Solutions for Bridges
The infrastructure of the United States is home to over 600,000 bridges. Existing bridges may be slated for expansion or complete replacement. New bridges need the most economical foundation, and can benefit from value engineered alternates. Foundation piers can be threatened by scour or soft soils. Compressible soils can result in excessive settlement of embankments. Over time, timber piles can deteriorate. Liquefiable soils can pose danger during earthquakes. Specialty piling and grouting techniques allow precise treatment from ground level or from the bridge itself, to reestablish foundations in suitable bearing stratums, densify soil around settling piers to arrest settlement and increase bearing capacities, or protect foundation elements from scour. Old and new bridges benefit from Hayward Baker’s decades of advancement of geotechnical construction techniques.
