What is Cementitious Waterproofing Method?

Cementitious waterproofing method is one of the most popular method to protect structures.

This technique involves applying a cement-based mixture to surfaces, forming a non-porous layer. Its effectiveness, ease of application, and ability to create a durable final product contribute to its many applications.

Types of Cementitious Waterproofing Method

Rigid or Semi-Rigid Waterproofing:

Internal wet areas include restrooms, kitchens, and cellars, among others. Serves as a durable and very effective waterproofing substance. It is less adaptable than acrylic since it cannot be easily applied to regions of movement or cracking.

Flexible Cementitious Waterproofing Method:

Applied to external constructions and portions that are likely to move and vibrate. Can fill minor gaps and withstand substrate movement after installation. Polymers are occasionally used as back-up additions to enhance flexibility.

Application Areas :

Basements and Foundations: Prevents the ingress of water and pressure of water column in the underground structures.
Water Tanks and Reservoirs: Ascertains that all constructions dealing with water storage are tight proof. Balconies and Terraces: Acts as a barrier to liquid and water in particular in order to reduce their entry into the vehicle’s body.
Bathrooms and Kitchens: Membrane system closes in walls and floors to ensure that water does not penetrate in areas such as wash rooms.
Swimming Pools: Responsible for the pool structure to be leak proof.

Advantages of Cementitious Waterproofing :

Durability: Offers long term protection against the ingress of water in structures and other constructions’ works.
Ease of Application: can be applied by means of brushes rollers for touch and spray equipment for non touched system.
Cost-Effective: In general they are relatively cheaper considering other processes of maintaining the waterproofing of structures.
Compatibility: Is versatile in that can be applied on any surface including; Concrete surfaces, masonry and bricks among others.

Disadvantages of Cementitious Waterproofin :

Limited Flexibility: Buildings or structures that are subjected to extensive movement may not suit the use of cementitious membranes and rigid solutions to waterproofing.

Surface Preparation: It removes the acquisition of surface preparation needed where the bond will be between the tiling material and the coating applied. Curing Time: May take a bit of more time to set down and it also might take some time before is completely water proof.

Application Process :

Surface Preparation: To get rid of previous material deposits, incubate levels of dust, dirt, oil or grease and other loose materials to scrub to get an even base for the next processes. If there are any, sand any gaps or other damages that you had to leave while pulling the laminate.

Mixing: At other times, there are special instructions from the cementitious producer as to how the cementitious material should be prepared. Remember that the mix is uniform, do not have lumps in the mix to give a better texture.
Application: The mixture can be applied through brush, rolling equipment or spraying equipment in case of use. It is requisite to put the same force and the VSD to be of equal thickness.
Curing: Believed the used applied Waterproofing layer to cure for the recommended time before exposing to water or loads.

Maintenance :

The daily check to ascertain whether there are any damages or cracks, which would require repairs to be made.
On areas that have been treated before, or areas that require a second or a third coat for a waterproofing layer.
Cementitious waterproofing one of the most effective ways of protecting various structures against water and is used in many constructions. Ref: HDB Roof Ceiling Works
