A retaining wall is a structure designed and constructed to restrain soil between two different elevations. It is a functional and attractive solution to unstable and sloped terrains. Retaining walls prevent soil erosion and landslide. A basement wall is a kind of retaining wall. It may also be used to enhance landscaping. We can also find retaining walls near roads or highways especially in areas where the terrain rolls. The most common types of retaining walls are timber, interlocking blocks, stacked stone, brick or block, and concrete.
Retaining walls are built to withstand pressure from soil. Water can add to this pressure and it’s very important to make sure that there is adequate drainage for water run-off. Poor drainage can result to bulged, cracked or leaning retaining walls and these won’t be able to prevent erosion and landslide.
Aside from good drainage, it would be a worthwhile idea to waterproof retaining walls as well. Concrete, natural stones, and wood are vulnerable to water penetration and water in your structure, whether it’s your home or your landscaping, is bad news. Your waterproofing barrier must be a tough and resilient obstacle to water seepage.
