New Housebuilders Division

One problem facing housebuilders both before and after development is ground compaction. Open spaces designated for building may suffer years of neglect, constant foot traffic or use of wheeled machinery resulting in panning deep below the surface. Similarly, during the building process bulldozers, diggers, dumper trucks and concrete mixer lorries flatten the air out of the soil in areas that will eventually become gardens and shared grassed areas. Often the land itself may have had previous buildings, and the subsoil contains old bricks, rubble and landfill. All these factors contribute to waterlogging which normal aeration cannot relieve.

 Terrain Aeration’s Housebuilder’s Division has developed the specialist machinery and a full service needed for deep penetration aeration to relieve the problem of heavy compaction and waterlogging. Designed to access tight areas, their Terralift tracked aerator can enter small gardens through a gateway or garage and provide unique one-metre-deep aeration. At this depth, compressed air is released via a probe to fracture the soil and create fissures, allowing drainage and letting oxygen reach deep into the soil. Such work has been carried out for many years by Terrain Aeration for the UK’s leading housebuilders including Taylor-Wimpey, Barratt and Persimmon. A typical recent contract saw them treating ten small gardens and a small open flower meadow for Barratt David Wilson Homes in East Anglia while a project for Taylor-Wimpey was treating an open space so the housing development could be signed off with the council as ‘decompacted’. In this instance, the full-size Terralift machines were used, driving the JCB road breaker probe into the ground. At one metre depth the compressed air, up to 20Bar/280psi, was released from the probe which, on the tail-end of the blast, injects dried seaweed. This sticks to the fissures created as the Terralift process is repeated at two-metre centre spacing on a staggered grid. The seaweed expands and contracts with the soil’s moisture content to allow drainage and aeration.

 The Terrain Aeration process has been in operation for over thirty years, providing compaction relief for new-build gardens, sports grounds, golf courses, amenity areas, racecourses and public spaces. The Terrain Aeration Tree Division provides the specialist treatment for Royal Parks and arboricultural20191210_090038ists throughout the UK.


Terrain Aeration injects polymer

While it may be wet, water everywhere at the moment we will soon be heading into the summer months. That’s when the problems begin for turf and trees. Increasingly, year on year, we are seeing the effects of global warming across our landscape as droughts persist. Sports pitches, golf courses, trees in parks, amenity areas right through to lawns in private gardens will all suffer from the lack of rainfall. Ground becomes hard and compacted to considerable depth and when the rains do come, this often leads to standing surface water and waterlogging.

Suffolk-based Terrain Aeration has specialised in one-metre deep soil aeration to relieve compaction, panning, and waterlogging nationally for over thirty years. While that takes care of the drainage and aeration when it’s very wet there remains the opposite problem of grass and tree roots not getting enough water in periods of drought. It’s a problem addressed by the same machine, Terrain Aeration’s Terralift system, that aerates the soil at depth by releasing compressed air via its one-metre depth probe. As that fragments the soil to create fissures and cracks to allow drainage and aeration, the probe can also inject water-storing polymer. Once in place, the polymer will expand one-hundred fold with rainwater or irrigation water which it stores for the turf or tree roots to take up as needed. It’s a one-way system, so the polymer does not take water from the roots.

In this way, we will be able to make better use of what water we have and it’s a very long-term process as the polymer takes a long time to degrade. Spreading the polymer on the surface is not practical, as when it rains it turns into a gel, making the area dangerous to walk and play on. Injecting it into the ground using the Terralift machine offers the best, most beneficial, and wholly cost-effective method, says the company. Terrain Aeration is the only operator of the Terralift in the UK and the treatment has proven itself since 1985. There are different versions of the machine to treat large open spaces such as sports grounds, golf courses, and avenues of trees to narrow accesses onto bowling greens and gardens.

Terrain Aeration Services are deeply saddened by the death of Her Majesty Queen Elizabeth 11. She showed us all how to cope with life, how to have fun and laugh, but also the power of calmness and dedication. She stood by her own rules and dedication to the people of the UK, a true lady. She will be missed as the most popular and well known person in the World.

Terrain Aeration relief for housebuilders

Terrain Aeration launches Tree Division

David Churchyard has joined Terrain Aeration Services to head up the new Terrain Aeration Tree Division. The company has been treating trees for over thirty years and sees this as an opportunity to expand their specialist service. David brings an extensive wealth of knowledge regarding pests, diseases and fungal growths to trees as well as turf. He was employed as a head forester for twenty-one years on a 6000 acre estate where he was involved in working on and looking after all aspects of the estate’s extensive woodlands. This covered planting heritage oaks, caring for the veteran 900-year-old trees and drawing up management plans for current and future works. To increase his knowledge over the years, David has taken part in many lectures and courses on veteran trees in various locations, including Windsor Castle estate. He also took part in a film on AOD (Acute Oak Decline), the relatively new disease that began affecting many British oak trees since the last quarter of the 20th century. Climate changes are strongly affecting our trees and helping keep them alive is now a priority and one which David relishes in having a key role in.

Terrain Aeration’s Terralift machine is recognised by Tree Officers as a solution to deep aeration and relief of compaction panning around tree roots. The Terralift is the only machine which can aerate around the root zone and put oxygen back into the soil. It breaks up compaction and panning, providing relief from waterlogging and the danger of the waterborne disease Phytophthora. Terrain Aeration’s Tree Division can inspect and advise on suitable treatment without exposing entire areas of tree roots, which may cause undue stress to the trees. One metre deep penetration aeration treatment is used around trees and to treat compacted turf and grass areas. David has joined Terrain to head and expand the division and to get the critical message out there that “it’s the roots that are the root of the problem!” Many trees of all ages are struggling with compaction. This means that essential nutrients are not getting down to the life-giving area of the tree. The message is simple, take care of the bottom-the roots-and the top of the tree will look after itself.

Effective swale treatment by Terrain Aeration

When Pennyfarthing Homes called on Land Products (Wessex) Limited to help resolve an ongoing problem, MD Roger Attrill knew exactly who to bring in. It may look to be not much more than a dried-up pond, but this swale plays an important role in the Alexandra Meadows estate in Lymington. Swales should hold water briefly, then soak away, but this water was retained for weeks after rainfall since the site was completed two years ago as part of the Sustainable Drainage System (SUDS. This is effectively the housing estate’s holding pond to help stop downstream flooding following heavy rain and storm conditions. It was not draining as it should.

“Naturally occurring hard gravels underlying these swales have proved too slow to drain,” says Roger, “we took the opportunity to experiment with Terrain Aeration’s machinery which in a very short period improved permeability greatly.” Land Products provides a comprehensive soft landscaping and grounds maintenance service to Local Authorities, County Councils, the construction industry and commercial clients.

Having called on the services of Terrain Aeration they used their speciality of deep penetration aeration to relieve compaction. The principle works on the basis of penetrating the very hard subsoil with a probe and fracturing it with a blast of compressed air to a maximum of 20Bar (280psi). The process is repeated in spacings so the fissures created interlink and allow full drainage. In this instance, the effect could be seen immediately with a 50mm drop in the standing water in minutes. Within two days, the water had gone completely.

“I’m confident we can make the whole SUDS system work as planned with a bit more time.” Roger says. “I have worked with Terrain Aeration before when they treated compacted gardens for us and they did exactly what they said they would, very straightforward.” Increasingly, Terrain Aeration are called upon by housebuilders and landscapers to treat gardens where during construction heavy machinery has compacted the subsoil around new-build properties.
