Project: Decompacting turf after concert
Client: St James's Park, London
Contractor: Terrain Aeration
The Olympic Handover Concert drew thousands of people to London last summer - but the increased footfall and vehicle activity meant 6,000sq m of compacted turf at St James's Park had to be treated following the event.
Terrain Aeration was hired under contract by Enterprise to treat the turf areas with 1m-deep compressed air decompaction. St James's Park assistant park manager David Ellis said: "We were left with severe compaction in the area behind the temporary stage, which had been used to store staging equipment and as a lorry park."
Terrain Aeration employed its largest terralift machine, Airforce, along with a smaller, lighter model, Airforce Scamper, to treat the area. The work involved inserting a 1m probe and injecting compressed air at 2m spacings on a staggered grid pattern. Dried, milled seaweed was injected on the final air blast and the probe holes were filled with Lytag aggregate.
