Otter Island Mexican Beach Pebble Drainage Border in Kiawah Island, SC

A drainage solution around the Kiawah Island home foundation uses a multi-layered approach: a perforated drainage aggregate layer installed to quickly collect and convey subsurface moisture, surrounded by a protective wrap and cleanout access. This is finished with a decorative top layer of Mexican beach pebbles to provide an aesthetically pleasing, low-maintenance surface that still allows water infiltration. The system promotes drainage away from the foundation, reduces hydrostatic pressure, and integrates with the coastal landscape by maintaining a neat, natural look while resisting salt exposure and sand intrusion.
