Numerical Comparison Among Soil Capillary Breaking Layer and Common Waterproofing Techniques

Abstract Numerous damp-proof courses (DPCs) methods, including both conventional and contemporary versions, are implemented globally. This paper demonstrates the limitations of these methods. It also assesses a recently introduced waterproofing method that is based on the principles of capillary breaking layers (CBLs), which are frequently employed in earthen structures. By numerically analyzing and comparing the short- and long-term hydrothermal behavior of a few widely used DPCs with the newly proposed technique, the efficacy and affectivity of disrupting the capillary network in both short and long periods have been determined. It was difficult to distinguish the performance of concrete, bituminous, and gravel strata from the short-term studies that were conducted based on their performance. Nevertheless, the gravel layer demonstrates superior long-term performance when the proofing layer is adequately aerated.
