How we work

From soil data to integrity testing

01
Soil data review

We review CPT/borehole logs and shop drawings before settling on method and plant.

02
Rig mobilisation

Rig and crew are matched to site access, pile diameter, and design depth.

03
Drilling & concreting

Verticality, concrete slump, and pour volume are recorded pile by pile.

04
Reporting & integrity testing

Complete piling records and PIT/PDA testing to project specification.

Why Alpha

“You cannot build a great building on a weak foundation.”

— Gordon B. Hinckley

Foundations disappear from view once the building stands. That is precisely why we document every pile — complete piling records, PIT/PDA testing, and a schedule we keep.
