Project overview

Fibrelite provided a lightweight retrofit replacement for failing heavy concrete trench access covers over an existing oxygen pipework trench at this UK hospital.

Problem

The previously installed concrete trench access covers over an oxygen pipework trench at this hospital were causing a number of issues due to both their weight and deterioration.

Key issues:

  • The sheer weight of the previously installed concrete covers made them time-consuming and costly to remove and replace, as well as causing health and safety risks.
  • The concrete covers were located on a public walkway and were causing a trip hazard for pedestrians because they had begun to degrade and crack.
  • Potential to decelerate essential maintenance and repair works due to the time required to remove and replace the covers.

Solution

The Fibrelite technical team attended the site to conduct a full survey, following which they custom designed and manufactured a bespoke retrofit covering solution which fit directly into the existing frames.

Key benefits:

  • All Fibrelite trench access covers can be safely removed and replaced manually by two people, saving time and cost.
  • Quick and painless to install, no need for concrete break out: Fibrelite’s custom manufactured trench access covers were retrofitted directly into the existing frames.
  • Corrosion resistant: Fibrelite’s access covers are unaffected by water, underground gasses and most chemicals.
  • Independent wet and dry tests carried out by Devon CC Materials Laboratory showed that Fibrelite manhole and trench covers – even when wet – have anti-slip/skid properties far exceeding health and safety advisory limits.
