SuDS - The Principle

SuDS are physical structures built to receive surface water runoff, normally in the form of infiltration or attenuation solutions. They also provide treatment of surface water by sedimentation, filtration, absorption and bio-degradation. Research shows that up to 80% of sediment; 60% of phosphorous and; 80% of nitrogen can be removed from rainwater through porous paving, together with substantial levels of heavy metals and hydrocarbons.

Design Details - SUDS Associated with porous paving:

Attenuation - Used when direct infiltration is not appropriate and when water storage is required.

This shows Naylor AdPave, infilled with grass or natural ©aggregate, installed on a layer of sand/grit on a Lotrak 100

geotextile separation/filtration layer. Beneath this is a voided sub-base wrapped in an Naylor GM Geomembrane. Collected runoff is discharged via an appropriate Naylor storage device

®(Naylor Aquavoid ) positioned within or below the sub-base and sealed where it exits the geomembrane storage reservoir.

Infiltration - Used whenever possible, subject to appropriate soil conditions and environmental considerations.

Collected runoff is allowed to permeate naturally, through the geotextile separation/filtration layer, into the subgrade eliminating the need for a positive discharge facility.

Naylor AdPave and Naylor HGVGrid are both key products within a sustainable urban drainage system (SuDS). The porous paving allows the efficient attenuation, infiltration and treatment of stormwater runoff at or near its source, inaccordance with current Best Management Practices (BMPs).They are ideal products for grass and gravel reinforcement.The ProductsMade from 100% recycled material, the Naylor AdPave and the Naylor HGVGrid are modular units which work inconjunction with neighbouring units to create an exceptionallydurable, permanently porous, high load bearing structurewhen infilled with either grass or natural aggregate.ApplicationsNaylor AdPave is a general duty system suitable for general use such as car parks, driveways, verges and Park & Ride parks, whereas the Naylor HGVGrid is designed for emergency access routes, coach and lorry parks etc.

AdPave HGVGridApplications

AdPave & HGVGrid Systems

Sustainable Urban Drainage systems (SuDs) are an integral part of the fight against flooding. Porous Paving provides the practicality of allowing both general and heavy vehicles to use surfaces whilst facilitating the free passage of stormwater to infiltrate the ground beneath.

This UK Manufactured clip-together cellular paving system can be gravel-filled or alternatively can be filled with a suitable growing media and seeded to create an aesthetically pleasing grass surface.

AdPave provides a permanent solution for parking or vehicle access routes.

However, it can also be used as a temporary solution on top of existing grassed areas. The system is suitable for both commercial and domestic applications.

AdPave provides a fast and efficient method of upgrading worn concrete or tarmac surfaces without the expensive removal of the existing surface. When filled with decorative gravel the structural 'cells' in the pavers create an attractive and exceptionally hard wearing surface and eliminate the problem of gravel 'migration'. The cells can, alternatively be filled with soil and then seeded to produce a natural grass surface with the strength to handle all kinds of pedestrian and vehicular traffic.

HGVGrid (75mm) Heavy Duty System

Made from 100% recycled plastic, Naylor HGVGrid is very high strength modular system, able to withstand the vigours of regular HGV traffic movements whilst providing an exceptionally durable porous surface. Filled with either grass or gravel it allows for the creation of a SuDs infiltration scheme in the most challenging circumstances. The Naylor HGVGrid sets the standard for heavy duty porous paving; the unique "A" section distributes the load equally and enables units to stack efficiently producing over 25m2 on a standard pallet. The HGVGrid pavers are 600mm x 600mm x 75mm thick (2.78 per m2) and weigh just 10.7kg so are well within the HSE manual handling limits. The unique and innovative male female connection between units prevents uplift – even under extreme loads.

Benefits: Suitable for SLW60 load category; lightweight & easy to install; 100% recycled polymers; flexible and crack resistant; non-toxic and low cell permeability ensures grass remains hydrated; over 95% grass/gravel at surface and the interlock system prevents lifting of units.

Paving Surfaces - Installation

Subgrade: Excavate to formation level, providing a minimal (1:30 - 1:100) fall to the drainage system if non SuDs. Compact the subgrade using either a vibrating roller or plate, making good any soft spots.

Sub-base for Infiltration Surfaces: Install the designed depth of sub-base in 200mm layers (must be free draining for SuDs schemes), compacting each layer (vibratory plate, type DVP

©75/22"). Overlay the sub-base with a Lotrak 100 geotextile (essential to prevent migration), overlapping joints by 200mm.

Bedding Layer: Lay, screed and compact to a 30mm depth of bedding material (5mm grit for HGVGrid, sharp sand for AdPave). For grass reinforcement mix the bedding layer 4:1 with a good quality top soil to ensure good root growth.

Wearing Course: Naylor AdPave & HGVgrid should be laid on a 45 degree laying face locating the locking lugs with adjacent units. Units should be tamped down and the specified root zone or natural aggregate infilled to the top surface to create a permanently porous, high load bearing structure.

For Gravel Fill: Angular (not rounded) aggregate (5-15mm) should be used if adjacent to schools should ideally be 10mm single sized crushed rock.

For Grass Fill: Fill the units with a good quality topsoil to the top and allowed to settle; grass seeding followed by a top dressing with a slow release fertiliser will ensure good grass growth. Water the seeded area regularly and keep traffic of the area for six weeks.

Maintenance: Gravel fill - Occasionally sweep any overfill back into the units - if gravel is sinking check for the presence of geotextile. Grass fill - Once established the area can be trafficked and mown as normal. If infill appears to be sinking top up with loam mix and check for presence of geotextile.

Special Applications Demarcation Blocks

These are available for the Naylor AdPave grid system and are used to delineate parking spaces within car parking areas. Four individual blocks are used to form a simple “T” or alternatively this “T” can be extended to create a series of dotted lines running the length of the parking bay (see photo) requiring eighteen blocks per bay.

Product Data AdPave HGVGrid

Slopes Naylor AdPave grid units can be laid on slopes of up to 15 degrees without additional staking. Where the Naylor AdPave is used on the underside of a bridge abutment (e.g. to comply with the HSE recommended limits) every unit should be staked and the sand bed stabilised with a 12:1 cement mix on the 40 - 45 degree slope.

Disabled Parking Bays: Naylor AdPave is suitable for installation within disabled access areas. A disabled bay sign can easily be created using 130 of the Demarcation Blocks. (data sheet available on request).

HGV Areas: Although the Naylor AdPave system is able to withstand slow moving HGV's (roadside lay-bys etc) for areas subject to regular power assisted turning areas and other areas subject to regular HGV traffic the Naylor HGVGrid should be utilised.

Naylor TechTurf for Fire Access Routes:

TechTurf has been in use for many years for emergency access routes because of its ability to take fire tenders during extreme weather conditions without them getting bogged down or causing excessive rutting.

Recent testing in conjunction with the Fire & Rescue Fighting Unit School in Warsaw saw a series of tests in both dry and saturated conditions involving the repeated manoeuvring and shunting of a fully laden fire tenders and specialist extra heavy ladder units.

Conclusion:

TechTurf met all the requirements of load capacity and deformation of the surface

(rutting > 2 cm in all weathers). This confirmed TechTurf can be used for fire access routes without restriction.

Naylor TechTurf for Multi-use areas:

When historic Chiswick house in West London was looking for additional parking for various major events, they selected Naylor TechTurf as the ideal solution, creating a

23,000m multi use car park suitable for both cars and HGV's.

The result is a free-draining, completely natural grass surface with high load- bearing capabilities, resisting rutting and compaction.

Naylor TechTurf Commercial Use:

The carefully manicured lawns at this Swindon Distribution Centre have a hidden strength that enables their use as a service and emergency access route. The area was created using Naylor TechTurf, allowing multi-use functionality without compromising the aesthetics.

The area provides a sympathetic outlook to the distribution hub whilst also allowing emergency access using a natural structure that resists rutting and compaction, suitable for all types of traffic up to HGV use.

System

The

TechTurfThe TechTurf rootzone reinforcement system was originally developed in the UK following extensive research carried out by the Civil Engineering Department at Strathclyde University and the Turf Grass Science Department at Texas A&M University, USA.

Subsequent research by Strathclyde Uni showed that the use of mesh elements provided up to a 35% improvement in reinforcing effect when compared to all fibre alternatives. The TechTurf system provides a solution to load bearing; trafficked or high wear grassed areas and is SuDs compliant. The system consists of 3 elements:

a) The reinforced rootzone material

b) Specialised fertiliser

c) Specially grown turf to complement the rootzone

The TechTurf rootzone is reinforced with an exact percentage of randomly oriented polypropylene mesh elements. The grass roots penetrate and entwine with the mesh elements, stabilising the system and providing

positive anchorage for the grass plants. The result is an engineered natural grass surface with high load bearing characteristics, improved damage resistance and a unique cultivation property which overcomes the problem of soil compaction. It is an ideal solution for a natural, environment-ally attractive area where excessive traffic loadings are anticipated but a natural grass finish is desired.

The system is therefore ideal for:

Walkways, Emergency access routes, Sport Surfaces, Aviation Areas, Equestrian, Landscaping, Housing Projects & Public Areas

Benefits of Naylor TechTurf:

a) SUDS compliant - Excellent drainage properties.

b) Invisible once installed but still performs.

c) Improved root growth - reinforcement maintains hydration and prevents compaction.

d) Natural Alternative - maintains the natural environment.

e) No grid reinforcement visible.

f) Versatile - Excellent in 'high traffic' areas giving a natural appearance but supplying a hard wearing surface.

g) Ease of Maintenance - No special measures required.

h) Cost Effective - a viable alternative to grid reinforcement.
