Newcastle General Hospital
A £300 million deal transforming health services in Newcastle involved moving all acute healthcare services from the Newcastle General Hospital site to new state-of-the art facilities in the Royal Victoria Infirmary and Freeman hospital, effectively consolidating three sites into two.
The hospital design project involved some refurbishment to existing buildings, in addition to the construction of new commercial buildings.
The scheme comprised a new Cancer and Renal Services Centre built to the rear of the existing Freeman hospital, as well as a new 810 space multi-storey car park. The development of the Royal Victoria Infirmary included a new Clinical Block, Clinical Support Block, a Children’s unit, and A&E department.
Waterproofing in a confined space
The hospital design specified waterproofing of basement areas to BS 8102 Grade 1 and 3, with membranes suitable for application on basement walls and below grade slabs. The chosen membrane needed to be suitable for application in a confined site, to permanent formwork.
In addition, drainage was required to manage any hydrostatic pressure on the basement walls. The commercial building design was complicated by expansion joints, which are always high-risk areas below ground.
One of the hospital sites was located on a sloping site with a stepped building, which required semi-basement waterproofing of a grade 3 area. The area also contained a retaining wall that supported earth and required waterproofing to the basement walls.
Complete waterproofing protection
In addition to supplying products, we provided a great deal of design and field support that consisted of site visits and on-site support plus technical and CAD service, as the project contained complex detailing and required problem solving at each step.
To meet the requirements of the hospital design, both Preprufe® 300R and Bituthene® 3000 membranes were used on the basement walls in the grade 1 (multi storey car park) and grade 3 basements to protect against the effects of gas penetration.
Preprufe® delivered a pre-applied waterproofing solution, applicable to below slabs and on confined basement walls.
Bituthene® 3000, a self-adhesive waterproofing membrane, was post-applied to areas constructed with removable formwork, followed by Hydroduct® drainage sheets to protect the membrane.
