CORE COMMERCIAL.

CORE COMMERCIAL can be used by almost any wheeled vehicle, ranging from golf buggies to fire engines. This grid has been specifically developed to withstand heavy commercial traffic. It’s the ideal gravel stabilisation system for car parks, access roads and caravan parks. The perforated HDPE base means you can achieve maximum strength and stability without affecting the porosity of the surface.

This grid will withstand HGV through traffic however please note, no plastic gravel stabilising grid available on today’s market will withstand the immense pressure and friction created by the screwing action of a large vehicle performing a stationary manoeuvre.

CORE COMMERCIAL provides a porous paving solution which returns water back to the environment where it belongs instead of pooling or causing the flooding problems of traditional driveway surfaces. In addition CORE COMMERCIAL is made from pure white recyclable High-Density Polyethylene (HDPE) or 100% recycled black HDPE both of which are UV and heat-resistant.

Unlike our CORE DRIVE grids, the CORE COMMERCIAL grid is designed to be filled level with the cell wall and therefore will be seen once installed. The main advantage of this means there is even less maintenance required as there is no surface dressing to re-distribute, however, this doesn’t mean that you can’t overfill the grid slightly to make it more aesthetically pleasing if you wish.

CORE COMMERCIAL grids can be used on driveways that have up to a 20% gradient, which is equivalent to an 11-degree angle or a 1 in 5 fall.

If you are planning to use CORE COMMERCIAL on an area that has a steep gradient (15-20%) and it is likely that your vehicle will come to a complete stop whilst still on the gradient it would be prudent to install ‘traction strips’ to allow your vehicle to accelerate on the slope without wheel-spinning and damaging the grid.

In theory there is no suggested speed limit. However if you were to break sharply the friction caused by the skidding vehicle would be similar to that of a wheel-spinning vehicle. This could potentially damage the grid.  For this reason we would advise a maximum speed limit of 5mph.

CORE COMMERCIAL has a unique interlocking system that varies from our regular CORE Drive grids. This system makes it ideal for large applications as we would expect two competent contractors to lay 500m²+ per day on a prepared base (grid laying only; output depends on layout, cutting and site conditions). Since this grid has a perforated HDPE base it does not come with a geotextile membrane, we can supply this separately if you need one.

For best results we recommend using a 6-12mm angular aggregate as this helps the surface dressing to stay in place.

Smaller stones may get stuck in car tyres. Max size 20mm.

This unique design prevents the aggregate from shifting or over compacting, allowing the surface dressing of aggregate used to cover the cells and bite into the loose aggregate contained in the cellular structure, greatly reducing the amount of movement in the finished surface.

Our gravel stabilising grids are one of the best Sustainable Urban Drainage solutions available. If you are looking to create a fully SuDS compliant build up with reduced fines materials CORE COMMERCIAL is the perfect grid as it has a perforated HDPE base which means it is better suited to gravel beddings. Please see page 4 of the CORE COMMERCIAL specification sheet for a full illustration of how a SuDS compliant build up can be achieved.

With regard to local government approval of our system there is no such document or set standard in the UK with reference to disabled access, which is why we refer to the American version in our literature where we have obtained U.S. approval.

In the UK Governments approved document, part M “access to and use of buildings” it states that the surface of an approach available to a wheelchair user should be firm enough to support the weight of the user and his or her wheelchair and smooth enough to permit easy manoeuver. It should also take account of the needs of stick and crutch users.

Loose laid materials such as gravel and shingle are considered unsuitable for the approach. However we have proven through video footage and case study that loose aggregate laid in CORE COMMERCIAL stabiliser is sufficiently stable to allow safe passage for all of the above named users.

Yes – When installing CORE DRIVE, CORE PATH or CORE COMMERCIAL, installation requires the grid to be surrounded and supported by a suitible eding. Installation without an edging can potentially allow the grid to slip out of place, lift and overall get damaged. An Edging is required to secure our guarantee on our gravel grid systems.
