Your Trusted Concrete Flatwork Business for Over 19 Years

Founder Doug Ortmann grew up in the concrete flatwork business and has worked with concrete since 1991. The Ortmanns’ officially became business owners on Aug. 25, 2003, with Ortmann Concrete Inc. OCI is an expanding business based out of Arnold, MO. We serve property management and utility companies, commercial contractors as well as residential clients throughout the St. Louis Metro Area. Our attention to detail, communication skills, and quality craftsmanship are what set OCI apart from other concrete contractors.

SealGreen Authorized Resaler

SealGreen specializes in manufacturing concrete sealers and concrete cleaners that are simple to apply and will protect the concrete for many years before re-application is required.

Mike and Connie Hernandez, owners of ReUse Concrete Sealing Specialists, LLC, had spent many years in business specializing in cleaning and sealing concrete for industrial, commercial and residential clients. Throughout their trial and error process of using many different products and techniques, they realized there was a need for higher quality products along with more efficient cleaning and installation practices. After much research, formulation and experimentation they developed the SealGreen product line that finally meets their stringent requirements.

SealGreen has gotten away from the standard toxic, solvent based products commonly available to the contractors and homeowners today. SealGreen manufactures an environmentally friendly, EPA approved, water based solution to properly care for and maintain concrete surfaces. These products also come in concentrate form, not only saving on shipping costs and packaging materials, but provides easy to use instructions for mixing and application. The chemistry technology behind SealGreen’s products has been thoroughly studied and formulated to bring only the best products to market for you the consumer.

SealGreen prides themselves in their knowledge and experience and encourages you to contact them with any questions or comments regarding their products or usage.

Client Testimonials

Our original driveway was crumbling to pieces. We put off the replacement for a long time thinking that a new driveway was not where we wanted to put our money. Now that we have our new driveway (and sidewalk and steps) from Ortmann Concrete, I cannot believe how much a difference it has made. We feel like it has added value to our house and is an investment we should have done earlier. We actually had to do some landscaping to make our yard look as good as our driveway.

Ortmann Concrete did my countertops for my new kitchen and I was amazed at the quality and professionalism. Doug designed the countertops to match my back splash and redesigned the bar to give it a new look. I would highly recommend this company to anyone who wants quality work at a great price. Thank you for your work.
Chris Nordin
Ortmann Concrete did a fantastic and high-quality job on our backyard outdoor kitchen project. OCI lined up all the work and delivered as promised at a reasonable price without ever coming back and needing to add costs. Was always responsive to questions via phone or text. The countertops; fireplace; and stone work always receive lavish comments and praise from anyone that visits our home. You will not go wrong by talking with and/or hiring OCI to do any job needed. Very family-oriented business.

We are so happy with our new patio and fire pit area just finished by Ortmann Concrete. Doug helped us design a sitting wall around the fire pit area that turned out amazing. The owners, as well as all the work crew were so great to work with. They had to deal with record rainfall and record flooding issues, and worked so hard to finish the job as quickly as they could. We could not be more pleased with the outcome.

Great! Efficient. Friendly. Transparent. I had no idea what to expect, as I have never had concrete repaired prior to this. I contacted several different places to discuss lifting, repairing, or replacing the concrete. In the end, Ortmann offered a great price and I could not be happier! They communicated well with me the whole way through and I am so happy with the final product. They even worked with me to find someone to replace the hand rail on the front stairs, even though they do not do

We were on a tight schedule to try and get this in prior to school beginning August 17th. It could not have gone any smoother from the initial call, consult and crew coming out…in fact, they even came out on a Saturday since Mother Nature was not cooperating! This is a great company to work with! I would highly recommend them and am planning on calling them on a home project next year!
