Drumheller Fountain was constructed in 1909 for the Alaska Yukon Pacific Exposition. Due to the age of the concrete pond substantial water loss was occurring and the university needed a cost effective long term alternative to replacing the pond structure.

Layfield designed and installed a 45 mil CSPE liner with a 12 oz non-woven geotextile cushion under the liner on the floor and walls. The design included safety provisions for a grab handle around the exterior wall and new access ladders. The design had to fit with the current piping system for the fountain.
