New Green-tree roof garden substrates brochure- Now Available

Green-tree, the soil arm of Green-tech, has unveiled their new Green-roof brochure this week.

The brochure comes at a time when the Green-tree team is experiencing unprecedented interest, orders and specifications of its range of roof garden substrates. The substrates are the result of many years of product development with input from Landscape Architects and growing media experts all keen to find a green roof substrate that will present the correct drainage, fertility, organic content and green credentials needed for a complete green roof project.

Green-tree’s range of topsoil’s and growing media is one of the most comprehensive in the industry; including Intensive and Extensive Green Roof substrates, plus the ancilliary products needed to create an ideal growing environment for roof-top plants, shrubs and trees.

The new 12 page brochure has been well received and includes all the essentials for a green roof project, including drainage products, root barriers, wildflowers and green screens. It also highlights a number of projects where green roof substrates have been specified and installed, demonstrating their demand within the UK market.

Green-tree Business Manager, Mark Wood, said.

“The new brochure pulls together our products and experience and provides information for effective green-roofs. As a member of the Green Roof Organisation (GRO) we are supporters of the GRO Code and have developed our products in light of its considerations. The right soil is an essential part of a successful green-roof and the Green-tree soils and growing media tick all the boxes.”

Specified on many major projects nationwide, Green-tree roof garden substrates are renowned for their consistency of quality, availability and green credentials. The most recent high-profile roof garden project involves the Queen Elizabeth Hospital in Gateshead.

Green-tree supplies roof garden products for Queen Elizabeth Hospital, Gateshead

Green-tech has supplied the materials for a roof garden and landscaping at a new state-of-the-art £23m emergency care centre at the Queen Elizabeth Hospital in Gateshead.

The new courtyard roof garden, designed by Southern Green Architects was to provide colour and height with minimal maintenance, all within the load bearing constraints associated with a roof garden.

Grace Landscapes won the contract to provide the landscaping and enlisted the help of landscape suppliers Green-tree to supply their extensive roof garden substrate and gt Roofdrain which are the essential key products of a roof garden. Green-tree also supplied GRB Plus which provides ground protection and stabilisation and basalt chippings which offer a decorative finish.

The new emergency care centre includes accident and emergency facilities, a 36 bed short stay unit, a new main entrance for the hospital and specialist diagnostic equipment.  It proposes to be a one stop shop for the people of Gateshead and the surrounding area. The courtyard roof garden offers a soothing view for the patients and visitors of the emergency care wards.

Green-tech technical advisor Richard Gill comments,

“Green-tree Extensive roof garden substrate is ideal for green roof projects that require little maintenance.  It is lightweight in texture and rich in nutrients which ensure quick plant establishment in harsh rooftop environments.

gt Roofdrain provides an easy-to-install lightweight drainage layer and water reservoir to sustain plant growth. This is ideal for roof gardens where appropriate drainage is essential and the basalt chippings are lightweight and used for decorative purposes within the landscaping scheme.”

Darren Hardman North East Regional Manager from Grace Landscapes endorsed Green-tree, adding

“We’ve worked with Green-tree for a number of years.  Their advice and attention to detail is always appreciated.  They stock a huge range of products and can always deliver quickly.  Their roof garden products were perfect for this job and we were delighted with the results, as is the client.”
