Aggregate – Gravel
Loose gravel provides a simple surfacing solution. Correct preparation is vital to prevent it sinking, migrating and forming ruts. Edging, landscape fabric and interlocking cellular paving panels are required to stabilize the surface. The entire system is SUDS compliant. Over time the surface will become susceptible to weed growth on build-up of dust and detritus. This can be combatted using weed killer sprayed onto the affected area. To combat the stones crumbling through heavy vehicular use, we would recommend angular flint chippings.
Block paving offers a variety of patterns and colours. Once installed, the surface is permeable and SUDS compliant, with any surface water filtering through the sand joints to the sub-layer. Any damaged stones can be replaced individually with minimal change in appearance. As with gravel, weed killer may be required to combat plant growth in the joints. We have installed block paving, flagstones, granite setts and natural stone on numerous projects over the years and can attest that it makes for an attractive, durable surface.
CCE are fully geared to provide this most widely used surface. Aggregate mixed with tar can be used anywhere is suited to areas of heavy traffic and can be laid over large areas.
It is flexible, and does not need to have expansion or contraction joints within the surface
Care is needed to lay at an adequate depth and of a suitable ‘grade’ for the intended traffic.
Asphalt is our preferred sub layer to our range of resin bound and bonded surfaces.
Tar Spray & Chip
Rough in texture, with a vast array of aggregate colours, this is a cheaper alternative to our resin bonded system. Hot bitumen is sprayed over the prepared surface. 6-10mm aggregate chippings are scattered then rolled over to ensure full bonding. This system is not as hard-wearing as our bonded system and can wear grooves with regular traffic. In the heat, the bitumen loses structure and black can show through in areas of heavy use. This method is non-permeable so additional drainage would be required.
Using CCE-Surfacing’s proven resin bound aggregates to surround growing trees in places including supermarket car parks, urban areas and high profile housing developments is becoming the new standard.
It is fully permeable, complying with SUDS legislation, allows necessary air & water penetration, and in turn helps growing trees to flourish.
Our system is durable and atractive, allowing for easy cleaning by mechanical sweepers.
When used to surround trees in an area where they will be subjected to heavy footfall or vehicular use, the addition of a honeycomb cell matrix to provide extra rigidity and support for the tree may be recommended.
Following recent legislation, Sustainable Urban Drainage Systems (SUDS) is close to becoming mandatory and permeable paving the norm for all hard-surfacing requirements. ‘SUDS’ Standards
CCE Surfacing Resin Bound Surface is ideal for a large range of landscaping projects, and is suitable for driveways, courtyards, pathways, commercial premises, housing developments, etc.
The Resin Bound system prevents flash flooding, by holding the water in the voids around the stone, until the water can be absorbed into the ground. This method also reduces the risk of standing water. As this system is porous, water is able to freeze and contract without causing damage.
Traditional drainage is designed to remove floodwater as quickly as possible, to either watercourses or soakaways. This water is referred to as “run off”. This run off will contain pollutants arising from several different sources. In urban areas it is very likely to contain organic matter, as well as silt, oil/petrol derivatives.
Progressive urban development has resulted in an increase of run off to watercourses after heavy rainfall. Because rainfall can travel quickly to the watercourses via impermeable surfaces there is very little natural filtration to reduce levels of pollutants. In recent years there has been a significant increase of fast surface run off, causing major flooding. This is mainly caused by the immediate run off from hard paved areas rather than the much slower route through grassed areas, topsoil etc.
Permeable paving allows water to pass through the surface. Pollutants are trapped below the surface where many are broken down by natural processes. This also prevents water pooling on impermeable surfaces which can cause puddles and, in winter months, ice.
Planning permission will not be required if a new or replacement driveway
of any size using permeable/porous surfacing (resin bound surfacing,) permeable concrete, block paving, loose gravel, or porous asphalt, or if rainwater is directed to a lawn or border and allowed to drain naturally.
Planning permission is required for any surface of more than 5 square meters if using traditional impermeable surfaces.
CCE Surfacing can offer resin bound systems that are compliant with “SUDS” (Sustainable Urban Drainage Systems). The resin bound systems are both permeable and porous, dependent on application and use. The type of substrate will also have an impact on which type will work best. We are always happy to advise on the base build-up of your project.
Sustainable drainage is a departure from the traditional approach to draining sites.
There are some key principles that influence the planning and design process enabling them to mimic natural drainage by:
- storing runoff and releasing it slowly (attenuation)
- allowing water to soak into the ground (infiltration)
- Slowly transporting (conveying) water on the surface
- filtering out pollutants
- allowing sediments to settle out by controlling the flow of the water
A resin bound rubber crumb surface is a blended mix of rubber granules bound together with a single part polyurethane resin, having been mixed on site in a specialist mixer and laid on an existing suitable; or specially prepared base, to provide a virtually continuous surfacing. It is most commonly installed as a two-layer system with the wearing course, always normally being a nominal depth of 15mm, with the ‘shock pad’ base depth being variable to meet with the CFH requirements of any play equipment
Our resin bound rubber crumb surfacing is tested to comply with BS : EN 1177 : 1998
The wearing course / layer is constructed from a 1-4mm EPDM (Ethylene Propylene Diene Monomer) rubber.
Rubber Crumb surfaces are manufactured using recycled tyres and thus are very environmentally friendly.
It is available in a wide variety of colours and patterns and can be applied to almost any area to make a seamless, smooth, and porous surface.
Rubber crumb is the ideal surface product for any area where there is a risk of falling, particularly when used by young children or the elderly.
The finished surface is highly resistant to rust, oil, corrosion, salt or cracking due to changes in temperature.
CCE Surfacing’s Rubber Crumb sub-base & Resin Bound Rubber Surface is ideal for a large range of landscaping projects, and is suitable for driveways, courtyards, pathways, commercial premises, housing developments, etc.
This system prevents flash flooding, by holding the water in the voids around the rubber, until the water can be absorbed into the ground. This method also reduces the risk of standing water. As this system is porous, water is able to freeze and contract without causing damage.
Using this system, can give a landscaping project several BREEAM credits.
