Priora Permeable Block Paving

Priora Permeable Paving, a Sustainable Urban Drainage (SUDS) System for driveways

The unique patented Priora block allows surface water to pass
through into a specially calculated sub base material without
compromising the structural performance of the driveway

The use of SUDS can reduce the risks of flooding and pollution of
the public sewer system especially in times of heavy rainfall

Priora block paving is available in six colours from our popular
Driveline 50 block paving range. Tegula Priora is a more rustic
version available in the three Drivesett Tegula colours

IMPORTANT Installation Note:
The Priora System should not be attempted by the DIY enthusiast
or untrained installer. It requires the careful calculation of a soil
permeability test and appropriate use of specially graded sub-base
aggregates.

Marshalls domestic Priora system must be laid on a sub-grade which has previously had an established and adequate existing driveway and an area which has a sub-grade soil strength greater than 5% and should be laid with a 20mm and 6mm washed, graded, angular aggregate to BSEN12620, to ensure compliance.

Conditions required for Priora
The grade of Priora featured in this brochure is only intended for
normal domestic vehicles and pedestrian traffic, though occasional
delivery vehicles over 3.5tonnes gross weight can be tolerated.

The domestic Priora System is only intended for driveways or paths
where infiltration is required only in the immediate Priora paved
area and not from other surrounding paved or roofed areas (see
rain water catchment area guideline below)

In some parts of the country there are ground conditions where
infiltration could adversely affect foundations to houses, therefore,
if in doubt seek advice from a specialist or the local authority
building control department.

Properties constructed pre 1920 may not have been built on
traditional concrete foundation, therefore, if this is proved to be
correct during excavation then Marshalls Domestic Priora system
should not be installed.

Check for services, Priora must not be installed if gas or electric
services run through intended Priora areas.

Guidelines for Installing Marshalls Priora Permeable Block Paving

Surface Gradient
The intended Priora area must fall away from the owner’s house
and any other buildings in the immediate vicinity.
If the driveway exceeds 20m in length and/or has a gradient
greater than 1 in 100 then please contact Marshalls Technical
Advisory Service.

The top surface of the driveway should finish at least 150mm below
any adjoining wall DPC level.

Existing Foundations
If your house lies adjacent to or less than 600mm from the
proposed Domestic Priora driveway area, establish depth of house
foundation before undertaking any soil test/Priora installation.

The house foundation top surface must be 600mm (minimum) below
the finished level of the top of the proposed Priora driveway.

Soil Strength and Permeability
Marshalls Domestic Priora system must be laid on a subgrade
which has previously had an established and adequate existing
driveway and an area which has a subgrade soil strength greater
than 5%.

The Domestic Priora system is only suitable for soil areas where
infiltration applies and the test criteria have been met as per the
standard permeability test.

For the standard permeability a test hole should be dug for every
20m2 of driveway. There should be a minimum of two holes.
Holes/pits should be spaced evenly in relation to the proposed
Priora area.

Discharge onto Roadway
The Domestic Priora area must not discharge onto surrounding public roadway and pathways and towards any buildings.

Rain Water Catchment Area
No adjoining surface areas (rainwater pipes, roof areas etc) must
drain onto and into the proposed Domestic Priora driveway area,
however, small areas such as door steps and garage areas are
acceptable providing they do not exceed 5% of the driveway area.
Guideline: Catchment area = driveway area
Catchment area = drained surface area

Aggregates
Priora must be laid with 20mm and 6mm washed graded angular
aggregate to BS EN12620 to ensure compliance.

Trees
When installing in close proximity to existing trees, tree roots
smaller than 25mm diameter may be pruned back, preferably to a
side branch, using a suitable pair of secateurs or hand saw.

Roots
larger than 25mm should only be severed following consultation
with an arboriculturist, as they may be essential to the tree’s health
and stability.

Protection of the pavement will also be required, hence the requirement of a permeable root barrier system such as the Geoweb bio barrier system or similar
which is non surface protruding, and therefore, does not present a
trip hazard once installed.

Health and Safety
It is possible that more excavation for a Priora driveway may be
required than that of a driveway constructed of traditional block
paving, therefore, care must be taken when excavating ground to a
deeper level.

Particular care must be taken to protect the sites from
children and partially sighted persons and for collapse of adjoining
features such as boundary walls/fences.

Check for services, Priora must not be installed if gas or electric
services run through intended Priora areas.

Care must be taken when constructing over Sewer, rainwater pipes
and water pipes to ensure that the services remain supported for
their full length by undisturbed material and are surrounded on
the remaining sides by a minimum of 150mm of 6mm material to
protect the service.
