Using our beam and block installation service can often be the best way of guaranteeing that this important stage of your build achieves maximum value and efficiency. We have installed countless prestressed concrete floors and have the process down to a fine art, so you can rely on the quality of our work.
For ground floors onto masonry, beams should be laid on a d.p.c with a minimum bearing of 90mm. Care should be taken to ensure that the beams do not protrude into the cavity.
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.
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 wetting the floor and then brushing the grout in to form a firm cohesive bond. The importance of proper grouting cannot be overstated. Where 2 or 3 beams are placed together they should be infilled with a mix.
Domestic garage floors must have a minimum 50mm thick concrete screed reinforced with A98 steel mesh, applied directly.
As part of the installation process, we can provide ‘Fall Arrest’ where necessary in the form of low pressure air bags or safety netting.
