Fill and Backfill for Foundations - Webinar

  • ID: 4410017
  • Webinar
  • 90 Minutes
  • Lorman Business Center, Inc.
1 of 4
Understand the techniques and equipment for selecting, placing and compacting fill and backfill.

Addressing geotechnical issues is one of the most challenging problems faced by engineers and constructors engaged in design and construction of foundations for buildings and other infrastructure features such as tunnels, shafts and hydraulic structures. This is because it is usually difficult to have an understanding of complex underground conditions until they are actually encountered during construction. These challenges need to be addressed with a disciplined approach consisting of pre-design subsurface exploration excavation methods that properly handle, store and utilize excavated, borrow and imported material foundation preparation including fill and backfill and stabilization methods that may be employed when unsatisfactory soil and rock conditions are encountered. This material will provide you with an overview of challenges they may be faced with their future projects, and the methodologies and techniques they may use to address them.

Learning Objectives
  • You will be able to identify special problems.
  • You will be able to discuss foundation excavation.
  • You will be able to explain stabilization of subgrade soils.
  • You will be able to review foundation preparation.
