Liquid Storage You Can Count On

Dome Technology has brought a tank to the market that will save municipalities significant money based on an efficient building method with less waste—a win for taxpayers and local governments alike.

Dome Technology’s AWWA D1150 tank is built with this process: The foundation is established, and an airform fabricated in the exact shape of the finished tank is attached to the foundation and inflated with high-power fans. Concrete is sprayed directly onto the airform’s interior to form a vertical stem wall and the low-profile domed roof. Post-tensioning cables are attached to the stem wall, along with typical reinforcing vertical and horizontal rebar. Concrete is then sprayed to embed the cables.

After the concrete cures, the tank is disinfected. A polyurea coating is applied to the entire interior, and the domed roof is closed up with a hatch and ladder up the side for access.
