Who checks tile movement joints on a Garowe floor?

Tile movement joints in Garowe go unchecked because the check happens at the wrong moment: after grouting, when a missing or grout-filled joint is hidden. A tiled floor moves with temperature and with the slab under it, and joints let that movement happen in a straight line instead of a crack. Supervision gaps in Garowe work are rarely about skill on the trowel. They are about who signs off the joint layout and who looks at the joints before the grout goes in.

What does a movement joint actually do in a tiled floor?

A movement joint gives the tile field a planned break line, so thermal and moisture movement in the screed and tiles closes and opens at that line instead of cracking a tile. Tiles, adhesive and grout each move at different rates. In hot inland conditions the tile surface can heat and cool through a wide range each day, and a floor fixed tight to a wall or poured as one unbroken field has nowhere to relieve that strain. General practice places movement joints at perimeter edges, at changes of substrate, at column and wall lines, and at regular intervals across large fields. Treat those positions and spacings as general practice, not as a Garowe rule, and confirm the joint layout against the project specification or the engineer's drawing before tiling starts.

Where does supervision break down on a Garowe tiling job?

Supervision breaks down when tiling starts before anyone has marked the joint lines on the floor. Tiling crews are paid for area laid, so a joint is one more interruption. The failure has a few repeat shapes. The joint line is never set out, so tiles run straight through where a break should be. The joint is left in the setting bed but grouted over at the finish. Adhesive bridges the joint because the tile was pressed across it. The wrong sealant, or cement grout, fills a joint that needs a flexible sealant. In each case the tile looks complete and level, and the next trade covers the area. A supervisor who arrives after grouting cannot tell a working joint from a filled one without opening it, and no client wants tiles lifted on a finished floor. Ask the municipal engineer's office whether it holds any inspection records or standard details for finishes on comparable buildings, and walk a recently completed floor in town to see how joints were handled at door thresholds and edges.

How do you inspect joints before the grout goes in?

Inspect joints in the window between laying and grouting, with the joint layout drawing in hand and a photograph taken at each line. Set the rule on site: no grouting in an area until the supervisor or project manager has signed the joint check for that area. Walk the set-out lines first and confirm they match the approved layout. Check that the joint runs full depth through the tile and the setting bed, with no adhesive or mortar bridging it. Check the width is even and the edges are clean. Check the sealant specified for the joint, and that perimeter joints are not packed tight against the wall. Record each check with a date, area and photograph, and keep the sheets with the tiling records. General practice is to confirm joint positions and sealant type against the project specification and the tile manufacturer's fixing instructions, so keep those documents on site and open at the relevant page.

What to do next

Before the next tiling area starts in Garowe, ask the engineer to mark the movement joint layout on the floor plan, then hold a short pre-grout inspection at each joint line and photograph it. Put the inspection on the programme so the tiling crew and the grouting crew both know the sequence. If a joint has already been covered, raise it with the project manager and the engineer in writing before final acceptance.
