Retaining walls are the most common solution to holding back earth and soil on a sloped property and also to prevent soil erosion.  The construction of a retaining wall allows you to reclaim all of that lost land on a slope that would otherwise be unusable.  Retaining walls hold back the earth and soil and create new level areas for the construction of a parking spaces, gardens, patios, new lawns, outdoor living spaces, and more.  Retaining walls can be built using a variety of materials including boulders, blocks, bricks, natural stone or even wood such as landscape timbers.

Do Retaining Walls Require Building Permits In Kansas City MO?

Kansas City has very specific building regulations when it pertains to fences and retaining walls.  View The Kansas City Retaining Wall Regulations Here

Here are some of the specifics with regards to building a retaining wall on your Kansas City property.
  • Generally no wall over six feet high shall be erected on a residential lot.  (there are some exceptions such as with tiered walls)
  • Retaining walls in a front yard are limited to 48 inches in height (4 feet).
  • Retaining walls under 24 inches (2 feet) don’t generally require building permits.
  • Retaining walls over 48 inches (4 feet) do require a building permit.
  • Any retaining walls over 6 feet in height will require a building permit AND an engineered design.

Every property is different and these building codes only apply to Kansas City and not some of the surrounding cities and towns that we also service.  It’s best to contact us or your local municipality to determine what the requirements are for your specific property.

Proper Drainage For Your Retaining Wall

We are often contacted by potential customers who had an existing retaining wall that has failed.  The most common failure is often due to poor drainage behind and below the wall.  Retaining walls are designed to hold back earth from erosion and this also makes them excellent at holding back water as well.  The water that builds up behind a retaining wall is referred to in the landscaping 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.

Any well-built retaining wall 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, and blanket drains.  Another way to control drainage is to use very granular soil or fill behind and below the wall which can also disperse the water rather than hold it in.

What Is A Retaining Wall Surcharge?

Surcharge is the amount of weight added to the ground above or on top of a retaining wall.  This could be dirt, rock, another retaining wall in the case of a tiered wall, or even parking a vehicle such as a boat or RV on top of the earth below the wall.  Retaining walls must be designed and built to handle the surcharge that will applied or you risk having a wall failure.

Retaining Wall Materials

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.

  • Engineered block retaining walls
  • Boulder retaining walls
  • Timber retaining walls
  • Fieldstone retaining walls
  • Brick retaining walls
  • Natural stone retaining walls

The Benefits Of Using An Engineered Retaining Wall System

Retaining walls over a certain height or for specific purposes (such as tiered walls) often need to be engineered to in order to be approved for a building permit.  This can be expensive if you’re not using an engineered retaining wall system.

With an engineered retaining wall system the manufacturer has engineered the wall for specific surcharges and soil load depending on the height and material of the wall so long as very specific methods of construction are followed.  If you’re using an engineered retaining wall system it can eliminate the expense and time required to have an engineering firm sign-off on your design, saving time and saving money.

There are many different engineered retaining wall systems on the market and if this is the route you’d like to go we can help you choose the best one for your needs.

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 or we can use a pre-engineered system as we’ve described above.

  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, any surcharges the wall might have, 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.
