Beam and Block
Installation is an important part of our business. In many cases beams can be installed directly from our delivery vehicle, saving time and money for the customer.
Prior to the installation our dedicated site surveyor will visit the site to check as built dimensions and to become familiar with any potential obstacles on site. In conjunction with the builder we will then formulate a plan for the installation. Most issues can be overcome.
This is particularly beneficial on small sites where storage space for materials delivered in advance is limited and room or access for cranes is not available.
Floorspan Contracts will place the beams onto a damp proof course, lay the infill blocks, bed the coursing slips and cut any necessary blocks. We will also grout the floor on completion to ensure a fully finished article.
For larger areas and upper floors it will be necessary to use a crane. If this is the case a representative will visit your site and plan the lift in conjunction with the customer.
A lift plan will be provided by a qualified Appointed Person, and a Method Statement and Risk Assessment will be issued. We are also able to offer advice on issues such as working near electricity cables and near occupied buildings.
Solid and Hollowcore Planks
Our precast Wideslab planks can be daunting to even the most experienced of builders, and it is for the reason the Floorspan Contracts offer a complete installation package. Offering advice and assistance throughout the entire process.
A qualified ‘appointed person for lifting operations’ will visit the site in advance to recommend the necessary crane size and type for the job, we will then liaise with the contractor with regard to access and rigging area. A full risk assessment and method statement will be provided.
As built dimensions will also be checked to ensure that the planks are made to the length required, which removes a significant portion of the risk from the contractor.
Floorspan contracts can also recommend and provide all forms of ‘fall arrest’ which is a legal requirement on site. This can include air bags or safety netting.
On the day of the installation Floorspan Contracts will lift all components in to place and concrete the joints on completion. Materials for concreting will be provided by Floorspan.
You can of course choose to install your floor yourself. If you choose to go down this route then there are a number of considerations to bear in mind.
Placing The Beams
Infill blocks of the specified density should be placed between beam ends to ensure the spacing of the beams is accurate. In all cases, our layout drawing will recommend a starting point for each bay. Once all beams are in position the remaining infill blocks can be placed.
Infill Blocks & Grouting
The whole floor should be grouted with a 1:6 cement / sharp sand or 1:4 soft sand mix as soon after laying as possible. This is best achieved by thoroughly wetting the floor and then brushing the grout in to form a firm cohesive floor. The importance of proper grouting cannot be overstated. Where 2 or 3 beams are placed together they should be infilled with concrete.
Domestic garage floors must have a minimum 50mm thick 20N/mm2 concrete screed reinforced with A98 steel mesh, applied direct.
