Have you ever witnessed a coated surface that allows water to seep through on a periodic basis? You might be perplexed and annoyed after putting in all the day’s work and achieving zilch! Well, that’s because of the quality issues that prevail. To ensure maximum protection from water seepage, hire Sky Chemical Services, one of the most experienced companies in Pakistan. Seal out moisture with our top-tier waterproofing surfaces. Durable protection for a lasting, resilient finish.

Apart from quality issues, the membrane’s thickness is also a potent factor to consider. Inaccurate measurement of the layer can lead to potential leaks in walls and other surfaces. Every chemically-bonded layer has a specific thickness of its own: For example, FDP (flexible polymer-modified thick coatings) is applied at 3mm and MDS (modern drainage system) is applied at 2mm.

Coating thickness plays a crucial role in the effectiveness and durability of waterproofing systems. It determines the level of protection to the underlying surfaces and the overall performance of the waterproofing barrier. Moreover, it can withstand the test of extreme weather, toxic materials, and UV rays.

Following are several reasons why coating thickness is important.

Water Resistance

The primary purpose of waterproofing is to prevent moisture penetration through walls, roofs, and other surfaces. Coating thickness strengthens the ability of the waterproofing system to resist water ingress. A thicker coating forms a more robust and reliable barrier, minimizing the risk of water leakage and potential damage.

Structural Protection

Coating thickness ensures protection against moisture-related issues that can compromise the structural integrity of the building. Excessive moisture can lead to material deterioration in the form of cracks, holes, and flaking. A thick waterproofing coat acts as a shield, preserving the strength and longevity of the structural components.


A thicker coat provides better durability and longevity compared to a thin coating. It enhances the resistance to wear and tear, abrasion, and environmental factors, such as UV radiation, temperature fluctuations, and chemical exposure. A thicker coat reduces the need for frequent repairs or recoats. In addition, it extends the lifespan of the waterproofing system.

Crack-Bridging Ability

Buildings and structures are prone to movement because of settling, thermal expansion and contraction, or seismic activity. Coating thickness plays a critical role in the crack bridging ability of a waterproofing system. A thick coating can accommodate minor substrate movements and bridge small cracks. Moreover, it maintains the continuity of the waterproofing layer and preventing water infiltration through vulnerable areas.

Adhesion and Bonding

Coating thickness influences the bonding properties of the waterproofing material to the substrate. A thicker coat allows for better adhesion, creating a stronger bond between the waterproofing layer and the surface. On the other hand, spalling and wrinkling issues can occur if the grip is affected by moisture or other factors.


The desired thickness of waterproofing chemicals is specified on the product covering. Following the guidelines and applying the coating at the recommended thickness helps achieve a consistent and uniform coverage. Inconsistent or uneven thickness can result in weak spots, compromising the overall performance of the waterproofed surface.

Compliance with Regulations and Warranties

Whether its explicit or implicit warranty, buyers need to adhere to every clause and understand the legal obligations. Contractors and builders follow the standards of chemical application to ensure optimal results. However, in case of defect or expiry, a claim can be made by the purchaser for a new product.
