Aero General Service Channel: Drainage Pipes Discussion

Host Introduction

• Host: Corey Bartolotti
• Focus: Comparison of corrugated and PVC pipes for drainage.
• Key assertion: Application determines the choice of material.

Corrugated Pipes

Usage Characteristics

• Original Design: Meant for agricultural fields.
• Depth of Burial: Effective when buried 4-5 feet deep.
• Root Intrusion: Less effective in residential settings where roots from trees and shrubs can intrude.
• Cost: Inexpensive due to the need for large quantities in agriculture.

Historical Context

• Previously, terracotta clay pipes were used in agriculture for drainage.
• Transition to plastic corrugated pipes for easier installation and cost-effectiveness.

Residential Use of Corrugated Pipes

• Challenges: Not suitable for shallow burial common in residential areas (1-2 feet).
• Root Problems: Prone to root intrusion due to the shallow installation.
• Material: Made from recycled plastic, prone to failure in residential settings.

HDPE and PVC Pipes

HDPE (High-Density Polyethylene)

• Suitable for Northern Climates: Adaptable to expanding and contracting due to freeze-thaw cycles.
• Recommended Product: The FDM (French Drain Man) pipe for its durability and resistance to crushing.

PVC (Polyvinyl Chloride)

• Climate Specific: Best for non-freezing climates.
• Type: SDR35 is favored for its cost-effectiveness and compatibility with thin-walled sewer fittings.
• Limitations: Not recommended for freezing climates due to rigidity and potential for cracking.

Schedule 40 PVC Pipe

True Schedule 40 vs. Cellular Core

• True Schedule 40: Solid PVC, more expensive.
• Cellular Core Schedule 40: Not solid; has inner cellular structure; prone to chipping and failure.
• Cost Differences: True schedule 40 is significantly more expensive.

Dual Wall and Triple Wall Drainage Pipes

Dual Wall Pipes

• Structure: Smooth interior for strength; not flexible but durable.
• Usage: Good for Northern climates.

Triple Wall Pipes

• Structure: Laminated exterior with corrugated middle for strength.
• Use: Budget-friendly; expands and contracts well.

HDPE and PVC Joint Bonding

• Issue: HDPE does not bond well with PVC using traditional solvents.
• Solution: Use specific HDPE glue which remains flexible.

General Recommendations

• Application-Specific: No universal solution for drainage; must consider climate and intended use.
• Education and Awareness: Importance of choosing the right materials for longevity and minimal maintenance.

Conclusion

• Maintenance: All systems require some level of maintenance; aim for minimal and easy upkeep.
• Quality Systems: Build using high-quality materials to ensure long-lasting solutions.

Call to Action

• Engagement: Encouragement to leave comments and ask questions for further educational content.
