CORE COMMERCIAL is an interlocking gravel-stabilisation grid developed for commercial car parks, access roads and high-use public landscapes. It creates a controlled, permeable gravel surface over a correctly designed supporting build-up.

CORE COMMERCIAL
Heavy-duty gravel stabilisation for commercial and public projects.
- Grid material
- HDPE
- Nominal depth
- 30 mm
- Cell width
- 75 mm
The connected cellular panels restrain angular gravel and spread surface use across the prepared bedding and sub-base. The perforated base allows water to pass into the drainage construction below.
Choose CORE COMMERCIAL where regular commercial traffic, larger installation areas or a visible, filled-level grid make it more appropriate than a membrane-backed driveway product.

Technical data
Verified specifications.
CORE COMMERCIAL 75-30 is the verified current range name. Material and cell dimensions are consistent; public sources conflict on the sheet length and width, so the order format must be confirmed on the current quotation.
Sheet dimensions require controlled confirmation

Selection
Choose it for the right reasons.
- Regular commercial vehicle use
- Large permeable gravel areas
- Projects needing positive panel-to-panel connection
- Parking and access where the gravel finish must remain controlled
Limitations
Check the interfaces.
The product does not replace formation, sub-base, drainage or edge-restraint design.
Static turning, wheel spin, braking, gradient and concentrated loading must be reviewed for the actual traffic.
Accessibility and SuDS performance depend on the completed surface and full build-up, not the grid alone.
Installation overview
Build it in the right sequence.
- 01
Prepare and compact the project-designed formation and sub-base; add geotextile or geogrid only where specified.
- 02
Install continuous edge restraint and a uniform compatible bedding layer.
- 03
Lay panels on the bedding, engage QuickLock connections and cut cleanly around interfaces.
- 04
Fill cells completely before trafficking and compact the compatible angular aggregate.
- 05
Top up to the published fill level and inspect edges, transitions, markers and turning areas.
Use the current exact product document, approved project detail and site inspection plan.

Straight answers
CORE COMMERCIAL questions.
How is CORE COMMERCIAL different from CORE DRIVE?
CORE COMMERCIAL is the heavy-duty, open-base route for commercial parking, access and public projects. CORE DRIVE is a membrane-backed gravel system with variants selected around driveway and shared-access conditions. Traffic and turning behaviour should decide the product, not appearance alone.
Does CORE COMMERCIAL include a geotextile membrane?
The commercial grid has a perforated base rather than an attached geotextile. A separate CORE geotextile may be included elsewhere in the build-up when separation or filtration is required.
Can CORE COMMERCIAL form part of a SuDS surface?
Yes, it can form the permeable surface layer. The formation, sub-base, bedding, outlets and infiltration or discharge route still determine how the complete SuDS construction performs.
