Material Failure
Most retaining walls are made of some combination of concrete, wood, or stone. Though structurally sound, these materials often wear down over time, especially in exceptionally wet or humid climates. Although wood retaining walls are visually striking, wood is particularly vulnerable to material failure.
Root Damage
Tree roots spread out underground, often breaking through the surface of the ground once they’ve reached a certain size. This becomes problematic when roots expand beneath your retaining wall, pushing the wall’s materials upward or outward and often causing cracks that must be repaired for the wall to maintain functionality.
Poor Drainage
Excessive moisture often causes retaining walls to develop complications related to poor drainage. If your wall appears to be bowed or leaning, it is no longer able to withstand the amount of pressure being exerted upon it. Often, this is due to a buildup of water.
Structural Issues
Structural issues arise from poor construction or the use of subpar materials. A sturdy retaining wall should have a firm foundation with a stable footing and any necessary structural reinforcements. When builders neglect to ensure its structural integrity, a retaining wall may crack, crumble, or even collapse.
