Which Waterproofing Method Should You Opt For?

Introduction

• The concept of waterproofing helps prevent the
  ingestion 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
  coating is also referred to as asphalt coating.
  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 brittle and fragile.
  Bitumen coating is good against sunlight when
  mixed with acrylic-based polymers.

Bituminous Membrane

• Like bituminous coating, 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
  protective 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 coating 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 elongation
properties. Liquid waterproofing material is
extremely durable and can be combined with other
materials, like modified asphalt.

Cementitious Waterproofing

• Cementitious waterproofing is the most popular
  kind and is used in interiors that are prone to
  water, especially places like toilets.
  Cementitious waterproofing is partially flexible
  and partially rigid. The rigidity does act as a
  disadvantage as this coating is not exposed to
  sunlight, and it wouldn't be prone to constant
  expansion or contraction.

7
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 its time
  you considered getting 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.
