Application of tyre bales to slope failure repair

Landslides take a variety of forms including slides, flows, falls, topples and spreads. Many landslides require a degree of remediation to ensure that infrastructure and property are left in an acceptably safe condition. The many forms of remediation available include the removal of loose material (often also involving its replacement with more competent material), stabilisation of the remaining material and the complete engineering reconstruction of an area of the slope. In some cases quite large volumes of failed material may be removed and replaced with competent material. In general, failures that produce large holes will tend to fall into the category of slides be they circular, translational or wedge failures. However, flows can also excavate quite large gully-shaped volumes during their erosional phases. The main requirements of the fill material are usually that it should be free-draining and high friction, and should prevent internal and external migration of material in order to avoid further bu...
