Poly Dike With Flexible Liner

POLY DIKE wall containment systems are used in place of concrete as secondary containment around storage tanks. POLY DIKE walls vary in height from 18" to 36" in 6" increments. Usually, a system is custom designed for each application, but sections and corners may be purchased for stock like the POLY CURB. The POLY DIKE wall containment system may be used as a stand-alone wall system, in conjunction with a fiberglass floor lamination, or with a fabric liner. POLY DIKE applications are similar to POLY CURB applications, but where greater capacities or barrier heights are required.

Construction and Capabilities of the Poly Dike™ Dike Wall Containment System

Our POLY DIKE wall containment system is composed of truncated triangular structures manufactured of various thicknesses of fiberglass based on wall height. POLY DIKE'S unique design allows both sides of the wall to share equally in load bearing.

POLY DIKE is flexible. The modular design coupled with wall heights varying from 12" to 30" allows flexible use of floor space to meet capacity requirements. Note that when determining system size the base of the POLY DIKE wall varies in width from approximately 12" to 24" based on wall height. POLY DIKE systems may be used in a number of ways. The three most common ways a POLY DIKE wall containment system is used are: (1) Bolted and sealed to a concrete pad, (2) Bolted and sealed to a concrete pad with fiberglass floor lamination, or (3) Bolted together and used with a flexible liner.

(1) Sealed to a concrete pad
POLY DIKE secondary containment walls may be sealed to a concrete pad by one of two methods:

  • Polystar technicians or the customer can seal the walls along the base flange with caulk sealant;
  • Polystar technicians can chemically bond the base flange to the concrete floor using fiberglass materials.

(2) In conjunction with a fiberglass laminate bonded to a concrete pad
This system is chemically resistant and monolithic. It also is completely non-porous, as a fiberglass lamination is bonded to the concrete floor and to the base of the POLY DIKE walls. Also note that this system is particularly appropriate for areas which include plumbing, equipment, or tank supports, as the fiberglass lamination may be bonded over or around these obstructions if required. Polystar technicians always install this system.

(3) In conjunction with a fabric liner
A one-piece liner may be used to cover the floor. The liner is large enough to go up and over the POLY-DIKE wall containment, so that it can be secured to the wall tops with fiberglass "clips".

Securing the clips to the wall tops with self-tapping screws holds the liner in place. For aesthetics, the liner may be trimmed along the outside edge behind the "clip".

Limited site preparation, no excavation, fast, clean installation, immediate use, non-porous design, superior chemical resistance and portability are only some of the many POLY DIKE wall containment and secondary containment advantages.
