Deep Bore Soakaways
Deep bore soakaways can sometimes be a suitable method of surface drainage, where ground conditions are unsuitable for conventional, near surface soakaways.
Deep bore soakaways are particularly suitable where low permeability soils overlie higher permeability rocks (e.g. chalk and limestone) and in areas of solution weathering, where near surface soakaways might cause wash-out of infilled solution features (or the creation of new ones), possibly resulting in collapse/ settlement of the ground surface.
In addition to providing recommendations, including design parameters and depths, for deep bore soakaway design, Ruddlesden geotechnical also carries out in-situ testing to verify their installation.
