Why Do Basements and Retaining Walls Leak?
In multi-residential and commercial buildings, basement walls—particularly those forming underground car parks—and retaining walls are under constant pressure from surrounding soil and groundwater. Over time, this pressure can compromise the structure, leading to leaks that have the potential to affect the overall integrity & safety of the building.
Here’s some of the most common causes of water leaks we see in retaining walls and basement carparks throughout South East Queensland:
Hydrostatic Pressure
Heavy rainfall or poor drainage can cause water to accumulate around basement walls and retaining structures. The resulting hydrostatic pressure forces water through even the smallest cracks or joints in the concrete.
Cracks and Movement
Over time, settlement, vibration from traffic, or construction defects can cause structural cracks. These weak points allow water to penetrate the basement wall or seep through retaining walls, especially under pressure.
Inadequate Drainage Systems
Without proper subsoil drainage—like ag/slotted coil drains or functioning waterproofing membranes—water can build up behind retaining walls or around basement walls, leading to persistent seepage or leaks.
Failing or Missing Waterproofing
Many older commercial and apartment buildings in Southeast Queensland either lack modern waterproofing systems or have membranes that have deteriorated over time. Once a membrane fails, water ingress is inevitable.
Poor External Grading
If the surrounding ground slopes toward the structure, water is naturally directed toward basement walls or behind retaining walls, adding further pressure and increasing the likelihood of leaks.
Blocked or Damaged Stormwater Infrastructure
In many cases leaking basement walls are the result of failed or blocked stormwater drains, downpipes, or overflow systems that redirect water toward the foundation rather than away from it.
