Tiling around showers, baths – sign of water leaks

Cause

Leaking in-wall plumbing fittings or pipework 

Repair

  • determine the cause of the leaking – repairing leaking fittings around pipework may involve removing of linings from adjacent space or partial demolition and rebuilding of the shower
  • disconnect fittings, remove tiles, clean off substrate, replace any water-damaged framing, flooring or substrate, then rebuild the shower with new membrane applied to the correct thickness and allowed to cure and then tile and grout
  • check in an adjacent room for water stains and/or mould 

Cause

No waterproof membrane behind the tiles 

Repair

  • disconnect fittings, remove tiles, clean off substrate, replace any water damaged framing, flooring or substrate, then rebuild the shower with new membrane applied to the correct thickness and allowed to cure and then tile and grout
  • check in an adjacent room for water stains and/or mould 

Cause

Waterproof membrane damaged during tiling or waterproof membrane poorly applied 

Repair

  • disconnect fittings, remove tiles, clean off substrate, replace any water damaged framing, flooring or substrate, then rebuild the shower with new membrane applied to the correct thickness and allowed to cure and then tile and grout
  • check in an adjacent room for water stains and/or mould 

Cause

Tiles applied before the liquid applied membrane had cured

Repair

  • disconnect fittings, remove tiles, clean off substrate, replace any water damaged framing, flooring or substrate, then rebuild the shower with new membrane applied to the correct thickness and allowed to cure and then tile and grout
  • check in an adjacent room for water stains and/or mould 

Cause

Failure of grouted or sealant filled joints

Repair

  • disconnect fittings, remove tiles, clean off substrate, replace any water damaged framing, flooring or substrate, then rebuild the shower with new membrane applied to the correct thickness and allowed to cure and then tile and grout
  • check in an adjacent room for water stains and/or mould

Cause

Damaged tiles

Repair

  • disconnect fittings, remove tiles, clean off substrate, replace any water damaged framing, flooring or substrate, then rebuild the shower with new membrane applied to the correct thickness and allowed to cure and then tile and grout
