Sunnybrook Hospital “M” Wing expansion is a vertical expansion of an existing 4 story building, adding 4 floors and a mechanical penthouse. The final phase of construction required the removal and replacement of the existing porous pavement system with Grasspave2. 1,000 sqm (or 25 rolls of 2mx20m) were installed within a few days. The lane provides access for fire trucks behind the new expansion.

Finished: Sod laid over Grasspave2

Foreground: rings filled with clean sand and the thin-cut sod placed on top.

Rolls of Grasspave2 (2m x 20m)

Applying Hydrogrow mixture and rolling out Grasspave2 over compacted granular base
