There are a number of things you must consider before deciding to build a retaining wall. These include the wall’s size, purpose, location of load, and seismic design. The materials used also contribute to the longevity of the wall.

If retaining walls are more than 30 inches high, guardrails should be installed. Guardrails are recommended for walls that exceed 10 feet in height, according to some code officials.

You may also need a site development permit. This permit is required for special conditions. It may also be required in conjunction with other approvals.

In some cases, a permit for a retaining wall isn’t necessary. Some cities exempt retaining walls less than 4 feet from the building permit process. If the wall is smaller than 30 inches in height, the permit is not required.

A building permit may be required if the wall is taller than 4 feet. A permit may also be required for walls that are more than 100 feet from a water source.

Depending on where you live there might be more involved in building a retaining walls. In addition to a permit, you may need to hire a retaining wall contractor or design professional to build the wall.

Types of retaining walls

Anchored retaining wall are a great choice for walls too thin to use sheet piles. They provide additional strength. They are susceptible to sunburn.

Retaining walls are often constructed with stone blocks or concrete blocks. They can also be made from bricks or pavers. They come in many styles and colors. They can also be installed in a number of ways, including on site.

The most common type is the cantilevered wall. They consist of an internal stem and a base slab. The base slab is typically made from concrete or stone, but it can also be made of metal or stainless steel. Cantilever walls are also known by the “L” shape. These walls can be built on site or precast in a factory.

Counterfort retaining walls are similar to cantilever walls, but they provide an additional level of strength. They reduce soil’s bending moments. They can be precast or made on-site.

Gravity retaining walls are another type of retaining wall. They rely on soil weight to hold it in place. Gravity retaining walls usually have sloped faces and a setback. Gravity retaining walls can withstand higher lateral earth pressures at deeper depths. However, they can become too heavy for the ground below them.

Stone retaining walls

The dry stack method requires no mortar between stones, which allows water to naturally drain through the wall. It is also much easier to repair than wet-stone retaining walls.

Another option is to lay a geogrid. This is a net-like mesh that extends into soil behind the wall to support it. This will prevent soil from shifting around and also help support the wall’s structural integrity.

The dry stack method is not suitable for walls more than three feet high. It also lacks the durability of a poured concrete wall.

The dry stack method is also easier to install than a mortared wall. This method can be used to build retaining blocks walls, but it might not be the best for a retaining wall.

Proper drainage is essential when building a stone wall retaining wall. Proper drainage will not only prolong the wall’s life expectancy, but it will also prevent soil from pushing through cracks in the wall.

If you plan to build your retaining wall using traditional mortar, it should be mixed properly throughout the project. This will make the mortar stronger and longer lasting. You should also use a finishing tool to smooth the joints. Masonry adhesive may be required if you plan to build a tall wall. This adhesive will be a great choice for concrete-to-concrete projects.

You may also want to consider using a moisture membrane to help prevent water runoff from forming behind the concrete blocks. A rubberized brush-on waterproofing product is also available.
