A tidying device for tidying between two built walls

摘要

A wall cavity cleaner tray comprises a tray 4 formed from 900mm sections of hardened plastic for collecting and removing mortar between cavity walls. The device has an open top which collects excess mortar. A disruptor device (fig 6b) may also be attached to the tray, and may include a chain (20, fig 6b). The tray may have internal fins 5, and one section may include a scoop 9. The device reduces the risk of mortar bridging the cavity gap and covering the weep holes. The device is extracted each day, cleaned and ready for use the following day
