Bund Lining

Bunds should be designed to contain spillages and leaks of liquids used, stored or processed above ground and to facilitate clean-up operations. As well as being used to prevent pollution of the receiving environment, bunds are also used for fire protection, product recovery and process isolation.

A bunding wall is an enclosure around oil and chemical tanks or drums that provide emergency containment in the event of failure of the tank or drum. A well designed oil and chemical bund will stop hazardous materials leaking to ground or surface water.

It is recommended that the bund wall has a minimum height of 150mm to allow for rainfall and fire-fighting foam (Reference: Guidance note for the Control of Pollution (Oil Storage) (England) Regulations 2001 para 25). Mastics/Sealants used in any joints in the bund should be compatible with the stored product(s).

Bunds are exposed to tough conditions, but continued exposure to oils, chemicals and other liquids can make them crack, corrode, leak or become contaminated.

Bunds that aren’t leak-free or safe can lead to expensive site damage, and if they breach Environment Agency pollution guidelines you could be fined.

We can solve the problem for the long term and line your bunds with an epoxy bund lining.

Epoxy resin is long lasting and copes well with normal structural movement – and because it’s impact resistant and easy to clean it’ll remain maintenance free for many years to come.

Avoid expensive bund rebuilds, an epoxy lining can mean the difference between a cost-effective bund repair and an expensive bund replacement.

• We’ll mechanically prepare your bund and make any necessary repairs, upgrades or extensions.
• Next, we’ll line your bund to create a long-lasting alternative to a complete bund rebuild.
• Best of all, we’ll normally have the job done within the week so inconvenience is kept to a minimum.

Benefits:

• Avoid expensive rebuilds
  Durable, long lasting
  Chemical, corrosion and impact resistant
  Flexible enough to deal with structural movement
  No annual up-keep costs such as painting or treating
  Long-term cost saving – 20+ years of useful life
  Minimal site disruption – normally installed in a week
  Total specialist maintenance has years of Bund Lining experience

It literally involves building a new bund within the existing structure.

Following the required preparation to remove foreign matter, our three-coat lining system is hand applied to the existing structure. The finished lining has its own structural strength with a nominal thickness of 2mm.

Our epoxy bund Linings are corrosion resistant, have excellent impact resistance and are flexible enough to deal with structural movement.

Our epoxy lining has no joints or seams and therefore creates a complete seal making your bund impermeable to both water and the storage vessels’ contents. Where movement joints and construction joints are present we will then install a chemical-resistant polyurethane sealant joint to prepare joints to provide a fully contained bund lining system

Bund wall/floor must be structurally sound, however, Total specialist maintenance is a specialist remediation contractor in concrete repair and masonry repairs.

Prior to carrying out any bund lining systems we would carry out an inspection of the bund and identify any defects that are required prior to bund lining application such as concrete repairs, host substrate checks, brickwork repairs sealant joint repairs.

Once all defects have been repaired and restored back to the original structural integrity our 3-coat system can then be applied to the entire bund to provide a fully seamless bund lining system.

No, just good housekeeping and the occasional clean to wash off dirt and any spillages.

Following the advice of our material manufacturers, the type of resins used for a bund Lining will be determined by the substance you are looking to contain and the operating environment of your bund.

Our linings can even be made suitable for some of the most aggressive chemicals and chemical mixes.

Our bund linings contain most kinds of liquids, from toxic and corrosive solutions right through to aviation fuel or dairy products. These are just some of the bunds we can line for you:
