Engineered driveway construction. Designed to BS 7533 principles.
Our full engineered build-up — survey, ground engineering report, SUDS-compliant permeable sub-base, engineered edge restraints and approved UV-stable surface systems. The construction methodology beneath every Hinchliffe driveway.
Every Hinchliffe driveway is built on the same construction methodology: the Hinchliffe Engineered Surface System™. It's what separates a premium driveway from a cheap one — and it's the reason ours stay flat, drain properly and hold their line long after cheaper installs have rutted, sunk or ponded.
The surface changes — resin, block, tarmac, commercial — but the engineering underneath doesn't. Designed to BS 7533 principles, delivered by our own trained crews, backed by a fixed written quotation and a 5-year workmanship guarantee.
Six engineered layers. One driveway that lasts.
Every Hinchliffe Engineered Surface System™ install is built up in the same six stages — designed to loading, ground conditions and drainage before a single stone is laid.
1. Survey & ground engineering report
CAT4 utility scan, level survey and a written sub-base and drainage strategy designed to loading, subgrade CBR and existing ground conditions — not a fixed 100mm assumption.
2. Excavation & formation
Excavation to engineered depth, muck-away, and a proof-rolled formation. If the subgrade is soft, we specify a geogrid or capping layer before the sub-base goes in.
3. Geotextile separation
Non-woven geotextile membrane separating subgrade from sub-base — stopping fines migrating up and locking the structure together for the long term.
4. SUDS-compliant permeable sub-base
Engineered Type 3 open-graded stone for resin (fully permeable, SUDS-compliant) or Type 1 MOT for block and tarmac — placed in correct lifts and compacted to specification.
5. Edge restraint & containment
Haunched concrete edge restraints, kerbs and transitions engineered to stop lateral movement — the single biggest failure mode on non-engineered driveways.
6. Approved surface system
UV-stable Vuba resin, Brett block or hot-lay tarmac installed by our own trained crews — never subcontracted. Backed by manufacturer warranty plus our 5-year workmanship guarantee.
Why the engineering underneath decides how long the surface lasts.
BS 7533 is the British Standard for structural pavement design. Its principles govern every layer beneath a Hinchliffe surface — because cracking, ponding, sinking wheel tracks and lifting blocks almost always trace back to one thing: the layers underneath weren't engineered.
Designed for the load, not guessed
Sub-base depth and construction are specified to actual vehicle loading and subgrade — not a one-size-fits-all default.
Correct laying course & bedding
Blocks and stone are laid on the correct bedding and jointing materials — not sharp-sand shortcuts — so units lock together and resist rocking.
Falls, drainage & interception
Levels, cross-falls and linear or point drainage are designed in from the survey stage. Water is directed, never left to find its own way.
Compaction to specification
Each layer is placed at the correct depth and compacted with the right plant — the hidden cause of settlement on cheap installs.
Every Engineered Surface System™ install includes:
- Vuba Approved Installer

- CAT4 utility detection before excavation
- Designed to BS 7533 principles
- SUDS-compliant permeable build-up (resin)
- Fixed written quotation — no variations
- Fully insured
- 5-Year Workmanship Guarantee
Premium, done-once installation.
The Hinchliffe Engineered Surface System™ (full build) is typically £240–£280 per m² in resin. Our Engineered Resin Overlay System on a sound, well-draining existing base is typically £140–£170 per m². Every project is surveyed before we issue a fixed written quote.
Common questions about engineered driveway construction.
What is BS 7533 and why does it matter for my driveway?
BS 7533 is the British Standard for designing and installing structural pavements. It governs how each layer beneath your driveway is specified — from excavation depth and sub-base type to bedding, edge restraints, drainage and compaction. A driveway built to BS 7533 principles is engineered to carry the expected load and shed water properly, rather than guessed on site.
Does BS 7533 apply to resin bound driveways?
Yes. While BS 7533 is often referenced for block paving, its core principles — correct sub-base, drainage, edge restraint and compaction — apply to any pavement carrying vehicle loads, including resin bound. We build resin drives on an engineered SUDS-compliant Type 3 permeable sub-base with geotextile separation and haunched edges, all designed to the same structural principles.
What makes a driveway SUDS compliant?
A SUDS-compliant driveway allows rainwater to infiltrate naturally rather than running off into drains. For resin drives this means a permeable surface on an open-graded Type 3 permeable sub-base, sometimes with additional drainage design. Done correctly, front-garden driveways over 5 m² usually don't need planning permission.
Why does a permeable driveway last longer?
Permeable construction prevents water from sitting on or under the surface. Standing water weakens the sub-base, encourages freeze-thaw damage and causes the edges to lift. By engineering water through the structure, a permeable driveway stays structurally sound and visually cleaner for decades.
Do all driveway contractors build to BS 7533?
No. Many install to a fixed habit — 100mm of Type 1, sharp sand bedding, no geotextile, minimal edge restraint. That may look fine at first, but it often fails within a few winters. BS 7533 is the engineering standard that separates a premium driveway from a cheap one.
What does the ground engineering report include?
We carry out a CAT4 utility scan, level survey and assessment of subgrade strength (CBR) and drainage. We then write a sub-base and drainage strategy that matches your actual loading, ground conditions and existing levels — not a generic specification.
Will a BS 7533 driveway stop sinking and cracking?
It dramatically reduces the risk. Most sinking, cracking, rutting and lifting is caused by the layers underneath — poor sub-base, no drainage, weak edges or under-compaction. Designing and building to BS 7533 principles addresses each of those failure points.
How long will a Hinchliffe engineered driveway last?
On a correctly engineered base, a resin bound surface can last 20+ years, a tarmac surface 15–20 years and quality block paving 25+ years. The 5-year workmanship guarantee covers the installation; manufacturer warranties cover the approved systems we use.
The Engineered Surface System™ — your questions.
What is the Hinchliffe Engineered Surface System™?
It's our full engineered driveway build-up — survey, ground engineering report, excavation, geotextile, SUDS-compliant permeable sub-base, engineered edge restraints and an approved UV-stable surface, delivered by our own crews and backed by a 5-year workmanship guarantee. It's designed to BS 7533 principles so the driveway carries load, sheds water and stays true for decades.
How is it different from a standard driveway install?
Most driveways are built to a habit — a fixed sub-base depth, sharp-sand bedding and whatever edging fits. We engineer each layer to your ground, your loading and your drainage, and we bond that specification into a fixed written quotation. Nothing is guessed on site.
Does it cost more?
Yes — typically £240–£280 per m² for the full Engineered Surface System™ in resin, versus £140–£170 per m² for our Engineered Resin Overlay System on a sound existing base. The premium buys a driveway that doesn't rut, pond, sink or need re-laying in five years.
Is it available for tarmac and block paving too?
Yes. The Engineered Surface System™ is the construction methodology beneath every Hinchliffe driveway — resin, tarmac, block paving and commercial. The surface changes; the engineering underneath doesn't.
