Block & Beam Flooring Supply
Design and supply of durable precast concrete block and beam flooring systems for residential and commercial developments, including prestressed beams, infill blocks and coordinated layouts.
Precast Block and Beam Flooring Systems
Block and beam flooring is a suspended precast concrete floor system formed using prestressed concrete beams with transversely tested concrete infill blocks positioned between them. The finished system creates a robust structural floor that can be used on domestic, commercial and mixed-use projects.
One Stop Consult works with established supply-chain partners that manufacture high-quality prestressed beams in commonly used 150mm and 225mm depths. The beams are selected and arranged to suit the proposed spans, loading requirements and building layout.
The system provides a practical alternative to in-situ concrete and is widely used for suspended ground floors across the UK. It can also be used at upper-floor level where the structure and design allow.
Why Choose Block and Beam Flooring?
Precast flooring offers a strong, durable and efficient solution for a wide range of construction projects.
Fast Installation
The beams and blocks can be installed quickly once the supporting walls and bearings are ready.
Durable Construction
Precast concrete provides a robust and long-lasting floor structure with strong resistance to moisture and decay.
Long Spans
Prestressed beams can span substantial distances, helping reduce the need for excessive intermediate support.
Cost-Effective Solution
Off-site manufacture and efficient installation can provide good value compared with some traditional floor systems.
Reduced Ground Risk
A suspended floor can help manage sites where ground movement, made ground or variable conditions make ground-bearing slabs less suitable.
Flexible Applications
Systems can be used for houses, extensions, apartments, commercial buildings and selected upper-floor arrangements.
What Is Included in a Block and Beam Floor?
The exact supply package depends on the manufacturer, project layout and agreed scope, but the core system is formed from prestressed concrete beams and concrete infill blocks.
The design should be coordinated with the foundation layout, load-bearing walls, service openings, ventilation requirements and proposed floor finish.
150mm and 225mm Prestressed Concrete Beams
The original OSC service page confirms that supply partners manufacture prestressed concrete beams in 150mm and 225mm sizes.
150mm Beams
Commonly used where spans, loading and floor-depth requirements are suitable for a shallower beam section.
225mm Beams
Deeper beams may be selected where longer spans or greater structural capacity are required.
Project-Specific Selection
Beam depth and spacing are determined by the structural layout, imposed loads, span and support conditions.
Manufacturer Design
The final beam arrangement should follow the manufacturer's approved design and installation information.
Where Can Block and Beam Flooring Be Used?
The system is widely used for suspended ground floors and can also be suitable for selected upper-floor applications.
New-Build Houses
A popular solution for suspended ground floors across housing developments and individual new-build homes.
Extensions
Suitable for many domestic extensions where a suspended concrete floor is preferred over a ground-bearing slab.
Apartment Developments
Can be incorporated within low-rise residential schemes where the structural arrangement is suitable.
Commercial Buildings
The system can serve offices, retail units and other commercial buildings subject to the required loading and span.
Upper Floors
Beam and block flooring may also be used above ground level where bearing, access, loading and acoustic requirements are addressed.
Challenging Ground Conditions
Suspended floors can be beneficial on made ground, shrinkable clay or sites affected by ground movement.
Design Coordination Before Manufacture
The floor design should be coordinated before beams are manufactured. Accurate dimensions, wall positions, bearing details, openings and loading information are essential to avoid delays or changes on site.
The floor layout must also work with the structural engineer's design, foundation construction, drainage and service routes, damp-proofing, insulation strategy and final floor build-up.
How the Block and Beam Supply Process Works
Providing clear and coordinated drawings at the outset helps the manufacturer prepare an accurate design and quotation.
Project Review
Review the floor area, plans, sections and structural support arrangement.
Quotation
Coordinate a supply quotation based on the drawings, beam requirements and delivery details.
Floor Design
Prepare the beam layout, spacing, bearings and any required trimmer arrangement.
Approval
Confirm dimensions and design information before production.
Manufacture and Delivery
Manufacture the beams and arrange delivery to the project address in accordance with the agreed programme.
Preparing the Site for Installation
Supporting walls and bearings should be complete, level and built to the approved dimensions before the flooring arrives. Suitable access, unloading arrangements and lifting equipment should also be planned in advance.
The floor must be installed in accordance with the manufacturer's layout and project-specific structural information.
Insulation, Ventilation and Damp Protection
The structural beam-and-block deck forms only part of the completed floor. Thermal, moisture and ventilation details must also be coordinated.
Floor Insulation
The insulation thickness and position should follow the SAP design, U-value requirement and selected floor build-up.
Sub-Floor Ventilation
Suspended ground floors commonly require suitable ventilation to the void beneath the floor.
Damp-Proofing
Damp-proof courses and membranes should be coordinated with the supporting walls and finished floor construction.
Screed or Topping
The final floor finish may include insulation, membrane, screed or a structural topping depending on the design.
Information Required for a Quotation
Provide the full project address, latest floor plans, foundation or supporting-wall layout, sections and the approximate delivery date.
Please identify all openings, changes in level, internal load-bearing walls, stairwells, service zones and any unusual loading requirements.

Important Block and Beam Supply Information
The final floor design depends on confirmed dimensions, spans, loading, support conditions, service openings and project-specific structural information. Drawings should be checked and approved before manufacture. Supporting construction, lifting arrangements, safe unloading and installation remain subject to the agreed supply scope and contractor responsibilities. Changes made after approval may affect cost, programme and product suitability. One Stop Consult provides consultancy, coordination and supply-chain support through its specialist partners.
Block and Beam Flooring FAQs
What is block and beam flooring?
It is a suspended precast concrete floor formed from prestressed concrete beams with concrete infill blocks positioned between them.
What beam sizes are available?
The existing OSC service confirms that supply partners manufacture commonly used 150mm and 225mm prestressed beams.
Can block and beam be used for upper floors?
Yes, in suitable projects. The structural layout, loading, bearing, acoustic and installation requirements must all be considered.
Is block and beam suitable for extensions?
It can be an effective solution for many house extensions where a suspended concrete ground floor is required.
