Eco Foundations recently completed a contract for Dawnus Construction to install approximately 1000 VCC piles of 350 mm diameter to a depth of 9 m for a new recycling centre in Rhyl, North Wales.
The piles were installed using an RTG RG19T telescopic leader rig with 125 tons resonance free variable moment vibrator. The highly powerful rig was able to obtain outputs of in excess of 80 piles per day resulting in a very competitively priced project when compared to driven cast in situ or CFA piling.
A contract to install a king post retaining wall with concrete panels has recently been completed for Beale Homes in Willerby, East Yorkshire.
The king posts were installed by a mini crane into 600 mm diameter holes drilled through heavy chalk with a compact CFA piling rig. The small crane and rig combination was chosen due to the restricted access nature of the site.
500 linear metres of 7 m deep cut off wall has recently been installed for the Environment Agency at Goole using soil mixing technology. The soil mixing involved the use of a binder to create an impermeable cut off wall to stop the flow of water through the flood defence embankment during times of flooding.
During September 2009 soil mixing provided a successful solution to British Waterways at the Shropshire Union Canal in Shebdon on the Staffordshire - Shropshire border. The canal had been leaking for many years and even with the introduction of sheet piles on both sides the water was not able to be stopped from dissipating through the canal bed and out the sides of the embankment. Eco Foundations were able to respond immediately to the emergency situation utilising it's mass soil mixing rig to solidify the base of the canal into a clay-like substance utilising a cement/bentonite binder.

Flood defence retaining walls and CFA bearing piles installed in Carlisle, Cumbria as part of flood alleviation scheme on behalf of the Environment Agency.
As you can see from the photo the access to the site was extremely restricted so we selected a CZM EM600 compact CFA piling rig to install the majority of the piles for the flood defence retaining walls and the CFA bearing piles.
King post retaining wall and CFA foundation piles installed in courtyard of building in London as part of extension works for a listed building.
The access to and within the site was extremely restricted so we selected a CZM EM600 compact CFA piling rig to carry out the works.
This CFA piling rig was initially used to bore the holes required for the kingposts to be installed to create the retaining wall, and then moved onto install 450 mm diameter CFA foundation piles to 8 m depth throughout the site as required.

Eco Foundations install retaining walls for new Mosque at Upon Park, London. Two methods of construction are being utilised. A contiguous bored pile wall is being installed using a high powered CFA piling rig, 450 mm piles are being drilled to a depth of 17.5 m.
