Professional Retaining Wall Builders in Andover, MN

Retaining walls are known for their functionality within your outdoor space, especially if your property features steep terrain. They also provide erosion prevention and redirect the flow of water while simultaneously creating flat areas within your landscape that can be great for planting beds or a space to install turf to make mowing the lawn easier. 

Our Retaining Wall Build Process

1. Site Assessment and Planning – The opening phase of a retaining wall project is meeting with a member of our team to discuss your project and take measurements of the location for your new wall. We then take your ideas and requests for colors, styles and material types and compile them with the dimensions (height and length) of the wall and present a proposal with the price for the project.

2. Excavation and Base Preparation – After agreements are signed and deposits are made, we place your project onto our schedule. On the arrival day, our crew gets to work beginning with excavation of the area where your wall will be built. It is dug deep enough to ensure the foundation of your wall is solid and will withstand the wide range of Minnesota weather. Next, we add base material (class 5 gravel) and continually compact it until it’s at a depth of at least 4″-6″ or more, depending on the scope of the project.

3. First Course and Stacking – After the base is compacted and prepared thoroughly, our crew begins laying the base course block (or stacking and fitting boulders with our machinery). This phase is crucial for the structural integrity of your wall when using manufactured block. Each block on the first course must be perfectly level along the entire length of the wall. Once the base course is squared away, we begin stacking the next course and placing pins or glue (depending on the block style) in each one. During this process we stagger the block to ensure there are no gaps and place the block at their designated offset to ensure the wall is slightly focused towards the slope behind it. 

4. Finishing Work and Final Walk Through – Once the wall is completely stacked and any necessary block cuts have been made, the top course of capstones are placed and glued to give your new wall a refined appearance. Depending on the slope, other terrain and native soil type, drainage pipe may be placed in or behind the wall as our crew backfills compacted soil or gravel behind the wall to ensure it stays put for years to come. Lastly, our crew will complete any landscaping near the newly built wall, add black dirt and sod, etc.
