Membrane Waterproofing

A waterproofing membrane is a layer of water-tight material that is laid onto a surface to prevent water leaks or damage. Waterproofing membranes generally consist of liquid applied or pre-formed sheets. They can be adhered to or installed around the foundations (like a structural slab) to prevent water penetration.

One of the best ways you can ensure your customer’s building stays protected over time is by having a waterproof foundation. A high-quality foundation waterproofing membrane serves as the all-important barrier between the concrete and the surrounding earth. It helps prevent water infiltration and can even resist harmful contaminants from entering the structure.

Types of Membrane Waterproofing:

Bituminous Membranes:

•   Asphalt-based membranes: Widely used, affordable, and offer good waterproofing properties.
•   Modified bitumen membranes: More flexible and resistant to cracking than asphalt membranes.

EPDM Membranes:

•   Synthetic rubber membranes: Highly flexible, durable, and resistant to UV radiation.
•   Used in various applications, including roofs, ponds, and basements.

TPO Membranes:

•   Thermoplastic polyolefin membranes: Highly reflective, energy-efficient, and resistant to chemicals and punctures.
•   Popular choice for commercial buildings and flat roofs.

PVC Membranes:

•   Polyvinyl chloride membranes: Durable, flexible, and resistant to chemicals and punctures.
•   Widely used in waterproofing roofs, basements, and swimming pools.

Liquid-applied membranes:

•   Spray-applied or brush-applied coatings: Offer seamless protection and conform to irregular surfaces.
•   Ideal for waterproofing balconies, decks, and other complex shapes.

Application of waterproofing membranes:

Regardless of the scale, size, location or type of building, waterproofing membranes are an essential component necessary to protect the building’s structural integrity and its inhabitants. Its application areas include:

•   Ease of use Tanking/Basements
•   Flat Roofs (including Green Roofs)
•   Plant rooms
•   Podiums and balconies
•   Retaining walls
•   Garden beds and planter boxes
•   Concrete water tanks
•   Containment and bunded areas
