Newton NewSeal – Puncture-Resistant HDPE Root Barrier
Newton NewSeal is a high-performance HDPE root barrier designed to prevent root penetration and protect primary waterproofing membranes in green roofs and planters where intrusive root systems are present. Its impermeable High-Density Polyethylene (HDPE) composition ensures a robust, durable, and long-lasting barrier against root damage.
Lightweight and easy to install, Newton NewSeal provides excellent resistance to chemicals, biological elements, seawater, and fertilizers, making it suitable for both newly planted and existing trees and vegetation.
Key Benefits:
✅ Ultimate root protection – Prevents penetration and damage to waterproofing membranes
✅ Highly resistant – Withstands chemicals, biological agents, seawater, and fertilizers
✅ Lightweight yet durable – Easy to handle without compromising on strength
✅ Quick installation – Simple and efficient application process
✅ Exceptional puncture resistance – Designed to withstand pressure and root intrusion
Typical Applications:
✔ Root barrier for protecting waterproofing membranes in green roof systems
✔ Planter protection against intrusive root growth
✔ Suitable for both new and existing trees and plants
