Purpose Made Cavity Trays

Special made-to-measure damp proof course units for DPC applications.

Made to order to suit the project requirements for applications such as parapet cavity walls, thresholds, and ring beams, that can be difficult and time consuming to site fabricate.

Easy to handle, yet extremely durable; preformed cavity tray systems are an effective method of DPC and present many benefits including consistent and steadfast protection, a quicker and easier installation, reduced cold bridging opportunities and site material waste.

Uses:

  • Wherever DPC is used to form a horizontal cavity tray
  • To substitute the cutting, moulding, and sealing of a DPC when forming cavity trays, angles, stop ends and column cloaks

  • Continuation of DPC must be lapped on to the purpose made unit by a minimum of 100mm.
  • All lapped joints must be fully sealed with jointing tape (not all units are supplied with jointing tape attached). It is essential that the jointing surfaces are clean and dry or the jointing surfaces will not seal correctly.
