In built-up areas, virtually every power, water, gas and communication line runs underground. Their greatest risk is an excavation opened years later along the same route.
As set out in specifications accepted worldwide, a cover plate is laid over the cable once the required bedding is in place. The bucket meets the plate before it meets the cable. The operator learns that a line runs below and continues by hand.
The plate is made from recycled plastic. Underground it does not rot, corrode or crumble; decades later it is still a legible warning for the crew digging above it. Its purpose is not to carry the line, but to stop the dig.
Five standard sizes are produced from stock. The base size is 20 × 30 cm × 5 mm; width, length and thickness can be customised on request.
For custom production the maximum dimensions are 600 mm wide and 2500 mm long.
Quantities assume the plates are laid end to end; overlapping installation increases the requirement. The strip type (150 × 1000 mm) is used on long runs to reduce the number of joints.
The plate is the single step between laying the line and closing the backfill.
The trench is dug to the depth given in the specification and a sand bed is laid at the bottom. The bedding separates the line from stones and sharp fill.
The cable or pipe is placed on the bedding and covered again with sand. The plate rests on this covering layer, not directly on the line.
Plates are laid end to end along the route, aligned to cover the line continuously. On wide routes two rows are laid side by side. No cutting, drilling or fixings are required.
The trench is filled and compacted layer by layer. The plate then waits in place until the next excavation; its work begins only on that day.
Depth, cover thickness, plate size and laying pattern follow the project specification; the steps above show the general sequence of work.
The most common application, on medium- and low-voltage lines. It is the first physical warning layer where a line cannot be located before digging.
On pressurised lines, bucket contact causes both outages and ground collapse; the plate stops the dig before contact.
The highest-risk line type. Used together with warning tape, the plate provides a two-stage warning.
The most expensive lines to repair, with the widest impact when cut. The plate marks the route years later.
Standard loading plan for the base size. Pallet and container quantities for other sizes are calculated on request.
Plates are packed in units of 50 and loaded onto 100 × 120 cm Euro pallets. Each pallet holds 80 packs, i.e. 4,000 plates. A 40' container takes 20 pallets — 80,000 plates in total.
* Figures apply to the 200 × 300 × 5 mm base size.
Packs are strapped and shrink-wrapped; pallet edges are secured with corner protectors.
Pallets ready for dispatch in the factory warehouse.
Container loading: pallets are set in rows and the gaps secured with dunnage air bags.
Next to the cost of a strike during excavation, the cost of a plate is a rounding error.TULUX · cable cover plate
A single layer added while the line is laid protects both the operator and the city years later.
