Retaining Wall Materials - Which Option is Best?

When it comes to residential retaining walls, there are a variety of materials to choose from. You'll need to consider the purpose of the wall, the look your desire and your budget when deciding what retaining wall material is best for you. Whether you choose concrete block, stone, or another material, you'll want to understand the basics of retaining wall construction so that you can make sure your wall is designed and built correctly.

TYPE OF MATERIAL	PROS	CONS	STYLE	DURABILITY
Concrete Block	Can be used to create curves	Can only be used for walls under 4-foot tall	Slump block resembles Spanish style architecture Ground faced block is popular with midcentury architecture	Lack of footings may affect strength
Stone Veneer	Any look can be created using this type of construction Natural, custom appearance	Must be well designed, usually requiring a landscape architect or capable contractor	Natural stone varies by color and style but it's important to match the stone on existing architecture	Solid core can be designed in almost any thickness and height
Poured Concrete	Stronger than a block wall Variety of design options	Skill required for form makes for a difficult solution for residential projects May crack	The smooth, sleek form is often used in modern landscapes	Forms have to be immaculate to reduce chances of a wave or a bulge
Brick	Strong and durable	Labor intensive Requires special accommodations for drainage	Complements traditional homes and landscapes	Installation methods result in a solid structure which is extremely durable
Wood	Accessible materials Fairly simple installation	May rot Doesn't last as long as other wall materials Recommended for walls under 4-foot	Can relate to almost any style Blends into the landscape more naturally than any other material	If installed with proper materials, waterproofing and preservatives, it can last for 20 years or more
Dry Stone/Boulder	The most natural solution to grade change	Difficult to control water flow	Dry boulder and stone walls are ideal for colonial, country, and English-style gardens	Water accumulating in the interior of the wall will destroy its integrity
Gabion	Requires no special masonry or skilled labor Green alternative by using recycled materials	Wire basket may rust away in certain conditions	Complements coastal and riverside homes	Unlike most building materials, a gabion wall can move with the earth and be placed along waterfront areas

Tips for picking the best retaining wall material:

Coordinate with the materials already used on the outside of your home
Pick an option that will hold up well in your climate
Compare the cost per square foot and make sure your choice fits within your budget
Pick an easy to install material if you plan to build the wall yourself
