The stratigraphy of the site was composed of 3 distinct layers before reaching the rock:

• Topsoil with a thickness of 0.10m to 0.20m on all the boreholes drilled by GHD (2022) and Solroc (2021).
• An embankment with organic matter with a thickness between 0.6 and 4.00 m
• A silty clay deposit between 16.89 m and 19.82 m thick in BH-08 and BH-09. The silty clay deposit was to be divided into two distinct sections:
• A clayey crust with a thickness of 3 meters;
• A soft to firm clay with a thickness of approximately 13.8 to 16.8 meters;
• A glacial till was intercepted directly under the silty clay in borehole BH-09. The rock was drilled in boreholes BH-08 and BH-09 to a thickness of 1.5m to 2m

The water level was measured at trenches TP 15 to 19 and TP 22 to 25 on February 10 and 11, 2022, with a rise in the water level to the highest of 39.70 m. On June 14, 2022, the water level was measured at 39.81 at the F-2 borehole drilled by Solroc.
