Just a few of our satisfied clients
Chris F.
Wieser Concrete produces a solid low-profile holding tank. Due to the elevation of Lake Michigan, the depth to groundwater, and the flowing sand conditions, the low profile tank was preferred.
Dan F.
Magney has worked with Wieser in the past and is familiar with Wieser's expertise on precast structures and storage tanks. For this project, the engineers intended the backwash tanks to be precast concrete.
Nelson B.
Contech has been a partner with Wieser for over 15 years. We have done countless successful projects together and this one is no different. We had a demanding contractor and schedule for this project and we knew Wieser would value that as well as produce a high-quality product as usual.
Leo S.
I have used Wieser for virtually all of my non-architectural work for decades, which is why we chose them for this project.
Chris C.
This project will enable us to provide full-scale experiential learning opportunities for our students to better prepare them for the workforce.
Denelle K.
The shop drawings provided by Wieser were drawn to professional-grade and allowed us to easily understand and relay the information needed to our customer. Wieser has provided precast storage vaults/units for some exceptionally large projects, so we were confident that they were able to provide what was required.
Fred J.
The installation went great, very good driver. Thank you for the military discount. We hope we never have to use the shelter, but now we have peace of mind.
Ashley P.
We have been very satisfied with Wieser Concrete's efficient production efforts over the last several years especially during the tight schedule demands of customers. We promoted the Komro/Wieser Concrete design to the engineer which got easy approval at the State level.
Tony B.
Precast provides the flexibility and customization needed which are needed in our designs. Wieser Concrete provides amazing support and the highest quality control in the industry. They stand by their product and are true advocates for the onsite wastewater industry.
Dan A.
We chose Wieser Concrete for this project because of their reputation to provide the best product possible. The product that we received for this project was excellent. The fit and finish were everything that we thought they would be. The crew that installed the panels was professional and got the job done in a timely manner.
Tom L.
We chose Wieser Concrete for the job due to their ability to perform the work, pricing, and expectation of quality and service.
Tom B.
Aqua Tech has used Wieser tanks on other projects and has determined their quality is well above any other precast tank manufacturer. We use them on any project we can because of this. The quality of workmanship and materials as well as the support from the staff and company as a whole makes Wieser Concrete unique! Wieser is willing to customize any of their tanks in order to fit our tank needs.
