A bunded area is a critical component of any compliant wash bay system. It’s designed to contain spills, leaks, and contaminated wash water, preventing pollution of surrounding land and waterways.

At Washbay Specialists, every wash bay we design and construct includes high-quality bunding solutions tailored to your site and environmental requirements.

What Is a Bund?

A bund is an impervious wall or embankment built around a wash bay or liquid storage area. It acts as a containment barrier in the event of a spill, leak, or washdown overflow — creating a controlled zone known as a bunded area.

Bunds are essential for any site where liquids are handled, including:

• Wash bays for trucks, machinery, and equipment

• Chemical and fuel transfer zones

• Workshops, service yards, and depots

• Industrial or agricultural processing sites

Features of Our Bunded Wash Bays:

• Impervious bund walls or kerbing to fully contain the wash area

• Sealed, reinforced concrete floors for durability and leak prevention

• Waterproof joints between the floor and walls for total containment

• Integrated trade waste and treatment systems to remove and manage wastewater safely

• Designed to meet EPA and environmental compliance standards across Australia

Why It Matters

Bunding isn’t just about compliance — it protects your business, the environment, and your reputation. A well-designed bunded wash bay helps:

• Prevent contamination of soil and waterways

• Support EPA licensing and regulatory approvals

• Simplify clean-up after spills or overflows

• Enable fire safety, chemical isolation, or product recovery systems

Whether you're in agriculture, mining, transport, or local government, Washbay Specialists delivers fully compliant wash bay solutions — designed, constructed, and maintained for long-term performance.
