Homeowners and the Ontario New Home Warranty Program brought actions against a concrete supplier (Bertrand) and a cement manufacturer (Lafarge) for defective concrete foundations caused by the introduction of fly ash.
The trial judge found Lafarge 80% liable and Bertrand 20% liable in negligence for failing to conduct adequate testing.
Lafarge appealed the liability findings and the costs award (which ordered Lafarge to pay 90% of costs due to its conduct at trial).
Bertrand cross-appealed seeking full indemnity.
The Court of Appeal dismissed the appeals and cross-appeals, upholding the trial judge's findings on liability, apportionment, and costs, while varying the judgment slightly to reflect settlements reached during the appeal regarding prejudgment interest and one homeowner's garage.
