If your home is located on a piece of property that has a steep incline, then you know the importance of creating a retaining wall to prevent soil from sliding down onto your home over time. Many retaining walls are made from rock materials to give them strength and aesthetic beauty. Eliminating rock fall in your retaining wall is critical when it comes to ensuring the wall is capable of doing its job properly.
Here are three things that you can do to help stabilize your rock retaining wall in the future.
1. Install some rock bolts.
Rock bolts can serve a valuable purpose when it comes to stabilizing your rock retaining wall. Rock bolts are designed to help alleviate stress from the surface of the rock wall, and transfer it to the more stable interior of the rock mass used to create your wall.
These bolts work by drilling a hole through the surface of your retaining wall and placing a long bolt designed to fasten into a stone surface. The deep bolts create structural stability when they are installed in a pattern that minimizes rock fall and maximizes the strength of your rock retaining wall.
2. Ensure proper drainage.
One thing you must do in order to prevent your rock retaining wall from collapsing over time is ensure that the soil holding the retaining wall in place remains firm. This can be accomplished by taking the time to ensure there is proper drainage so that the soil isn't at risk of eroding away.
You can add a layer of gravel behind an underneath your rock wall to aid in water drainage, or you can add a toe drain system behind your retaining wall if you live in an area that receives a lot of precipitation. Proper drainage is critical when it comes to stabilizing your rock retaining wall.
3. Keep your retaining wall short.
The height of your retaining wall plays a critical role in determining its risk of rock fall. Short retaining walls can easily be secured without the use of anchors or additional reinforcements.
If the sloped area on your property requires a retaining wall greater than three or four feet in height, consider installing a series of shorter rock retaining walls to create a terraced effect on the slope. This will provide maximum control without requiring you to invest in anchors or cantilevers for your retaining wall.
Be sure that you are taking the steps necessary to stabilize your rock retaining wall to prevent rock fall and other types of structural failure in the future. Contact a company like Geotech Solutions Inc for more details.
