About us

Owner, Bob Kost has worked in the concrete construction and restoration industry since 1977. He began installing large residential foundations and drain tile systems in Kane and Du Page counties. The company he worked for branched off into the concrete restoration and waterproofing industry. Working with and developing knowledge using specialty products which were used in restoring structures in paper mills, water treatment plants and manufacturing facilities.

My experience using polymer repair mortars, epoxy and urethane coatings, caulk sealants and waterproof membranes has equipt me to find “solutions for every concrete installation and repair” , which has become the companies motto.

After incorporating in 1984 I have personally repaired over 5000 residential concrete foundations in the Chicagoland area using epoxy resins for structural repairs and chemical foam grout for non- structural waterproofing repairs. All of our foundation repairs come with a life-time warranty.

One of my most important functions as a business owner is to provide our customers with quality control necessary to complete each job. That’s why on every job we do I’m present to insure that your project will be completed as specified and will be performed in a workman like manner, meeting or exceeding local and state codes and requirements.

That is why in part we have maintained an A+ rating with the Better Business Bureau! We value that rating had have received their Complaint Free Award in 2009. Home waterproofing and concrete projects in and around your home require a professional company and staff with the experience you deserve. Whether your thinking of a new driveway, a room addition foundation, drain tile system or just have a leaky foundation, Kost Services, Inc. is the company for you.
