A Complete Waterproofing Materials System for Every Structure
Whether it is a rooftop, a basement, a tunnel or a hydraulic structure, leakage is the most hidden and the most expensive defect a building can suffer. Tosun supplies a full line of waterproofing materials: SBS modified bitumen membrane, polypropylene (PP) waterproofing sheet, waterproof coatings, and premium polymer membranes for high-end projects — covering selection, supply and application support in one place. For the basic principles behind these systems, see the Waterproofing article. With Tosun, your waterproofing materials rest on field-proven designs and more than a decade of project experience.
In this article
SBS Modified Bitumen Membrane
Weather-resistant with excellent low-temperature flexibility, torch-applied, ideal for roofs, tunnels and bridge decks over large areas.
Waterproof Coatings
Polyurethane and polymer-cement systems that form a seamless film, perfect for bathrooms, exterior walls and complex detail repair.
Polypropylene (PP) Waterproofing Sheet
PP fiber bonded with polyethylene — eco-friendly, cost-effective and reliably lapped. Widely used in basements, tanks and damp-proof courses.
Premium Polymer Membranes (PVC/TPO)
Long service life with hot-air welded seams, engineered for premium buildings and critical infrastructure.

Frequently Asked Questions
What is the difference between waterproofing membranes and coatings?
Membranes form a continuous, high-strength layer over large areas, ideal for roofs and basements. Coatings cure into a seamless film, better suited for pipe penetrations, corners and complex details. The two are often combined to complement each other.
What is a polypropylene (PP) waterproofing sheet?
A PP sheet is a composite of polypropylene fiber and polyethylene film. It is eco-friendly, lightweight yet strong, and easy to install. Its outstanding value makes it a popular choice for basements, water tanks and damp-proof courses.
Which climates suit SBS modified bitumen membrane?
SBS-modified bitumen balances low-temperature flexibility with high-temperature stability, and works reliably from about -20°C to 100°C. It is a well-proven option for cold regions and areas with large temperature swings.
How do I choose the right waterproofing materials for my project?
Consider the substrate type, local climate, water pressure and the required design life. Send your project details to the Tosun engineering team and we will reply with a recommended system and a side-by-side quotation.
Are there minimum order quantities or lead times?
We support both project-based custom orders and regular restock orders. Standard membranes and coatings have stable lead times, and large projects can be delivered in batches to match the construction schedule.
