Waterproofing is very important for every home or building. It protects your property from water damage, mold, and leaks. If you live in Bronx, NY, you know how rain, snow, and humidity can cause serious problems. That’s why you need strong and reliable waterproofing materials.
In this article, we will share the top 10 waterproofing materials that many contractors in the Bronx use and trust. These materials are highly rated by professionals, including experts from Legacy Constructions Corp. INC., a trusted name for waterproofing service in Bronx NY. We will explain each material in simple words so you can understand what’s best for your home or business.
1. Liquid Waterproofing Membrane
Liquid waterproofing is a flexible and easy-to-apply material. It is like thick paint that you roll or spray onto a surface. Once it dries, it forms a rubber-like coating that blocks water.
It can reach small corners and cracks.
It works well on roofs and balconies.
It stays flexible even after drying, so it won’t crack easily.
2. Bituminous Membrane
Bituminous membrane is often used on flat roofs. It comes in rolls and is either self-adhesive or installed with heat. This material is made from asphalt, which is great at stopping water.
Very strong and long-lasting.
Resists water even during heavy rain.
Good for commercial and residential use.
3. Cementitious Waterproofing
This material is one of the easiest to use. It is a cement-based mix that is applied with a brush. It’s best for areas like bathrooms, basements, and water tanks.
Easy to apply, just like paint.
Very good for places with water exposure.
Bonds well with concrete surfaces.
Legacy Constructions Corp INC. often uses cementitious waterproofing for internal walls and basement areas.

Polyurethane is a liquid sealant that creates a seamless waterproof barrier. It is often used on roofs, terraces, and balconies.
Why it stands out:
High resistance to water and chemicals.
Fills cracks easily.
Long-lasting and smooth finish.
Many experts offering waterproofing service in Bronx NY recommend this for tough weather conditions.
5. EPDM Rubber

What makes it great:

Reflects sunlight, helping with energy savings.
