Ceramic Tile Delamination

Remedies for delamination if drummy sounding areas on a slab are easily detectable by hammer or chain dragging the subsurface probably contains voids.

Ceramic tile delamination.

It only takes a fraction of that movement to cause a tile floor to delaminate. A concrete slab one hundred feet across can grow and contract over half an inch. In this case spalling and delamination affected no more than 5 of the tiled surface area. It originates from the presence of trapped air during pressing and elastic recovery of the pressed material which prevents the consolidation of the pressed material.

Avoiding delamination is a solid argument for choosing both high quality clay and manufacturing credentials when selecting a clay plain tile for the roof. After all a clay plain tile roof at 60 tiles per m 2 laid at a broken bond and double lap is the one of the most expensive and complex systems a customer may choose for a roof. Answer answer whether it is stone tile or ceramic tile or porcelain tile or glass tile if the tile becomes loose or unbonded then we refer to that either as a tile that debonded or we might say the tile has delaminated from its substrate. Rather than replacing tiles we utilise the pressure injection of injectabond adhesive beneath affected floor wall internal and external tiles.

The ceramic tile is delaminating due to water exposure in the shower. The difference between concrete s rate of expansion and contraction and that of ceramic tile is about 10 to 1. Delamination is a typical defect of ceramic tiles. As a general principle if spalling had occurred to tiles over 15 of the roof surface area then there has to be strong justification for complete renewal of the roof tiles.

The injectabond then reglues tiles at the point of delamination and provides a positive bond from substrate to tile.
