Cracked or Damaged Blocks – Individual blocks or panels may crack due to shifting soil or water pressure, requiring replacement or patching.
Leaking or Blocked Drainage – Proper drainage is crucial for wall stability; any blockage or leaks can lead to water buildup, weakening the structure.
Tilt or Lean – If the wall tilts or leans due to soil pressure or improper installation, it may need to be straightened and reinforced.
Cracked Concrete – Concrete walls may develop cracks over time, requiring repairs to prevent further damage or erosion.
Loose Stones or Blocks – Stone or block walls can have loose sections that need resetting or replacement to maintain structural integrity.
Foundation Shifting – If the foundation has shifted due to soil movement or water erosion, the wall may need to be re-levelled and reinforced.
Sagging or Bulging – Walls that sag or bulge can be caused by poor drainage or excessive weight, requiring structural reinforcement.
Corroded Metal Components – For walls that include metal elements (like reinforcements or gabion baskets), corrosion may occur and must be addressed.
Weakened Support Structures – Any supports that have been damaged or eroded (such as timber posts or anchors) may need to be replaced or strengthened.
Moss, Mold, or Algae Growth – Over time, organic growth can weaken the wall’s surface or look unsightly, requiring cleaning or treatment.
