Pre-Sloped Drainage Systems
Engineered solutions for optimal drainage performance and installation efficiency
Why Choose Pre-Sloped Drainage?
Technical Advantages
Pre-sloped drainage systems offer significant advantages over traditional poured-in-place systems. According to the International Plumbing Code Section 708, proper drainage slope is critical for effective water management. Pre-sloped systems ensure:
- Consistent 0.5% slope meeting ASTM F2418 requirements
- Reduced installation time by up to 40%
- Elimination of field slope calculation errors
- Improved hydraulic efficiency
Performance Benefits
The American Society of Civil Engineers (ASCE) emphasizes the importance of proper drainage in infrastructure design Pre-sloped systems provide:
- Predictable flow rates meeting EPA stormwater management requirements
- Reduced sediment accumulation
- Improved maintenance access
- Long-term structural integrity
