What Is a Retaining Wall and Why Does It Matter?

A retaining wall is a structure built to hold soil back in areas where there is a significant change in elevation. Many of us have had yards that slope and then ended up with builders grading our yard. Over time soil likes to migrate towards the lower grade area. What holds the soil back is gravity, rain, freeze and thaw. This movement can cause serious erosion which can destroy landscaping, have water running away that carries plants and soil. In extreme cases it can impact the structure of a house and hardscapes.

In Central Indiana, retaining walls are a crucial element of many landscaping projects. Our soil and weather make retaining walls a must to keep yards safe and looking their best. In Fishers and Carmel areas, clay soil is very common and clay holds water. Without proper drainage, water can quickly accumulate against the back of a wall and create pressure. This pressure is one of the main causes of a failed wall. A retaining wall is so much more than just a beautiful element of your landscaping. It’s a structural element that needs to be built from the ground up correctly in order to function properly.

Why Retaining Walls Are Common in Fishers, Carmel, Westfield, and Noblesville

More recent neighborhoods in Westfield and Noblesville have more rolling terrain to their landscape. When these neighborhoods are being built it is very common for the lots to be very quickly grade out to allow for a fast turnaround for building the new homes. This leaves a very steep slope at the back of the yard which in many people’s minds is not a problem that needs to be dealt with. However, it will often lead to issues as time goes on.

Soil erosion after heavy rains

Mulch and landscape beds washing downhill

Water pooling near foundations

Difficulty mowing steep areas

Limited usable yard space

A professionally installed retaining wall will help to secure the stability of the slope of your yard and give you back control of your land. Rather than spending months fighting erosion on your yard each spring, you can have perfectly usable and beautifully landscaped levels in your yard instead.

Managing Drainage in Central Indiana

Retaining Walls | Carmel, Fishers IN One of the main reasons that we get called to build retaining walls for homes in Carmel and Fishers is to address drainage issues caused by excess rain fall. Indiana has a tendency to get heavy storms with a large amount of rain fall in a short period of time. On a steep yard, water will run down the slope. Since a lawn is not paved, water has nowhere else to go but down the slope. Along with running down the slope, the water may carry top soil and debris with it.

A drainage component is necessary in a well-functioning retaining wall system to eliminate pressure from the soil and to direct water away from the structure. The following are considered part of the drainage component of a retaining wall system:

Compacted gravel base

Clean stone backfill

Perforated drain tile at the base of the wall

Proper grading away from structures

If any of these were missing, then the water would back up behind the wall creating high amounts of hydrostatic pressure that forces the wall outwards. A properly constructed retaining wall drains surface water more effectively. Problems can arise on structures such as lawns, garden beds, patios, and a home’s foundation over time if it is not properly drainage.

Creating Usable Outdoor Living Space

While a retaining wall solves a problem it also presents an opportunity. Many of our clients in Westfield and Noblesville come to us because they want to put in a patio, fire pit, outdoor kitchen or seating area. However, with a severely sloped yard it is nearly impossible to do so without first creating a level surface.

A retainer wall allows you to divide your yard into separate levels of flat ground, so you can enjoy a variety of outdoor spaces. Instead of having to contend with a long, steep slope, you are able to divide the yard into separate levels that each serve a different purpose. For example, one level may be a patio and seating area, while a second level can be a garden bed or children’s lawn for pets to run and play.

A terrain lift is a landscape architecture technique used to elevate a portion of a site and this transformation not only increases the amount of usable space but also adds a third dimension to a landscape design.

Types of Retaining Walls for Central Indiana Homes

When deciding on a material for your retaining wall in Fishers, Carmel, Westfield or Noblesville, it is important to consider height, budget and aesthetics.

Concrete block retaining walls are probably the most common type of retaining wall. The concrete blocks are engineered for maximum strength, come in a wide array of colors and textures, and are often recommended for tall walls that need additional support.

Natural stone retaining walls look very timeless and very high-end. They are often used with custom homes and properties where the look is very important.

Boulder retaining walls are formed from natural rock and present a very organic and natural looking profile. These types of structures are often more suitable to larger properties where aesthetics and drainage are less of a concern.

Timber retaining walls are often a less expensive option for shorter lengths. However, it is important to consider that these structures do not last as long in the high moisture conditions of Indiana.

Materials used for general repairs have different design criteria and expected life expectancies. It is wise to have a competent contractor do an evaluation of your slope and soil conditions before any permanent repairs are made.

The Importance of Proper Installation

A good foundation is essential for any structure and a retaining wall is no exception. Neglecting any of the steps in this process can lead to walls that sag, split and or collapse in a few years.

A properly installed retaining wall in Noblesville or Carmel should include:

Excavation deep enough to accommodate a stable base

Compacted aggregate base material to prevent settling

Drainage stone and perforated pipe to relieve water pressure

Reinforcement such as geogrid for taller walls

Correct grading to move water away from structures

Freeze and thaw is the other major factor that affects our great state of Indiana. Water expands when it freezes. So when walls are exposed to freezing water, this expanding water is trying to find its way out, pushing on structures and soil in the process. There are numerous examples of poorly constructed structures having to relocate because of constant expansion and contraction caused by freeze and thaw. A good foundation and proper drainage will certainly alleviate this stress.

Design Features That Enhance Value

Retaining walls can also serve a purpose in being functional and also very beautiful. Many of our homeowners in Fishers and Westfield areas are really working to incorporate very unique and beautiful design elements into their retaining walls.

Tiered walls that break a steep slope into multiple levels

Seating walls integrated into patios and fire pit areas

Landscape lighting installed under wall caps

Plantings along tiers to soften the appearance of stone or block

These features are optional and add a design element to what would otherwise be a utilitarian structure.

Property Value and Long-Term Investment

In Carmel or Noblesville investing in a retaining wall not only improves the appearance of your property for the short term, but also offers years of protection for the long term. Stabilizing the soil around your home will help to keep your foundation and other structures from shifting, increasing the livability of your yard and the value of your home, and enhancing the appeal of your home to potential buyers.

One of the key factors that affect the purchase decision of a home is its outdoor area. Having an outdoor space that is well designed and maintained is something that buyers look for in a house. That’s why having a retaining wall installed to your yard by a professional landscaping contractor is a huge advantage to home improvement. It gives buyers the impression that the property has been well maintained and improved over time.

Maintenance and Longevity

If constructed correctly, a retaining wall should require very little maintenance. It is wise to keep an eye on it to ensure everything remains OK.

Look for signs of leaning or shifting

Check that drainage outlets remain clear

Monitor soil levels around the wall

Address minor movement before it becomes major damage

Routine inspections in the spring, especially after freeze-thaw cycles, can help catch small issues early.
