Because the product is asphalt-based it adheres to the wall as tenaciously as tar, but its rubbery nature allows it to stretch to bridge the minor shrinkage and expansion cracks typical in poured concrete walls. It carries a limited lifetime warranty that can be transferred to future owners of the home, adding both value and protection.


If you are a contractor who has used our waterproofing in the past, you can rest assured that your customers will be receiving the same great performance and the same great warranty coverage. With the advent of Centurion, we were presented with the opportunity to upgrade to a water-based product with out sacrificing the convenience of a membrane only product or the consumer confidence and marketability of a transferable limited lifetime warranty.


Our applicators are manufacturer certified and, as always, all warranty issues are handled in-house.

With next-day service and a service area covering Southeastern Pennsylvania, South and Central New Jersey and Northern Delaware, we will be there when you need us.

J.M. Pereira & Sons, Inc. has been in the waterproofing business for over 30 years. In keeping with our determination to provide the best products and services to our customers, we use a waterproofing product called Centurion by Tremco®.                                             

Centurion is a polymerized-asphalt waterproofing membrane that is sprayed onto the exterior sub-grade walls of your new home’s basement or crawlspace. The product dries forming a  thick rubbery layer designed to keep moisture from entering through the walls of the structure.
