Thoro System Waterproofing

For 75 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.
