The Task
Our customer required a solution to protect the concrete surface of a
containment bund. The bund area itself would be subjected to
aggressive chemicals at high concentrations, in addition to being
subjected to a very robust physical environment.
The Solution
F.L.I. Environmental proposed the use of 10mm thick HDPE (High Density
Polyethylene) lining that was cast into the existing concrete
structure of the bund. The material was selected to be resistant to
both the chemical environment and also because of its toughness and
durability, to the practical day-to-day operational and maintenance
requirements within the contained area.
The site works involved removal of an existing coating, scabbling the
concrete walls and floor, then casting in the new material. The liner
has integral dovetail anhor studs at 150mm centers on one side of the
10mm thick sheet. The vertical panels were cast against the existing
wall with non-shrink grout and the horizontal surface was cast onto a
100mm screed laid to a fall. Upon completion of the casting operation
all joints were welded and tested on site by F.L.I. Environmental's
technicians.
