Client Requirements

The bridge structure needed to be built at a nearby site and then slotted into its final position once constructed, to minimise disruption and ensure a faster replacement process. A hydrocarbon resistant membrane was required for the block wrapping.

Our Solution

We suggested our Landflex Elvaloy 90 hydrocarbon membrane for a number of reasons:

  • It’s extremely flexible and can provide a tight, hard wearing and long lasting cover for each polystyrene block.
  • It’s tear resistant and does not puncture or rip when in transit or during installation.
  • Its textured, non-slip surface provides an excellent key for mortar and other bonding materials.

All of the blocks were covered individually at our premises in Billericay, Essex and then transported direct to site in stages to allow continuous construction.

This enabled completion of the project within the required timeframe with a minimum of disruption to ongoing works.
