❓ Frequently Asked Questions

How does slope affect erosion control product requirements? +

Steeper slopes require more erosion control material because they are more vulnerable to water runoff. For slopes between 10-20%, we add a 15% material buffer. For slopes over 20%, we add a 30% buffer to account for increased overlap requirements and anchoring needs.

What’s the difference between straw blankets and coconut fiber? +

Straw blankets are cost-effective and provide good erosion control for 6-12 months. Coconut fiber (coir) is more durable, lasting 2-5 years, and is better for steeper slopes. Coir has higher tensile strength but costs about 25% more than straw blankets.

How do I account for irregularly shaped areas? +

For irregular areas, divide the space into smaller rectangles, calculate each separately, then sum the totals. Add 10-15% extra material for complex shapes to account for cutting waste and overlapping requirements at irregular boundaries.

How often should erosion control products be replaced? +

Natural products like straw and jute typically last 6-18 months. Coconut fiber lasts 2-5 years. Synthetic mats can last 5-10 years. Replacement frequency depends on slope, rainfall intensity, and UV exposure. Inspect annually and after major storms.
