Grouting during Mackinac Bridge construction (4 of 11)

Grout was pumped down the grout pipes to the bottom of the aggregate layer. As the grout raised through the voids between the aggregate it displaced the water that was above it. Before the grout "set" the pipes were pulled up to a prescribed location, more aggregate was added and more grout was pumped in until the foundation reach the desired elevation., Electronic reproduction of photograph.
