Hi-tech fix for erosion and boggy ground
MARTYN Hammacher reckons the only people with dry feet at this year’s Primex event in Casino were the ones manning his exhibit.
That’s because they were standing on the product he was there to promote – Geohex, a recycled plastic paver that halts erosion and stabilises the ground.
It allowed water to drain away more quickly – something that was even more welcome at the recent sub-zero Mudgee Small Farm Field Days.
Farmers’ response to the product was 100% positive, said Martyn, whose MH Agency is the North Coast’s authorised supplier of Geohex, which is made in Minto.
The sight of a cattle trough encircled by the product and a dry sand covering at Martyn’s stand drew the attention of landowners desperate for a long-term solution to the year-after-year damage to their roads and property following heavy rain.
Geohex can be used in any situation where there is erosion or problems with mud and bog, including at watering sites, roads, stockyards, nurseries, equestrian centres, walking arenas, parking spots, drives and gateways, Martyn said.
“It came out in May last year and is the latest technology in erosion control and ground stabilisation.
“It’s a paver and can be used anywhere – including on slopes and down into depressions, because although it’s rigid, it has an interlocking system.”
It can also be cut to shape. When Martyn moved to the North Coast from Germany nine years ago, he lived on a cattle farm and noticed that most properties in the region had problems with boggy conditions, water run-off and erosion damage.
Searching for a solution he discovered the product made by A Plus Plastics.
“It ticked all the boxes,” he said, including meeting his “green” requirements.
“I don’t like plastics, but the Geohex paver is made from 100% recycled plastics into polypropylene, and that makes it strong, which is perfect to stabilise the ground and the substrate.”
Laying it is a DIY job, beginning with grading off pot holes and corrugated sections, then, depending on the job, putting down layers of road base followed by crusher dust.
“You lay the Geohex in that bed and compact it. After that you can fill it with whatever you like, road base, granite or even just crusher dust, pumice or blue metal. Then you have to compact it again and it will stabilise the ground.”
Because it’s almost 100% water permeable, the water naturally runs away, both off the surface and through the drainage inside the pavers.
It can bear a load of 1000 tonne per square metre. And at $29sq m – or less for volume – it’s highly cost-effective.
“For stock it’s a very healthy solution,” says Martyn, “and especially good to stabilise ground around water troughs where it always gets muddy.”
It comes in black, though mines use the coloured varieties to delineate underground roads.
For the domestic user, on driveways, for instance, it can be filled with pebbles, or seeded or grassed over.
