Why is proper soil preparation necessary before installing ECBs or TRMs?

Proper soil preparation is critical before installing Erosion Control Blankets (ECBs) or Turf Reinforcement Mats (TRMs) because it directly influences the success of seed germination. When the soil is well-prepared, it creates an optimal environment for seeds to take root and grow. Factors such as soil texture, compaction, moisture retention, and nutrient availability are all affected by soil preparation.

When soil is adequately prepared, it enhances seed-to-soil contact, which is vital for germination. This also helps manage moisture levels, ensuring that seeds receive enough water without becoming overly saturated, which could impede growth. Good soil preparation can improve aeration and drainage, preventing issues that might arise from poor soil conditions.

While other factors, such as preventing erosion and meeting aesthetic regulations, may be important, the primary focus of soil preparation is to establish a healthy environment conducive for seeds to germinate and ultimately thrive.
