.: Jointless raised floors

Jointless raised floors combine the benefits of modular raised floors and traditional floors. They are economical and durable, with excellent mechanical and usage characteristics. They can be used anywhere it is necessary to create free space to place all services and wiring under the floor.

Jointless raised floors are a flooring system which provides an optimum combination of user requirements, mechanical requirements of the construction structure and project costs.

.: System elements





35 mm-thick anhydrite screed as the load-bearing layer
Access opening cover made from a raised floor panel
Desired floor surface finish
Protective aluminium angle section at the edge where the jointless floor meets modular floor
Sectional access duct, 60 or 120 cm wide, made from modular floor panels
PE sheet as a dividing layer



18 mm-thick Rigips HBS gypsum board
Outlet box to hold power, phone and computer sockets
Concrete slab, cleaned and covered with priming paint
Adjustable-height pedestal made of galvanized steel
60 x 60 cm aluminium access frame to protect access opening

.: Benefits of jointless raised floors:

  • high resistance to both static and dynamic loads;
  • highly rigid structure, practically zero deflection (f = 0.2 mm);
  • minimum linear (0.1 mm/m) and thermal contraction, which makes it possible to cover an area up to 800 sq. m without the need for contraction joints;
  • possibility to erect and fasten any dividing wall construction directly onto the jointless floor surface;
  • excellent surface smoothness;
  • all materials are inflammable;
  • high fire resistance - REI 60;
  • smoke-tight floor;
  • free space underneath the entire floor surface to lay cables and services;
  • access to services underneath the floor through access openings and/or access ducts covered by modular raised floor panels;
  • possibility to place outlet boxes at any desired location on the floor;
  • quick installation; other construction teams can access the room after just 24h;
  • resistant to damage while construction work is in progress;
  • no regular inspections and adjustments required while the building is being used;
  • excellent acoustic properties - suppression of sound carried through air and materials by a solid, continuous load-bearing plate on a flexible sound reducing layer;
  • no echo, no 'barrack effect';
  • possibility to use any type of surface finish, including cheap carpeting from a roll;
  • possibility to use parquet or stone at no extra cost;
  • economical;
  • possibility to combine it with other floor systems

    .: Floor surface finishes:

    All generally available types of floor lining can be applied as a surface finish, for example:

  • flexible plastic floor lining: linoleum, PVC, rubber
  • carpeting
  • natural and artificial stone
  • ceramic tiles
  • wooden parquet
  • metal, glass
  • special-purpose floor lining
    Surface finish materials can be applied onto jointless raised floors in the same manner as they are laid on traditional floors.

    The load bearing layer of a raised floor, made of self-levelling anhydrite is characterized by high surface quality and minimum linear contraction, which makes contraction joints both in the screed and the finishing layer unnecessary.

    .: Jointless raised floor installation:

    Preliminary work

    Prior to installing a raised floor in a building, the following work has to be completed:

  • close the building shell, install windows complete with glazing, install ventilating shaft brick settings and casings
  • install plasterboard or brick partition walls around sanitary shafts.
  • lay service trunking cradles for main cabling, a recommended solution
  • lay heating pipes / cables with thermal insulation anywhere access ducts are not planned.

    Technical infrastructure at the installation site

    For installation work the following infrastructure elements are required at the site:

  • 32 A power outlet
  • water supply
  • location for staff trailer and warehousing trailer
  • location for material storage bins
  • approx. 15 sq. m of warehousing space on the ground
  • wolny dojazd dla dostawców materiałów

    Work organization

    While installation work is in progress, the building must be protected against rainfall. The construction of a curtain wall, windows and glazing has to be completed. The interior temperature should be at least 4 °C. Openings in reinforced concrete slabs should be covered by concrete. Floor slab surfaces should be cleared of all debris, concrete or mortar leftovers.

    Step-by-step work progress:

  • clean the reinforced concrete floor slab of dirt and dust
  • proof the floor slab with priming paint that bonds with dirt and dust
  • trace the length of access ducts and mark the location of access openings
  • install access ducts and openings
  • install the floor support structure, boarding elements and expansion/contraction joints if required
  • lay PE sheet over the structure to seal it
  • lay the anhydrite screed
  • finishing work on the anhydrite screed

    Elves can be opened for pedestrian traffic after 24 h following the laying of the anhydrite screed, partial load (50% of safe load) can be applied after only 5 days, full load - after 14 days from the laying of the anhydrite screed.

    All types of wet and dry finishing work can be applied to this type of floor, just as on traditional floors, taking into consideration the floor structure safe load. Short?term dampness on the floor has no impact on the floor structure usability value.

    .: Installation cassettes:

    Installation cassettes and power outlets are a necessary feature of a raised floor and provide a way to plug any electrical or telecommunication devices into the existing cabling without problems.

    Openings for the installation of installation cassettes can be made in floor plates. We recommend the use of floor cassettes in which one can install power, telephone and computer outlet boxes with 45 module, most often used for cabling inside buildings. Cassettes and boxes may come from various suppliers. For example we recommend well-known brands such as Legrand or ACKERMANN.

    Floor cassettes may be round or rectangular and can hold between one and eight outlet boxes. Three to four 45 module sockets can be installed in each outlet box.

    Cassettes are equipped with covers to which one can apply the same surface lining as laid over the entire raised floor surface (if carpeting, PVC or linoleum is used). The cover has one or two small openings for cables, covered with their own small covers. Therefore, even if there are cables running out of the cassette, the cassette itself remains flush with the floor surface, which will ensure appropriate functionality and appearance.
