What's the difference between wet mix and dry mix shotcrete pumps?

Wet mix pumps convey pre-mixed, ready-to-place concrete and add compressed air only at the nozzle, offering more consistency and less waste for large continuous pours like tunnel linings. Dry mix pumps convey dry material and add water at the nozzle, giving the operator more control for smaller or more intricate jobs like pool shells and repair work. Neither type is universally better, the right choice depends on the application and required control. Sparkline Group carries both wet and dry mix shotcrete pumps. Discussing your project scope helps identify the better fit.
