Concrete road plates a surface made of precast
A road surface you can move
A precast road plate replaces a surface cast in place. Laid on a prepared subbase it takes traffic straight away — there is no curing period during which the area stays closed.
We produce the plates in C25/30 concrete with double ⌀6 reinforcement. The declared load class is 120 kN and water absorption does not exceed 5%, which matters through freeze–thaw cycles.
The solution proves itself on temporary surfaces — haul roads, site compounds, diversions — because the same plates can be lifted afterwards and reused. They serve equally well as a permanent surface for storage yards and parking areas.
In enquiries the product appears as a road plate, a concrete road slab or a temporary roadway plate.

- Marking
- B construction mark
- Abrasion resistance does not apply to elements intended for permanent surfaces.
- Bearing capacity also depends on the strength and evenness of the subbase — the plate alone cannot compensate for a poorly prepared foundation layer.
Where road plates are laid
The declared use covers permanent and temporary surfaces. The thickness variant follows the expected traffic.
Access and haul roads
Site access and working roads carrying heavy vehicles. Once the project ends the plates move to the next site.
Storage yards
A surface for material storage and handling equipment, resistant to point loads.
Parking areas
Parking bays and manoeuvring areas where handing the surface over quickly is what matters.
Streets and diversions
Temporary carriageways during reconstruction, laid and removed without wet trades.
What determines the price of precast elements
Precast elements are not priced from a per-metre price list — every element is designed for a specific project, and the difference between two projects of the same floor area can reach several tens of percent. So instead of a rate, we explain what actually determines the figure in your offer.
We prepare a quote within about a week of receiving complete documentation: dimensioned floor plans, sections, elevations and the site location with a postcode. The offer covers production, transport and installation — each item is priced separately, so you can see where there is room for savings.
- Element repeatability
- The single biggest variable. The same element produced in a series is markedly cheaper than a one-off, because the mould and production set-up are spread across many casts. A design based on a few repeatable types works out cheaper than one with dozens of unique elements.
- Concrete class and reinforcement
- A higher class means more cement; higher loads mean more steel. Sizing for the actual loads, rather than with excess margin, can cut the cost without compromising the structure.
- Surface finish
- A smooth, as-cast surface from the mould is standard. Form-liner textures, acid etching or architectural concrete in category BA2 or BA3 require additional formwork and tighter controls, which shows in the price.
- Factory-fitted features
- Cast-in boxes, conduits, openings and corbels increase the element price but remove the cost of chasing and fixing on site. On larger series this usually works out cheaper than doing the work on site.
- Transport and size
- The price depends on the distance and the number of loads. Elements up to 3,85 × 9,00 m travel on a standard vehicle; larger ones require abnormal-load transport with an escort vehicle and permits, which changes the calculation significantly.
- Timing and season
- Production runs in parallel with the groundworks, so ordering early gives flexibility in the programme. Forced deadlines and next-day deliveries always cost more.
