Fibrelite designed and engineered bespoke trench access covers to fit directly into the existing trenches. Covers were supplied in load ratings of D400 and A15, as appropriate to their location. The D400 load rated covers were stepped from 101.6mm deep to 50mm deep in order to accommodate both the existing rebate and required D400 load rating.

Key features of Fibrelite covers for this project:

• Strength-to-weight ratio. All trench covers can be safely removed manually while strong enough to withstand sustained loading
• Load rating tested; BSI approved
• 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
• Corrosion-resistant: unaffected by water, underground gasses and most chemicals
