Can TPO membranes be used as root-resistant waterproofing membranes?
A
Yes, TPO waterproofing membranes have root-resistant properties. The membrane itself is dense, and the overlaps are hot-air welded, creating a continuous barrier. This physical structure provides effective resistance against root penetration, making TPO suitable for use in green roof systems.
What is the seam treatment method for TPO waterproofing membranes?
A
The seams of TPO waterproofing membranes are joined using hot-air welding. Specialized welding equipment blows hot air to melt the upper and lower surfaces of the overlapping membranes, allowing them to fuse together into a single, continuous layer.
What types of buildings are suitable for TPO single-ply roofing systems?
A
TPO single-ply roofing systems are commonly used on large-span steel structure roofs, such as those of industrial plants, commercial buildings (e.g., IKEA, Costco), as well as airport terminals and sports venues.
What are the features of our TPO single-ply roofing system?
A
The TPO single-ply roofing system offers excellent waterproofing performance. The membrane overlaps are joined using hot-air welding, ensuring a reliable and secure seal. In addition, using white TPO membranes helps reflect most of the solar radiation, which reduces indoor temperatures in summer and lowers the energy consumption of cooling systems.
What are the typical application scenarios for different types of TPO membranes?
A
· Reinforced TPO membranes are commonly used in single-ply roofing systems and are typically installed using mechanical fastening methods.
· Fleece-backed TPO membranes are usually bonded to the roofing substrate using adhesives in a fully adhered system.
· Homogeneous TPO membranes are typically used for detailing and treating intricate areas.
· Pre-applied TPO membranes are commonly used for basement slabs. The adhesive side of the membrane faces upward and is loosely laid over the concrete blinding layer. Reinforcement is then tied directly on top, followed by the casting of the slab concrete.
· Self-adhesive TPO membranes are often used in combination with waterproof coatings on basement walls and roof slabs.
