Common Failures

Why quick fixes leave the water exactly where it was

The surface is rarely the problem, the fall direction, the base, or the drainage is.

Wrong Fall Direction

A patio sloping toward the house sends every shower straight to the threshold, no matter how well the slabs sit.

Full Regrade to 1:60

The sub-base is adjusted and the surface relaid to a 1:60 to 1:80 gradient that clears water away from the building.

Settled Low Spots

Clay-heavy ground shifts seasonally, dropping the bedding sand and creating dips that collect standing water after rain.

Lift & Relay

Affected slabs are lifted, the bedding sand corrected beneath them, and the surface relaid flush with the surrounding level.

No Drain at Threshold

Where water naturally collects at one edge, there is nowhere for it to go, it sits until it evaporates or seeps under the door.

ACO Channel Drain Install

A channel drain is set into the paving at the low edge, intercepting run-off before it reaches the threshold or house wall.

Patching Over the Cause

Filling a dip with sand or mortar without correcting the base level means the same spot sinks and pools again within months.

Sub-Base Reinstatement

The sub-base is rebuilt to the correct level before any bedding or paving goes back, so the repair holds through seasonal ground movement.

Scope of Work

What patio drainage & levelling covers

From a single sunken slab to a full regrade, the work is scoped to the problem found on survey.

Slope & Level Check

Survey of fall direction and low spots before any lifting.

Run-Off Assessment

Check where water goes once it leaves the patio edge.

Drain Outlet Connection

Safe connection to soakaway or approved discharge point.

Sub-Base Reinstatement

Type 1 base rebuilt after drain or relay work.

Diagnose First

Patio drainage and levelling, find the cause before lifting a slab

Standing water on a patio is a drainage or fall problem, and the two have different fixes.

Request a Survey

The diagnostic process starts by identifying where water sits and which direction the surface falls. A patio that slopes towards the house rather than away from it will pool at the threshold regardless of how well the slabs are laid. Peterborough’s clay-heavy ground is also prone to seasonal movement, which creates low spots in the bedding sand even when the original falls were correct.

Once the cause is identified, the fix is matched to the problem. A localised low spot may need only a lift-and-relay of a few slabs with the bedding sand corrected beneath them. A surface that falls the wrong way across its full width needs regrading, lifting the affected area, adjusting the sub-base level, and relaying to a gradient that clears water at a 1:60 to 1:80 fall.

Where the ground cannot shed water fast enough, an ACO channel drain or French drain is installed as part of the remedial work. Building Regulations require surface water to be disposed of safely, discharging it onto a neighbour’s land or into a highway drain without consent is not compliant. The itemised quote covers the drain, connection and any sub-base reinstatement needed after installation.

Why Choose Us

Why choose us for patio drainage & levelling in Peterborough?

Local knowledge, a clear process and an itemised quote before any work begins.

Survey Before Any Lifting

The fall direction and base condition are assessed first, so the quote covers the actual problem.

Itemised Quotes, No Surprises

Drain, sub-base and relay are costed as separate lines, you see exactly what each part of the job costs.

Clay Ground Experience

Every survey accounts for how Peterborough’s clay soils move seasonally in the base specification.

Building Regulations Compliance

Surface water disposal is handled to meet Building Regulations, no discharge onto neighbouring land or highway drains.

Scoped to the Problem

Work is limited to the affected section where possible, avoiding unnecessary lifting of sound paving elsewhere.

Common Questions

Questions about patio drainage & levelling

  • Why does my patio keep holding water?

    Standing water is almost always caused by insufficient fall, a sunken section, or blocked drainage. Patios need a minimum gradient, typically 1:80, to shed water toward an outlet. Without it, water sits on the surface. A blocked channel or gully can cause the same result even when the fall is correct.

  • Could a small dip in my patio be causing the water to sit there?

    Yes. Even a shallow depression of a few millimetres is enough to trap water. Slabs settle unevenly over time as the sub-base shifts, creating low spots that collect rainfall. The dip itself is usually the symptom; the cause is movement in the material beneath.

  • Do I need drainage as well as levelling?

    Often both are needed together. Levelling corrects the surface fall so water moves; drainage gives it somewhere to go. If the patio is regraded but has no outlet, water simply pools at a different point. A site assessment will confirm whether an existing gully or channel is sufficient or whether a new outlet is required.

  • Can my patio be fixed without replacing the whole thing?

    In many cases, yes. If the problem is confined to a section or two, those slabs can be lifted, the sub-base corrected, and the slabs relaid to the right fall. A full replacement is only necessary when the base has failed across the whole area or the slabs themselves are too damaged to reuse.

  • Will fixing the patio sort out both the slope and the drainage problem?

    A proper repair addresses both together. Regrading the surface sets the correct fall; clearing or adding drainage gives the water a route away. Fixing one without the other usually leaves the problem partially unresolved, so both are assessed and tackled in the same job.

  • How much does patio drainage and levelling cost?

    Guide prices run from £300-£700 (Minor levelling) to £1,500-£3,000 (Levelling with sub-base rebuild). A localised repair to a few slabs sits at the lower end; a full regrade with new outlets costs more.

  • What makes the cost go up if the base or runoff needs extra work?

    Excavating and rebuilding a failed sub-base adds material and labour beyond a straightforward relay. Installing a new channel, soakaway, or connecting to an existing drain adds further cost. The larger the area that needs base work, and the deeper the excavation required, the more the overall price increases.

  • Will the problem come back if the base is not corrected?

    Yes. Relaying slabs on a failed or poorly compacted base means the same settlement will recur, often within one or two winters. The base must be excavated, topped up with the correct material, and compacted before slabs go back. Skipping that step is the single most common reason drainage and levelling repairs fail.
