Shear Walls, Moment Frames and Foundations

One-sided concrete applications. where only one side of the formwork is installed, can benefit greatly from shotcrete. With this method, up to 95% to 100% of the required formwork can be eliminated, leaving only construction joints and perimeters to be framed. 5hotcrete also eliminates the need to engineer t he forms, as there are no internal pressures from the fresh concrete. However, for double-sided walls, a rigid back form or stay form must be used in conjunction w ith shotcrete

Support of Excavation, Stabilization and Slope Protection

Usually, these structures serve as temporary supports during the construction process, providing an extra layer of protection for workers. They are typically buried o r covered by the structural applications once the construction is completed.

Concrete Repair

Shotcrete is the most efficient, economical, and effective repair process for concrete. It out performs form and pour or form and pump applications. While p roperly prepared surfaces, water satu ration (550), and application techniques are crucial for all repair types, shotcrete eliminat es the need for bonding agents and formwork, and typically exceeds the requirements outlined in the specifications.

Tidal Work

Working w ith the tide can be extremely challenging due to t he limited w indow of availability that changes every day. How ever, shotcrete can make this process much easier by eliminating the need for formwork and allowing for immediate application of concrete after placing the rebar. To achieve this, special equipment is used to inj ect a chemical directly into the concrete before it is shot into place. This chemical accelerates the curing process of the cement paste, enabling the concrete to reach init ial set before the tide comes in.

Mock Ups and Testing

A mock-up is a test t hat assesses the abi lities of craftsmen install ing p roducts w it hout risking any production work. It is built from a snapshot of the project and subjected to destructive testing, allowing inspectors to assess the competencies of the contractor and crew, compression strength of the concrete, and nozzleman ability. The panels are cored or saw-cut to reveal t he encapsulated rebar and inspect for defects or voids in t he sample. In most cases, mock-ups demonstrate t he surface finish t hat w ill be applied.
