Belgard Retaining Wall


Retaining walls are one of the masonry structures that require more labor, care and attention to detail in order to avoid structural failure down the road.

We are going to list a few pointers, but if the wall is taller than 4', our recomendation is to look for professional help as you will start needing permits, plans and other items.

In general, retaining Walls are structures meant to hold the weight of the soil on a previously existing slope. If your property has a big slope that creates unusable space, a retaining wall might be right for you!!!

There are two main types of walls, masonry walls (created by stone, concrete or other material) and gravity walls (created by interlocking concrete blocks). Both of them have similarities and differences that might make one more favorable for your house than the other.

Retaining Wall

- Masonry Retaining Walls:

These walls consist of big reinforced footings that will hold either a stone wall, a brick wall or a concrete wall. Disregarding the chosen material, all walls need to be reinforced accordingly with their length and height. The taller the wall, the more load it will need to sustain.

These types of retaining walls are stationary. They do not allow for movement other than contraction and expansion, so a proper drainage will need to be installed at the bottom as well as a layer of gravel from top to bottom on the back of the wall. Remember, the more water you evacuate from behind the wall, the less pressure the wall will have to fight against!

Gravity Wall

- Gravity Walls:

Gravity Wall is a term that is becoming more popular these days. It is a wall created of interlocking concrete blocks. These pieces sit on top of each other without the need of any cement or mortar, and are able to hold the weight of a mountain by just their own weight, shape and a little set back.
These walls do allow for more movement than the masonry walls, but such movement (other than expansion and contraction) is still not desired! So, remember that strong footings and proper drainage is still needed!

These walls use an anchoring systems to lock the blocks in place, but since their installation is faster, the cost of these walls is reduced in many situations.

In almost every city in Maryland, all walls higher than 30" will require a permit, and all walls higher than 4' will require engineered plans and other procurements. We will help you along the way through every process. Please, retaining walls might become a hazard when built by a non licensed contractor. Do your research before hiring somebody!!!

A retaining wall installation is more complicated that what it might seem. There are many details and techniques that are not explained here. If you need a professional to install or just help you with your project, gives us a call. We offer free estimates for all Montgomery County and Maryland!
