Product knowledge, wide selection, competitive prices.  The staff at Thoro System has an average 25 years experience.  We
eagerly look forward to the unique challenges and problems of your particular project, no matter how large or small.

You would be hard pressed to find another store with the selection you will find at Thoro.  You will find in stock three different
types of caulks in over 120 different colors, 34 colors of stucco in stock, over 20 clear water repellents or sealers; 20+ repair
mortars; plus epoxies, waterproof decorative coatings,  paints, tools and much more.  For a list of all our product categories

A recent price shopping comparison with two local national building material chains confirmed Thoro’s claims that they are more
than competitive. Of further interest, Thoro System specializes in the sale of industrial grade products which many times are
superior to the consumer grade sold by the chains.

Another large benefit to anyone outside our local Delaware County Pennsylvania area is the availability of our knowledge and
products from a large network of dealers we service. Our Dealer resale operations are the largest part of our business.

We welcome your calls and would be happy to recommend a dealer in your geographic area to locally serve you.

For over 80 years, Thoro System Waterproofing Inc., a wholesale/retail supplier of waterproofing and restoration materials for
concrete and masonry, has been serving dealers, contractors and D-I-Y’s in Eastern PA, South Jersey and Delaware.

Starting in a one-car garage in Drexel Hill PA in 1936 and moving from there to Springfield in 1947, Thoro System quickly
gained the trust and following of dealers, contractors and homeowners alike.  In 1989, Thoro System Waterproofing Inc. was
forced to move out of Springfield because of space limitations of their existing facility, and chose to relocate in Folcroft.

Currently in a 22,000 square foot facility located in the lower level of the ‘Delcroft Shopping Center’, Thoro System has greatly
expanded its product line while still specializing in products to waterproof, restore, protect and beautify concrete and masonry.

“Buy where the professionals buy” is the challenge we offer the local D-I-Y!  With more and more cost conscious homeowners
wanting to tackle their own  waterproofing and masonry repair projects there is an ever increasing need for professional advice
and step-by-step help … something most national chain-store building material and big box stores can not provide.
