Flooring, Tiling & Stone
Flooring performance is governed by the substrate, movement, moisture, adhesive/bedding system, layout, joint design and protection. The decorative material is only the visible top layer of a multi-layer assembly.

View details →01 · OVERVIEW
Understand the system before the detail
Like a manufacturer technical handbook, the guide starts with performance intent and then moves through components, execution, verification and maintenance.
What to expect on a project
Expect floor quality to depend on what is underneath. Levels, flatness, moisture, waterproofing, movement joints and falls must be accepted before expensive finishes are laid. Layout should be agreed from key sightlines and thresholds, not simply started from the nearest wall.
01Accept substrate flatness, strength and moisture before installation
02Coordinate levels, thresholds, drains and falls
03Dry-lay or approve layout for patterned/veined material
04Select adhesive/grout compatible with tile/stone and substrate
05Provide movement joints at the required locations
06Protect finished flooring until handover
02 · ENGINEERING FUNDAMENTALS
Why the system behaves the way it does
Engineering is easier to remember when the principle is read beside the detail. These notes connect the formula or physical behaviour to the relevant project sketch.
ENGINEERING NOTE
Material quantity = net area + pattern/cut/wastage allowance; complex stone matching may require significant selection allowance
ENGINEERING NOTE
Floor fall (%) = drop/run × 100
ENGINEERING NOTE
Adhesive coverage is an installed performance requirement, not only trowel-notch appearance; verify transfer where required
Large-format tiles amplify substrate flatness errors. Correct the substrate before installation rather than attempting to compensate with uncontrolled adhesive thickness.
Natural stone can be moisture- and stain-sensitive. Adhesive chemistry, back-coating, sealing and cleaning products should be proven with the selected stone.
Movement joints in the substrate or building cannot simply be tiled over; the finish system must accommodate the designed movement path.
