Should I clean my retaining wall?
Your retaining wall sits outside in every weather, so does it really need cleaned?
The answer is absolutely yes! The nature of nature is growth, and when plants grow, their tiny but mighty root systems can be destructive even on retaining wall blocks. While moss can be an attractive natural addition to a retaining wall, invasive creeping vines and weeds can cause minute damage that builds up to a bigger issue over time.
Plus, a retaining wall that is protecting against erosion or drainage issues is still enduring those elements. Therefore it is vitally important to do your part to keep mildew, dirt, and plant materials at bay to best protect the value and integrity of your retaining wall.
Small changes can create big waves! A little cleaning with materials you likely already have in your home can both maintain the functionality and the beauty of your retaining wall for years to come.
What will I need?
Firstly, you will need to know the material of your wall blocks. The most common are stone, brick, and concrete.
For any type of block, experts recommend a standard garden hose with a sprayer attachment.
Cover any plants that could be negatively impacted by chemicals or moisture, and then gently spray the retaining wall until it is thoroughly soaked. You can just soak a small section that needs cleaned, or the entire wall.
How do I Clean My Retaining Wall?
Stone
Brick
Brick retaining walls require a gentler hand. Add regular dish soap to the sprayer reservoir, apply to the prepared wall, and use a toothbrush or similar soft-bristled brush to scrub areas that require greater attention. Rinse afterwards with clean water.
Concrete
Concrete retaining walls are the hardiest when it comes to cleaning. Add bleach to your sprayer reservoir and use a high setting to combat stains buildup.
