Retaining Wall Installation Portland, Oregon
Retaining Wall Installation Service
Retaining walls stand firm as a line of defense between your property and everything else beyond your property line. They keep soil from sliding downward and eroding over time, mostly due to water runoff, both natural and caused by irrigation. Ultimately, it can be your home the retaining wall is protecting.
However, retaining walls are not just practical. They can also add a beautiful aesthetic element to your landscaping and additional value to your home.
They solve a variety of landscaping issues and also serve to create some great planting areas. They’re also used to hold back a slope or define a particular area of your yard.
Retaining Walls as a Sloping Yard Solution
A properly retaining wall can tame a slope and protect the rest of your landscaping from sliding debris and excess water drainage.
We take into account several things before beginning construction of your retaining wall. We must ensure your wall is sturdy enough to hold back the slope, built solidly to withstand the elements to last a very long time, and doesn’t violate any building codes. Sometimes, a call to official utility workers is warranted to have them come out and check for buried power cables and sewage lines.
Retaining Wall Aesthetics
A quality wall can add great beauty and structure to your landscaping plan. A well-placed wall can also help define the space. You may even consider integrating a patio, bench, or stairs into your wall design. This creates both functional and architectural interest.
We use a variety of great looking materials like limestone, boulders, concrete sting and keystone blocks to build your wall. These materials add charm and create a unique decorative look.
