This system prevents unwanted moisture from seeping into your walls, thereby allowing mold to grow. Mold can impact our health in a negative way. It also prevents damage caused due to water seepage which can ruin the structural integrity of your home.  Moisture also causes metals to rust. As you know unhealthy living areas and weak foundations will affect the property value of your house. Also, waterproofing systems can open up the basement area and thereby increase the utility of your home’s square footage. This also helps in increasing the value of your house in the market.

 

There are some common types of waterproofing methods used in construction industry.

1.Sheet based waterproofing membranes:

these are membranes that arrive at the site in the form of rolls. These are then unfurled and laid on a firm surface. The most common type of sheet based membrane is a bituminous waterproofing membrane. This type of membrane is stuck to the substrate with a hot tar based adhesive using blowtorches. 

Self-adhesive compounds comprise asphalt, polymers and filler; additionally, certain resins and oils may be added to improve adhesion characteristics. The self-adhesive type has low shelf life as bonding properties of the membrane reduces with time.

 


2. Cementitious Waterproofing Method :

types of waterproofing

Cementitious or bitumen based products applied internally, externally or sandwiched within the structure.can be used for new build constructions.

This method is often used in the internal wet areas such as toilets. This method is usually a rigid or semi-flexible type waterproofing, but since it is used in internal areas such as toilets, it is not exposed to sunlight and weathering. Thus cementitious waterproofing does not go through contract and expansion process.

 

 


3. Liquid applied waterproofing membranes

TYPES OF WATERPROOFING METHODS IN CONSTRUCTION

Liquid membrane is a thin coating which consists of usually a primer coat and two coats of top coats which are applied by spray, roller, or Brush.

These are generally considered to be superior to sheet based membranes as they are joint-free. However care must be taken in application to provide just the right thickness. The membrane can tear or break if it is too thin. The adhesion of the membrane to concrete must be good.
