The University of Liverpool, Active Learning Labs

Background

The Engineering Department was enthusiastic about the idea of illuminating the 826 glass panel façade to the building. The Lab is lit with hundreds of LEDs and can be seen as far away as Wirral.

Problem

The new roof area was to be covered with nearly a hundred concrete plinths that supported the track to the window cleaner’s cradle, along with many other roof protrusions. The walls were also to have hundreds of angle brackets, penetrating through the wall off the steel work to support the glass rain screen cladding which was illuminated at night.

Solution

Holloway Cook Associates installed a new liquid applied waterproofing system that could efficiently protect the building and be easily applied to the numerous details on the walls and roof area.

Christ the King, Southport

Background

Christ the King Catholic High School and 6th Form College, is a large Roman Catholic secondary school located in Birkdale, Southport. The school was originally built to be temporary; however it is still standing after many years and has approximately 1200 pupils ranging from 11 years old to 18 years old.

Problem

The aluminium framed GRP roof structure covering the gymnasium was severely warped and degraded; in hot weather conditions panels would slip out of place and  every time it rained it leaked, which is not good for a gymnasium floor. Replacing the roof structure would have swallowed the schools entire maintenance budget for the year.

Solution

Holloway Cook Associates  were able to leave the existing roof structure in place and make it watertight for a guaranteed period of 20 years by installing a totally elastomeric liquid applied reinforced membrane which could accommodate movement through hot and cold weather conditions .
