THE IMPORTANCE OF WATERPROOFING MEMBRANE IN CONSTRUCTING
                     THE IMPORTANCE OF WATERPROOFING MEMBRANE 
IN CONSTRUCTING
A house is more than just a place where people live; it is an 
embodiment of the people who live there. The feelings and 
memories that a family shares in that space are what make 
a house a home. It’s not only about putting up walls, 
ceilings, and floors; it’s about creating an environment that 
makes you feel comfortable, relaxed, and happy in every 
manner. While perfect aesthetics are usually the utmost 
priority when it comes to the construction and design of 
any property, the durability of these aesthetics is always at 
risk if effective roof waterproofing isn’t taken into account. 
Water can seep into the structure, weakening it by 
corroding the re-bars. Excessive water seepage can lead to 
fungal growth, short circuits, and paint flaking, lowering the 
residential property’s inherent value.
Many of these problems can be readily solved if an 
appropriate waterproofing solution is chosen 
throughout the framing process. In this situation, the 
mother slab can be waterproofed, and the 
waterproofing can be topped with a 15–20 mm thick 
cement concrete layer. Customers are always 
apprehensive of burdensome civil works if the roof has 
already been cast and is experiencing water seepage 
concerns. Modern exposed waterproofing membranes 
are the result of this demand. These membranes are 
exceptionally flexible, UV resistant, and able to 
withstand human traffic, resulting in an attractive and 
durable water-resistant roofing.
Let’s take a look at the factors to consider while choosing a waterproofing system 
to better comprehend the process.
• The state of the foundation
• Cracks that have already formed should be treated.
• Whether it’s waterproofing beneath the tiles or waterproofing that’s visible
• Waterproofing membrane elastomeric property (elasticity)
• Rooftop traffic expected
• Waterproofing membrane type
Let’s take a closer look at these points:
1. The state of the foundation substrate
Waterproofing membranes may be required for a variety of substrates, including 
tiled surfaces, china chips surfaces, concrete surfaces, damp surfaces, moss/fungus-
infested surfaces, and so on.
Waterproofing adhesion varies from surface to surface, resulting in variable 
performance for the end-user. A sufficient surface preparation advised by the 
manufacturer, as well as a correct primer, are essential for obtaining appropriate 
adhesion to the base substrate.
2. Cracks that have already formed should be treated.
Existing fractures operate as floodgates, allowing water from the roofs to easily 
seep into the internal walls of ceilings and walls, causing fungus growth and 
paint film stripping.
Cracks must be opened using a mechanical grinder or chisel and hammer, then 
filled with polymer-modified cement putty squeezed in. Allow 24 hours for the 
filled cracks to dry.
3. Whether it’s waterproofing beneath the tiles or waterproofing that’s 
visible
At this time, waterproofing membranes exist in a range of shapes and sizes. Each 
waterproofing membrane is designed to work in a certain climate.
On the base concrete/mother slab, an under-tile waterproofing membrane is put and 
then covered with concrete/tiles/china chips. Under-tile waterproofing membranes 
can be less expensive and less puncture-prone. However, pinpointing the source of 
damage in the event of a leak might be difficult, and the entire operation may have 
to be redone.
Waterproofing membranes nowadays are highly flexible, UV resistant, and resistant 
to normal human traffic. The benefit of these membranes is that they avoid the need 
for time-consuming civil work and are reasonably easy to install. If there is any 
damage, it is simple to repair it.
4. The waterproofing membrane’s elastomeric property (elasticity).
Flexible waterproofing membranes can adjust to temperature changes better than 
rigid membranes. While cementations waterproofing membranes are hard and 
suitable for under-tile waterproofing or places with little rainfall, acrylic and 
polyurethane-based waterproofing provide superior elastomeric and UV stability, as 
well as the ability to be used in exposed settings.
Any waterproofing system’s elastomeric feature is valid for a specific thickness. The 
qualities of a membrane may be harmed by diluting it or applying it with a thinner 
film thickness or fewer layers. Under any circumstances, such practices must be 
avoided.
To avoid water gathering or puddling, the right slope towards the drain pipes must 
be maintained before laying a waterproofing membrane.
5. The amount of traffic expected on the roof
While the manufacturer’s specified thickness or number of coats should be followed, 
it’s also important to consider the expected surface roughness as well as traffic or 
movement on the floor. The membrane must be resistant to traffic and should not be 
punctured by it.
Polyurethane membranes outperform cementations membranes in terms of abrasion 
resistance. Acrylic analogues are perfect for high-traffic areas such as podiums, 
running tracks, and other similar situations. Acrylic waterproofing membranes can 
be a cost-effective and long-lasting solution for non-traffic regions such as a 
building’s outside walls.
