- How high can I build my retaining wall?
- Unreinforced retaining walls or gravity walls, can be built up to 5 ft high (1.5 m) in sandy soils and up to 3.5 (1.0 m) ft in clay soils. Masonry reinforcement works well for walls up to 15 feet high and geogrid reinforcement can handle walls in excess of 40 feet high.
- Do I need footings for a retaining wall?
- Our retaining walls are designed to sit on a compacted granular base. This saves time and money, while providing a solid base for the blocks.
- How long will my retaining wall last?
- Standard concrete building blocks made in the 1950s are still performing in building structures around the world. With today’s technological improvements, we believe our retaining walls will last a lifetime.
- How strong is a retaining wall?
- Retaiing walls can be adapted to meet the structural requirements of any site. Walls up to 5 ft high (1.5 m) in sandy soils and up to 3.5 ft (1.0 m) in clay soils typically can be installed without any pre-engineered reinforcement. Taller walls can be strengthened using conventional masonry techniques or the AB Reinforcement Grid method. Site and soil conditions determine the maximum height on any project.
- Do I require a permit to build a retaining wall?
- Permits depend on the building code of a particular city or township. We will let you know during our site visit if a building permit for landscape retaining walls is required in your area.
- Are there different types of paving stones?
- Among the most commonly used pavers are brick, concrete, rubber, and natural stones, such as sandstone, granite, slate, limestone, and travertine
- Will my paving stones shift over time?
- One effective way of keeping your pavers firmly in place is to install a good edging material (called “edge restraint”), such as concrete or metal.
