Flooring Systems

Stressline’s extensive range of prestressed flooring products allows estimators and designers to determine the most economical solution to satisfy your loading and span requirements.

Our flooring solutions include beam and block flooring, thermal flooring and hollowcore flooring. Full technical support and advice is available from product suitability, through to detailed design calculations, all free of charge.

Beam and Block

Stressline has constantly reacted to changes in modern building practices and have developed their own range of prestressed concrete floor beams, incorporating flooring grade concrete blocks able to span up to 7.5 metres.

Available for use at both ground floor, and in certain circumstances at first floor, prestressed beam and block flooring offers a flexible and dependable method to overcome difficult site conditions.

The Stressline range of prestressed beam and block, and suspended flooring provides the ideal solution where land has been made up, is sloping, or has potential contamination concerns. With the benefits of off-site manufacturing and no on site curing of concrete, it is possible to allow following trades access as soon as the floor is installed.

Thermal Flooring

Our thermal flooring option is a lightweight, cost effective and flexible solution that reduces cold bridging in floors. Used with our concrete beams – the Stressline thermal flooring is quick and easy to install using Stylite T-beam technology.

Thermal flooring can create a huge difference in achievable U values and this method of installation exceeds the thermal requirements of Part L building requirements. For more information about specific U values contact our flooring department.

Hollowcore

To compliment the beam flooring systems Stressline offer two sections of Hollowcore flooring, with spans in excess of 9 metres, either 150mm deep or 200mm deep to resolve many specification problems. Our hollowcore floors all have a self weight of 300 kg/m2 which complies to the latest sound regulations.

For more information on the hollowcore flooring solution please contact our flooring sales team at floors@stressline.net.

Thermal Flooring Installation

Our 3D Thermal Flooring Installation video is a step-by-step guide to help you understand how our thermal flooring works, and how it should be correctly installed.

Our Thermal Flooring uses Stylite T-Beam technology to reduce the cold bridging in floors, and improve the efficiency and ecological status of the build.

As well as Beam and Block, Hollowcore and Thermal Flooring products, we also offer an installation service for all our flooring items and bespoke precast stairs that perfectly compliment our flooring solutions.

FAQs

Stressline has an on-going commitment to improving both product and management systems:
  • BSI Quality Assurance Accreditation to ISO 9001
  • BS EN ISO 9001
All of our products are delivered on flat bed articulated or rigid lorries, with the option of either self offload or crane offload.
The current lead time for flooring is 5-10 working days or 4-6 weeks for hollowcore.
A membrane is normally only required if there is a Radon or gases issue to deal with.
A void depth of 225mm is from lowest part of underside of floor. This would be underside of beam for beam and block floor or insulation panel for a thermal floor. Each is at a different level.
As part of floor components package we supply EPS strips to place around the edge of the floor. This is to create a thermal barrier with the perimeter walls.
Floor beams are manufactured in accordance with BS8110 which stipulates max camber of span divided by 300 i.e. 6.0m span divided by 300 = max camber of 20mm to be allowed for in construction
Our floors are designed to support the loads advised by the architect or structural engineer. The higher the imposed and line loads the more it effects the span the floor beams can achieve.
Yes, it is good practice to always lay a Damp Proof Course (DPC) beneath the floor beams and blocks bearing onto walls.
There are a variety of blocks available from lightweight aircrete to dense concrete. The weight of block will affect the span the floor beams can achieve. We normally design for 1350kg/m3 density. We would ask you to advise us if something different is needed.
The end panels are supported by the floor beam and pushed tight to the foundation wall. The friction between the deep panel and wall surface retains the panel whilst structural topping is applied.
Yes, it is good practice to bed the planks onto the supporting walls to seal any gaps from air, heat and sound loss into the cavities.
