Yes, leaking water can cause a house to sink. A persistent water leak under the house can undermine the foundation’s stability by washing away the soil that supports it.
Over time, this erosion can lead to uneven settling or sinking of the house, posing serious structural risks.
This blog will delve deeper into how water leaks affect foundations and what we can do to prevent them.
What Happens When Water Leaks Near House Foundations?
When water leaks near house foundations, it can lead to significant structural damage. The persistent moisture due to a water leak under the house can cause its foundations to weaken, leading to cracks and potential subsidence.
Over time, this can compromise the stability of the house, requiring extensive and costly repairs to ensure safety and integrity.
What Long-Term Damage Can Water Leaks Cause to Foundations?
Water leaks can cause the following long-term damage to foundations:
Structural Weakness and Cracking
Persistent water leaks can severely weaken the structural integrity of a building’s foundation. Over time, the continuous presence of water causes the foundation material, whether concrete, stone, or brick, to erode or deteriorate. This weakening often leads to cracks, which can be both superficial and deeply structural.
Mould and Fungal Growth
One of the more insidious long-term effects of water leaks on foundations is the promotion of mould and fungal growth. These organisms thrive in damp, poorly ventilated areas, making a leaking foundation an ideal breeding ground. Over time, mould and fungus can degrade the quality of the building materials, leading to further structural damage.
Soil Erosion and Subsidence
Continuous water leakage can lead to soil erosion around the foundation. As the soil erodes, it loses its ability to support the foundation effectively, potentially leading to subsidence.
Is House Sinking the Same as Subsidence?
Yes, house sinking is essentially the same as subsidence. Subsidence is the downward movement of a building’s foundation due to changes in the underlying soil.
Understanding what is subsidence and what it entails is beneficial in recognising its presence.
How Can I Prevent Foundation Damage from Water Leaks?
You can prevent foundation damage from water leaks by ensuring proper drainage maintenance, inspecting leaks, and installing a sump pump.
Proper Drainage Maintenance
Maintaining proper drainage around your home prevents water accumulation near the foundation. Ensure the ground slopes away from your house to facilitate water runoff, especially during heavy rains.
Gutters and downspouts should be kept clean and in good repair, directing water at least a few metres away from the house. This helps keep the soil around house footings dry, reducing the risk of water seepage and subsequent damage to the foundation.
Plumbing Leak Inspection
Regular inspections and maintenance of your home’s plumbing system can significantly reduce the risk of leaks that may harm the foundation. Pay attention to any signs of moisture or dampness in walls, floors, and ceilings, as these can indicate hidden leaks.
Promptly fixing leaks not only saves water but also prevents the gradual weakening of the foundation. It’s essential to have a professional periodically check your plumbing system to identify and address any potential issues before they escalate.
Sump Pump Installation
Installing a sump pump in areas prone to water accumulation, like basements or crawl spaces, can be a highly effective solution for foundation protection. A sump pump collects excess water in a sump pit and then pumps it away from your home. This is particularly beneficial in areas with high water tables or in homes that frequently experience basement flooding.
By keeping these areas dry, a sump pump helps safeguard the integrity of your home’s foundation against water damage.
