Waterproofing Materials Products

Sometimes you need the right waterproofing materials to keep your project area clear of water while under construction. When you need to keep the construction site dry, we have the right poly sheeting and waterproofing materials for your specific needs.

At 9 Brothers Building Supply, we offer a wide variety of construction, masonry, and building products perfect for any project. Our waterproofing materials will help keep your construction project dry when you're in the middle of the work.

Poly Sheeting

With the right poly sheeting, you can keep your project from becoming ruined due to rain. It comes in a lightweight roll with thicknesses from 4 to 10 mm and widths up to 20 feet. Our rolls are up to 100 feet long, as well.

When you choose poly sheeting or polyethylene sheeting film, you get an economical option for waterproofing your construction site. If you need low-cost waterproofing materials for your job site, we've got the right options for your specific needs.

With this type of waterproofing material, you get plastic protection for your construction site. It can be used as a vapor retarder, in flooring projects, for countertop protection, for window filming, to cover building materials, to seal off rooms, and for even more.

Even if you don't need to protect your construction site, you can use poly sheeting to protect one room of a project while working on another. It can also be used to protect flooring, countertops, and so much more.

MEL-DRAIN Rolls

Along with poly sheeting, we also offer W.R. Meadows MEL-Train 5035 Rolls. These rolls are available in 48-inch by 50-feet and offer a great choice for your job site. This type of product will help to prevent fine soils from getting into a drainage channel, while also allowing moisture to pass through. It can be used to help provide protection when you need it for drainage applications.

Depending on your job site and what you need exactly, we offer the right products for your needs. Our two locations in the NYC and Long Island area offer waterproofing materials in stock. You can pick up the products you need for your construction site at our Brentwood or Riverhead locations and one of our staff members will be happy to help you.
