Higher floor heights

Flexible system 2000 mm between pedestials Maximum space under the floor 2000-4500 mm

HiFlex Floor is Bergvik’s raised floor with the possibility of floor heights up to 4,5 metres.

Perfect floor for higher heights

Bergvik's HiFlex Floor is the most cost-effective solution for creating an electrical room with separate cable floor below the floor. If you want a cable cellar with plenty of space for cables and other installations, then HiFlex Floor is the perfect solution. This unique floor system replaces hollow core concrete elements that are both expensive and difficult to work with. With HiFlex Floor, cable ladders can easily be mounted directly on the pedestals, either with Bergvik’s flexible bracket or anchor rail. If necessary, changes can be made right up to the installation phase without affecting delivery time or price. With satisfied customers in the mining, electricity, IT and pulp industries, HiFlex Floor sets a new standard for raised floor systems.


  • Adapted for floor heights between 2000 – 4500 mm.
  • All heavy equipment, such as e.g. transformers, can stand directly on the stable and self-supporting substructure. No expensive reinforcements are needed.
  • The flexible system enables adaptations for future expansion and modifications.
  • With up to 2000 mm between the pedestals there is plenty of space for your installations.
  • The flexible pedestal placement means that no pedestals are in the way under cabinets and cableways.
  • All installations under the floor can be mounted directly on the substructure with Bergvik’s flexible bracket.

Complete range of accessories

We provide a wide range of accessories for our floors. One example is Bergvik’s smart holder clamp for cable ladders, which is very easy to attach and offers several different options for cabling. The range also includes ventilation grilles and panels in different materials and sizes. Contact us for more information on our range of accessories.


Fastener for cable ladder bracket

Bergvik’s holding clamp for cable ladder brackets is an accessory adapted to Iso Floor and HiFlex Floor (finished floor height minimum 400 mm). They fit most of the usual ladder brackets on the market and it is also possible to attach other equipment, such as e.g. ”Canalis rails” directly to this fastener.

The holding clamp is designed for easy mounting and has two fastening pins (M10) for attaching the ladder on two sides. If fastening pins are needed on several sides, you must connect two units. The holding clamp is easily attached to the pedestal with a mount and two M8 nuts. The holding clamp comes electro-plated and is ordered/delivered complete for the mounting of two brackets per pedestal.


Ventilation grille

Bergvik’s ventilation grille in hot galvanised finish is available in several sizes and materials - both grounded and ungrounded.
Each mesh is 33x33 mm with 2 mm support profiles, which means that as much as 77% is open surface.
Contact us for more information on our ventilation grilles.


Calcium sulphate panels

Bergvik’s floor panel of calcium sulphate is a non-combustible panel and resists moisture very well.
As standard, it is coated with 0.9 mm HPL laminate (Print 577).
It can also be supplied coated with plastic or linoleum or uncoated (tongue and groove, 32 mm).

The underside is coated with aluminium foil or alternatively, steel plate. Calcium sulphate is a fibre-reinforced plaster and is
thus non-combustible. This makes it especially suitable for environments where you want to prevent smoke build-up,
such as in mines, tunnels, underground stations.
Calcium sulphate is also suitable in environments with high humidity and major temperature changes.


Panel lifter

Practical panel lifter which makes it easy to lift and place floor
panels during maintenance, installations, repairs and such.



Custom built ramp with anti-slip protection as standard. 
Can be delivered together with the associated railing.


Stairs, Railings, Ramps, Border Fascia Panels

This ensures proper, neat and safe access onto your Bergvik raised access floor.
We offer custom designed stairs, produced to match the floor finish.
We also offer aluminium railings and ramps, custom built for each project by Bergvik.
