StablePAVE HD

Fully interlocking heavy duty gravel grid

Stable

PAVE HD

WHAT IS IT?

StablePAVE HD is a purpose designed, fully

interlocking honeycomb structure for the

stabilisation, containment and reinforcement

of natural gravel surfaces. It is the most

robust of the StablePAVE product group

and can be used in all light vehicular and

pedestrian applications, including constant

access commercial or municipal car parking.

StablePAVE HD is produced in panels of

1.200 x 0.800 mtr x 38 mm deep. (0.96 sq.

mtr), complete with a double strength weed

suppressant membrane attached to the

base. The robust interlocking mechanism

gives exceptional stability with lateral load

resistance, especially beneficial where

heavier traffic applications are anticipated.

LOW CARBON FOOTPRINT

(Breeam compatibility):

StablePAVE HD is light grey in colour offering

minimal visual impact and is manufactured

from specially selected, premium quality virgin

and re-cycled raw material. The product can

be fully re-cycled in itself, which leads to an

ultra-low carbon footprint in production, use

and disposal.

When used with traditional local, natural

aggregates, the StablePAVE HD system

offers a significant contribution to beneficial

BREEAM ratings in the landscaping and

external works around your building. The

contribution can be further enhanced by

the utilisation of re-cycled decorative

aggregates.

WHAT DOES IT DO?

StablePAVE HD provides a free draining

permeable paving layer. The reinforcing

structure prevents rutting, restricts gravel

migration and can withstand a compressive

loading of over 280 tonnes/sq. mtr. The

design criteria is to accommodate heavier

vehicles up to and including emergency and

utility access.

Addition lateral load resistance from the

interlocking design makes StablePAVE HD

particularly suitable for heavy small wheeled

maintenance or utility plant, horse boxes

and other high point loading wheeled

vehicles.

SUDS (Sustainable Drainage):

Even with a traditional compacted sub base

the system creates a free draining,

permeable paving layer which virtually

eliminates surface water run-off. This

substantially reduces demand on surface

water drainage capacity.

StablePAVE HD is eminently suitable for

use in conjunction with fully permeable sub

base construction and over water harvesting

installations.

PRODUCTIVITY:

The system is fast and easy to install, which is a major cost consideration, when compared to the alternatives.

Installation rates of up to 250 sq. metres per day with a single small crew are achievable, making StablePAVE HD

a very economical paving selection.

grid for pedestrian only applications.

Coloured black* with a double strength

weed suppressant membrane attached to

the base, StablePATH ECO offers an ideal

combination of permeable performance,

economy and productivity. The panel is

produced in a light weight, user friendly

size of 1.200 x 0.800 mtr x 30 mm deep,

which is very easily cut to shape.

Panels have interconnecting location pins,

which aid accuracy and speed of installation.

Applications are primarily pedestrian,

although the grids are strong enough to

withstand regular traffic use from landscape

and maintenance equipment.



StablePATH ECO is manufactured from

100% re-cycled raw material. The panels

themselves and any off cuts can be fully

recycled, which leads to an ultra-low carbon

footprint in manufacture, use and disposal.

StablePATH lends itself to utilising locally

sourced or re-cycled aggregates, further

enhancing the products environmental

credentials. Low gravel demand of

55kg – 65 kg per sq. metre utilises much

less material than unreinforced gravel

options or bound surfaces.

WHAT DOES IT DO?

StablePATH ECO provides a truly permeable

reinforcement for gravels and pathway fills,

which offers a natural alternative to resin

bonded surfaces, asphalt, concrete or pavers.

The honeycomb structure reinforces the

aggregate layer, which prevents rutting,

spreading and migration of the chippings.

Suitable for all pedestrian uses, such as

paths, patios, roof gardens, quadrangles and

leisure areas, StablePATH ECO creates a

solid, permeable, wheelchair and bicycle

friendly surface.

Very competitively priced, without

compromise on durability, StablePATH ECO

is tested to the same standards as the other

reinforcing grids in the StablePAVE range.

It is fast and easy to install, making this the

ideal solution where budget considerations

are paramount.


Planning requirements for hard paved

surfaces to have minimum impact on

surface drainage capacity necessitates

formal planning approval in most parts of

the UK. StablePATH ECO addresses those

issues entirely, so does not need such

approvals.

The system can be used as part of a fully

permeable sub base construction or water

harvesting applications.

*Also available in translucent white, at extra cost.

PRODUCTIVITY:

StablePATH ECO is fast and easy to install, so whether the application is large or small the client can be sure

that construction time will be minimised, thereby ensuring a cost effective outcome. The combination of

competitive product cost and fast rates of installation make StablePATH ECO a wise and budget conscious

choice for designers, installers and clients.

suppressant membrane attached to the

base. Designed for residential landscapers

and paving contractors, the panel is

produced in a user friendly size of 1.200 mtr

x 0.800 mtr by 30mm or 40mm deep, which

is very easily cut to shape.

It is fully tested for compressive loadings of

130 tonnes per sq. mtr (63kN) when empty

and 400 tonnes per sq. mtr (193kN) when

filled with gravel. UV resistance is

incorporated into the formulation at

industry leading levels.



StablePAVE TRADE is manufactured from

specially selected, premium quality virgin

and re-cycled raw material. Products can be

fully re-cycled themselves, which leads to an

ultra-low carbon footprint in manufacture, use

and disposal.

The system lends itself to utilising locally

sourced or re-cycled aggregates (where

appropriate) so carbon miles can be

minimised. Even where imported aggregates

are preferred, the low gravel demand of

65 – 75 kg per sq. metre utilises much less

material than unreinforced gravel options or

bound surfaces.

WHAT DOES IT DO?

StablePAVE TRADE provides a free draining,

permeable paving layer for residential

driveways, paths and patios. The honeycomb

prevents rutting, spreading and gravel

migration. Additionally the honeycomb

structure reinforces the gravel layer to give

paving layer strength comparable to concrete

or asphalt. The panels have a connector pin

to facilitate secure location of the panels

which assists fast and accurate placement.

The finished surface is suitable for vehicle,

pedestrian and wheelchair use. StablePAVE

TRADE is an economical paving choice for

residential applications combining durability,

unlimited choice of aggregate finish,

permeability and fast installation.

Very competitively priced, without

compromise on durability, StablePAVE

TRADE is tested to the same standards as

the other reinforcing grids in the StablePAVE

range. It is fast and easy to install, making

this the ideal solution where budget

considerations are paramount.


Planning demands for hard surfaces to have

minimum impact on surface drainage

capacity is now a specific requirement in

most parts of the UK. StablePAVE TRADE

addresses those issues entirely, so does not

require planning approval in Sustainable

Drainage terms.

The system can be used as part of a fully

permeable sub base construction or water

harvesting installations.

PRODUCTIVITY:

Stabilised Gravel Honeycomb Grids are fast and easy to install, which is a major cost consideration when

compared to the alternatives. Installation rates of up to 250 sq. metres per day with a single small crew are

achievable, making StablePAVE TRADE a very economical paving choice.

StableGRASS MAXI

Large panel, fully interlocking grass paver

Stable

GRASS MAXI

WHAT IS IT?

StableGRASS MAXI is a uniquely large grass

grid for the reinforcement and containment

of grass surfaces, to facilitate regular use

and access by both vehicular and

pedestrian traffic.

The fully interlocking panels are

1.200 x 0.800 mtr x 38mm deep. This

allows for installation in a brick bond

pattern which, combined with the reduction

in joints,adds substantial stability to the

construction and performance. In addition

the larger units facilitate significantly faster

placement.

StableGRASS MAXI panels are tested to

resist minimum compression loadings of

65Kn per square metre, with greater loading

capacity achievable depending on the sub

strata used.

The design and strong construction of the

cells allows for superior provision of root

development space with minimal restriction.



StableGRASS is manufactured from 100%

re-cycled HDPE and is UV treated. The

product can be fully re-cycled in itself which

leads to an ultra-low carbon footprint in

manufacture, use and disposal.

As a permeable paving which facilitates

vegetation growth the end result is

environmentally beneficial whilst enabling

land use for pedestrians and vehicles.

WHAT DOES IT DO?

StableGRASS provides reinforcement for

seeded grass, turf, green roofs or sedum

surfaces to allow regular pedestrian access

and vehicle use in a variety of applications.

Depending on sub base provision these can

include car parking, vehicle, plant and

equipment access, access roads in

environmentally sensitive areas, communal

social spaces and woodland pathways.

The system can be used both as

containment of growing vegetation or as

reinforcement under turf, and is naturally

permeable.


The system can replace hard surface paving,

which would require planning permission

application for approval in Sustainable

Drainage terms. As a permeable surface, use

of StableGRASS will eliminate water run-off,

presenting minimal impact on demand for

surface water drainage capacity.

StableGRASS can be used in conjunction

with full permeable sub-base construction

or water harvesting installations.

*Two heavier duty grades in black are

available on special order: 50mm deep

StableGRASS PRO and 70mm deep

StableGRASS HD.

PRODUCTIVITY:

A key benefit with StableGRASS MAXI is that the large panels allow exceptionally fast rates on placement. This

translates to making selection of StableGRASS MAXI even more cost effective.

Sub Base GUIDELINES

Stablised gravel paving

Stabilised gravel honeycomb elements should be placed on suitable, compacted previously constructed sub

base (see below for sub base options)

Sub base should receive a lightly compacted blinding layer of up to 25-30 mm of grit sand or limestone/

granite fines.

Units should be bedded onto blinded surface, in a flat layer, to a slight fall if required.

Stabilised gravel honeycombs units are then overfilled with selected gravel to a recommended depth.

Gravel requirement will be 65 kg and 75kg per sq.metre depending on system used.

After fill, surface should receive a misting of water to wash through any residual surface fines and then

accelerate consolidation by a single pass with a plate vibrator or similar light compaction aid

NOTES - FOR SUB BASE OPTIONS

a. For most applications including pedestrian, light vehicle and occasional access by emergency and utility

traffic, sub base should comprises of 10 cm of fully compacted type 1 sub base, with a 25-30mm binding layer.

b. For regular heavier vehicle access and heavy traffic areas, such as car parks.15cm of fully compacted type 1

sub base, with a 25-30mm blinding layer

c. For domestic, pedestrian only applications it is possible to set the units onto compacted earth, followed by

a sand binding layer.

d. For fully permeable paving, or water harvesting applications make

up should be:

i. Earth fully compacted

ii. Layer of geotextile

iii. 25 -27.5 cm of single size filter media gravel, compacted in layers.

iv Geotextile layer

v. Sand/fines bedding layer

vi. Stabilised gravel honeycombs panels filled to required depth and finished as per recommendations above.

StableEDGE

Simply flexible aluminium edge restraint

Stable

EDGE

The StableEDGE paver restraint system is an “L” shaped flexible aluminium section in 2.400 mtr lengths.

Connectors and 250mm spiral steel stakes are included.

StableEDGE is equally suitable for straight lengths or curved shapes. The section is reversible and can be set

underneath the paving or as a buttress outside the paving layer. A range of sizes is offered related to traditional

depths of paving elements (see table below).

FLEXIBLE: Robust construction ensures line

can be precise on straight lengths. Notched

base allows the edgings to accommodate

smooth curves where they are a requirement.

RECESSED or UPSTAND: The restraints

are equally effective recessed below the

finished paving level or set as an upstand

at perimeters to retain other landscape

elements such as lawns or flower beds.

( See table below for depth options).

SECURE CONNECTION: Simple splicing

system securely connects each length to

the next, without obstructing vertical face

support to the paving, in either direction.

INSTALLATION: StableEDGE should be

pinned through a flat, suitable compacted

sub-base, using the 250mm spiral steel

stakes provided. It is generally recommended

that the edge restraints should be staked

below the bedding sand layer, as sharp sand

can wash out over time. Fix edge restraints

to one side of the installation with the base

underneath the paving edge, as a guideline.

Lay pavers from the edge restraint outwards

to the required distance then fix parallel

restraint as a buttress with the base facing

away from the paving. Recessed restraints

should be approx.. 10mm below the paving

surface. Upstands depth determined by site

requirements.

DURABLE: Manufacture in high strength

aluminium with added stability from the

section profile, ensures long term durability.

StableEDGE will not rot like wood, rust like

steel or crack like many plastics.

STAKING DISTANCES:

For entry way, walk ways, patios etc. stake every 50 – 70 cm.

For cart paths, running tracks and driveways stake every 40 – 60 cm.

For heavier vehicle applications and asphalt edges, stake every 30 - 40cm.
