Floor Screeding for Data Centres
Strong level bases for technical flooring systems
HD Construction provides specialist floor screeding services for new-build, expansion and refurbishment projects within the data centre sector.
We install screed systems that create level, stable and durable bases for raised access floors, equipment areas and other specified floor finishes. Our work is carefully planned around floor tolerances, load requirements, curing periods and the wider construction programme.
Precision screeding for data centre environments
Data centres require accurately formed floors to support equipment layouts, raised access flooring and associated technical installations.
An unsuitable or uneven base can create difficulties during the installation of raised floor pedestals, equipment supports and finished flooring. It may also lead to programme delays, additional preparation and avoidable remedial work.
HD Construction works closely with main contractors, structural teams, raised-flooring specialists and other trades to deliver screeded surfaces that meet the approved project requirements.
Our screeding services
Our data centre screeding services can include:
- Traditional sand and cement screeds
- Proprietary screed systems
- Bonded screeds
- Unbonded screeds
- Floating screeds
- Levelling screeds
- Wearing screeds where specified
- Screeds over insulation
- Screeds incorporating reinforcement
- Localised floor repairs
- Remedial screeding
- Formation of falls
- Threshold and transition preparation
- Bases for raised access flooring
- Preparation for final floor finishes
The appropriate screed construction must be selected according to the approved design, substrate, required thickness, loading conditions and final floor system.
Bases for raised access floors
Raised access flooring is frequently used in data centres to create a service zone beneath the finished floor.
The pedestal system requires a suitable supporting base. Variations in the screed can affect pedestal installation, finished floor levels and the stability of the completed raised-floor system.
Our screeding work helps provide:
- Consistent levels across equipment areas
- Suitable bases for pedestal positions
- Reduced requirements for excessive pedestal adjustment
- Defined transitions between adjoining floor systems
- Accurate coordination with thresholds and access points
- Reliable preparation for following trades
The required surface tolerances should be agreed with the project team and raised-flooring contractor before installation begins.
Designed around equipment and loading requirements
Data centres can contain heavy server racks, electrical equipment, cooling systems, battery installations and other substantial loads.
The complete floor construction—including the structural slab, screed, raised-floor system and final finish—must be designed for the anticipated loads by the appropriate project designers.
HD Construction installs the specified screed system in accordance with the approved construction details. We coordinate screed thicknesses, reinforcement, movement joints and interface requirements with the relevant design information.
Substrate preparation
Successful screeding begins with a suitable substrate.
Before installation, the work area should be assessed for:
- Surface condition
- Cleanliness and contamination
- Cracks, movement and visible defects
- Moisture conditions
- Required levels and datums
- Bonding requirements
- Insulation or membrane installation
- Service penetrations and openings
- Movement-joint positions
- Perimeter details
Any condition that could affect the screed installation should be reported and resolved before work continues.
Level control and setting out
Accurate setting out is essential in areas containing raised floors, equipment bases, door thresholds and connections to adjoining spaces.
Our team establishes the working levels from the agreed project datums. Screed depths and transitions are then checked against the relevant drawings before installation.
Level-control measures can include:
- Datum verification
- Depth checks
- Finished-level markers
- Falls and drainage checks
- Threshold coordination
- Local tolerance checks
- Final floor-level surveys where required
The inspection method and acceptable tolerances should be agreed before work begins.
Curing drying and protection
New screed requires suitable curing and drying conditions before it can receive traffic, raised flooring or other finishes.
The required period will depend on the screed type, thickness, environmental conditions and manufacturer requirements.
During this stage, completed areas may need protection from:
- Premature foot traffic
- Heavy loads
- Impact damage
- Excessive draughts
- Rapid moisture loss
- Water ingress
- Contamination
- Work by following trades
Moisture testing may be required before moisture-sensitive flooring or coatings are installed.
Our delivery process
- Review the floor requirements
We review the drawings, specification, floor build-up, loading information, required levels and construction programme.
- Inspect and prepare the substrate
The base is checked for suitability and prepared for the specified bonded, unbonded or floating screed construction.
- Establish levels and interfaces
Datums, screed depths, thresholds, movement joints and adjoining floor finishes are confirmed.
- Install the screed
The specified screed system is mixed, placed, compacted and finished using methods appropriate to the product and required result.
- Cure inspect and hand over
The screed is protected during curing. Agreed level, condition and moisture checks are completed before the area is released for following trades.
Quality-control considerations
Our approach focuses on controlling the details that can affect screed performance:
- Correct substrate preparation
- Suitable bonding arrangements
- Consistent material mixing
- Specified screed thickness
- Accurate level control
- Correct reinforcement placement
- Appropriate movement joints
- Controlled curing conditions
- Protection of completed areas
- Inspection before final flooring begins
The screed system must be compatible with the substrate, intended loading and final flooring construction.
