Dura Slab Recent Projects - Trench Covers for the National Grid
Comments by Brendan Dowd:
The Dura Slab 5 ton trench cover was the only solution on the market that met all of our clients requirements. The biggest benefit of Dura Slab is that given the sensitive nature of the equipment on site and their light weight, they could be installed without the need for heavy lifting equipment. Once installed, the high load bearing capacity allows site staff to travel around the site using the trench covers without having to worry about specific crossing points."
We also specified Dura Slab with built-in lifting eyes and lifting keys. This makes it very simple to install the panels and also to remove them for maintenance and servicing using the tools supplied. The anti-slip surface has already proven to be very effective. The installation period has coincided with very wet weather and I can report that there have been no incidents of site staff slipping or falling.
