Hertfordshire Driveway Guide — Stevenage
Block-Paving Driveway Guide — Stevenage, Hertfordshire · SG1, SG2
What makes a block-paved driveway last on local ground — sub-base, edging, drainage and SuDS.
Most Stevenage driveway callouts we get are the same story: sunken blocks near the crossover, movement at the edges, weeds through the joints. All three trace back to build spec, not brick choice.

How long a Stevenage driveway takes
Standard 30–60sqm block-paved driveway in Stevenage runs 5–10 working days on site once any dropped-kerb application is through. We price sub-base, drainage and edging as separate line items so you can compare quotes on real spec, not a headline square-metre rate.
Ground and dig-out in Stevenage
Chalky boulder clay dominates Stevenage's geology, but extensive 20th-century earthworks across the New Town mean made-ground is common — we always test before structural work. On Stevenage driveway builds we dig to a formation that will actually support a vehicle load — typically 200–250mm below finished level for cars, deeper if the ground is soft or if any van or trailer will use it. Skip that and you'll have ruts inside two years.
SuDS and surface-water drainage
Since 2008 any front driveway over 5m² in England needs to either use permeable paving or drain to a soakaway on plot — not to the highway. That still catches out Stevenage homeowners re-paving over an old drive; a soakaway or permeable spec is designed in from the start.
Edging, kerbs and the crossover
Stevenage Borough Council protect the Old Town High Street Conservation Area carefully, and several New Town estates carry restrictive covenants on front elevations. A Stevenage driveway needs a proper haunched-concrete edge on every side or the blocks migrate outwards under load. The crossover — dropped kerb from Hertfordshire Highways — is a separate application and permit, and worth getting in early so it doesn't hold the finish up.
Local checklist for Stevenage
- Check whether you need a new dropped kerb from Hertfordshire Highways
- Confirm the drainage route — permeable paving or soakaway
- Dig to formation, not a nominal depth — Stevenage ground varies
- Haunch every edge in concrete before laying
- Pick blocks for the property era — old streets vs new estates want different formats
- Compact the sand bed and joints in stages, not one hit
Common mistakes we see in Stevenage
- Laying over an existing tarmac base without checking for movement underneath
- Skipping haunched edges — blocks always creep outwards without them
- Discharging front-driveway water to the road — non-compliant since 2008
- Under-spec sub-base on Hertfordshire clay — sunken tracks within two winters
FAQs — block-paving driveway guide in Stevenage
Do you cover Knebworth from Stevenage?
Yes, Knebworth and the surrounding villages sit in our coverage along with the main Stevenage districts.
Are 1960s Stevenage foundations strong enough for an extension?
Sometimes — they need verifying. We trial-pit and either bridge or replace rather than rely on a footing that doesn't suit modern loadings.
How long will a properly built Stevenage driveway last?
A driveway built to spec — full formation, haunched edges, correct drainage, correct sub-base — should sit tight for 25 years plus with only sand-joint top-up every 3–5 years.
Do I need permission for a new driveway in Stevenage?
You don't need planning for the driveway itself in most Stevenage cases if it's permeable or drains to a soakaway, but you do need Hertfordshire Highways permission for any dropped kerb or crossover.
