Supply of GRP Covered Grating and Access Hatches to the inlet works


RE-DECK504 GRP Covered Grating

RE-GRID3838 GRP Open Mesh grating

Re-STRUCT supports


The end client was NI Water. We worked in conjunction with the main contractor Ovivo, who appointed Relinea to supply and install GRP access hatches and covered grating to cover inlet works.


The inlet works is a large irregular shaped structure which required concealment for the containment of odourous gases. It further required machinery, instrument, inspection and manway access hatches.


Considering that GRP provides a non-corrosive, solid, cost effective, and anti-slip solution that can be easily installed, GRP was deemed to be the most suitable material for the application. Relinea were appointed by Ovivo to sub-contract the equipment.

The client required the inlet works to be covered using GRP covered grating. We installed GRP support beams over the trenches on the inlet works, and then after installed the RE-DECK covered grating. The inlet works had been stepped and, as a result we were able to incorporate highly visible step edging for worker safety into the installation. Finally, the access covers had to be installed with fall arrest and pneumatic rams, and lockable handles.
