Natural Paving at Auckland Home Show 2014

For those of you we didn’t see at the Home Show in Auckland it was a roaring success. We set up covering the full width of the street of houses and had in excess of 30000 people walking, strolling and rolling over it. The feedback we received was unanimously one of bewildered disbelief. What is usually a medium difficult to navigate at the best of times was supporting wheelchairs, High heels (and some of them were pretty high)! Baby buggies, even pull behind suitcases with no problem at all. Even in what was at times pretty trying weather people were stopping for a chat about where they could use Natural Paving around their home or for their new build. A big thanks to Auckland landscaping and The Ministry of Ground for their efforts with the stand, and everyone who visited the stand for making what could have been very long days enjoyable and entertaining.

Please feel free to upload your project pictures to our website and share your Natural Paving creations.

How do I cut these sheets?

The sheets are very easy to cut. One way which works well is with a box cutter knife with the blade extended. Cut with the geotextile up to reduce shaggy edges if the geotextile is on the far side. Fine tooth saws and power saws are fine too, as are serrated bread knives! They are very easy to cut, the plastic in the matrix is only 1.2mm thick plastic. Each sheet is made of a number of smaller grids welded together. The join double thickness so with a box cutter you have to gnaw the knife a little, but it is quick and simple.

Can i use shells instead of pebbles in Natural Paving?

You can use crushed shell, and you will have the control of any weeds below
the mat, they will not be able to get through the geotextile, but please be
aware that the shell is weak. Under foot traffic it will gradually crush and
compact into the Natural Paving grid in the trafficked area. This will
result in the surface at the top of the grid becoming flat and compact, and
the benefits of the Natural Paving will be compromised.

In contrast, when you use 8 to 14mm pebbles, the stones that overlay the
grid are stabilised because they sit in what are effectively ‘nests’ formed
by the gaps between the pebbles below. Those pebbles are held in place by
the Natural Paving grid. The grid is covered in pebbles and is hidden by the
next two layers of pebbles which is the recommended coverage. The resulting
surface is made up of pebbles all stable because they are nested like eggs
in a crate. The surface looks completely natural but is so stable that even
stiletto heels or the skinny tyres of a racing bicycle traverse it without
displacing the pebbles, and the surface stable.

With shells, you lose all the stabilising influence of shells on top sitting
in ‘nests’ if the shells are crushed underfoot, and compacted into the grid.
If you sprinkle fresh shells on top it would be like sprinkling shells on a
hard flat surface. The time it takes for the shells to crush and compact
depends on the amount of traffic, but, for a while, Natural Paving will
stabilise shells.

If it is the colour you want, then you could consider using white quartz
pebbles which are smooth and nice to walk on, but expensive. You could also
consider using lime chips that are the colour of shells and economical, but
not so nice to walk on..

If you really want the shell finish you could use Natural Paving to hold the
shells in place, but accept that in the longer term maintenance will be
required if the shells become crushed and compacted. This would entail
lifting each mat, tipping out the crushed shells and filling the mats with
fresh shells.

Which edging should I use for my driveway?

Thanks for your fantastic question. Edging is a very important aspect of Natural Paving installation system. The minimum edging we recommend is 100 x 25 rough sawn H4 treated pine for Clutha-garden grade, and 100 x 75 rough sawn H4 treated pine posts for Waiau-Car grade. It is a more substantial lump of wood because cars should be able to run over it without damage. Both these sizes are commonly available and economical. The edging is placed at a level 20mm above the top of the plastic grid. It is there to keep the stones at the edge from rolling off. There should be 15 to 20mm depth of stones covering the grid, not more and not less.

What is the maximum slope I can use Natural Paving?

Thanks for your question.

The maximum recommended slopes for Natural Paving:

CLUTA-Garden grade

Max slope with:
Round pebbles 1 in 5 or 11 Degrees
Crushed gravel 1 in 4 or 14 Degrees

WAIAU-Car grade

Max slope with:
Round pebbles 1 in 6 or 9.5 degrees
Crushed gravel 1 in 5 or 11 degrees

Is Natural Paving a permeable paving surface?

Yes, Natural Paving is a permeable paving surface. It has the permeability and maintainability required to comply with the Auckland Council guidelines. The paved surface, however, is just one of nine elements that contribute to a compliant pavement. On our website you can see a diagram and details of the other eight elements. This is based on the Auckland Council website (click this link to read the pdf version of permeable pavement guidelines specs), The permeable pavement guidelines idea is to intercept runoff and hold it while it infiltrates into the ground, or, its entry into the storm water system is delayed. Where the sub-grade is poor draining soils, in high groundwater areas, or in structurally sensitive soils, the sub-grade is lined with an impermeable membrane and provision is made to collect the infiltrated water and pipe it into the storm water system. Runoff is also intended to be purified of sediment and oil that drips on pavements by the swale action of the base layer. It is also intended that the permeability of the surface can be reinstated if it becomes blocked. Natural Paving filters out sediment so the water entering the reservoir is quite clean. If it is required after a time, Natural Paving can be restored to its original condition by tipping the pebbles out of the mats, washing them and relaying them with clean pebbles. The rain that permeates through the surface needs to be collected and held in a reservoir that has the capacity required by the approving authorities. This reservoir is typically the base course in a permeable pavement. The base course has a strict grading (the distribution of sizes of the stones in the aggregate) to ensure there are air voids after compaction. Air voids weaken base course, so it is needs to be made from tough gravel. The voids are needed to contain the water from the rain. The base course must be from a crushed aggregate to have good shear strength. If the pavement has a clay sub-grade, the council requires an impermeable liner so the clay is not softened by water, and consequently squeeze into the voids. There also needs to be a facility to collect the infiltrated water, and pipe it into the storm water system. The pavement also needs to have strong side support in the ground around the perimeter of the pavement because loads on the surface push sideways within the base course much more than common ‘well graded’ base courses. This requirement is number eight in the specification. Then there is also the environmental considerations of the likely traffic volumes, adjacent land profile and how much run-off it spills onto the pavement, the presence of deciduous trees, the long term maintenance requirements, and the owners acceptance of test and maintenance covenants that the council will apply. I hope you can see that there are many elements that will be considered in the approval of a permeable pavement, and unless they are all present the pavement will not function as intended. Consequently the pavement is assessed as a system for a particular application, and approval of a pavement does not imply another pavement in a different location will also be approved. Natural Paving is an ideal, highly permeable and easily maintainable surface for a permeable pavement. It is a better surface than any other surface because the geotextile bonded to the plastic matrix filters sediment out of the rain, and it is relatively easy to reinstate the original permeability should the surface become clogged. I will be very happy to work with your engineers or landscape professionals to work out the details for the successful application for a permeable pavement.

Natural Paving at Auckland Home Show

We wouldn’t be surprised if you were one of the 12,000 people who walked on Natural Paving pathway in hall 8 at the Auckland Home show. The Natural Paving pathway and pergolas created a natural ambiance to the garden area. The pebbles that you walked on were stabilised by Natural Paving and none of those pebbles shifted, even after 12,000 pairs of feet walked on it over five days.
