Path grade is ideal for patios, paths and gardens around your home and in parks and cycleways in your cities. It enables you to create enduring landscaping features with pebbles.
One very significant feature unique to Natural Paving is that the geotextile keeps the mats locked down under the pebbles, ensuring that the mats are never seen. The geotextile also protects special permeable bases from contamination.
At home, your mower or barbeque will glide across the paving as though it was on a hard surface.
In public areas, it can be used to stabilise pebbles for pathways in parks, gardens and golf courses. Path grade is also suitable for paving paths for cycles or light vehicles, such as mobility scooters and golf carts etc. Cycle-ways made from Path grade are stable, permeable and easy to ride on. It is also good for hard-stand areas for trailers and caravans (if a vehicular base-course is used). It’s ideal for greenhouse floors enabling excess water to drain away, and providing a thermal mass to help regulate heat.

INSTALL THE EDGING
Edging is required all around your paved area. It protects the edge of the Natural Paving mat, retains the pebbles on the mat, and makes a suitable edge so mowers don't fling pebbles. You can use any material for edging, or butt the mat against walls or existing paved areas For pathways, place the edging on the subgrade, but for driveways you lay the base course first.
LAY THE BASE COURSE
Use AP7 to a depth of 65mm then compact or roll it to a compacted depth of 50mm. Screed the surface so it follows the contour you want to achieve for your path or paved area.
Lay a 35 to 40mm layer of bedding material on the compacted base course (on the sub-grade for Path grade). Screed the bedding material to contour the surface close to the finished shape, and compact it. Bedding material is AP7 or bedding sand.
LAY THE NATURAL PAVING MATS
Natural Paving mats are large and easy to lay. They have geotextile welded to the base to anchor it down and prevent weeds growing through it. At two edges of the sheet there is an overlap area in the mat that gives continuity to the weed resistance. There is no clipping together required. The mats can be cut with a hand saw, circular saw, cut off disc. You can easily free form the mats to follow complex shapes.
SPREAD THE PEBBLES
Pour your pebbles or gravel onto the mats and spread with rakes or the like. The pebbles will settle into the mats over time, so fill the mats 20mm deeper than the mat surface and it will settle to a long term thickness of about 10 to 15mm over the top of the mat. This hides the mat so it is invisible, and protects the mat from the sun.
