TCS ATTENDED THE LANDSCAPE SHOW

The 17th and 18th September 2019 brought the annual Landscape Show to the beautiful setting of Battersea Park in Central London. Set within the park itself in the Evolution Centre, the show was held over two days with exhibitors and visitors from a range of disciplines including geotechnical suppliers and manufacturers, landscape and garden designers and architects and landscape contractors.

TCS Geotechnics were exhibiting our wide range of geosynthetic products including Tensar Geogrids, Woven and Non-Woven Geotextiles a comprehensive range of Techline Geomembranes and preformed ‘shoebox’ liners and the full range of geosynthetic Formpave Aquaflow Components.

Perhaps most relevant to the Landscape Show audience was our range of Techcell Geocellular confinement systems providing solutions for Tree Root Protection, soil erosion and stabilisation, our standard and bespoke range of Gabion Baskets and our specialist range of stock Dupont’s Premium  root and weed barriers.

ROOT & WEED BARRIERS

Gary Norris, the UK Sales Manager for Dupont, joined us on the stand to jointly promote the use of DuPont™ Plantex® for tackling problems such as Japanese Knotweed and other invasive plant species.

DuPont™ Plantex® Platinium with its performance enhanced intrinsic strength, is resistant to the most aggressive weeds. Whether its Japanese knotweed, couch grass, reed, giant reed, giant hogweed, marestail, horsetail, bamboo or Himalayan balsam, Plantex® Platinium will deliver the resistance required.  Following numerous test by DuPont’s R&D team over several years in natural environments, no perforation or regrowth through the fabric has been observed. Once correctly installed on an area contaminated by invasive plants it does not require periodic maintenance, unlike alternative solutions like periodic chemical treatment or physical removal.

Platinium is available in widths of 2.5m and 5m. The 5m width is especially important when covering large areas as it requires fewer joints. The material is simply rolled out and covered and, if required, jointing can be undertaken relatively simply by taping or welding.

DuPont™ Plantex® Gold is an aesthetically appealing bi-coloured, non-woven Polypropylene weed control barrier for long lasting, highly effective and chemical-free weed control and is ideal for application on slopes where it can be used covered as well as uncovered.

DuPont™ Plantex® RootBarrier is a coated non-woven impermeable membrane, ideal for underground piping and cable systems protection.

DuPont™ Plantex® RootProtector is an air and water permeable non-woven root barrier, making it ideal for horizontal installations such as cycle tracks, green roofs, paths, roadways and drives.

TREE ROOT PROTECTION

An increase in urbanisation combined with the need to preserve flora has led to a rise in development in areas where the continued health of mature trees must be assured within the close vicinity of buildings and associated infrastructure. The preservation of these trees is generally ensured via Tree Preservation Orders (TPOs).

Of particular note is the fact that cutting or otherwise damaging roots via excavation around them is also a restricted activity under TPOs.  However actual cutting of the tree roots is not required for the tree to suffer the ill effects of construction.  As many tree roots are found within the first metre of soil, trees see a decline in health when the areas surrounding the trees are not protected from trafficking by vehicles and plant. The trafficking not only crushes the roots but also compacts the soil around and above them reducing the permeability to water, air and also restricting the activity of burrowing insects and other fauna, which normally maintain a nutrient-rich healthy soil structure.

So-called ‘no dig’ solutions are sought which provide a stabilised raft or stiffened layer above the root zone capable of spreading the load of trafficking vehicles and inhibiting the effects on the soil and roots below.  TCS’s Techcell cellular confinement system offers such a solution. When filled with a 4mm – 20mm or 20mm – 40mm clean angular gravel, Techcell creates a permeable stable surface which distributes the loads imposed by vehicular traffic whilst allowing water, air, and nutrients to reach the tree roots preserving the health of the tree.

The British Standards Institute BS 5837:2012 provides recommendations relating to tree care, with a view to achieving a harmonious and sustainable relationship between new construction/existing structures and their surrounding trees. Techcell not only complies with BS 5837:2012 but also with Arboriculture practice note 12 (APN12).

GABION BASKETS

TCS Geotechnics offer a range of wire mesh gabion baskets that are delivered flat packed and ready to be assembled via wire or helical fixings and filled on site. Gabion baskets can be filled with rounded stone, angular rock or recycled materials like crushed concrete as required.

Gabions are typically supplied in 76.2mm x 76.2mm aperture welded mesh (other mesh sizes available) and provided in Zinc coated triple life corrosion protection as standard, optional PVC coating or stainless steel wire are also available.

TCS Gabions are typically used to create free draining gravity retaining structures in slope stabilisation and erosion protection applications. The infilled gabions can be used to secure erosive landscapes and provide structural support for applications such as bridge abutments, wing walls and outlet aprons, TCS gabions can also be used to clad unsightly areas to improve aesthetics.

As indicated above, units can also be manufactured from other non-standard mesh sizes or combinations of wire diameters to suit particular needs and stainless steel gabions are also available to special order.

VERSA STREET FURNITURE

TCS also shared our stand with our sister company Versa street furniture.

Versa specialise in the design, manufacture, and installation of quality street furniture, canopies & shelters.

The street furniture Versa can supply include bollards, access control and barriers, cycle stands, seating, litter bins, planters, tree protection, post & rail systems, signage and boot cleaners.
