Cheapest Retaining Wall – How to Make a Cost-Effective Retaining Wall with Sakrete Bags

It’s not the prettiest but this is the cheapest and easiest way to build a retaining wall!

We had a big issue with the drainage ditch next to our house. It would get close to flooding our air conditioners just about every time it rained hard.

Hubby had the idea to use Quikrete to build a wall. We started with a few bags and then added to it over time. Took a few years but it was worth it! We did have a very ugly line of bags of concrete for about 2 months u

This is why we installed the wall. As you can see we get a river in the ditch next to the wall. It was really bad.

The bags weigh 10 – 80 pounds each so doing an entire wall isn’t easy unless you get them delivered or have a big truck. That is why we bought them 10 at a time – that was the most weight I wanted in the back of my Armada. v

It worked! The water will rise to the top of the bags but doesn’t go over anymore so this $100 investment is saving us $10k in air conditioners!

We built the wall and just let it go for a few years – I think this wall is about 5 years old. I finally got around to adding a coat of spray paint and I like it much better – the bags of concrete now blend and match the house a little better!

As a homeowner, you may be looking for a durable and cost-effective solution to landscape erosion or to define areas in your garden. Building a retaining wall is a practical way to accomplish this, and using Quikrete bags can be an economical choice.

NOTE – these are ONLY for very small retaining walls – you shouldn’t do this for structural walls or any type of support. This is ONLY for keeping water or things in certain areas or for decoration.

Here’s how you can construct a retaining wall without the need for mortar, making it not only cheaper but also a feasible DIY project.

Materials Needed

  • Quickrete or any other concrete mix bags
  • Shovel (optional)
  • Level (optional)
  • Tamper (optional)
  • Gravel (optional)
  • Water

For real all you need is the bags and some water. The other items just make the wall “prettier”.

Step-by-Step Guide to Building Your Retaining Wall

Step 1: Plan Your Wall

Before you begin, plan the location and layout of your retaining wall. Consider the height and the total length, and check for any utility lines that may be in the way. You really don’t want to go over a few bags tall.

Step 2: Prepare the Foundation

Clear the area of debris and level the ground where the wall will be built. A solid foundation is crucial for the longevity of your wall. Optionally, you can add a layer of gravel for better drainage and stability.

Step 3: Lay the First Layer of Quickrete Bags

Lay the bags tightly against each other, starting from one end and working your way to the other. Use the level to ensure that the bags are even. If necessary, use the tamper to compact the bags into place.

Step 4: Wet the Bags

Once the first layer is laid out and level, thoroughly soak the bags with water. The concrete will begin to harden within the bags, creating a sturdy base for the following layers.

Step 5: Stagger the Next Layers

For additional layers, place the bags so that the seams are staggered from the layer below. This will add stability to the wall. Continue soaking each layer as you go. Or you can wait for the next rain and it will take care of it for you!

Step 6: Finishing Touches

As you reach the desired height, make sure the top layer is level and securely in place. You can also customize the look of your wall by applying a concrete sealer or painting the bags once the concrete has fully cured.

NOTE – watch out for busted bags! Once they get wet you have concrete so you need to keep them dry if this happens. We just put these in line in the wall and they still worked great. Just tape up the bag to keep it in until the concrete sets.

Benefits of Using Quickrete Bags

Using bags of Quickrete for your retaining wall is not only cost-effective, with each bag costing just a few dollars, but also simplifies the construction process. There’s no need for mixing mortar, and the bags can be laid directly in place, reducing the complexity and time needed to build your wall.

With careful planning and some elbow grease, you can construct a functional and inexpensive retaining wall using Quickrete bags. This do-it-yourself project is perfect for homeowners looking to enhance their outdoor space while sticking to a budget.
