Bund Repair

Defective bunds can be more problematic than having no bunds at all, masking leaks and giving a false sense of security. Over time, unnoticed leaching of oil or chemicals can cause severe pollution incidents.

Bund Repair

Bunds originally built to meet legislation and best practice standards can become compromised over time. Accidental damage, poor maintenance, and improper design can all lead to defects such as cracks or leaks, rendering a bund ineffective. In some cases, poorly designed or constructed bunds may never have been fully liquid-tight, creating hidden risks.

A defective bund can be more dangerous than having no bund at all. It can mask leaks, giving a false sense of security while allowing chemicals or oils to leach into the ground, leading to serious soil and groundwater contamination.

We specialise in repairing and relining bunds to restore full compliance and functionality - offering a cost-effective alternative to full replacement.

Common Bund Defects We Repair

 Cracked Bund Wall Repair

Cracks can develop gradually due to weathering or appear suddenly from impact damage. Even hairline cracks can allow liquid to escape over time, compromising the containment system. When repairing a crack it is essential that the repairs do not compromise the integrity of the bund, ensuring it can handle the internal pressure of a catastrophic failure. We are experienced in repairing cracks to the requisite standard, ensuring this is done in the most cost effective manner.

 Sealing Pipe and Cable Penetrations

Unsealed or poorly sealed pipe and cable entries through bund walls are a common source of leaks. We offer expert services to properly seal these penetrations, restoring effective containment.

 Material Leaching from Bunds

Brick-built bunds are particularly prone to material leaching through mortar joints or floor-wall joints, which can cause ongoing environmental contamination. Our solution involves:

  •  Filleting floor-wall joints to prevent leaks.
  •  Applying an appropriate primer followed by a chemical or oil resistant coating to seal the structure completely.

 Bund Relining (Unlined Bunds)

Many bunds require protective linings to safeguard the substrate from the aggressive chemicals and oils they contain. Without proper lining, these materials can degrade the bund walls and floor, eventually causing failures. We conduct detailed risk assessments to determine whether lining or relining is necessary and select the most suitable materials accordingly. Relining is often a cost-effective alternative to complete bund replacement, especially for bunds built with unsuitable materials such as porous concrete blocks.

 Bund Upgrades

If your operations have changed - such as an increase in liquid storage volume or a change in the materials stored - your existing bund may no longer meet compliance requirements. Our bund upgrade services include:

  •  Increasing capacity to accommodate greater volumes
  •  Relining to protect against more aggressive or different stored materials
  •  Retrofitting sumps and automatic bund dewatering devices to enhance functionality and maintenance efficiency
