Which Waterproofing Method Should You Opt For?
                     Which Waterproofing Method 
Should You Opt For?
Introduction
The concept of waterproofing helps prevent the ingesti on of water into the surface or walls. 
Waterproofing has been changing constantly with the improvement in architectural designs and the 
availability of materials used during construction. It has become a common necessity these days to 
keep your house dry, from roof to basement. Keeping the walls dry also helps prevent insect 
infestations, mold, and building failures. Waterproofing can reduce wear and tear and increase the life 
span of a building too. It's highly essential to waterproof your house before the monsoon season, as 
one might tend to face issues like seepage of water into a house.
A bituminous coating provides a flexible coat, protecting the surface against water. Bituminous 
coati ng is also referred to as asphalt coati ng. These coatings are mostly used on concrete surfaces and 
are made from petroleum-based products. It is not suitable to expose it to sunlight, as it will become 
britt le and fragile. Bitumen coating is good against sunlight when mixed with acrylic-based polymers.

Bituminous Membrane
Like bituminous coati ng, the bituminous membrane is another 
popular waterproofing method used in low-sloped roofs. 
Bituminous membranes consist of asphalt, polymers, resins, 
and oils, which improve their adhesive characteristics. A 
protecti ve screed is applied to the membrane to prevent it 
from being damaged. The only downside to using the 
bituminous membrane is its low life span and reduced bonding 
properties over time.

Polyurethane Liquid Membrane
Polyurethane liquid membrane is extremely popular when 
waterproofing the roof area of a house. The roof comes into 
direct contact with the weathering and is prone to wear and 
tear. Polyurethane membrane is expensive, and the process of 
applying it is tedious. This membrane offers high flexibility and 
is quite sensitive to the moisture present on the surface. One 
has to evaluate the moisture content on the surface before 
applying this to prevent peeling or de-bonding of the 
membranes from the surface.

Liquid Membrane
Liquid membrane is a thin coati ng that usually consists 
of a primer coat and two top coats, which are applied 
across the surface and rolled on. This liquid membrane 
cures into a highly flexible rubbery coating with 
elongati on properties. Liquid waterproofing material is 
extremely durable and can be combined with other 
materials, like modified asphalt.

Cementitious Waterproofing
Cementi ti ous waterproofing is the most popular kind 
and is used in interiors that are prone to water, 
especially places like toilets. Cementi ti ous 
waterproofing is parti ally flexible and parti ally rigid. 
The rigidity does act as a disadvantage as this 
coati ng is not exposed to sunlight, and it wouldn't 
be prone to constant expansion or contracti on.

Metallic Sheet Wrapping
Thin foils of copper and aluminum are used for wrapping around concrete surfaces to prevent 
leaking problems. These metallic sheets are being sold with improved adhesives to prevent them 
from falling off  surfaces.
With monsoons around the corner, maybe it ’s time you considered getti ng some 
roof waterproofing to protect your house. With several materials to choose from, it eventually 
comes down to your needs when choosing the one for you.
