Tiling.
Most tiles that lift, crack or sound hollow were fixed with the wrong adhesive, too little of it, or no movement joint. These guides explain the adhesive classes printed on every bag, how much adhesive and grout a floor takes, which trowel suits which tile, and when an epoxy grout earns its place. The figures come from the manufacturers' technical data sheets, and every guide links to the product pages where those sheets can be downloaded and the quantities calculated.
