Customer Service

Over the years, we have built great relationships with hundreds of satisfied repeat customers. We treat all our customers fairly. As contractors, one of your most important considerations is that you’re given the opportunity to bid on a job coming in, and have the same opportunity as your competitor. We treat every client with the same fair price no matter how large or small your company or whether you’re a new or old customer.

Crane Truck & Delivery Service

Not every pre-cast concrete company offers delivery and installation, but we do. With the use of our own certified crane operators, we will save you time and money. Offering 103 combined years’ experience, our certified crew works with your team for optimal results. Our trucks are strong and have a reach that fits most jobs.

Decades of Experience

Our company has been in the pre-casting business for over 40 years. Thanks to our tried-and-true production methods, we use techniques not seen in large manufacturing sites. This approach to pre-casting allows us to easily and quickly modify our septic tanks and other concrete products for special customer requests.

Environmentally Conscious

As a family-owned company, we’re very aware of how our business affects the environment. We have minimal waste, we recycle our water, and we make sure any leftover product is used.

Guaranteed Products

We have a huge stock on hand, but we also custom design products and build as needed. This helps us serve our clients to the best of our ability. Most importantly, we stand behind each of our pre-casted products. If there is any problem with your product, we will replace it. Our team won’t abandon you should something go wrong, whether it’s a flaw in the product or an issue caused by the installation process. We work with you to solve the problem.

Street Light Bases

Illuminate streets, parking lots, and walkways with streetlights fashioned with our sturdy pre-casted concrete bases. We stock a variety of MMCD & MoTH Bases with the ability to adapt to any custom configuration. We also have the equipment capable of lifting, shipping, and placing any of our bases, which can help save our customer’s time and money. Just send us your specs, and we can give you a quote for your streetlight bases.
