4mm Copper‑core Sbs Root Resistant Waterproof Membrane

Advantages of 4mm Root‑penetration Resistant SBS Modified Bitumen Waterproof Membrane

1. Reliable root‑penetration resistance Adopted copper‑foil core or chemical root‑resistant formula, it effectively blocks piercing from plant roots and meets national standards for planting roofs, protecting waterproof system of green slabs.
2. Excellent SBS elasticity against substrate deformation and cracking Rubber‑like high elongation adapts to thermal expansion‑contraction and concrete shrinkage. Good crack‑bridging performance prevents waterproof layer from breaking under minor substrate cracks.
3. High mechanical strength, construction‑damage resistant and walkable for maintenance Polyester mat reinforcement provides high tensile, tear and nail‑shank tearing strength. Resists puncture from gravel and steel bars during construction, suitable for walk‑on green roof inspection.
4. Integrated hot‑melt welding reduces water‑channeling risk Hot‑melt construction fuses lap seams into monolithic waterproof structure. Sand‑surfaced variant supports direct exposed application with good UV resistance.
5. Good bitumen‑material compatibility for composite waterproof system Perfectly compatible with non‑curing rubber‑bitumen coating. Composite system of non‑curing coating plus root‑resistant SBS solves typical water‑channeling leakage problem of planting slabs.
6. Resist water and soil corrosion for long buried‑service life Stable performance under long‑term soil‑covered and water‑immersed conditions, resisting underground water and salt corrosion. Slow aging under enclosed buried environment.
7. Mature construction technology for new and renovation projects Applicable for new green roof slabs and old green‑roof renovation. Mature reinforcement solutions for pile heads, post‑pouring belts and drain‑board surrounding areas.
