Terrain Aeration relief for housebuilders

Terrain Aeration relief for housebuilders: 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 and public spaces. The Terrain Aeration Tree Division provides the specialist treatment for Royal Parks and arboriculturalists throughout the UK.  Terrain Aeration 01449 673783 www.terrainaeration.co.uk

Terrain Aeration launches Housebuilder’s Division

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

Help for housebuilders

Help for housebuilders: The majority of the housebuilding industry has downed tools during the government’s ‘lockdown’ including the UK’s biggest builders, Barratt, Persimmon and Taylor Wimpey.

These giants of the industry remain active however in lobbying government to bring in measures post Covid-19 to help the industry recover as quickly as possible.

Prior to lockdown, Terrain Aeration was playing its own small part in supporting the leading housebuilders with its unique deep aeration treatment of gardens in new build developments. Picture a piece of flat land being prepared for the erection of dozens of houses and you’ll see diggers and dumper trucks, deliveries of raw materials, concrete mixers, bulldozers and brick lorries crisscrossing the site. All of which does a very good job of compacting the ground which may already have a sub-soil layer of rubble, old bricks and general landfill waste. Fine for building on so long as it provides a stable base but not so fine when it comes to setting out the gardens for each property.

Providing drainage systems for back gardens in new build properties is usually a prohibitively costly and unnecessary expense for the builder. The problem is, in a relatively short period and particularly when heavy rains occur, it becomes evident there’s nowhere for the standing water to go, the ground being so compacted. Normal aeration of a newly-laid lawn will have little or no effect, penetrating only a few inches into the heavily compacted area under the topsoil. Terrain Aeration has worked with the builders for many years resolving the problem with their deep penetration aeration system. The company’s range of machines is designed for use from open spaces to tight-entranced, enclosed gardens.

The Terrain Aeration machine hammers a hollow probe one metre into the soil using a JCB road breaker gun (this is needed because the ground is so compact at depth that it needs this hammer to break through).  Once the probe has reached one-metre depth, compressed air is released up to a maximum of 20Bar (280psi). The Terrain Aeration machines are the only ones using such high air pressure, which is needed to fracture and fissure the soil. The probe is withdrawn and the process repeated using spacings on a staggered grid pattern – this means that each shot interconnects with the previous ones. On the tail end of the air blast, dried seaweed is injected which sticks to the walls of the fractures and fissures and, over time, expands and contracts with the moisture content in the soil – similar to “breathing” underground.   The 1½” probe holes created by the Terrain Aeration machine are backfilled with aggregate to provide a semi-permanent aeration/ventilation shaft, helping to keep the whole aeration process working. Terrain Aeration is already set to work with the housebuilders once again, as soon as the current restrictions are lifted, and to contribute to getting the housing market back on track.
