Site Investigation – Major redevelopment Cardiff

Envirotreat was commissioned to carry out a second phase of ground investigation for the proposed Cardiff Arena development, following on from the successful completion of the Phase 1 works in September 2020.

The works included the drilling of 8No. cable percussive and rotary follow-on boreholes to a maximum depth of 35m, trial pitting and soakage testing. In total, Envirotreat has drilled more than 350m of boreholes across the site, through some very difficult ground conditions.
