Solid floor slabs full reinforced concrete plate
A floor finished on the day it is installed
The solid floor slab is a full depth reinforced concrete plate — the entire load bearing section is cast in the plant. What arrives on site is an element that carries load immediately, so it needs no support while a topping cures.
Units are connected by profiled locks along their edges. Grouting them produces a single floor diaphragm. Three trades that consume the most time on a cast in place floor disappear: formwork, reinforcement and concreting.
The solution suits projects where pace and repeatability matter — residential buildings, agricultural buildings and industrial halls. A module up to 2.40 m wide covers a typical floor plan with few elements.
In drawings the element also appears as a full depth plate or a precast reinforced concrete floor — the same product.
Solid floor slab parameters
Slab depth, span and reinforcement follow the structural scheme of the floor. The values below are fixed for the product.
EN 13747 · R60–R240 · Rw up to 50 dB
- Element form
- Full reinforced concrete slab
- Slab width
- Up to 2.40 m
- Fire resistance
- R60–R240
- Sound insulation Rw
- Up to 50 dB
- Element connection
- Profiled locks grouted on site
- Temporary propping
- Not required
- Reference standard
- EN 13747:2005+A2:2010
- Depth, span and reinforcement follow the structural analysis of the particular floor — we fix them at shop drawing stage.
- Service openings, penetrations and recesses are cast in the mould, provided they appear in the documentation before production starts.
Filigree or solid floor slab?
The same floor in two technologies. They differ in how much concrete arrives finished and how much is cast on site.
Where the solid slab works
The solid floor is chosen where propping is awkward, or where the storey has to be usable straight after the units are laid.
Residential buildings
Repeating floor plans, where a modular slab shortens the installation cycle and cuts wet trades on site.
Agricultural buildings
Farm structures where closing the shell quickly and resisting service loads are what count.
Industrial buildings
Halls and production facilities where propping would obstruct work on the storey below.
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.
