Don't get caught short. Learn how to accurately estimate waste and uneven subgrade for any concrete slab.

Professional concrete operations require more than just technical skill; they require a deep understanding of the variables that affect every pour. In this technical deep dive, we explore how the 10% rule: why you always need extra impacts the efficiency and quality of your next high-performance project.

Field Logic Matrix

"Consistency is the backbone of structural integrity. Whether you're managing pump pressure or monitoring ambient temperatures, the goal remains the same: zero-blockage delivery."

When working with modern pump trucks and high-performance mixes, the margins for error are razor-slim. Standard structural concrete often loses significant slump over long distances or during vertical lifts. Our field-tested logic and real-time calculations provide the roadmap for adjustments at the truck to ensure perfect discharge at the hose.

Optimization Framework

By leveraging precise data points—initial slump, line length, and diameter—operators can move from reactive adjustments to proactive management. This level of technical oversight is what separates elite contractors from the competition.
