A preformed curved damp proof tray with integral stop end and water check for use with concave or convex curved cavity masonry.

Concave or convex cavitrays in four types to suit generic applications:

  • Curved common openings – window and door openings, usually with a curved lintel. This type is accommodated by a curved version of the Type C cavitray.
  • Curved arresting barriers – similar to common openings but the base leg of the cavity tray does not project through to the outside of the masonry leaf. The function of the arresting barrier is to arrest and minimize any water wash above features intruding wholly or partly into the cavity, e.g. over the top of a horizontal cavity fire barrier or full fill cavity insulation. This type is accommodated by a curved version of the Type Q arresting barrier.
  • Curved horizontal intersections – Modified versions of the Type G general purpose cavitray are available for use at horizontal intersections with a curved wall. A typical application is the abutment of a bay window.
  • Curved sloping abutments – The intersection of a pitched roof against curved masonry is complex necessitating a three dimensional approach – satisfied by individually angled versions of the Type X gable abutment cavitray.


  • Ready to use, custom made module cavitrays to suit project specific configurations.
  • Cavity width adjustment ensures compatibility.
  • Available with attached lead flashing.
