# Block Paved Patios in Cambridge

![Block Paved Patios carried out by a professional patios](https://utmost-ibex-736.convex.cloud/api/storage/f50f2589-df31-4641-8b9e-267498660638)

A stable, level outdoor surface that drains properly and stays that way for years.

- **Local Survey & Quote**: The site is surveyed and the work is quoted properly.
- **No Hidden Groundwork**: Excavation, sub-base and bedding quoted as separate lines.
- **Block Paving Specified**: We specify block paving to suit the garden and the house.

## Why some block paved patios fail within a few seasons

The surface is only as good as what sits beneath it. These are the failure modes that a proper installation avoids.

- **Skipping Excavation**: Laying blocks over an existing surface leaves the old, unstable base in place, causing sinking and edge spread within a few seasons.
  **Full Dig-Out First**: The existing surface is broken out and the ground excavated to the correct depth for sub-base, bedding layer and block thickness.
- **Poor Compaction**: A sub-base tipped in one pass and not compacted in stages will settle unevenly, pulling blocks out of level and opening joints.
  **Staged Compaction**: Sub-base is compacted in layers using a plate compactor, with Cambridge clay requiring particular care to prevent later settlement.
- **Wrong Surface Fall**: Blocks laid without checking the fall can drain water back towards the house, risking damp-proof course breach and foundation damage.
  **Fall Checked at Lay**: The fall is set and verified after compaction so surface water runs clear of the house and clears the damp-proof course.
- **No Edge Restraints**: Blocks without haunched edging restraints spread outward over time, leaving gaps at the border and destabilising the whole surface.
  **Edging Set in Concrete**: Edging restraints are haunched in concrete before any blocks are placed, holding the perimeter firm for the life of the patio.

## What the installation covers

From ground preparation through to jointing, each stage is part of a single quoted job.

- **Sub-Base Preparation & Compaction**: Ground excavated to correct depth, sub-base laid and compacted in stages for a stable, settled foundation.
- **Bedding Layer & Block Laying**: Sand bedding screeded to a consistent level, blocks laid to pattern and compacted to bring the surface true.
- **Surface Drainage & Fall**: Fall set away from the house and checked against damp-proof course clearance before jointing begins.
- **Edging & Border Restraints**: Edging stones haunched in concrete around the perimeter to hold the block layout in place long-term.
- **Jointing Sand Finish**: Jointing sand brushed into gaps and locked in with a final compaction pass to complete the surface.

- **New Patio Installation**: Full dig-out and lay on bare or cleared ground.
- **Old Patio Replacement**: Break-out of worn or sinking surface, then full reinstall.
- **New Build Garden Patio**: Installation after construction, accounting for builder waste below topsoil.

## What block paved patio installation actually involves

Block paving looks straightforward, but the sub-base and edging work underneath determines whether the surface stays level.

The installation sequence starts with ground assessment. Existing surfaces are broken out, and the ground is excavated to a depth that allows for sub-base, bedding layer and block thickness. On Cambridge clay, compaction is done in stages to avoid settlement. Edging restraints are set and haunched in concrete before any blocks are placed.

Blocks are laid to a pattern on a screeded sand bedding layer, then compacted with a plate compactor to bring them to a consistent level. The fall is checked at this stage, surface water must run away from the house and clear the damp-proof course. Laying blocks over an existing slab without this preparation is a shortcut that causes sinking and edge spread.

Jointing sand is brushed into the gaps and the surface is compacted again to lock it in. Cambridge new build gardens often have compacted builder waste beneath the topsoil, which affects excavation depth and sub-base specification. The installer checks this during the survey and adjusts the quote accordingly.

## Questions about block paved patios in Cambridge

### Why is my block paved patio sinking or going uneven?

Sinking or unevenness almost always points to a failed sub-base. If the compacted hardcore or sand bed beneath the blocks was too thin, poorly compacted, or laid over soft ground, it shifts under load over time. Tree roots, poor drainage, and frost heave can also disturb the base. The blocks themselves rarely fail, it is what is underneath that moves.

### Do I need a new patio, or can this one be repaired?

If the damage is limited to a few sunken or cracked blocks with a sound sub-base beneath, repair is usually the right call. If the sub-base has failed across a wide area, or the blocks are badly weathered throughout, a full relay gives a more lasting result. A site survey will show which applies to your patio. See [patio cleaning, repointing and repair](https://www.cambridgepatios.co.uk/services/patio-cleaning-repointing-repair) for smaller fixes.

### Can you fix just part of the patio, or does the whole thing need replacing?

Partial repairs work well when the problem is confined, a localised sunken area, a damaged edge, or a handful of broken blocks. If the sub-base failure runs across most of the patio, patching one section often means another sinks shortly after. A survey identifies where the damage stops so you only replace what genuinely needs it.

### Will block paving suit my house and garden?

Block paving suits most residential properties. It comes in a wide range of colours, sizes, and laying patterns, herringbone, stretcher bond, basket weave, so it can match a traditional brick house or a more contemporary garden. The main consideration is ground conditions and drainage, which a survey will assess before any work starts.

### Will it look right with the rest of my property?

Block paving can be matched to your brickwork colour or contrasted deliberately as a design feature. Choosing the right block size, colour, and laying pattern makes a significant difference to how the finished area reads alongside your house and boundaries. Options are shown at survey, before you commit to a material.

### Can block paving work for seating areas, paths and general garden use?

Yes. Block paving handles seating areas, connecting paths, and general foot traffic well. Its interlocking structure distributes load evenly, making it durable underfoot. For paths specifically, see [garden paths and walkways](https://www.cambridgepatios.co.uk/services/garden-paths-walkways) for how the same material is specified in narrower runs.

### Can I put block paving over my old patio?

Laying over an existing surface is rarely advisable. It raises the finished level, which can cause drainage problems and conflict with door thresholds or damp-proof courses. It also hides any sub-base issues that will eventually push through. Lifting the old material and preparing the ground properly gives a far more stable result.

### What needs checking before the patio is laid?

The survey checks the existing ground level, drainage fall, soil type, and any services buried beneath the area. Boundaries, access for machinery, and proximity to the house damp-proof course are also assessed. Getting these details right before excavation starts prevents costly changes mid-job.
