Boggy Lawn & Wet Patches — What's Causing Them?
Persistently wet patches or boggy areas in your lawn that don't dry out after rain often indicate a broken drain leaking underground.
Persistently wet patches or boggy areas in your lawn that don't dry out after rain often indicate a broken drain leaking underground.
All lawns get wet after rain — but a healthy lawn drains and dries within a day or two. If you have a patch that stays soft, soggy, or wet for days after rain, or that's wet even when it hasn't rained, something is adding water to the ground at that location.
A leaking stormwater or wastewater drain is one of the most common causes. Underground pipes carry significant water volumes. Even a small fracture leaks enough to saturate a large area of soil over time.
A persistently boggy area is easy to live with until it isn't. Saturated soil beneath foundations causes ground movement and structural damage. A CCTV inspection will locate the leak, confirm its severity, and give you repair options before the damage spreads.
Learn About CCTV InspectionA cracked drain pipe leaks water into the surrounding soil with every flush or rainfall event. Over time this saturates the ground above and around the break.
Pipe joints that have separated due to ground movement or age allow water to escape into the surrounding soil at the joint location.
Tree roots that have entered and damaged a drain create leakage points. The same roots that cause the problem often mark the location with particularly lush growth above.
A fully collapsed drain section holds water rather than moving it. This creates concentrated ground saturation above the collapse point.
Mains water or pressure sewer connections can fail underground, creating high-volume leakage that saturates ground rapidly.
Older properties with soakage pits or French drains that have failed can cause surface saturation as water has nowhere to go.
Not always — it could also be a high water table, poor surface drainage, or an irrigation leak. But a CCTV inspection will quickly confirm whether an underground drain is contributing. It's the most reliable way to rule drainage in or out.
A wet patch that changes location with rainfall is more likely to be a surface drainage or grading issue. A fixed wet patch that's always in the same location, or that appears without rain, is more indicative of an underground leak.
Yes — this is one of the primary structural risks of drainage failure. Saturated soil beneath foundations causes differential settlement, foundation movement, and ultimately cracking and structural damage. Early identification and repair is significantly cheaper than remediation.
