Slicing eliminates wind related problems. Problems with windy conditions were discussed in the trenching section, but the wind has no impact on the slicing method. The fabric unrolls directly into the slit and is compacted without having to worry about the wind. The slicing method eliminates many of the labor problems related to silt fence installation. Most poor soil conditions are managed by the slicing method, most digging and back-filling tasks are eliminated, and the operator is responsible for quality and consistency.
Mechanization greatly improves the quality and consistency of silt fence.
The tommy dramatically reduces labor costs, while improving installation quality. Just like a factory production line, separating the installation, posting, and attachment phases greatly increases the overall productivity. Productivity means profitability. Your significant profit doesn't come from saving labor costs. The significant profit comes from your gross profit per foot of material installed.
