Ecogrid…a game changer for permeable load bearing parking systems…why?
We are often asked why a client should buy Ecogrid. Other grid examples are mentioned that are, on the surface, cheaper and appear to do the same job. This always appears to be the case, we are all aware of cheap Eastern European or Asian imports in all sectors of manufacturing and most purchasers are well aware that if the product is cheap, it is likely that the product will be of an inferior quality. So let us prove our case.
Apart from the following, let us look at our grids when measured against others and explain the benefits.
DIN 38412 – Neutral for the environment
DIN 4102 – Approval emergency access routes, fire resistance
DIN 1072 – Approval for 20 tonne axle load, driveways, road extensions, bridges
DIN IN ISO 124 and B125 – Approval for car parks, access roads & storage areas
Point axle loading up to 20 T/m², DIN 1072:1985
UV-resistant, certified DIN EN 60068-2-5
Heavy-duty, tried and tested DIN EN 124:2011
Environmentally safe, tested OECD 202:2004
Factory warranty: 20 years from purchase date
NATO certified E50 – MOD / 9330-99-858-1406
We will take the points above on later, for now let’s look at the actual grids:
The benefits of these grids are that they lock firmly together and do not come apart. If grids come apart by hand then they will certainly come apart with light vehicle use then they will lift and break and the surface will become unsafe and unusable, resulting in the lifting of the area and re-installing creating huge end costs. Ecogrid/Ecoraster carries a World patent for its locking system, developed over 21 years of production.
Polyethylene is widely accepted as the best material to manufacture this type of product from, it is highly durable and resistant to all extremes of temperatures and chemicals found in general use. LDPE is the best version of this (Low density polyethylene). This material is suitable flexible for the use with vehicular traffic, in short it bends with use and expands and contracts appropriately with temperature variations. Ecogrid/Ecoraster is made from recycled LDPE.
UV is sunlight, however the agent (carbon black) to provide UV stability is an added material. This costs, if one is looking to sell a product cheaply then there is a temptation not to put it in, ensuring that the product will break down within a very short period of time. Ecogrid/Ecoraster is fully UV stable.
Plastic either as a virgin material (not recycled) or recycled material at the end of the day costs about the same throughout the World and production costs thereof are approximately the same also. Therefore one way to make the product cheaper is to make it lighter, thinner or a mixture of good and bad plastics. If a grid offered is half the weight of Ecogrid, then ask yourself why. Thin walled products will easily break under the weight of even the lightest of vehicles making the surface unusable Ecogrid/Ecoraster E50 is 9.55 KG per square metre and 7mm wall thickness, the heaviest on the market. We don’t make it this heavy for economical production reasons but to produce the best quality product possible.
All ground conditions vary, no matter how you prepare them, they are subject to heave, settlement and many other factors. Grids should be small enough to take on variations in levels, the smaller the better. Larger sized grids (most offered are 500mm x 500mm) ‘bridge’ voids and produce a springy surface, making it far easier for the grids to flex upwards and allow the surface material to ingress under the grids and make the surface once again unsafe and unusable.
Some cheap products are sold with a thin (not to British Standards) membrane pre-attached. A membrane should be placed under the screed layer, a thin membrane attached to a grid will swiftly be punctured easily and quickly making the system useless. A minimum 100g membrane should be used in all or most applications.
Load bearing capacities
A real thorn in our side! Many companies make wild claims about point or spread loading but cannot show where the independent tests were carried out. Anyone can throw a figure in to the mix and hope that the client will be fooled in to thinking them true. Ecogrid is fully and independently tested for its load bearing capacities, said certification can be requested at any time
It is all very well making wild claims about the product but the proof of the pudding is in the eating! Look for case studies pertinent to your use and perhaps visit the installation. We can supply hundreds of case studies from all over the World for hundreds of applications.
So now let’s take accreditations!
TUV certified: This is the European testing organisation similar to the BS standards, they rigorously and independently test products for advertised standards and ensure that they comply.
RAL approved: Due to the flooding of European markets with untested inferior grid products, quality manufacturers joined an organisation that independently tests the warranty of products, mainly they ensure:
1. Grids must a run off¬ factor of less than 0.4 (Ecogrid has a run o¬ rate of 0.2)
2. A warranty greater than legal requirements, minimum 6 years (Ecogrid carries a 20 year warranty)
3. Resistance against acids, salt, leaching, fertilisers and grease (Ecogrid is fully resistant)
4. Expansion at 90 degrees and contraction at minus 16 degrees.(Ecogrid has a maximum expansion/contraction rate of 3%)
5. Ability to withstand crushing according to standards (Ecogrid complies fully pressure test DIN 124, Ball test DIN EN2031-1, impact strength DIN 12064 cat 1-5)
6. Comprehensive installation manuals, easy to handle and install) (Ecogrid has a full range of manuals for installation)
7. Doubtless traceability must be ensured (Ecogrid is from in-house recycled materials, indisputable traceability)
8. Fully UV tested according to DIN 75220, ISO 4892-2(Ecogrid is tested annually)
9. Frost proof and able to withstand snow ploughs and machinery (Ecogrid is fully approved and tested)
10. Has to be made from min 25% recycled plastic and is recyclable (Ecogrid is 100% from recycled plastics and fully recyclable)
They also approve the manufacturing company for ability to supply in quantity, the financial stability of both the manufacturer and supplying agent, stock levels and longevity of supply.
NATO certified: The process involved in being a supplier to either NATO or the MOD is massive. The quality of both product and supply company is put under a microscope! Only the best will do for the army.
CE approved: Another authority approving quality control throughout Europe
Guarantee: Ecogrid is guaranteed for 20 years, having said this, the product has been in use for over 21 years and anyone can visit the first installation which looks as good today as when it was laid.
In short, Ecogrid/Ecoraster is the original product in this field which has been badly copied by all over the years. We sell over 10 million grids Worldwide every year and that figure steadily grows year on year. We provide the surfacing for anything from a domestic driveway to an articulated lorry park, from a countryside pathway to a double decker bus station.
Remember: “The bitterness of poor quality remains long after the sweetness of low price is forgotten”.
