The answer to 'types of retaining wall installation' is that there are several common methods for installing retaining walls, each with its own benefits and considerations. The most popular types include gravity walls, cantilever walls, and reinforced soil walls.
Gravity walls rely on the weight and interlocking design of the wall blocks or stones to hold back the soil. They are a simple and cost-effective option, but require a sturdy foundation and may have height limitations. Cantilever walls use an anchored base and reinforced concrete to create a wall that 'cantilevers' over the soil, allowing for taller installations. Reinforced soil walls use a grid of geotextile fabric or other reinforcing material to create a stable, sloped wall that can be taller than gravity walls.
