Top Waterproofing Materials for Malaysia’s Climate: A Throughout Guide by Chemind Industries

When you initially approach a basement waterproofing service, you’ll receive insights into a range of waterproofing materials, along with recommendations for the most suitable solution. The selection process takes into account your building’s specific waterproofing requirements and your budget constraints.


In this blog post, we aim to offer an exhaustive compilation of water-resistant materials utilized by professional contractors, delving into a thorough explanation of various waterproofing methods employed.

Exploring Waterproofing Methods in Depth

Let’s delve into the assortment of building waterproofing types utilized by specialists, each validated and proven through testing:

  1. Sprayed
  2. Injection
  3. Lining
  4. Rigid
  5. Paintable
  6. Plaster

The choice of method and materials used for waterproofing depends on the particular area of the building requiring insulation. Here are the primary scenarios:

Roof Waterproofing Applications

The roof, being one of the most vulnerable sections of a building concerning water penetration, demands attention. While roofing materials are typically water-resistant, additional waterproofing materials become imperative due to the extensive wear and tear experienced by roofs over their expected lifespan of 4-5 decades.


These additional materials are applied either as a protective coating over the roof or installed beneath it as part of the roof structure. A professional contractor evaluates the optimal waterproofing products based on your roof type and prevailing climatic conditions in your region (such as the average number of rainy days per year and air humidity).

Wall Waterproofing

Waterproofing materials for walls necessitate more than mere water resistance; they must incorporate vapor or air barriers. Without these barriers, moisture may become trapped in the masonry and woodwork beneath the insulation, fostering the growth of mold, mildew, and fungi.

Waterproofing for Balconies and Terraces

Materials used for waterproofing balconies and terraces must possess specific attributes like UV resistance and flexibility. Balconies and terraces experience slight movements due to temperature fluctuations. Rigid waterproofing materials, over their lifespan, tend to crack and necessitate early repair or replacement.

Types of Waterproofing Materials

Now, let’s delve into an extensive list of waterproofing materials, focusing on their application on roofs, as previously promised.


Among the array of waterproofing materials available, Polyurethane stands out for many due to its myriad advantages that other alternatives lack. Prioritize learning about this material before investing time or money as it ensures selecting the ideal material tailored to your specific requirements. Polyurethane offers an exceptionally smooth waterproofing membrane and effectively seals capillary cracks, reducing concrete water absorption. It also fortifies the concrete’s surface.

Cementitious Coating

Consisting of a powder blend of sand, organic and inorganic chemicals, and silica-based materials, cementitious coating, when combined with lime, triggers a hydration reaction, forming a waterproof seal. Its ease of use makes it a preferred choice among experts for various concrete structures, providing a long-lasting watertight seal if applied as per the manufacturer’s instructions.

EDPM Rubber

This synthetic rubber substance serves as a highly effective roofing waterproofing material, offering versatility in applications. It’s durable, composed of ethylene and propylene, and notably different from silicone. EPDM rubber’s main application is roof coating and is also utilized in automobiles for sealing purposes.

Rubberized Alphalt

Primarily used in commercial roofing, rubberized asphalt effectively protects against harsh weather conditions. It’s flexible, exhibits low moisture vapor permeance, and can adapt to extensive vegetative or intensive roofing assemblies, ensuring optimal results and durability. Additionally, it finds use in waterproofing RVs and campers.


Though not the most budget-friendly option, thermoplastic boasts immense waterproofing power, providing durability surpassing many alternatives, with a lifespan of over 50 years on average. Its ability to transform from solid to semi-solid when heated allows it to withstand impact effectively, making it suitable for various applications beyond waterproofing.

Bituminous Membrane

This waterproofing type suits diverse applications in both commercial and residential structures. However, it primarily consists of crude oil, making it less sustainable. Additionally, it struggles in high-temperature zones, shortening its lifespan under prolonged exposure to UV radiation.

PVC Membrane

PVC Membrane serves as a common roofing material, offering significant advantages such as water resistance and vapor permeability. Reinforced with a base of glass fiber or polyester mesh, this material finds extensive use not only in roofs but also in tunnels, pools, and underground structures.

In Conclusion

As you consider the best waterproofing material for Malaysia’s climate, it’s crucial to evaluate each option’s specific advantages, costs, and suitability to ensure optimal protection against water infiltration in your building.
