Bund Walls are built to contain the unpredicted escape of liquids from storage vessels – mostly in industrial manufacturing operations. Bund walls are built to contain excess of the largest vessels capacity. Bund walls may need council approval.
Bund wall construction types that we specialise in:
- Reinforced Concrete
- Blockwork with liner or specialist joints & water stops
The bund floor and wall must be constructed of materials impervious to the contents of any tank or container within the bund. The bunded area must be capable of preventing the migration of any spillage or leakage to the surrounding environment. The bund must be built out of materials that can resist attack by any toxic substances that might be put inside it.
Services we offer for bund walls:
- Structural Design
The bund floors and walls must be strong enough to withhold any spillage from the storage facilities. The structural design should be approved by a structural engineer
Wall-type bunds at tank storages should be from 0.5 m to 1.5 m high, depending on the required containment capacity and the distance to the tank – the closer the wall to the tank, the higher the wall has to be. The distance between the tank and bund walls must be at least 1 m
- Inspection of existing with recommendations of remedials
- Testing of existing for containment
- Remedials to existing (crack remedials, jointing, water stops etc)
- Chemical resistant linings
- Carbon Fibre / glass remedials
- Sump and pump installation
A collection sump must be provided in the bund floor to make it easy to remove liquids. The floor must be graded in such a way that liquids collect in the sump. There must be no access to the stormwater system within the bund.
