Proper Slope Assessment for Erosion Control
When assessing slopes for erosion control, it’s crucial to recognise how steepness and gradient affect erosion risk. A thorough slope assessment helps identify gradients; slopes steeper than 5% often need stronger erosion control measures. For longer slopes, particularly those over 15 metres, the increased volume and speed of runoff can heighten erosion potential. Consider using the Revised Universal Soil Loss Equation (RUSLE) to estimate soil loss based on slope steepness and other factors.
Additionally, recognizing the impact of erosion is essential for developing effective mitigation strategies and ensuring the longevity of the construction project. Adjusting slope geometry through grading techniques can create a more erosion-resistant slope by reducing steepness where feasible. Properly managing aggressive rainwater runoff is vital in preserving the stability of the slope and preventing further erosion issues.
Creating a Solid Base to Prevent Erosion
Creating a solid base is crucial for preventing erosion in resin-bound gravel applications. Start by removing any existing surfaces and excavating to a depth of at least 220mm, adjusting based on site conditions.
Ensure the excavation is wider than planned to accommodate edge restraints, which will provide additional stability and help resist lateral movement.
Next, lay a permeable sub-base using MOT Type 3 hardcore at a minimum depth of 150mm, compacting it well for maximum stability. The type of sub-base significantly impacts installation success and durability, ensuring the longevity of the surface.
Avoid placing granular sub-bases directly under the resin surface; instead, a rigid base like concrete is essential for effective erosion prevention.
Before applying the resin, check the moisture levels of the surface and clean it thoroughly to ensure strong adhesion, providing long-lasting protection against erosion. Additionally, implementing suitable drainage channels can further enhance the effectiveness of your base in managing water flow and preventing erosion.
Selecting the Right Aggregates for Stability
Once you’ve established a solid base, the next step is to choose the right aggregates for stability in resin-bound gravel systems.
Opt for angular stones sized 2-5mm, as they provide excellent grip on slopes, much like winter tyres. Ensure the texture enhances traction, especially in wet conditions, while allowing for efficient drainage. This is essential because resin-bound gravel acts like a permeable sponge, allowing for effective rainwater management. Proper grading of the aggregates is also vital for ensuring a tighter fit, which contributes to the overall strength and durability of the surface.
It’s crucial that the aggregates are compatible with the resin binder to ensure strong bonding and prevent deterioration.
Select eco-friendly aggregates from sustainable sources to align with environmental goals.
Also, consider factors such as load-bearing capacity and chemical resistance for long-lasting performance.
Lastly, pick aggregates that are visually appealing and blend well with your landscape, enhancing both functionality and appearance while minimising maintenance needs.
