Construction sites in the UK face a constant battle against wet weather, corrosion, and heavy loads, especially when it comes to trench safety.
Traditional wooden or metal trench covers have long been the go-to option, but they come with significant drawbacks.
Enter GRP (Glass Reinforced Plastic) bridging ladders—a lighter, stronger, and safer alternative transforming trench safety across UK construction sites.
In this blog, we’ll explore:
✔ Why traditional trench covers fail
✔ The key benefits of GRP bridging ladders
✔ When and where to use them
✔ How they’re making UK sites safer
Let’s dive in!
The Problem with Traditional Wood or Metal Trench Covers
For years, construction sites relied on timber or steel trench covers, but they come with major issues:
1. Wooden Planks – A Short-Term Fix
✔ Cheap & readily available
✖ Rot quickly in UK rain, becoming weak and unsafe
✖ Slippery when wet, increasing fall risks
✖ Splinter & crack under heavy loads
Case Study: A Manchester housing project reported three near-miss incidents due to rotten wooden trench covers before switching to GRP.
2. Steel Covers – Heavy & High-Maintenance
✔ Strong & durable
✖ Extremely heavy, requiring machinery to move
✖ Prone to rust in damp UK conditions
✖ Conductive, posing electrical hazards
Real-World Example: A London infrastructure project faced delays due to corroded steel covers needing constant replacement.
Why GRP Bridging Ladders Are the Smart Choice
GRP (Glass Reinforced Plastic) is revolutionising trench safety with:
✅ Lightweight Yet Strong
-
Up to 75% lighter than steel – Easy for workers to move by hand
-
High load-bearing capacity – Supports heavy plant machinery without bending
✅ Corrosion & Weatherproof
-
No rust or rot – Perfect for UK rain, snow, and humidity
-
UV-resistant – Won’t degrade in sunlight
✅ Anti-Slip Surface
-
Grit-textured finish for secure footing, even in wet conditions
-
Reduces slips & falls compared to smooth wood/metal
✅ Non-Conductive & Safe
-
No electrical conductivity – Critical near underground cables
-
No sharp edges – Minimises injury risk
Case Study: A Highways England project saw a 40% reduction in trench-related incidents after switching to GRP bridging ladders.
When & Where Should You Use GRP Bridging Ladders?
GRP trench covers are ideal for:
✔ Roadworks & utilities – Safe pedestrian & vehicle crossing
✔ Deep excavations – Secure access for workers
✔ Temporary walkways – Quick to install & relocate
✔ Wet or corrosive environments – Docks, coastal sites, chemical plants
Pro Tip: Use GRP ladders with high-vis markings for extra safety in low-light conditions.

FAQs
Q: How much weight can GRP bridging ladders hold?
A: High-quality GRP covers typically support up to 6 tonnes, making them suitable for most construction vehicles.
Q: Are GRP ladders compliant with UK safety standards?
A: Yes, when sourced from reputable suppliers, they meet HSE and BS EN 12811-1 standards.
Q: Can GRP be used in freezing conditions?
A: Absolutely! Unlike metal, GRP won’t become brittle in cold weather.
