Concrete Sealants, Inc. is founded on the principle of serving others. Our founder, Bob Haman Sr., had a credo that he often repeated, “Who do we work for? The Customer!”. However, serving the customer is not where Bob’s service stopped. His service extended to his employees as well, fostering a safe workplace and creating an environment where management listens to the ideas of every employee. In this regard, Mr. Haman was ahead of his time in establishing a lean manufacturing culture within his company by encouraging internal growth and continual improvement of our manufacturing process. Additionally, he mentored and groomed a staff that makes his credo their own. This investment in others is a perfect example of the service minded life Mr. Haman lived, and is a quality he passed on to his family – who still own and operate ConSeal to this day by following that same principle and living Bob’s credo:
“Who do we work for? The Customer!


ConSeal leads the sealant industry through innovation, technical expertise and customer support.

Since our founding in 1970, we’ve proudly served our producers and end users with a full line of top-quality products. Today, we are widely recognized as a first-line extruder/ compounder of sealants, wraps, coatings, primers, mastics, lubricants and form release agents. 

Our ongoing commitment to the development of (often revolutionary) new products, coupled with our excellent technical and customer service support, have made us the one company users look to for reliable, first-rate solutions to their sealant problems.

A History of Firsts

ConSeal is the first sealant manufacturer to work side-by-side with concrete producers in their plants and on their jobsites to see first-hand how even slight changes in product cross-sections and/or chemistry can improve their sealing properties and their value to the user. Today, this continuing field experience keeps us close to our customers and at the very forefront of new industry developments.  


At ConSeal we get you what you need, where you need it, when you need it there. Each of our U.S., Canada, and overseas warehouses carries an extensive inventory of our materials and sizes, which are most commonly requested. If you need sealant fast, we can help.
