Why Is My Garden Sinking?

If parts of your garden are sinking, dipping, or developing soft spots, a collapsed drain is one of the most common causes. When a pipe collapses underground, soil washes into the void through the broken pipe, and the ground above gradually subsides. This problem gets worse over time and needs professional investigation.

What to Look For

• Depressions or dips appearing in the lawn
• Paving slabs sinking or becoming uneven
• Soft, spongy ground when walked on
• Visible holes or voids forming
• Waterlogged patches in specific areas
• Unusually green or lush grass in one spot

How We Diagnose the Problem

We use CCTV surveys to inspect drains running beneath the affected area and ground investigation to assess the extent of soil washout. Drain tracing confirms the exact pipe route under your garden so we know exactly where the problem is.

How We Fix It

We excavate the collapsed section, replace the damaged pipe, and backfill with compacted material to stabilise the ground. The garden surface is reinstated as part of the repair. For ongoing subsidence risk, we may recommend relining adjacent pipe sections.
