Shotcrete Retaining Walls


Shotcrete is a pneumatically applied low-slump concrete that is blown onto the receiving surface with compressed air. Shotcrete has a relatively low water/cement ratio, high cement content, and typically small aggregate not exceeding pea gravel size. High compressive strengths in excess of 5,000 psi are commonly attained. The sticky nature of shotcrete allows it to be placed on vertical and even overhead surfaces without the need for formwork. With proper quality control, a wall surface can be built out to an 8- inch thickness or more in a single pass.

Anchored Retaining Walls: How Do Tiebacks Work?

Image
Tiebacks are used to provide the lateral resisting force for many of the excavation support systems and anchored retaining walls that Schnabel builds. They are constructed by grouting a high strength steel bar or strand bundle into the soil or rock behind the failure surface of the retaining wall. After the grout has cured, every tieback is tested, and the load is locked in to limit movement. Learn more: https://posts.gle/s3Ekj

How Do You Stabilize A Landslide?

Image
  A landslide occurs when the driving forces on a soil mass exceed the internal resisting forces of that soil mass and the land starts to move. Schnabel’s landslide repair service utilizes proven techniques to stop or prevent a landslide including installing tieback anchors, soldier piles, and/or micropiles to provide additional external resisting force.
