In your backyard Terraces can create several mini-gardens in your backyard. On steep slopes, terracing can make planting a garden possible. Terraces prevent erosion by shortening the long slope into a series of shorter, more level steps. This allows heavy rains to soak into the soil rather than run off and cause erosion.
Numerous materials are available for building terraces.
These materials will last for years. Other materials for terraces include bricks, rocks, concrete blocks, and similar masonry materials. Some masonry materials are made specifically for walls and terraces and can be more easily installed by a homeowner than other materials such as field stone and brick. Most stone or masonry products tend to be more expensive than wood. The steepness of the slope often dictates wall height.
