ASUC is an independent trade association originally formed by a number of leading contractors to promote professional and technical competence within the subsidence industry.

Membership has now been extended to include a comprehensive range of specialist domestic services in: underpinning and subsidence repair techniques, engineered foundation solutions and retrofit basement construction.

Any contractor wishing to join ASUC must first undergo a technical, health & safety, insurance and financial audit and make a commitment to prescribed safety procedures.

ASUC members can offer an insurance warranty on all the works carried out under contract.

Publications, including ASUC's three Guideline documents on: Basements, Structural Repairs, and Underpinning & Mini Piling Operations, are available to download free from the publications page.
