On-Site Concrete and Grout Production

We are able to produce concrete for a construction contractor who needs as little as 3 yards in one day or as much as 1,500 yards each day for months! We have the resources to set up on-site for any period of time. With portable silos, mobile concrete batch plants, trucks and loaders, we can set up and start producing concrete in a matter of a few hours, and concrete production is continuous. No productivity is lost waiting for concrete trucks to arrive or make round trips through traffic. Equipment and labor can be efficiently scheduled. On-site concrete production allows our customers to tailor the concrete production to their needs in product, volume and schedule. We help to coordinate and plan out the project using our expert knowledge and years of experience. By being on site, we can also provide special cements like Rapid Set® or latex-modified concretes. Rapid Set hydrates (sets) to strength within one hour. That kind of timing needs expert handling and we can do it.

Concrete Production using Mobile Batch Plants in Remote Locations

We specialize in concrete projects in remote locations. These types of projects are right up our alley. They can be on mountain tops, on an island, on barges or vessels — the locations can be anywhere. We excel in these types of situations where regular ready-mix is too far away or not practical and production can be stopped or started at any time.

Soil Remediation and Environmental Cleanup on Contaminated Soil

The George Throop Company performs soil and environmental remediation. We specialize in stabilization/solidification technology. Stabilization and solidification technology relies on the reaction between a binder and the soil to stop, prevent or reduce the mobility of the contaminents. Remediation usually has regulatory requirements involved based on the assessments of human health or ecological risks in place.

Color Matching for Concrete and Grout

Over the years, the Throop Company has been called on to match many different colors from old historical structures to new projects that need additional material. Our services are a blend of scientific materials knowledge and hands on artisanship. Our staff can recommend different colors along with possible chemical and physical aging techniques to help you get the perfect look you are striving to achieve. Our trucks are equipped with custom designed pigment feeders that are calibrated for each job to insure a quality job every time.

Custom and Unusual Concrete and Grout Mix Designs

The George L. Throop Company is often called on to produce concrete on jobs that no one else would like to take. Often times, this means creating custom mix concrete designs. This can entail handling special raw materials, particular chemical admixtures, with environmental goals or specific performance characteristics. We go through strict quality control testing to ensure the customer's mix design is produced.

Emergency Response Program and Non-standard Work Times

We will work around your schedule — that means that there might be times when the work needs to be done at 2:00 a.m. in the morning when there isn't a lot of traffic or usage. We'll be there for you — whenever you need us.

Filter Media
