Centenary Health Centre
The Shoniker tunnel is a pedestrian tunnel that connects the Rouge Valley Centenary Hospital and Shoniker Clinic beneath Neilson Road. The project aimed to repair the failed expansion joints within the tunnel, repair leaking cracks as well as concrete surfaces. This involved excavating the tunnel and installing new waterproofing on the tunnel walls and roof slab.
The work needed to be completed during the winter months, which required heat and hoarding for the waterproofing application, as well as phased closures of the road and the Hospital Emergency Entrance which was very problematic. Vector Corrosion Technologies, RJC Engineers, and Koster proposed an alternative solution; the repair strategy was to complete a curtain wall area injection method using a water based elastic acrylic gel waterproofing system (Koster G4) with all repairs to the entire tunnel structure undertaken completely from the interior.
This innovative design solution saved the client several hundreds of thousands of dollars and avoided the significant site and environmental disruption that would have been caused by the original proposed excavation scope.

Project Profiles
Kirkland Gold Mine
There was widespread water ingress through cracks, joints and corners in the foundation walls of the mine's shaft. The repairs had to be completed without disrupting the mining operations or moving/damaging the many electrical/mechanical fixtures on the walls. The Macdero Injection Services team was able to complete the waterproofing of the entire building, ensuring the structure and everything inside are protected from water ingress.

Harbour Square
The building is located several hundred meters from Lake Ontario. Every spring when the lake levels begin to rise, the building would experience water ingress from under the slab and adjacent foundation walls. Koster Gel G4, Koster Gel S4 and Koster NB Grey were all applied and stopped all water ingress, sealing the 3 floor below grade elevator shaft from the top.

University of Toronto
University of Toronto (Mississauga Campus) elevator pit leak repair project where, when Macdero Construction (Ontario) Ltd. Injection Services arrived on site, the bottom of the pit was filled with 4 inches of water. The GC informed them that the water ingress was constant and drains/pumps could not keep up. Koster Gel S4 was successfully placed, stopping all water ingress.
