Retaining Wall Installation Services In Delaware, Ohio

We specialize in the construction of new segmented retaining walls.  The benefits to segmented retaining walls are many.  Segmented retaining walls are aesthetically pleasing, they offer design flexibility, they are economical, easier to install, and durable.

They are also pre-engineered, meaning the wall can be built to your project specifications without having to have an architect or engineer design the wall itself.  We can build the wall to the engineering specifications and have a qualified engineer sign off on the project if the height or size of the wall requires it.

Do Retaining Walls Require Permits In Delaware, Ohio?

In most of Delaware County (your municipality could be different) retaining walls that are under 4 feet in height generally do not require permits or design plans.  There are some specifics that may or may not apply to your situation.  If retaining walls are 4 feet in height or over than a permit is generally required.  Any retaining walls over 6 feet in height will require a permit and additionally an engineered design to ensure the structure is sound.

When we view your property we’ll be able to let you know any specific building codes that might apply to your circumstance depending on the height/length of your wall and what it’s specifically being installed for and whatever surcharges (weight) might be applied to the soil above and behind the wall.

Proper Drainage For Retaining Walls In Delaware, Ohio

We are often contacted by potential customers who have an existing retaining wall that has failed, it’s either falling down, bulging, or collapsing.  One of the most common reasons for retaining wall failure is that the original wall was built with poor drainage in place.

Retaining walls are designed to hold back earth from erosion.  This also makes them excellent at holding back water too.  The water that builds up behind a retaining wall is referred to in the industry as “hydrostatic pressure” and the external force of the soil or fill held behind your retaining wall coupled with the weight of the water held behind it is often enough to seriously compromise the integrity of your wall which can lead to failures such as bulging and even a total collapse.

Well-built retaining walls must incorporate good drainage if it’s going to last for many years.  Depending on the type of material being used to build your retaining wall there are a variety of ways to integrate sufficient drainage such as lateral drains, french drains, weeping drains, blanket drains and also the use of very granular soil or fill behind the wall can also work to disperse rather than hold the water.

Understanding Retaining Wall Surcharges

A "surcharge" when it comes to a retaining wall is the weight on top of or behind the wall.  For example, if you're building a retaining wall to create a new parking area for a boat or an RV we need to consider the weight of the boat or RV and it's impact on the retaining wall.

If your wall is going to have a surcharge it must be built with this in mind if it's going to last.  This would also include tiered retaining walls or retaining walls with a fence on top or any other weight other than the earth it's holding back.

Geo-grid is often used to provide extra tensile strength to each course of your retaining wall so it's anchored to the ground behind it.  Proper use of geo-grid will ensure that your retaining wall will be built to last and won't collapse or buckle under the excess weight.

Failure to properly stabilize retaining walls is another very common failure.

What Materials Do We Use For Retaining Walls In Delaware Ohio?

There are many different materials to build your retaining wall out of.  Below are some of the more popular materials in our area because of their availability.

  • Block retaining walls (using high quality Unilock or Oberfields products)
  • Natural stone retaining walls
  • Large boulder retaining walls

How Our Retaining Wall Construction Process Works

When building a retaining wall on your property that is designed to hold back soil and earth from erosion there is very little margin for error so when required we work directly with engineers if your wall is over 6 feet in height.  There are many pre-engineered systems we can use as well that can eliminate the need for detailed building plans.

  1. We start with our initial consultation.
  2. We determine how many feet of retaining wall you need.
  3. We determine the height of the wall and if a building permit or engineer will be required.
  4. We take into account any surcharges (weight) the wall might be exposed to.
  5. We consult with you on the materials you’d like your retaining built with.
  6. We’ll provide you with an accurate written estimate for the work.

The amount of work required to build a retaining wall can vary widely from project to project.  The slope of your property, the amount of earth your retaining wall must hold back and the overall accessibility of your property will all contribute to the final cost.  We’ll be able to offer you an accurate estimate only after a site visit.

Retaining Wall Repair Or Replacement In Delaware, Ohio

We specialize in rebuilding wood or block retaining walls that have rotted, failed and/or collapsed.

Retaining Wall Repairs Delaware Ohio

We are often called out to repair an existing retaining wall that has collapsed or failed in some way.  This could be an old wood retaining wall that is rotting away or a block wall that is bulging or on the verge of collapse if it has not collapsed already.

Typically we don't recommend "repairing" a retaining wall.  The wall has failed for a reason and that reason is typically poor construction, a poor choice of materials, insufficient drainage, and more.  In short, a repair might not be an effective solution to your problem.  When a wall has failed we usually recommend tearing the wall out and replacing it.  This would include demolition of the old wall, re-excavating the area to allow for proper base materials, installation of proper drainage, geo-grid if required, and proper backfill.  Building your wall right is the more cost effective option in most situations.

Rebuilding Retaining Walls In Delaware, Ohio

If your existing retaining wall has failed and needs to be replaced it's usually more cost effective to demolish the old wall, remove the materials, re-excavate the site, install a proper base, geo-grid if necessary, install drainage, and build the retaining wall properly.

We specialize in rebuilding retaining walls that have failed and would be happy to provide you with a consultation if you have a wall that you believe needs to be replaced.

Questions About Retaining Walls?

Geogrid is essential in retaining wall construction as it enhances the wall’s stability and longevity. It's a geosynthetic material that reinforces the soil behind the wall, distributing pressure evenly and preventing collapse. Incorporating Geogrid is particularly important in walls over a certain height, with large surcharges such as vehicle parking, or in areas with very challenging soil conditions.

Adequate drainage is vital to the health of a retaining wall. Without proper drainage, water accumulation can exert immense pressure on the wall (hydrostatic pressure), leading to structural failure. We ensure your retaining wall includes a drainage system, like a gravel drain bed or drain pipes, to prevent water build-up and to protect the walls integrity.

Wall surcharges refer to additional loads or pressures applied to the top of a retaining wall, such as from nearby structures, vehicles, or sloped land. These surcharges must be considered in the design phase to ensure the wall can withstand these forces without compromising stability or safety.

The base of a retaining wall is the foundation upon which its strength and stability rely. A properly prepared base, typically consisting of compacted gravel, ensures even weight distribution and provides support, preventing shifting, tilting, or collapsing of the wall.

The height of a retaining wall is often regulated by local building codes and varies depending on the wall's location and purpose. Generally, walls over a certain height (usually around 4 feet) may require additional reinforcement, engineering input, or permits. We adhere to local Ohio regulations and best practices to ensure the safety and legality of your wall.

Rebuilding a failed retaining wall involves assessing the causes of failure, such as poor construction, inadequate drainage, or external pressures on a wall that wasn't built to handle them. We then come up with a plan to not only reconstruct the wall but also address these underlying issues with improved design, better materials, and proper installation techniques.

Unfortunately the wall rebuilding process often requires complete removal of the old wall so that everything can be done correctly.

The length of a retaining wall plays a big role in its design and stability. Longer walls may require additional reinforcement, such as more layers of Geogrid, or specific construction techniques to ensure the wall can effectively support the soil behind it and handle environmental stresses. We assess each project to determine the optimal design for the wall's length and intended purpose.

Yes, retaining walls can be constructed in various shapes, including curved, straight, or angular designs. The shape can influence the wall’s structural integrity and how it interacts with the landscape. We ensure that regardless of the shape, the wall is engineered for maximum stability and aesthetic appeal.

Integrating lighting into a retaining wall can enhance its aesthetic appeal and provide functional illumination. Options include embedded LED lights, or external lighting fixtures. We can help design a lighting plan that complements your wall and landscape.

Incorporating steps or stairs into a retaining wall design adds functionality and accessibility to different levels of your landscape. We ensure that these features are seamlessly integrated into the wall design, maintaining structural integrity.

Integrating planters into retaining walls is a great way to add greenery and visual interest. Planters can be built into the wall or placed on top, depending on the design. This not only enhances the wall’s appearance but also allows for easy gardening and can help with drainage and erosion control.
