MARKHAM Case Study – Canterbury University Basement

University of Canterbury Maths Science Basement in 2009 2 scaled

At Christchurch University in 1998, the tanking system in the basement of the eight-storey Maths & Science Building had failed. Groundwater levels were above the height of the basement, as the site adjoins a small watercourse called Ilam Stream; and pressure seepage was increasing at a significant rate.

With four “six inch” de-watering pumps operating, the basement floor was still largely covered with water, and water was seeping in through cold joints in the walls and lift shafts up to nearly 2 metres above the floor level.

The urgent objective was to arrest this water ingress and permanently prevent reoccurrence.
