Waterproofing Membrane is an important part of keeping a basement or foundation dry and in good condition. It helps in preventing leaking concrete slabs, sagging foundations and mould formation.

There are various types of waterproofing membranes available on the market. Some of them are liquid applied and others are pre-formed sheets.

Bituminous Waterproofing Membrane

One of the most popular waterproofing materials is bituminous membrane. These are made from asphalt, polymers and tackifiers. They have a layer of adhesive on top and the bottom is coated with a polymer film.

These materials are also available as self-adhesive membranes. These are adhered to a surface with a hot tar-based adhesive and are then joined with another layer of waterproof membrane. They can also be used as jointing membranes by melting the edges of the sheet with a torch flame source.

APP (Atactic Polypropylene) Waterproofing Membrane

APP membranes are highly durable and largely preferred by contractors for safeguarding surfaces against leakage. They offer high tensile strength which ensures that they don't break under tension.

Flexibility of the material is also an important factor to consider. APP membranes can survive storms and harsh atmospheric conditions with no cracks or dents.

Sealing and Repair Services

A good waterproofing service will keep up with regular maintenance and inspections of the waterproofing membranes installed on buildings. This will help prevent recurring water damage and can also help verify that the installation was completed properly. Checking for signs of deterioration like staining and cracks can help identify potential issues with the membrane before they cause structural damage.
