Poly Dike - Dike Wall Containment System

Our POLY DIKE wall containment system is composed of truncated triangular fiberglass structures manufactured of various thicknesses 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 27″ based on wall height.

The most common ways a POLY DIKE wall containment system is used are: (1) Bolted and sealed to a concrete pad, or (2) 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:

• The customer can seal the walls along the base flange with concrete fasteners and caulk sealant;
• The customer can chemically bond the base flange to the concrete floor.

This system is chemically resistant, non-porous and monolithic. This system is particularly appropriate for areas which include plumbing, equipment, or tank supports and may be bonded over or around these obstructions if required.

(2) 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 it can be secured to the wall tops with fiberglass “liner locks.”

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 “liner lock”.

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.

Poly Dike walls are truncated triangular structures manufactured from either 3/16” (5mm) or ¼” (6mm) thick fiberglass based on wall height. Poly dike’s unique design allows both sides of the wall to share equally in load bearing.

Poly Dike’s modular design, coupled with wall heights that vary from 12” (30.5cm) to 36” (91.4cm), allow flexible use of surface area to meet area and capacity requirements. Note, when determining the system size, the width of the Poly Dike walls should be taken into account. The Poly Dike wall varies in width from 14” (35.6cm) to 24” (61cm) based on wall height. Poly Dike systems may be may be installed in several ways to cover a wide variety of applications. The three most common methods of installation are:

Sealed to a concrete pad
The customer or his selected contractor can seal the walls to a concrete pad along the base flange with gasket, caulk or fiberglass materials.

In conjunction with a floor coating
The customer or his selected contractor can seal the floor and the Poly Dike wall bases with a floor coating.

In conjunction with a fabric liner
A one-piece fabric liner may be used to cover the floor and Poly Dike walls. The liner must be large enough to go over the Poly Dike walls, so that it can be secured to the wall top with fiberglass wall clips. Securing the wall clips with self-tapping screws holds the liner in place. For aesthetics, the liner may be trimmed along the outside edge behind the wall clip.

To secure the system to the substrate, pre-drill holes every foot along both horizontal mounting flanges for insertion of fasteners (concrete fasteners for a concrete substrate, long spikes for other substrates).
Key Poly Dike Benefits:

• No Footers Needed
• Fast, Clean Installation
• Superior Corrosion Resistance – Even To High Acid Concentrations
• Flexible Use In Cold, Hot, Or Moist Environments
• No Gapping Or Cracking
• Easy To Add To Or Relocate
• Custom System Design

PURPOSE: POLY DIKE is designed to be used as secondary containment for liquid and solid products that are considered to be harmful to the environment if leaked from their primary containment device. Applications include chemical storage tanks, hazardous material work areas, process waste treatment sites, rainwater runoff diking or similar applications.

SCOPE: This product specification covers materials, construction and workmanship, physical properties, chemical resistance and methods of testing.

MATERIAL: Premium fiberglass mat and industrial grade isophthalic or vinyl ester resin as manufactured by Ashland Chemical or equivalent are used in construction. A gel coat surface resin of equal chemical resistance, with the additive antimony trioxide for flame retardance and U.V. protection is included. The flame spread rating is Class II. Tested by ASTM E-84.
