Terrain Aeration

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 20^th 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.

Walking on air in Greenwich Park

The oldest enclosed Royal Park, Greenwich covers 74 hectares on top of a hill where visitors enjoy sweeping views across the River Thames to St Paul’s Catherdral and beyond. There has been a settlement on the site since Roman times, and Greenwich has always had a strong association with royalty. Historic tree areas date from 1660 when Charles II was king and eleven original trees from the period can be found in the park. In 2019, the park had over five million visitors and with its view and attractions – there’s even a Saxon burial mound – it is no wonder when the pandemic struck there was a massive increase in visitors in the first year of lockdown.

“It was like bank holiday every day,” says Adam Stoter, Greenwich Park’s Technical Officer. “Greenwich Park offered an open-air space when there were few places people could go. The trouble was, the added footfall compounded the growing problem of compaction in and around the tree areas.”

The Royal Parks’ flagship project ‘Greenwich Park Revealed’ had already begun to restore the 590-year-old park to protect and share its heritage. They aim to go above and beyond in tree care and management and it was a natural progression to bring in the specialist services of Terrain Aeration’s Tree Division. The company has been treating tree areas in Royal Parks for many years and, in the case of Greenwich this year, applied their technology across 15,000 square metres. Where there is heavy compaction it is essential to break up the soil at a depth greater than the tree roots, other than the main tap roots which go straight down, to allow excess water to drain away and help stop anaerobic conditions and rotting of the root system.

The Terrain Aeration Terralift machine sends a probe to a depth of one metre where compressed air is released to a maximum of 20Bar (280psi). This blast of air fractures the soil and creates fissures which interlink as the Terralift repeats the process on a grid system of two-metre spacings. As the probe withdraws at the end of the air blast, dried seaweed is injected which sticks to the fissure walls, expanding and contracting with moisture content in the soil to keep the area ’breathing’. In most cases, the area treated will be one-metre inside and one-metre outside the canopy drip line to reach beyond the growing roots, increasing the percentage of oxygen intake and allow maximum drainage. In all, Terrain Aeration treated around 15,000 square metres to help ensure the future of the historic tree areas where visitors will literally walk on air.

Buckingham West End Bowls Club

Received from the groundsman at Buckingham West End Bowls club after heavy rain in July:

Good evening Lynda

Just an update.  We had a tremendous downpour one evening earlier this week (picture attached).  The following morning the green was playable although a bit soft.  Before you did your work, we would have had a large puddle for a few days so a big success

Terrain Aeration launches housebuilder's division

Over many years, major house building companies have called on Terrain Aeration to decompact back gardens and community areas of new-build developments. During building, the unavoidable combination of diggers, dumper trucks, bulldozers, concrete mixer lorries and parked vehicles take their toll on the soil, flattening the air out of it. Eventually, the areas that become the gardens and shared grass areas, which may already have a sub-soil layer of rubble, old bricks and general landfill waste, becomes overly compacted. The result is waterlogging and panning requiring very deep aeration to cure the problem.

Terrain Aeration has provided the solution to this for some of the UK's biggest builders including Barratt, Taylor-Wimpey and Persimmon. The Terrain business has grown in the sector to the extent they have formed their Housebuilder'' Division, headed by Elly Fletcher. Three new staff join her to form the specialist team that will concentrate on the house builders' needs. Terrain Aeration's Managing Director, David Green, has built different types of machine to enable access to the gardens through single gates and garages. He says:

"Our Terralift machine has proven itself over the last 30 years in aerating and decompacting soils. It is the ideal way of getting oxygen back into the soil structure, non-invasive and no mess. This does not replace the: "no need for drains issue" but it is cost effective and works. Putting in new drains will still leave you with compaction panning in-between the drains, so using Terrain Aeration in the first place is a step in the right direction. Once a garden has been aerated using Terrain Aeration's machinery, nature will be able to help with the rejuvenation of the soil structure - so this treatment would not be required again."

Under normal circumstances, Terrain Aeration works nationwide and their teams are available, subject to ongoing Covid-19 restrictions, to carry out deep aeration relief for waterlogging and flooding for house builders, sports grounds, amenity areas, golf courses and public spaces. Enquiries from house builders are welcomed with a new email address: aerationterrain292@gmail.com and by calling Terrain Aeration 01449 673783 www.terrainaeration.co.uk
