Water pooling on a patio surface

Uneven Patio and Puddles After Rain

Every patio should be laid with a slight fall so water runs off. Where that fall is missing, reversed or interrupted, puddles form — and those puddles are where algae, staining and frost damage begin.

Ponding is worth fixing for the paving's sake, not just for comfort.

How much fall a patio needs

Around one in eighty is the usual target — barely perceptible underfoot but enough to move water reliably. It should run away from the house, not toward it.

Where a patio abuts the building it should also sit clear of the damp proof course.

Why levels drift

Poor base compaction lets areas settle unevenly, particularly on made-up ground or over old borders. Adding a patio extension without matching the original falls creates a low point at the junction.

Raised beds, walls and new steps built afterwards can also dam the runoff path.

Putting it right

Localised ponding can often be solved by lifting the affected slabs and re-bedding to a corrected level. Widespread ponding means the base needs regrading.

Where a patio sits below surrounding ground, a channel drain or gravel margin gives water a route away.

Frequently asked questions

Is a fall toward the garden always right?

It needs somewhere to go — a lawn or border that can absorb it, or a drainage channel.

Can a level patio ever work?

Only with permeable jointing and a free-draining base designed for it.

Will re-laying reuse my slabs?

Usually yes, which keeps the cost of correcting levels down.

Puddles every time it rains?

We regrade and relay patios so water goes where it should.
