Retaining walls add beauty and protection by controlling drainage and erosion.
Retaining walls increase the value of your home and property with greater privacy and improved curb appeal. A well-designed and constructed retaining wall not only provides safety and privacy for your family, it can also help manage drainage and soil erosion, lengthening the return on your investment.
Yards come in all shapes and sizes and often times a retaining wall is what’s needed to control the movement of soil and water flow. Different applications require different types of materials. Personal taste is another factor. We will help find what works for you and what will look the best for your property. Choose from boulder, rock and block walls.
Find the right retaining wall for your project.
There are a few different types of retaining walls. Understanding the different types of walls may help you determine the proper retaining wall for your landscaping project. So what is a retaining wall construction? Retaining walls are designed to resist lateral pressure created when the ground elevation exceeds the critical angle of repose for the soil. Retaining wall calculations and design can also help manage drainage and soil erosion providing an additional degree of protection for your home and property.
Gravity walls resist lateral pressure from behind mainly from their own mass. They’re often constructed with a ‘batter’ or setback (leaning toward the retained soil) providing greater stability. Where shorter landscaping walls are needed these are often dry-stacked and constructed from mortarless stone and masonry. In this kind of application, a rigid footing is not a requirement.
There are actually two types of piling walls. Sheet pile and Bored pile. Sheet pile retaining walls are great for use where the soil is soft or there’s less space available for its construction. In this construction, steel, vinyl or wood planks are driven into the ground. Usually, ⅔ of the planking material will be driven below ground leaving a ⅓ visible above ground. Depending upon the height of a sheet pile wall, tie-back anchors may be required.
Bored pile construction is generally an acceptable alternative to sheet pile construction when the vibrations and noise levels created by pile driving is an issue.
Cantilevered retaining walls are made from an internal stem of reinforced steel, cast-in-place concrete or mortared masonry (often in the shape of an inverted T). These walls convert horizontal pressures from behind the wall to vertical pressures on the ground by cantilever loads to a large structural footing. Cantilever walls use much less material than traditional gravity wall. Depending if the cantilever wall is buttressed on the front or include a counterfort on the backside, rigid concrete footings below the seasonal frost depth may be required.
Any of the above retaining wall construction types may also be constructed as an anchored wall. Anchored retaining walls are generally used in designs where high loads are expected or due to the desired wall design or material, the wall is actually not strong enough on its own to resist the lateral pressure it receives. Anchored retaining walls provide additional strength by using cables anchored in the soil or rock directly behind it either mechanically with a cable or through a process that injects pressurized concrete.
As you can see there are several types of retaining walls and choosing the right one can depend on many different factors. The experts at DM Hardscape are here to help answer any questions you have so you can make the right decisions when it comes to building the right retaining wall for your project.
Gabion mesh walls are often constructed where groundwater is present such as the banks of creeks and rivers. They are free-draining structures that strengthen the soil by installing wire mesh boxes that are filled with cut stone and other materials.
How much does it cost to build a retaining wall?
Retaining wall cost can vary widely depending on the overall height and length of the wall and the material you build it with. Wood and stone veneer retaining walls start around $15 per square foot, while concrete retaining walls start around $20 per square foot. While retaining wall prices may vary, you can count on their benefits to be a rock-solid investment for your families home for many years to come.
