Large-format tiles amplify substrate flatness errors. Correct the substrate before installation rather than attempting to compensate with uncontrolled adhesive thickness.

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.

What this activity is
What this activity is
Floor finishing includes porcelain / ceramic tile, natural stone, terrazzo, timber, vinyl and other systems. Each responds differently to substrate moisture, movement, adhesive, joint width and maintenance.
What to expect
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
Understand why the system behaves the way it does.
01
Material quantity = net area + pattern/cut/wastage allowance; complex stone matching may require significant selection allowance
02
Floor fall (%) = drop/run × 100
03
Adhesive coverage is an installed performance requirement, not only trowel-notch appearance; verify transfer where required
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.
