CACTUS (Climate Adaptation Control Technologies for Urban Spaces) is an ongoing research project that is investigating the development of “climate adaptation composite barrier systems” capable of limiting the impact of a changing environment on buried geo-infrastructure, such as retaining walls and foundations. The project partners are investigating: (i) a range of potential soil types (with amendments) that will meet the desired requirements of climate adaptation engineered barriers (permeability and water holding capacity); (ii) the independent and combined impacts of wet-dry and freeze-thaw cycles on the volume change and strength characteristics of the potential barrier materials; (iii) appropriate species of vegetation that can promote removal of water from the water holding layer; (iv) experimental modelling of stress-deformation characteristics (lateral and axial) of the soil systems when subject to wetting and drying; (v) numerical modelling of the composite barrier systems to develop protocols for implementing the novel systems; (vi) trial implementation of the proposed technologies at field scale.
