Retaining walls serve the essential purpose of providing structural support and preventing soil erosion in various construction projects. These walls are designed to resist the lateral pressure exerted by soil or water, effectively retaining and stabilizing the land or slope behind them. The primary goal of retaining walls is to prevent the natural forces of gravity from causing the soil to collapse or slide, thereby maintaining the integrity and safety of the surrounding areas. Retaining walls are commonly employed in a wide range of applications, including residential and commercial developments, highway and railway infrastructure, landscaping projects, and environmental protection initiatives. By effectively holding back soil and controlling the movement of earth masses, retaining walls ensure the stability of structures and landscapes, promoting both functional and aesthetic benefits.

The primary purpose of drainage in hardscape is to redirect and control the flow of water. Without adequate drainage, water can collect and pool on the surface, leading to a range of issues. Prolonged exposure to standing water can cause damage to the hardscape materials, such as cracking, heaving, or deterioration. It can also create safety hazards by making surfaces slippery and increasing the risk of accidents.

Proper drainage helps prevent erosion and moisture-related problems. It ensures that water is efficiently channeled away from the hardscape, reducing the potential for soil erosion and the weakening of the foundation. Drainage systems also help protect adjacent structures, such as buildings or retaining walls, by diverting water away from their foundations and preventing water infiltration.
