Retaining walls are important in controlling soil erosion and preventing land movement. However, over time, retaining walls can become damaged and require repairs. Due to the pressure a retaining wall must withstand, these repairs can be urgent to avoid more severe damage.
Crumbling or Deteriorating Retaining Wall Material
Retaining walls are exposed to various elements such as wind, rain, and sunlight, which can cause the material to wear down, become discolored, or develop cracks and chips. Addressing this type of damage is important to maintaining your retaining wall. If you notice any signs of deterioration or damage, there are several repair options to consider. In some cases, patching or sealing the damaged areas may be sufficient, but more severe damages require replacing the compromised sections of the wall.
Damage Caused by Frost Heave
Frost heave is an issue that causes extensive damage to retaining walls and other structures. This occurs when the soil behind the retaining wall freezes. When soil gets cold enough to freeze, it expands. This expansion puts more pressure on the retaining wall. Eventually, this pressure may reach a point where it causes the retaining wall to crack and bulge.
It is possible to mitigate the risk of frost heave damaging your retaining wall. Proper construction techniques are essential for limiting this risk. A properly designed retaining wall will take into account the frost heave risk. This can allow for enough space to be left to account for this expansion. The retaining wall can also be reinforced to help support the pressure from the expanding soil.
Tree Root Damage to the Retaining Wall
Tree roots are another issue that can cause damage to retaining walls. These roots can grow into the soil behind the retaining wall. This puts additional strain on the wall and can even cause the soil to shift positions. Over time, these roots can even grow into the retaining wall, which can cause it to crumble. Once this damage occurs, a total restoration may be needed to return the retaining wall to its original condition.
Fortunately, you can prevent tree root damage to your retaining wall by following several simple strategies. An example of this is keeping trees safe from the wall. Additionally, root barriers can be installed between the retaining wall and the soil. These barriers effectively stop the tree roots from growing through them. Ensuring the retaining wall has good drainage limits this risk because it will prevent roots from being drawn to the moisture trapped behind the retaining wall.
