Capitol Visitor Center | Washington D.C.

A massive new subterranean addition beneath the US Capitol Building required an equally massive support of excavation system. We were contracted to install a 130,000 square foot, reinforced diaphragm wall along with 380 linear feet of “panel” jet grout to create a deep water cutoff system.

World Trade Center Vehicle Security Center | New York, NY

A new facility for the screening of vehicles entering the World Trade Center was commissioned post-9/11 as a comprehensive safety measure. The five-story basement structure required a water-tight excavation. We installed 122 jet grout columns as part of the earth support and water cut-off portion of construction.

What is jet grouting?

Jet grouting consists of breaking up the soil with a high-pressure jet in a predrilled borehole and mixing the loosened soil with a cement grout. Nicholson's range of jet grouting processes include single (cement only), double (cement with air) or triple (cement with air and water) fluids.

How does it work?

Proprietary nozzles are used to distribute grout in a specifically designed geometry and arrangement for the project.

Why do you need jet grouting?

Nicholson's jet grouting method is suitable for all soils (from clay to sand and gravels) and is capable of producing a wide variety of structures through a combination of columns and panels underground.
