Marble & Flooring Contractor in Jeddah

Choosing the flooring material for each space

The right floor is decided room by room, not once for the whole building. Three questions do most of the work: what traffic and cleaning the space will get, how much moisture and sun it sees, and how much the structure beneath it will move. The table is a starting point only; the consultant's specification and the manufacturer's data sheet have the final word.

Saudi conditions that shape the installation

• Heat and dry air shorten the working time of cement-based adhesive. If a skin forms before the tile is bedded, the tile bonds only partly and later sounds hollow. Small working areas and an occasional lift-check of a freshly laid tile keep this under control.
• Floors beside full-height glazing or at external doors swing most between hot and cool, so movement and perimeter joints matter most there. That applies to the large day-to-night swings in Riyadh as much as to summer heat in Jeddah.
• In coastal areas, salts in the base or bedding materials can migrate to the surface and leave white deposits on stone and grout. Specify clean materials and let the base dry before laying.
• Dust and grit carried in by other trades scratch polished stone and can dull polished porcelain, so the finished floor needs protecting until handover.

Setting-out, and what a good floor looks like

Setting-out decides how a floor reads. It starts from the main sightline and the door lines rather than from a corner, so cuts fall at the edges where they are least visible and thin slivers against walls are avoided. Joint lines should carry through thresholds and between adjoining rooms. Pattern floors are dry-laid first because a medallion or border cannot be corrected once it is bedded; the cut-porcelain medallion at Marina Mall in Riyadh and the decorative marble patterns at Prince Sultan University of Engineering are work with no margin for setting-out error. A good floor is flat under a straightedge, has even joints, does not rock or sound hollow underfoot, and meets doors and skirting cleanly.

Common defects and what usually causes them

• Lippage between tiles: an uneven base, no levelling system, or warped tiles laid without checking.
• Hollow-sounding tiles: partial adhesive contact, adhesive that skinned over, or large formats not fully backed with adhesive.
• Cracking: missing movement joints, structural cracks reflecting through, or a heavy point load on an unsupported tile.
• Stained or dull stone: moisture or salts rising from below, an unsealed surface, or the wrong cleaning chemical.
• Grout that dusts or discolours: the wrong grout for the joint width, washing off too early, or harsh cleaners.

Handover checks and what to put in the BOQ

• Straightedge across the floor and across joints, with lippage inside the tolerance the specification sets.
• A tap test in each area for hollow tiles.
• Joints even and aligned, grout full and clean, movement joints free of grout and sealed with flexible sealant.
• Thresholds, skirting and door clearances checked against the finished floor level.
• Slip resistance of the chosen finish confirmed for how the space is used.
• Spare tiles from the same batch handed over for future repairs.

In the BOQ, price substrate preparation, the adhesive system, the movement-joint layout and floor protection as separate lines from the material itself, so quotes can be compared like for like.
