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: subsidence repair and underpinning,  retrofit basement construction and engineered foundation solutions.

Contractor wishing to join ASUC must first undergo a technical, health & safety, insurance and financial audit and make a commitment to prescribed safety procedures.  Non contracting companies and consultants may also apply using the appropriate forms.

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.
