4.1.5 SelectionThe soil often varies across a site or by depth. If an
unsuitable soil is found by excavating at a specific location, a better soil may
be located either above or below it or elsewhere on the site. Soils of varying
properties can be selected in this way for blending to give the desirable
properties for a daub. If a suitable earth cannot be created from materials on
site, then appropriate materials can be bought in. Suitably graded aggregates
can be selected using an appropriate guide, such as the English Heritage
Directory of Building Sands and
Aggregates.[61]
