What is a raised access flooring system?

A raised access floor is a platform built several inches above the structural floor, creating a cavity/void between the existing floor/slab and the top surface of a raised access floor system.

Why consider a Raised access floor system (RAF)?

The cavity created by the raised access floor system can be utilized for passing mechanical, electrical, and plumbing-related services.


Where can these be used?

Offices, Data Centers, Critical rooms Casinos, Control Rooms, Co-working Spaces, Educational Institutes, External Spaces and more


The rates of screed / traditional IPS are comparatively lower?

Screed / Traditional IPS costs are lower; however, screed offers no value addition to the client. 

The added value of raised access flooring systems is that the screed cost (during installation) and the recurring relocation costs are nullified in the future.


With an approximate 30,000 sq. ft. floor plate area, the curing time is roughly 20 days, wherein no other agencies can work parallelly. Additionally, if the facility is in a pre-occupied tenant building, screed (wet works) can tend to seep through the floor, causing damage to the facility below.


How can we save on partition costs with raised access flooring system?

Raised Flooring is a water levelled floor. Therefore, the partitions can be pre-planned, saving the partition cost as the partition length has decreased significantly.


Technical queries

Why are loading parameters essential to determine the grade per the Flooring application?

The loading parameters for the Open Office application are determined based on the required uniformly distributed Load (UDL). In contrast, the Critical Rooms / Data Centres / Control Rooms etc., are determined based on the required Load. Therefore, if there is a mismatch in specifications, you can suggest an equivalent product based on the above parameters.

Do we need more floor-to-ceiling height to use a raised access flooring system? What will be the clear cavity we get?

The minimum finish floor height (FFH) that we can achieve with raised access flooring systems is 65mm; with this, you get a clear cavity of roughly 30 to 35mm, varying on the undulations of the subfloor. In addition, we can install the flooring directly on the mother slab without needing any IPS / Screed; hence, there will be further height savings. 

A detailed site survey report with a laser levelling technique is conducted to determine the lowest FFH we can achieve based on site conditions and undulations.

Can Partitions be installed on top of a Raised Access Flooring System?

Yes, the office partitions usually increase the loads on the raised floor by 1,000 kgs per sq. mt. which can easily be carried by any of our raised access floor systems. 

This, in turn, will make routing the services in the underfloor void much simpler and means that the office re-configuration will not leave holes on the raised floor at a later stage.


What about the acoustics issue that may occur by installing a partition on the raised floor system?

We have not received any complaint concerning the transmission of noise/sound from one area to another. Also, the carpet (top finish), installed on top of the raised access flooring systems, acts like an acoustic barrier. However, you can use acoustic obstacles if a specific need exists in a few areas.

What about the undulations in the subfloor?

At the initial stage, our project management team visits the site, undertakes a laser levelled survey of the entire floor plate, and demarcates the points at different locations on the shop drawings. Based on that data, we pre-plan our pedestals to ensure any undulation on the subfloor.

How do you fix the pedestals on the mother slab?

In the case of Office areas, we use glue for bare raised access flooring systems to ensure that the bonding between the pedestal base plate and mother slab is rock solid. For Critical Room applications, we use glue till 450mm FFH; above that, we anchor the pedestals to the mother slab with fasteners.

Can one make ramps with raised access flooring systems?

Unitile offers a value-add Ramp Shoe solution composed of heavy-duty anodized aluminium compatible with the raised access flooring systems ensuring that your entire office space is modular and flexible. The dimensions of the Ramp Shoe are 2000mm (L) x 395mm (W) x 50mm (H), along with the dust matting strip integration, ensuring that the dust and debris are restricted at the entrance. A specially designed swivel head is used, which rotates 180 degrees to provide an accurate ramp slope.

Can one make steps with raised access flooring systems?

Yes, steps that are widely applied in auditoriums and classrooms can be easily achieved with the step-up application. This system is a technologically advanced superior step pedestal on which we can achieve two different finish floor heights on the same pedestal.

How do you cover the front facia after installing the step-up raised access flooring?

The front facia can be covered with the help of carpentry work having any desired finish on top or Axiom (Extrude Aluminium section) profile which will be in the scope of the General Contractor.

How do you protect the perimeter panels and the cut-outs made in the Panel from moisture and dust?

The general practice is to use aluminium foil tape to seal the cut-outs to ensure there is no ingress of moisture and dust.

Common challenges

How do you guarantee a squeak-free / noise-neutral floor?

The technologically advanced Unifold panels come with 3.25 double fold wrapped technology around the perimeter, leaving no play for the panels to overlap on top of each other and sit perfectly aligned. Due to these parameters and other design enhancements like increased footprint area, corner radius and beam width, we guarantee a noise-neutral floor for the facility's lifecycle.

Is there any solution to the poor edge beeding that chips off?

Yes, many times, due to non-adherence to good installation practices at the site, workmen tend to lift the laminate panels with screwdrivers and other such methods while accessing the underfloor services. 


Unitile offers a calcium sulphate panel with an aluminium edge profile that creates a perfect bond that further protects the edges from getting damaged.


Certifications & Warranty

What is the warranty on Raised Access Flooring Systems?

Unitile offers a 1-year warranty for raised access flooring systems on all technical loading parameters, and the system last the facility's lifetime, which is 25 years.
