Steel and cementitious panels
Welded steel shells filled with a cement core for offices and technical rooms that need a quiet, solid floor under foot and good load spread between pedestals.
Raised access floors · technical flooring
A floor you can lift, wire under and close again
Pisomad USA plans, installs and maintains raised access floors: modular panels set on adjustable steel pedestals, with the space underneath kept free for power, data cabling and conditioned air.
Floor systems we work with
Every job starts from the same question: what has to run under the floor, and what load has to stand on top of it. The panel, the pedestal and the finish follow from that.
Pedestals and stringers
Adjustable heads set the finished height and take up an uneven slab. Stringers tie the grid together where the floor carries racks or heavy rolling loads.
Perforated airflow panels
Panels with an open grille or perforations placed in front of equipment, so cooled air from the underfloor plenum reaches the racks that actually need it.
Floor boxes and cut-outs
Outlet boxes and grommeted openings cut where desks and equipment will stand, so power and data come up through the floor instead of across it.
Finishes on top
High-pressure laminate, vinyl, carpet tile or static-dissipative surfaces, chosen for how the room is used and how often the panels will be lifted.
Repair and re-levelling
Rocking panels, worn edges, missing pedestal heads and floors that were opened and never closed properly are brought back to level and to a tight fit.
Where a raised floor earns its keep
A raised floor pays off wherever the layout of a room changes faster than the building does.
Server and data rooms
Cabling and cooled air share the plenum, and any panel can be lifted to reach them.
Open-plan offices
Desks move, floor boxes move with them, and nobody chases a wall or a ceiling.
Control and operations rooms
Consoles fed from below keep the working area clear and the cables protected.
Labs and training rooms
Benches and equipment can be rewired for a new layout over a weekend.
What we settle before a panel is laid
Most problems with access floors are decided at the planning stage, long before installation day.
- Finished height
- Set by what runs underneath: a shallow void for cabling alone, a deeper one when the space also carries conditioned air.
- Load rating
- Matched to the heaviest thing that will stand or roll on the floor, including the pallet jack that delivers it.
- Grid layout
- Set out from the room so that cut panels land at the edges and walls, not in the middle of the floor.
- Slab condition
- Checked and sealed first, because dust from bare concrete ends up in the equipment the floor is meant to protect.
- Edges and ramps
- Trims, steps and ramps planned where the raised floor meets doors and existing floors.
How a project runs
Small repairs and full rooms follow the same order. Only the length of each step changes.
-
Survey
We measure the room, check the slab and note everything that has to pass under the floor or stand on top of it.
-
Layout and quote
You receive a drawing of the grid, the panels and the finish, with a written quote and a schedule.
-
Installation
Pedestals are set out and levelled, the grid is built and the panels are laid and cut around the room.
-
Handover
We walk the floor with you, check for rocking panels and leave the lifter and the layout drawing behind.
Common questions
The things people ask before they commit to a raised floor.
Can a raised floor go into a room that is already in use?
Often, yes. Work can be split into zones so part of the room stays usable while the rest is built, and live equipment is planned around rather than switched off.
How high does the floor need to be?
It depends on what goes underneath. Cabling alone needs a shallow void; air distribution needs more. The survey settles the height before anything is ordered.
Can you repair a floor somebody else installed?
In most cases. We identify the panel and pedestal system first, then replace or re-level what is worn, and tell you plainly if a section is not worth saving.
Do you take payment on this website?
No. Nothing is sold or paid for here. This site has no checkout and never asks for card, bank or document numbers.
Planning a room with a raised floor?
Tell us about the space, what runs under the floor and roughly when you need it. We reply in writing with what a survey would cover.
