Design choices that matter
A containment scaffold is two jobs in one — the scaffold and the envelope. Getting either wrong causes problems.
On the scaffold side, the key decisions are the tie pattern and the wind loading. Sheeted scaffolds behave very differently to open ones, and a tie pattern that’s fine for an open façade scaffold will be under-specified for a sheeted equivalent. Our designs reference the site exposure, the sheeting permeability, and the working wind speed you need to achieve.
On the containment side, the key decisions are the sheeting specification, the joint detailing, and the ground seal. Cheap sheeting fails early under blasting impact, and a poor ground seal lets debris and noise escape the enclosure — usually noticed first by whoever lives next door. We use specification sheeting as standard and we detail the ground seal with a sacrificial fold that can be replaced mid-job if needed.
Programme coordination
The coating contractor usually dictates the programme. Enclosure has to be complete and sealed before blasting can start; blasting has to be complete and clean before coating can start; coating has to be cured before enclosure can come down. We plan the scaffold and containment erection to precede the blast programme, the strip to follow the cure, and any alterations mid-programme to happen inside production breaks.
