Water Proofing

Here’s a more detailed explanation:

What it does:

Waterproofing creates a shield against water damage by preventing water from entering a structure. This is crucial for maintaining the integrity of buildings, preventing costly repairs, and ensuring a healthy environment.

Structural Integrity: Prevents water damage to foundations, walls, and roofs, which can lead to cracking and degradation.

Health & Hygiene: Inhibits the growth of mold and mildew, improving indoor air quality and occupant health.

Durability: Extends the lifespan of the building by protecting materials from moisture-related deterioration.

Pest Control: Reduces moisture, making the building less attractive to pests.

Saves Money: Waterproofing can prevent costly repairs and renovations that may be needed due to water damage.

Waterproofing is commonly applied to:

Roofs & Terraces: Protecting against rain and snow.

Basements: Preventing water from seeping in from the ground.

Bathrooms and Kitchens: Protecting against leaks and spills.

Walls: Preventing moisture from penetrating through exterior walls.

Foundations: Ensuring a dry and stable base for the building.

Underground and over head water tanks.

Swimming Pool

Flower Bed

Underground ducts

How Water Can Penetrate Concrete Structure:

How it’s done:

Waterproofing involves using a variety of materials and techniques, including:

Membranes: Flexible sheets that create a waterproof barrier.

Coatings: Liquid or paste-like materials that are applied to surfaces to create a waterproof layer.

Sealants: Materials used to fill gaps and cracks, preventing water from entering.

Type of Waterproofing:

1. Injection Grouting: Used for treating cracks, leaks, and creating barriers in basements and tunnels by injecting materials into structural fissures.

Disadvantages:

Limited Scope: Injection grouting is an effective method to address specific points of water intrusion in concrete and masonry, such as cracks and voids, but it is not a comprehensive waterproofing solution because it doesn’t protect against water permeating through the solid concrete itself or at large structural interfaces.

Material Porosity: Some grout materials, like open-cell foams, are more porous and may offer only temporary solutions for larger or continuous water problems.

Structural Suitability: The method is most effective on solid walls and may not be suitable for structures with cavities, as the injected material can be lost within the voids, failing to create a proper barrier.

2. Liquid-applied membranes: The liquid membrane consists of a primer coat and two topcoats.

The application of the coatings is by spray, roller, or trowel.

The liquid layer is thin and offers more flexibility than the cementitious types of waterproofing.

The liquid cures into a rubbery coating on the wall. The elongation properties of the coat can reach as high as 600%.

The durability of the waterproofing coating depends on what type of polymer the manufacturer used for the making of the liquid waterproofing.

These are applied to create a seamless, flexible barrier and are ideal for versatile and complex shapes and areas with movement.

Materials: Acrylic, polyurethane (PU), Polyurea.

Application: Sprayed or rolled onto surfaces to form a seamless membran.
