Molson Peak Brewery in Chilliwack (BC) needed to have a wastewater treatment plant facility built. Liquefaction treatment was required under the structure.<\/p>\n

Ground Conditions<\/h3>\n
\n
\n

The site\u2019s subsurface stratigraphy consisted of the following:
\n\u2022 Approx. 0.5m of compact to organic ground;
\n\u2022 Underlain by 4m of soft to firm clay to silty clay;
\n\u2022 Underlain by 7m of loose to compact silty sand to sand susceptible to liquefaction;<\/p>\n

Groundwater was encountered at approximately 2m from the ground surface.<\/p>\n

Vibro Replacement stone column densification was required beneath the new wastewater treatment plant in order to prevent settlement caused by soil liquefaction in the event of an earthquake.
\nMenard utilized Wet-top-feed Stone Column<\/a> installation techniques which was the preferred method of the General Contractor. Stone columns were installed to 11m depth on a regular grid pattern to meet the specified CPT tip resistance performance-based requirements.<\/div>\n
\n

Densification work began with an initial trial area consisting of 20 stone columns to assess the effectiveness of the proposed methods and stone column spacing. Production work applied similar methodologies to those proven successful in the trial area.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>
