of rain, waterproofing is essential when building there, as everyone knows. So in addition to minimising surface or external damage, effective waterproofing materials preserves the structural integrity and longevity of buildings by inhibiting the growth of mold and water infiltration. 

In Singapore, many waterproofing materials and techniques are utilised to overcome the distinct problems because of the country’s climate. We’ll talk about the types of waterproofing materials utilized in Singapore in this thorough guide.

Let’s get into it!

Polyurethane (PU) Waterproofing Coatings

Did you know? In Singapore Polyurethane (PU) coatings are common for waterproofing because of their adaptability as well as durability. By minimising the water absorbency of the concrete as well as providing an efficient capillary crack filling, it offers a seamless membrane and also a seal. The top layer of concrete will harden as a result of polyurethane’s tendency to penetrate the surface deeply.

Are your room walls or floors cracked? Worry not!

When it comes to wall and floor cracks and joints that frequently result in unintentional leaks, professional contractors like RSF Waterproofing provides PU Injection, a long-lasting fix. In order to provide long-term protection against water incursion, this method produces a waterproof barrier and long-lasting sealant.

Are you aware of this? Balconies, decks, tanks, and flat roofs are just a few examples of the many weather-exposed buildings that polyurethane liquid membrane can be used on. It resists water, preventing leaks without compromising joints. Its permeability allows water vapour to pass through while ensuring full surface adhesion.

Advantages

Thermoplastic

Because it’s so much stronger than other waterproofing materials, thermoplastic—also called thermosoftening plastic—is greatly sought after for waterproofing purposes. It offers resistance to abrasions and tears, impressive bending and tensile strength, substantial elongation before breaking, resilience to low temperatures, minimal long-term deformation, and resistance to various chemicals such as ozone, oxygen, oil, and fuel.

With an average lifespan of up to 50 years or more, thermoplastics ensure enduring waterproofing efficacy. Moreover, they preserve the flexibility and softness of base materials, contributing to their versatility. These attributes culminate in the creation of technical textiles capable of withstanding extensive wear and environmental pressures across a multitude of applications.

Advantages

Bituminous Coating Membrane

In Singapore, tar or asphalt membranes, often known as bituminous membranes, have been utilised for waterproofing purposes for an extensive period of time. An extremely viscous, sticky liquid derived from coal tar or asphalt is called bumminous.

Bituminous waterproofing is frequently used when building a home or business. Its flexibility and strong adherence assure long-lasting waterproofing. It is commonly found in roofs, basements, below-ground structures, bridges, and various other constructions.

Do you know? Bituminous coatings, which are frequently found in basement waterproofing materials, provide strong defenses against water incursion and create a long-lasting barrier that successfully seals and shields below-grade structures from moisture damage.

Also, bituminous waterproofing materials in construction are mainly projected to provide fundamental protection against water infiltration,  guaranteeing the structural integrity as well as longevity of buildings in various applications.

For flat roofs, basements, and below-grade applications in particular, bituminous membranes are ideal because they provide good waterproofing qualities. For locations with a lot of foot traffic or mechanical strains, they are perfect because of their high tensile strength and resilience to punctures. 

Advantages

Nano Waterproofing

Nanowaterproofing represents a contemporary approach to applying hydrophobic protection to various surfaces, such as roofs, walls, and floors. These coatings effectively prevent water penetration while allowing vapor transmission. When professionally installed, RSF’s waterproofing nanoparticle coatings can last up to 10 years with appropriate maintenance.

Nano waterproofing comprises a liquid-based spray that effectively waterproofs surfaces upon application. Its versatility extends across various materials, including concrete, cement, masonry, wood, and marble. Beyond building surfaces, it finds application in waterproofing fabrics and automobiles as well.

Advantages

Cementitious Waterproofing

Let me tell you that a variety of cement additives are utilised in cementitious waterproofing systems to enhance their waterproofing capabilities. Do you know that these technologies provide a solid, protective layer on top of concrete substrates, thereby preventing water penetration?

Basements, foundations, and retaining walls are examples of below-grade constructions that frequently use it. Moreover, bathrooms, swimming pools, and water tanks can all use it. But for maximum efficiency and longevity, appropriate surface preparation and curing are necessary.

Cementitious waterproofing materials for walls, such as cement-based coatings or additives, give a strong barrier against water infiltration, making them a popular choice for interior basement walls and other wall surfaces requiring efficient waterproofing.

Advantages

Liquid Applied Membranes (LAM)

Liquid-applied membrane (LAM) is a typical liquid-based waterproofing material used in roofing construction. After being sprayed over surfaces, this liquid material dries in the atmosphere to form an elastomeric waterproof membrane that has a texture similar to rubber. Numerous substrates, such as bitumen, concrete, and asphalt, can be treated with it.

Liquid membrane waterproofing materials for concrete offer versatility as well as effective protection against water penetration. They improve concrete surfaces’ longevity and durability by forming a smooth barrier that sticks to them nicely.

However, it is important to apply with great care to ensure the right thickness because too-thin membranes run the risk of rupturing or ripping. LAM stands out for its durability and cost-effectiveness, making it particularly suitable for roof refurbishments and waterproofing projects. Additionally, it boasts vapour-permeable properties, enhancing its overall utility.

Advantages

EPDM Rubber

Epoxy propylene diene monomer (EPDM) rubber is a synthetic material that possesses exceptional durability and pliability. Rubber with EPDM is highly regarded for its ability to keep things waterproof and is often used in roofing. To give rooftops waterproofing qualities, it is usually stacked over different substrates, such as thermal insulation and vapor barriers.

Are your rooftops in need of protection?

If yes, then worry not! In addition to protecting your home from water damage and ensuring long-term durability, EPDM will keep your roof continuously safe.

You might not know that EPDM rubber is frequently utilised in rooftop waterproofing materials, it offers dependable and long-lasting defense against water intrusion, making it the best option for guaranteeing the integrity as well as longevity of the roof.

Because EPDM rubber has such remarkable tear resistance, it is the finest material for roofing exposed to adverse weather conditions like intense heat, UV rays, and rain. It is not susceptible to deterioration even when exposed to temperatures as high as 150°C and prolonged periods of time outdoors.

Advantages

Silicone Sealants

Did you know that silicone sealants are utilised for sealing joints, gaps, as well as cracks to prevent water infiltration? They are utilised in conjunction with other waterproofing materials and are also recognised as one of the finest toilet waterproofing materials.

One of the popular option for sealing applications is silicone sealant. Imitating a flexible as well as strong rubber composite, it is recognised for its strength, elasticity, and durability. They are frequently utilised in showers, bathtubs, sinks, vents, windows, and even roofs.

Advantages

PVC Waterproofing Membrane

Another waterproofing material is Polyvinyl chloride (PVC), which is widely used for waterproofing, particularly in underground buildings, swimming pools, and roofs.

This membrane effectively keeps water out of buildings. It is recognized for its remarkable water resistance. Moreover, it facilitates the escape of water vapor, reducing the probability of moisture accumulation.

Did you know that glass fiber or polyester mesh reinforcement is typically included in PVC waterproofing membranes? It has two main types: reinforced and unreinforced membranes. However, reinforced membranes are more durable than unreinforced membranes, which are more flexible.
