When building in natural stone, there are two popular methods of construction. The traditional method is to build against a backing skin of blockwork, behind which is the cavity and inner leaf. The result is …
When an existing house is constructed with cavity walls, extending the building should always follow the ‘parallel rule’ – the term applied to both skins maintaining an equal distance apart. It is also important to …
Rain blown against a cavity wall will gradually permeate the exterior masonry skin and gravitate downwardly. Where the cavity wall incorporates an arched opening, the downward flow is interrupted and water is prevented from permeating …
Yeovil-based Cavity Trays Ltd has developed a ready-to-use solution to eliminate a reoccurring construction problem when building on contaminated land. Originally conceived for Radon gas situations, it is called the Type PAT – Protective Adjustable …
Parapet cavity walls behave differently because both faces are exposed. The prevailing document dealing with the design of masonry structures and sections is PD6697 and it states the protective DPC tray within a cavity parapet …
The provision of insulating mediums under or on top of floor slabs and to all slab edges reduces heat loss and improves the acoustic behaviour of the structure. But the question arises of whether edge …
The practice of providing support to cavity-spanning DPC’s by building into both masonry skins came about because there were few alternative options to hold a soft or pliable DPC in position. Unfortunately, the practice can …
The Type LTT is a Level Threshold Tray manufactured by Cavity Trays of Yeovil. It provides a uniform standardised construction arrangement that removes risk. By isolating one of the area’s most susceptible to damp transference, …
When site conditions dictate the use of raft construction, the builder faces a dilemma of how to bring together conflicting design aspects. In instances where there is a timber separating wall, (as depicted within the …
