Castlebrook High School – Bury

Construction Sealants Ltd are pleased to announce the new contract with Galliford Try at Castlebrook High School. We started on site in March 2019, work will include carrying out low modulas sealant to external windows, doors, cladding and wall expansion joints up to a 30mm joint, pointing floor joints including saw cuts, sealants to all sanitaryware and internal works along with sealing areas with intumescent & acoustic fire rated acrylic.

Castlebrook high school is a part of a £4.4 billion Priority School Building Programme to rebuild and refurbish school buildings in the worst condition across the country. The current school, built in the 1970s, is unfit for purpose in various ways, needing rewiring, having single glazing and inadequate ventilation and heating. Repairs and upgrades were unable to be carried out due to asbestos in the school.

The new three-story main school building which will accommodation for 935 pupils will be created and parts of the existing school would then be demolished. The school will be transformed into a modern, attractive building with a games area, 100 car parking spaces and plans to retain the existing sports hall, construction center, and all-weather pitch.
