retaining wall

A retaining wall provides lateral support to soil, preventing downward creep on slopes. It works by resisting the earth’s hydrostatic pressure through gravity mass or mechanical reinforcement, ensuring foundations, driveways, and garden terraces remain intact. For example, a cantilevered concrete wall uses a footing and stem slab to leverage weight against soil pressure. This method of force distribution is essential for minimizing the risk of wall failure under changing environmental conditions such as heavy rain or freeze-thaw cycles. The design and engineering of retaining walls involve detailed analysis of soil characteristics and load factors, paving the way for a durable structure that not only supports the terrain but also contributes significantly to the overall landscape design.
