Smart Batch® Technology
Every Batch. Weighed. Archived.
Washington’s Smart Batch®-equipped gypsum concrete crew. A trailer-mounted, computer-controlled batch plant weighs every ingredient of every batch — and archives the record to the cloud for your project file.
Capable of up to 40,000 sq ft per day — one weighed batch every 75 seconds. Schedule risk, engineered out.
Batch-by-batch weighed reporting, archived to a cloud server. QC reports delivered for the GC’s closeout file.
Enclosed bulk batching cuts jobsite airborne dust ~94% (per Smart Batch Systems) — and eliminates the bag-breaking position entirely.
“Ask any other gypcrete crew in Washington for a per-batch mix report. We’ll wait.”
