Advancements in the Waterproofing Industry

Water leakage is a serious problem that can arise in any construction, and traditional waterproofing is only a short-term solution, which with the passage of time may get damaged. The way to correct waterproofing is addressing waterproofing problems with a positive approach using advanced technology.

Waterproofing is one of the most important criteria considered in the construction industry to prevent leakage, dampness etc. problems in the structures and extend their life. Today, latest advanced waterproofing technologies are being used across the globe. In a country with seasonal rainfall, effective waterproofing is a must.

Traditional Waterproofing Techniques

Traditional waterproofing comes with certain limitations, and hence modern waterproofing techniques are replacing it. Following are listed some conventional waterproofing types:

Admixtures: Mineral admixtures such as lime, fly-ash, silica and chemical ones like plasticisers, water reducers and shrinkage reducing admixtures are all used for specific purposes. This addition helps to minimise water content in the mix making the concrete dense, compact and durable for leak-free structures.

Film Forming Membrane: This is a liquid applied waterproofing coating.

Surfacing: Asphalt, concrete, polymer concrete, polymer modified mortar, epoxy mortar etc. are used as a cover over concrete for waterproofing in this method.

Sealants: Joints are an essential part of the structures, all of which are sealed with proper sealants.

Impregnation: In this method, a solution is instilled into the pore structure by three different actions: hydrophobic, partial filling and filling.

The conventional waterproofing methods like brickbat coba, lime concrete are still in use but slowly becoming obsolete, while the use of a polymeric membrane as a waterproofing coating is gaining popularity because of its abundance. The reinforcement of polymers at the core serve following purposes:

  • Increases the tensile strength of the structure
  • Enhances elongation capabilities
  • Acts as a fire protection enhancement
  • Bridges substrate gaps

Latest Advancements in Waterproofing Technology

Some of the latest advancements in waterproofing technology are listed below:

Thermoplastic Membranes: Synthetic roofing membrane based on thermoplastic and thermoset technology is the newest addition in waterproofing membranes.

Gel Technology: A gel expands and adheres to any leaking area when contacted with water. The gel is made up of a polymer resin of rubberised asphalt. It finds out leaks and expands to repair damages.

Nanotechnology: Eco-friendly Organo-Silicon products can be used to waterproof almost all the kinds of building materials. The service life of this materials is 20 to 30 years at a very economical cost.
