Sinking Patio or Deck Traced, Corrected and Supported in Edgbaston

Sinking is a ground story. Patios settle when the sub-base was too thin or poorly compacted, when water washes fines out from beneath the slabs, or when the ground itself — fill, clay, old made-up ground — compresses over time. Decks sink when posts were set shallowly, rotted at the base, or planted in ground that moves seasonally. The surface is just the messenger.

Why surfaces sink

Water is usually the accomplice. A downpipe discharging beside a patio, a slope feeding rainwater under the slabs, or drainage that has failed will undermine a base faster than age ever will. Frost lifts and drops the ground cycle after cycle. Near trees, roots and drying clay pull the ground down too. Knowing which of these is at work decides whether the fix is local re-bedding, rebuilding a section of base, improving drainage or something bigger.

How we assess it

We look at the pattern of the sinking — one corner, a strip, the whole area — because the pattern points at the cause. We check falls and drainage around and across the surface, look at where water enters the ground, probe the edges and lift slabs or boards where needed to inspect the base or frame. If the movement looks significant or ongoing — wide cracks, rapid change, structures close by — we will recommend a structural engineer's assessment rather than guess. We would rather tell you that early than sell a cosmetic fix over a moving foundation.

What the fix looks like

Small local settlement can often be corrected by lifting and re-bedding slabs on a properly compacted base. Sections undermined by water may need the base rebuilt and the water problem dealt with at the same time — there is little point re-laying a patio that the same downpipe will undermine again next winter. Deck posts may need deepening, renewing or better support. Larger or whole-surface work is quoted as a project after the survey; a visit estimate covers a defined working day on an agreed scope, and multi-day work is staged.

Honesty about limits

We cannot guarantee against future settlement — ground that has moved once can move again, especially with our West Midlands weather. What we do is fix the cause we can find, rebuild properly where needed, and tell you clearly what risk remains. No one can promise a patio will never move; anyone who does is selling confidence, not construction.

When to call

A dip that holds puddles, a step that has appeared between slabs, or deck posts that have visibly dropped all merit an early look — the longer water works underneath, the bigger the eventual job.

Prevention worth knowing

The best protection against sinking is managing where water goes. Downpipes that discharge beside or across a paved area, gutters that overflow in heavy rain, and ground that slopes towards the surface all feed the movement you are paying to fix. When we correct your patio or deck we will point out any water sources feeding the problem, and dealing with them — even something as simple as redirecting a downpipe — often matters as much as the groundwork itself. Watch new repairs after the first few heavy rains and tell us promptly if anything moves again.

How to book

Book via maintenance-men.com or by phone. The booking fee is paid when you book, labour is hourly at a rate that depends on how soon you need us, and the full cost is quoted and approved before work starts. Helpful details: when the sinking started, whether it worsens after rain, and anything you know about the ground or the original build. Materials are quoted separately.
