CORE Drive – Gravel Stabilisation Contractor in Buckinghamshire

Gravel is one of the most aesthetically pleasing, cost-effective, multi-purpose surfaces around, but without assistance it has a tendency to move around and end up where it shouldn’t.

CORE Drive provides a naturally porous stabilising base for the gravel to sit, ensuring it stays put! It’s inexpensive, simple to install and super effective making it the ideal solution!

CORE Drive Gravel Stabiliser

Installing CORE Drive will assure a maintenance-free, durable gravel paving surface for all types of high traffic areas be that; vehicles or pedestrians.

CORE Drive Gravel Stabiliser’s interlocking panels provide an easy installation and consist of hexagon cells to form a strong honeycomb design that holds the gravel in place. Once the gravel is laid onto the system you have an eco-friendly gravel surface costing substantially less than alternative paving options such as: blocker pavers or concrete.

The underside of the CORE Drive system resilient geotextile, permitting water to drain easily, preventing growth of weeds.

 

Benefits if CORE Drive

  • Stabilises Gravel: CORE Drive’s honeycomb design ensures gravel stays put resulting in a hassle free paving solutions with no ruts or sinking.
  • Cost Effective: Preventing gravel from moving will result in you using less and alleviating the need to frequently replenish.
  • Super strong: Enhanced load bearing causes no rutting, separating or sliding with vehicle traffic.
  • Environmentally Friendly: As a porous paving solution CORE Drive returns water back to the environment by enabling it to drain over the entire surface. In addition, the system is made up of UV, heat resistant recyclable virgin Polypropylene.
  • Alleviates Weeds: The geotextile under layer avoids weed growth
  • Attractive: When gravel fills the system, CORE Drive becomes almost unnoticeable, showcasing only the gravel surface.
  • ADA compliant: Ideal for pedestrians, bicycles, & wheelchair traffic.
  • CORE Marker: Easy to add parking lines and edge indicators
  • SUDS compliant. As CORE Drive is porous it is ideal for solutions requiring a Sustainable Drainage System.

CORE Drive FAQ’s

What vehicles can use CORE drive?

COREdrive can be used by almost any wheeled vehicle, we have grids suitable for vehicles ranging from golf buggies to fire engines.

Please do not hesitate to contact us directly to discuss the best grid for your project.

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

Is it environmentally friendly?

Yes!

COREgravel 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 COREgravel is made from pure white recyclable virgin Polypropylene (PP) or 100% recycled black PP both of which are UV and heat resistant.

Are COREdrive installations easy to maintain?

Yes!

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 COREdrive structure, you should rake the gravel to completely cover the honeycomb, thus preventing damage.

Can COREdrive be used on a driveway that has slope?

Yes!

COREdrive 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 COREdrive 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 COREdrive grid.

Does wheel-spinning damage the COREdrive grid?

Whilst some of our COREdrive grids are capable of taking HGV traffic, no plastic gravel stabilising grid on the market will withstand the excess friction caused by a wheel-spinning vehicle tyre.

It is quite difficult to prevent a slight wheel-spin when trying to pull away on a gradient that has a loose wearing course (i.e. gravel). This usually results in the surface dressing of gravel being pushed away leaving the tyre to make direct contact with the plastic grid, this in turn causes stress fractures in the cell wall and can result in a damaged grid.

How do we overcome the wheel-spinning problem?

We would recommend installing ‘traction strips’ to any area of the drive that could potentially experience a wheel spinning vehicle tyre. Quite often, vehicles accelerate sharply when joining the highway to join the traffic flow, if you have a loose wearing course this can result in a wheel spin which could potentially damage your COREdrive grid.

How do I install a ‘traction strip’?

The ‘traction strips’ need to be constructed using a hard standing material such as tarmacadam, concrete, granite cobbles /setts or block pavers. The traction strips need only be 300-500mm wide to take the width of your vehicles tyres and only need to be as long as the distance between the wheels of the vehicles.

Is there suggested speed limit for COREdrive 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 COREdrive grid. For this reason we would advise a maximum speed limit of 5mph.

Is COREdrive easy to install?

Yes!

We have a unique interlocking system and all of our grids come with a non-woven geotextile weed membrane heat-welded to the underside. Please take a quick look at our install video to see how easy it really is.

Is it SUDS compliant?

Yes.

Our products are one of the best Sustainable Urban Drainage Solutions available.

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 COREdrive 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 it 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 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 COREdrive or COREpath stabiliser is sufficiently stable to allow safe passage for all of the above named users.

What about weeds, will they grow through the gravel?

No.

The geotextile membrane material that is heat welded to the bottom of COREdrive prevents weed growth from underneath the grid.

You may however experience a few air born 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.
