Portland Stone flooring can be used in a wide variety of locations from domestic houses to busy offices and public buildings. There are a number of factors that need to be considered by the designer including the paver size and thickness, but most importantly the substrate that will provide the strength.
See typical flooring substrate
Levelling screeds are normally used as an intermediate layer between the structural concrete base and the stone flooring.
There are two systems currently available; hot water pipes and electric matting.
The stone will reflect the movement in the supporting substrates.
Laying the Stone
It is strongly recommended that a Fixing Company experienced in Limestone is selected to lay the Portland Stone Flooring rather than a tiling company.
The tolerance for the standard tiles allows the designer to have 4mm joints +-1mm.
Stone Flooring on an Existing Timber Structure
Portland Stone flooring can be laid onto an existing timber structure providing a number of procedures are carefully followed.
Stone Flooring onto Pedestals
Portland Stone flooring can be laid onto a pedestal system, but it is important that the applied loadings (uniformly distributed loads and point loads) are established.
Portland Stone treads can be laid on a concrete base using a similar method to the standard flooring.
Portland Stone has been successfully used in bath and shower surrounds and steam rooms; however, we would suggest that the designer seeks specialist advice on the sealing and on-going maintenance.
Delivery and Packaging
All products leaving our works are packed in a manner to ensure safe delivery to site.
Storage and Handling
A suitable storage area will need to be set aside for the stone, which should be stored on firm, level surfaces and, to avoid contamination should be sited away from wet or muddy areas.
Over time, the action of foot traffic on a Portland Stone floor will hone the surface and form a natural patina on the surface of the tiles.
Cleaning and Stain Removal
The floor should be swept frequently with a soft brush or vacuumed to remove any dust and loose dirt.
