Landmarks for their communities
Composite elevated tanks have another role beyond their function as an essential element in the water system infrastructure. Their visibility helps define their communities, and their aesthetic quality is highly dependent on the precision and attention to detail in the construction process.
The combination of Landmark's vertical segmental pour process and QP-1 certified coatings expertise set and deliver the highest standards of appearance and functional quality, on the reinforced concrete pedestal and the welded steel tank. Learn more about these differences by watching the video and reading the article provided on this page.
Raising the bar
“Uniform color, an absence of defects, and aligned and even surfaces”
--ACI standard 303R-04.
Architectural concrete is the standard for all Landmark projects, with poured surfaces that rival pre-cast in their precision and consistency—a function of concrete mix design, placement rate, and forms—proven in more than 10,000 wall placements and 500,000 cubic yards poured. This standard distinguishes the quality of Landmark’s support pedestals, the defining feature of the composite elevated tank.
Vertical segmented pour process
The key to meeting all structural requirements while setting new aesthetic standards is Landmark’s process of rapidly pouring carefully monitored concrete from a single truck into vertically bulkheaded wall segments, using robust forms with precise adjustment and complete sealing. This highly refined system facilitates the speed required to avoid a differential set and resulting pour lines, as well as the quality control measures that ensure predictable results.
As each vertical segment is poured, the bulkhead adjoining the last pour is pulled, and all material vibrated for consistency and the removal of air pockets. Once the wall has set, the forms jump up to the next level, lap and attach securely to the wall below, and are laser-aligned to exact plumb and radius, ensuring precise dimensions and tolerances over the full height of the pedestal. The result is the trademark grid pattern and clean, consistent surface quality that complements its environment, regardless of location—and costs no more than a basic, utilitarian approach.

QP-1 certified coatings expertise
Landmark achieves an equally high standard on the steel tank, with surface preparation and specialty coatings expertise recognized by the Society for Protective Coatings’ coveted QP-1 certification, validating processes and performance. Landmark’s coating experts can create and execute virtually any type of tank graphic, and work at ground level for optimum precision, safety and environmental protection.
