CORE COMMERCIAL - Gravel Stabiliser for car parks, access road and caravan parks

fire-engineCORE Commercial grids have been specifically developed to withstand heavy commercial traffic. This is 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.

Whether you are looking to create a fully SuDS compliant build up or simply a low cost, free draining area capable of withstanding heavy traffic movement. CORE Commercial grid is the perfect low cost, wearing course.

Suitable for all types of traffic

Aggregate size

We recommend filling the CORE commercial grid with an angular aggregate up to 20mm in diameter. Note that the smaller the aggregate the flatter it will lay in the grid. If you are looking to cover an area that will be accessed by wheelchair users up to 12mm aggregate will be more suitable.

The CORE Commercial grid is designed as a level fill product. Unlike our other CORE Drive grids we recommend only filling to the top of the cell wall. This means the grid will still be seen once filled providing a practical hard wearing surface.

The perforated HDPE base eliminates the risk of gravel migrating under the cell wall whilst evenly distributing the traffic load.

CORE COMMERCIAL - Perfect for SuDS compliant build up

cc-cCORE Commercial grid is ideal for projects where a SuDS compliant surface is required.  The perforated HDPE base provides maximum stability whilst allowing the water to flow freely through the surface course.

The optional moulded ground spikes improve the structural integrity when grit is used as a bedding layer which is typically required to achieve a truly SuDS compliant sub-base.

By using a reduced fines subbase material such as type 3 or 4-40mm clean aggregate, below the grit, the water is able to infiltrate through the complete build up and back into the subsoil. 

WHAT VEHICLES CAN USE 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.

IS CORE COMMERCIAL ENVIRONMENTALLY FRIENDLY?

Yes!

CORE Commercial provides a porous paving solutions 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.

ARE CORE COMMERCIAL INSTALLATIONS EASY TO MAINTAIN?

Yes!

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.

CAN CORE COMMERCIAL BE USE ON AREAS THAT ARE SLOPED?

Yes!

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.

IS THERE A SUGGESTED SPEED LIMIT FOR CORE COMMERCIAL GRIDS?

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.

IS CORE COMMERCIAL EASY TO INSTALL?

Yes!

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 between 250-300m2 per day. As this grid has a perforated HDPE base it does not come with a geotextile membrane, we can supply this separately if you require one.

WHAT TYPE OF GRAVEL SHOULD I USE?

For best results we recommend using an angular aggregate as this helps the surface dressing to stay in place.

Your finished Core Drive will consist of hundreds if not thousands of small cells full of loose aggregate. 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.

IS CORE COMMERCIAL SUDS COMPLIANT?

Yes

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.

IS CORE DRIVE SUITABLE FOR WHEELCHAIR USERS (DDA COMPLIANT)

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 maneuver. 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 a CORE Drive or CORE Path stabiliser is sufficiently stable to allow safe passage for all of the above named users.

SUDS COMPLIANT INSTALLATION

Truly SuDS Compliant Build Up

 If you are looking to create a truly SuDS compliant surface the diagram below indicates the typical build-up you would require.

CCSUD

RETROFIT INSTALLATION

 Retrofit Build Up

CORE Commercial can be installed over existing hard surfaces such as tarmac, concrete, an old gravel driveway or a well compacted sub-base. On these installations we would recommend a 10mm bedding layer of sand under a CGSMT1000 membrane and then the CORE Commercial grid.

HOW TO LAY THE PANELS

 Laying Pattern

This picture illustrates the staggered laying pattern of the CORE Commercial grid. A 10mm gap should be left around the perimeter to allow for expansion and contractions during extreme weather conditions.
