ASUC's activities are focused around key domestic techniques and practices including subsidence repair and underpinning, retrofit basement construction, engineered foundation solutions and mini piling operations.

ASUC is an independent trade association originally formed by a number of leading contractors to promote professional and technical competence within the subsidence industry. It works with and across a large number of organisations, partners and supporting bodies to deliver a range of highly valued activities and services on behalf of the sectors and members they support.

Kevin Hague, managing director of Aarsleff Ground Engineering said: "We are thrilled to share our knowledge and experience of the industry, and support ASUC and its member's in the drive to improve project delivery capability across all of the specialist techniques and practices the association promotes".

Aarsleff is already experienced in restricted access piling operations. In June last year, it installed mini piles for a new residential development on behalf of the main contractor J Tomlinson. Specifically, Aarsleff installed 16 No. 300mm Sectional Flight Auger piles utilising a 14t restricted access piling rig. Due to existing tree preservation orders in place on several mature trees, the rig was selected to provide minimal disruption. Apart from some localised pruning to the trees, the rig was capable of working from the existing tarmac and on a reduced spec piling platform.

In 2017, McLaren Construction awarded Aarsleff the design and build contract for the construction of a new cinema and retail development within The O2 Arena in South East London. Aarsleff's scope of work included the design and installation of 21No. 18m 340mm diameter ‘restricted access piles' situated beneath 2No. Quadro-pods which had to be pitched in 4m segments and welded by Aarsleff on-site during installation. Due to the height restriction, Aarsleff utilised its bespoke Banut 500 limited headroom piling rig to solve this issue.
