Construction Barriers and Tank Containment

A light-weight, easy to install modular wall system for construction projects and secondary tank containment.

Portable Construction Barricades, Safety Barriers & Tank Containment Systems

Searching for a light weight, easy to install modular wall system for construction projects and secondary containment. Featuring a  portable polyethylene design,  the Poly Dike MPE is the perfect choice for any number of small- to large-scale building projects.

The Advantage of the POLY Dike MPE include:

  • When used in conjunction with a fabric liner, provides low cost secondary containment for moderate sized tanks and tank farms
  • When used as modular pieces, forms portable construction barricades & plastic safety barriers for small to large-scale building projects.

The primary components of each Poly Dike MPE System are a number of 4’ long x 3’ (91.4cm) tall straight and 8’ long x 3’ tall corner wall struts. Using these modular building blocks, we have created a variety of system sizes for capacities from 1,000 to 515,000 gallons in regards to storage tank secondary containment.

The Poly Dike MPE stores compactly, as the walls nest and stack together when not in use. The light weight (40 pounds) of each wall strut and the modular design allow assembly of an entire system by as few as two people in containment or construction scenarios. In addition, all components needed to secure the wall struts together are integral to the struts themselves, assuring parts are not misplaced. Each finger lock joint is secured with a Locking Connector integral to the wall strut. This joining system ensures high structural strength with little installation effort.

After all of the wall struts are in position, the entire system is tied together with a heavy duty, woven nylon web Harness Assembly. On all four sides of the Harness Assembly are pigtails ending in solid steel D rings. These D rings slide into custom designed slots in the wall struts, where they are anchored in place by the Locking Connector. Stretching the Harness assembly taut creates a unified, super-strong structure. After set up of the Poly Dike MPE is complete, a flexible liner is rolled out and draped over the wall struts. Securing the liner in place with our innovative Liner Bar Locks finishes set up of your non-porous spill containment system.

When a catastrophic tank failure occurs, a powerful wave hits one side of the system. Structural support from both the weight of the still partially filled tank on the Harness Assembly and the Harness Assembly’s locked steel D rings on the opposite wall allow the system to withstand the wave’s force without movement. Further the uniquely angled wall strut design forces any flow back into the system, not over the walls, to prevent fluid loss.

In construction and building scenarios, the Poly Dike MPE forms strong and very visible safety barriers to keep pedestrians and auto traffic away from the actual work zone. Lightweight nature of each dike component enables the assembly of encircling construction barricades or single-line blockade barriers to keep construction zones safe and clear of bystander traffic.

The Poly Dike MPE is not anchored to the substrate. This feature means the Poly Dike MPE is ideal for long term or temporary use in parking lots or on concrete areas.

The above installation description is for new tank applications, or for where tanks can be lifted for liner installation. However, the Poly Dike MPE may also provide secondary containment for existing tanks located on a concrete substrate. In this scenario, a liner “skirt” covers the wall struts and is locked to the wall struts with Liner Bar locks as described above. This liner ends approximately two feet (61cm) beyond the base of the struts inside of the containment area. This end of the liner is sealed all around to the concrete with gasket. Steel compression plates are mechanically fastened to the sandwich of concrete, gasket and liner to compete the installation. Note that in this application, the existing concrete substrate will be most of the floor of the completed containment area.

In outdoor building and construction scenarios of all types, the Poly Dike MPE is light enough to be handled by a crew of two yet effective for keeping large crowds at a safe distance. The stackability of the Poly Dike MPE ensures maximum efficiency for companies conserving space.
