What is it?

 

Resin bound stone is a new and effective way of providing a highly aesthetic surface for your home or business premises. It can be installed internally or externally to provide a surface that is both very robust and load bearing, but also fully permeable. This means that any water that hits the surface will freely drain through the resin bound topping and through the EcoGrid base system to naturally dissipate in to the water table.  

These types of surfaces have an obvious advantage in current times as they are free draining and therefore effectively add to flood risk prevention. A resin bound surface is SuDS compliant and requires no planning permission; an important fact with the newly introduced surface water regulations.  

Resin bound stone should not be confused with resin bonded stone. Bound means in simple terms, that the pieces of aggregates and fines are firmly adhered together with a highly robust bonding system which actually has 20% voids, thus allowing water and fine detritus to pass freely through.  

In the past, resin bound stone was floated over a variety of sub-bases such as porous asphalt, tarmac or shredded rubber. Whereas these are perfectly acceptable sub-bases, they are not very environmentally friendly, difficult to lay, very costly and require a high skill set to install.  

The EcoGrid system employs patented EcoGrid as the permeable, load bearing base. This is a product that is made from completely recycled materials and has a load bearing capability up to 800 tonnes per square metre. The grids carry a patented locking mechanism that is unique to this product and ensures that once the grid is locked in place, it stays in place. The grid system has a low surface area of exposed plastic, allowing a strong bond between the stone infill and the resin bound surface.   

 

Excavation can be from as little as 180mm for standard vehicle domestic applications meaning that there are a number of inherent advantages: Less excavation therefore less waste to landfill and quicker preparation; Less requirement for hard-core; Swift installation of the entire base system at 100 metres per man per hour; No down time due to inclement weather as the base can be laid in the wet, No inconvenience to clients as the grids are immediately load bearing.  

        A type 3 reduced fines or clean sharp angular stone hard-core base to ensure maximum permeability and strength is laid to required depths (generally 60-100mm for domestic driveways).  

        A membrane layer is laid on the top of the hard-core layer, this stabilises the ground, stops weed growth, stops the migration of the sub-base and acts as an important hydrocarbon filtration layer.  

        A thin (10-20mm) sharp sand or fine clean stone screed is laid on the membrane to ‘bed in’ the grids. 

        The grids are laid and curves are put in place with our unique curving unit as required.  

        The grids are filled with the same sharp angular stone as the screed layer.  

        Once the EcoGrid is laid, any shapes or angular cuts can be put in with a standard angle grinder. Our EcoGrid clip and fix edge system will provide an easy guide for the required depth of resin bound stone to ensure maximum cost-efficiency for the installation. The edge is fitted by drilling through both the edge and the grid then push-fitting the required anchor fixings from both sides.  

        The EcoGrid resin system is mixed in an industry standard force mixer and then floated over the top of the filled grid. Our resin is fully UV stable 

        Levels of depth of the resin bound system are maintained with the edge detail.  

        It is a simple matter to get shapes and patterns by cutting through EcoGrid to the bottom and slotting in the flexible edge. 

Our resin needs no activator and is stronger than most; you get a ratio of resin to aggregate of 7KG to 125 KG (5 x 25kg bags) of dried aggregate. This ratio of resin to stone allows for more cost-effective installations, since up to 16% less aggregate is required for standard installations.  

We sell:

  • The Ecogrid approved quality membrane
  • An appropriate Ecogrid for your loading (Usually e40 for most resin bound stone applications)
  • An easy to clip and fix flexible edge system that gives a great level guide around the perimeter of the job
  • The two part resin in tubs of 7kg
  • A range of bagged and washed aggregates

You buy locally (Because it is cheaper for you!)

  • The harcore base (Usually type 2 with clean stone mix or type 3 reduced fines)
  • The fine stone needed for the grid infill

OK so how do I do this?

We will give you a delivered price for all that you need and swiftly dispatch the goods direct to site, they come on a tail lift vehicle and by use of a pallet truck, are carried to the site edge ready for use.

Penultimately, why Ecogrid for resin bound stone?

OK, so how long have you got? allow us to summarise

  • Less excavation
  • Stronger load distribution
  • More permeability
  • Easy to fit
  • No messy tarmac tools
  • Tarmac is NOT environmentally friendly

Lastly: Why Ecogrid and not the slightly cheaper ones out there?

You have to be careful when you are laying an acrylic bound system on top of some plastics. PP or HDPE products expand at different rates to the resin bound surface causing shifting, cracking and buckling issues. On top of this, a lot of the cheaper grid products dont lock properly together and cannot really take the loading that you read on the blurb. Essentially, they will separate and crack causing low or soft spots in your installation. With the expansion of e commerce sites, you are bound to get individuals selling products to whoever for whatever with the assurity that if and when things go wrong they can dissapear quickly avoiding the consequences. Buyer beware:

  • Check the grid credentials over a minimum of five years
  • Ask and authenticate a minimum of five installation examples
  • Look for trade credentials of the seller
  • What guarrantees are offered?

Ecogrid and resin bound stone....there is NO alternative!

Excavation is as little as 180mm for standard vehicle domestic applications meaning that there are a number of inherent advantages:

  • Less excavation therefore less waste to landfill and quicker preparation
  • Less requirement for hard-core
  • Swift installation of the entire base system at 100 metres per man per hour
  • No down time due to inclement weather as the base can be laid in the wet
  • No inconvenience to clients as the grids are immediately load bearing
  • Installation of Ecogrid as the base system requires no specialised plant or machinary
  • Installation of Ecogrid as the base system is cheaper that Tarmac or Asphalt

Once the Ecogrid is laid, any shapes or angular cuts can be put in with a standard angle grinder, the grids will cut at walking pace.

Where can it be used?

The surfacing can be used for all areas that either require a load bearing, aesthetic and very permeable surface up to a maximum loading of 7.5 tonnes.

How to?

We sell the system in kit form to make things easy, although clients are free to take all or parts of the kits as they deem fit.

Our advised thickness of resin bound surfaces are 20mm although for pedestrian trafficked surfaces, the thickness can be reduced and consequently the amount a mix will cover. Our UV stable resins come in a 2 part volume in tubs, suitable for a coverage of 3.5 square metres. Aggregate required for this resin would be 4.9 bags of clean and dry suitable sized aggregate.

Resin bound stone should always me laid when combined in a specialist force mixer to ensure correct and even distribution.


For full fitting instructions, please see our installation guidelines. Ecogrid limited advise that surfaces should always be laid by a suitably qualified installation company. Ecogrid accept no responsibility for surfacing laid outside of company guidelines.

Options?

We offer a wide variety of aggregate options and blends thereof in all naturally shaded options.
