Why East River

Built to endure

We understand agricultural, residential, and civil projects each require different concrete mix designs and properties — and we batch accordingly.

Standard & Custom Mix Designs

Standard structural mixes from 3,000 – 5,000+ PSI, or fully custom formulations with accelerators, retarders, plasticizers, or fiber reinforcement.

Ag-Specialty Concrete

Chemically resistant mixes purpose-built for animal confinement floors, barns, and highly acidic silage storage slabs.

Front-Discharge Fleet

Modern front-load mixers let the driver pull straight in and place concrete precisely — less wheelbarrowing, faster pours.

Freeze-Thaw Formulated

Designed for South Dakota's brutal winters — air-entrained mixes that resist cracking through seasonal cycles.

Reliable Scheduling

Same-day and multi-truck coordination for continuous pours. Dispatch confirms your window and honors it.

Local Batch Plant

Based north of Platte, SD. Serving Aurora, Brule, and Charles Mix counties with locally batched ready-mix.
