RonaDeck Tree Pit protects life enhancing Hackney trees

RonaDeck Tree Pit Surround

Tree Pit

London is and always has been a tree lined city. Some of the benefits are obvious, trees are beautiful to look at – marking the seasons with blossom, seeds and changing leaf colours, they provide homes to a variety of wildlife and on a more practical level create shade and shelter.

Trees have invisible benefits too; absorbing carbon dioxide from the atmosphere as part of the photosynthesis process which allows them to grow. This removal of CO2 from the atmosphere trees can reduce the effects of pollution by cleaning the air and reducing temperatures. Large leaf canopies catch rainfall and slow down the water’s progress from sky to the ground, helping to reduce flash flooding.

Trees also release oxygen into the atmosphere and their leaves catch dust and pollutants in the air preventing them from spreading further, they reduce smog formation, radiant energy from the sun is absorbed or deflected by leaves, this combination of factors reduces the incidence of asthma, skin cancer and stress-related illness.

Trees can even reduce crime! The presence of trees creates a more pleasant environment that people want to go out and enjoy. Simply having more people around to potentially discover and report crime and this deters criminal activity.

Many London Boroughs have embraced the need to preserve existing trees, replace diseased and dead trees and plant new trees, but planting and maintaining trees in an urban environment is not without problems.

A tree’s root system obviously needs access to water in order for the tree to survive, the roots also need to be able to move as they grow. However a natural earth setting is not possible in a pedestrianised street as it can get very muddy, slippery and be hard to keep leaf and litter free and trees are at risk of root damage or being uprooted entirely. Traditional tree grilles provide irrigation and protection for the tree roots but they are difficult to keep clean as litter, dog waste, cigarette stubs and even hypodermic needles get deposited or trapped between the bars.

The London Borough of Hackney asked Civil Engineering Contractor Volker Fitzpatrick to solve the problem of protecting the roots of the many trees which enhance the streets of Hackney, situated on the doorstep of the Olympic site.

 RonaDeck Tree Pit System from Ronacrete was recommended for its SuDS compliance, ease of maintenance, flexibility and for the appearance of the resin bound gravel.

RonaDeck Tree Pit System is a natural aggregate finish surround for planted trees in public and private areas. RonaDeck Tree Pit System surrounds the tree in a solid yet flexible construction that is easily swept clean and has a porous structure that allows rainwater to seep immediately through to the root system and reduces the burden on surface water drainage.

Sub contractor AJ O’Connor purchased the RonaDeck Tree Pit System through specialist construction industry distributor WT Burdens and gradually the system has been applied over a large area.

AJ O’Connor excavated around each tree to a depth of 150-200mm and filled the excavation with gravel to within 50 mm – 75 mm of the surface, the required depth of RonaDeck Tree Pit System, depending on expected traffic. The two-part resin was mixed with a drill and paddle before being added to the kiln-dried aggregate component in a high capacity forced action mixer. The mixture was then laid on the prepared gravel base and levelled off; allowing a curing time of four hours for foot traffic and one day for vehicles.

 

National Museum for Wales

Resin bonded surfacing at the National Museum for Wales

Ronadeck Resin Bonded Surfacing has been laid onto external pathways and communal areas within the landscaped gardens and grounds of the National Waterfront Museum in Swansea. The museum, which opened in the summer of 2005, tells the story ofWales’ industrial and maritime heritage.

The building and landscaping was designed by Wilkinson Eyre Architects, and features over 7,000 m2 of interconnecting external pathways. The pathways needed to be slip resistant in all weathers with an attractive surface that complemented the overall design. Ronadeck Resin Bonded Surfacing is a hardwearing, natural surfacing system that offers excellent slip-resistance. It is also strong enough to take the museum’s regular vehicular service traffic. Ronadeck Resin Bonded Surfacing Winter Grade can also be applied in cold, damp conditions, an advantage on this project which was completed during the wet winter months.

Ronadeck Resin Bonded Scratch Coat was applied to regulate the surface of the substrate, before application of Ronadeck Resin Bonded Surfacing Buff Resin. Chinese Bauxite aggregate was immediately cast into the rapid curing resin, to ensure full penetration into the resin and left to cure for two hours. After being swept, the paths were ready for immediate use.

Ronadeck Resin Bonded Surfacing is a slip-resistant, durable, fast curing surfacing available in a variety of colours. It has been successfully used for a wide variety of paving applications including the walkways from car park to the terminal atStanstedAirport, highways, concourses, footbridges, pathways, driveways, car parks, balconies and terraces, boardwalks, jetties, ramps and steps.  The ideal substrate for Ronadeck Resin Bonded Surfacing is concrete but flexible pavement is frequently treated.  Hardwood and steel, mostly for boardwalks, jetties and footbridges have also been successfully made slip resistant with Ronadeck Resin Bonded Surfacing.

6 Nations Rugby fans to walk on RonaDeck Resin Bound Surfacing

‘Twickers’ gives it a try

Twickenham Stadium, the largest rugby union stadium in the United Kingdom, was recently enlarged to seat 82,000 making it the second largest UKstadium, second only to Wembley.
 
‘Twickers’ is home to Rugby Football Union and therefore a primary venue for rugby union including the 6 Nations Championship. The stadium is considered an icon of English rugby and hosts other major concert events such as The Rolling Stones, Genesis, U2 and Eagles.
 
Recently the tarmac paving outside the stadium was renewed and paths and walkways were applied on top of the new tarmac.
 
Ronacrete’s RonaDeck Resin Bound Surfacing System was applied at a thickness of 15mm by contractors F M Conway Ltd to create decorative, slip-resistant pavements for the sports, music and other fans who use the stadium’s facilities every week.

RonaDeck Resin Bound Surfacing System was supplied in easy to use packaging comprising a two-component polyurethane resin together with aggregates for easy on-site mixing in a forced action mixer. The two component non-yellowing resin was mixed with a drill and paddle mixer and added to the dry aggregate, mixed and then laid onto the prepared surface.

Four hours until footsteps

Within just four hours the new surface was ready for the feet of the famous and of their many fans. 

Importantly it satisfies the SuDS regulations allowing rainwater to quickly and easily drain through the permeable surface, is slip resistant and is quick and easy to lay.

Walkway for Westfield

Resin bound surfacing at Westfield Shopping City

RonaDeck Resin Bound Surfacing in London

Westfield Stratford City retail and leisure development situated in Stratford in East London is not only the largest urban shopping centre in Europe but is also the most environmentally friendly shopping complex in Britain. Built at a cost of £1.8billion, it contains 1.9 million square feet of retail and leisure space. Westfield Stratford City is located adjacent to the Olympic Park and will form the prestigious gateway to the Olympic Games in 2012.
There are 250 shops and over 70 places to eat and drink in the complex which includes a 17- screen, all-digital Vue cinema; 14 lane, All Star Lanes bowling and the UK’s largest casino. A pedestrianised street runs through the development, linking John Lewis at one end with Marks & Spencer at the other.

Specialist contractors Cemplas were employed to lay the surfacing element of the hard landscaping package, a key feature in the complex that covers over 3000m2. The surfacing system used was RonaDeck Resin Bound Surfacing, a permeable paving system consisting of blended aggregates bound in a UV resistant elastic resin. RonaDeck Resin Bound Surfacing provides an attractive porous pavement for pedestrians and light vehicle traffic. The inbuilt porosity prevents surface ponding of rainwater and allows water to drain naturally, feeding plants, natural watercourses or manmade drainage systems. The system is SUDs* compliant, in keeping with the environmental aims of Westfield. The elasticity of the resin means that there is a ‘give’ to the surface, this makes it more comfortable to walk on and provides resilience to localised pressure which could cause damage to surfacings with more brittle binders.

Golden Harvest aggregate was selected for the walkway from Ronacrete’s range of natural aggregates, each formulated for strength and appearance. The ultra violet stability of the resin ensures that as the surfacing ages, the appearance of the aggregates will not be spoilt by the discolouration that is characteristic of cheaper resin systems.

Cemplas applied the RonaDeck Resin Bound Surfacing system to an asphalt substrate which was laid to form a firm base. The RonaDeck Resin Bound Surfacing system is supplied as a two component polyurethane resin together with a blend of kiln-dried aggregates for on-site mixing in a forced action mixer. Cemplas first mixed the two component resin with a drill and paddle before adding the mixed resin to Golden Harvest aggregate in the high capacity forced action mixer. As soon as the aggregate was fully coated with resin, the mixed material was discharged from the mixer and trowel applied at a thickness of 18mm onto the prepared asphalt surface. The finished system was ready for foot traffic within four hours of being laid.
