Welcome.

CORE DRIVE can be used by almost any wheeled vehicle, we have gravel grids suitable for vehicles ranging from golf buggies to fire engines. Please do not hesitate to contact us directly to discuss the best gravel grid for your project.

Please note, whilst some of our gravel grids are capable of taking HGV traffic loads, no plastic gravel grid available on today’s market will withstand the immense pressure and friction created by the screwing action of a large vehicle performing a static manoeuvre.

Yes!

CORE DRIVE gravel grids can be used on driveways that have up to a 20% gradient, Please see recommended grids below and their capabilities:

• CORE DRIVE 40-30 (up to a 1 in 5) 20% gradient for domestic use.
• CORE DRIVE 50-35 HD (up to a 1 in 5) 20% gradient for domestic use or shared access.

If you are planning to use CORE DRIVE on an area that has a steep gradient and it is likely that your vehicle will come to a complete standstill whilst still on the gradient, we would advise on taking the precautionary measure to install ‘traction strips’ across the driveway to help provide the initial traction required that will allow your vehicle to pull-off and accelerate on the slope without wheel-spinning.

If a vehicle loses traction on the slope and begins to wheel spin this will inevitably lead to a risk of damaging the grid. If there are any areas on the driveway where it looks like a loss of traction may be unavoidable due to design or curvature of the gravel drive, we recommend installing a hardstanding such as block paving, macadam, or similar surface to these areas to help maintain traction and preserve the longevity of your new driveway!

CORE DRIVE 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 DRIVE is made from pure white recyclable virgin Polypropylene (PP) or High Density Polyethylene (HDPE). The HDPE products are also available in 100% recycled options.

While you do not have the rutting and aggregate migration of traditional gravel installations, you still need to occasionally rake the gravel.

If you can see the CORE DRIVE structure, you should rake the gravel to completely cover the honeycomb, thus preventing damage.

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 CORE DRIVE grid.  For this reason we would advise a maximum speed limit of 5mph.

Yes!

Please take a quick look at our install video to see how easy it really is.

For best results we recommend using a 6-12mm angular aggregate as this helps the surface dressing to stay in place, and ensures an attractive surface. However, CORE DRIVE grid will work with aggregate sizes up to 20mm.

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.

Yes.

A SuDS compliant sub base build up should contain nothing smaller than 2mm in its construction, this is referred to as a  ‘no fines’ or ‘reduced fines’ build up. By using a reduced fines sub base material such as type 3 or 4-40mm clean aggregate, below a grit bedding layer, the water is able to infiltrate through the complete build up and back into the subsoil.

Whilst all of our grids are completely porous and can therefore form a SuDS  surface course, the free moving loose aggregate  layers required to form a truly SuDS compliant surface can prove difficult to compact adequately to provide a sufficiently stable sub base.

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 manoeuvre. 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.

No.

The geotextile membrane that is heat welded to the bottom of CORE DRIVE prevents weed growth from underneath the grid. You may however experience a few air borne weeds that are caused by birds dropping seeds or natural pollination; these can be easily removed due to the fact they are restricted to rooting in a single cell full of loose gravel.

Yes – if the install is carried out to our specification then there is a 15 year guarantee.

For best results we recommend using an angular aggregate up to 10mm in size as this helps to compact the aggregate into the cells effectively.

CORE PATH 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 surfaces.

An edging is not essential, but plant life bordering your pathway will grow into the edges of the gravel if there is no physical restraint.

If you prefer a clean line to your path CORE EDGE is the perfect low maintenance choice available in a 3 face heights and 7 finishes.

Yes!

CORE PATH is easily cut to shape and size. The most effective tool for this would be a disc cutter or angle grinder. Be sure to wear appropriate PPE when using these tools.

If the ground you are preparing is already firm underfoot you can simply lay 10 / 15mm of sharp sand to iron out any minor deformities in the surface, if the ground is soft or prone to becoming soft in the wetter months, a suitable hard wearing sub base should be installed to make the ground firm – such as MOT Type 1.
