Bituminous Waterproof Membrane Manufacturer & Supplier

Bituminous waterproof membranes are one of the most widely used waterproofing materials in modern construction. Made from modified bitumen combined with reinforcement layers such as polyester or fiberglass, these membranes provide excellent protection against water penetration, weather exposure, and structural movement.

Oseguard bituminous waterproof membranes are designed to meet various project requirements, offering different reinforcement structures, surface finishes, and installation methods to ensure long-term waterproof performance.

What Is Bituminous Waterproof Membrane?

Bituminous waterproof membrane is a flexible waterproofing material made from bitumen (asphalt) combined with reinforcement materials such as polyester felt or fiberglass mat. It is widely used in construction to create a durable, waterproof barrier that prevents water from penetrating building structures.
Because of its excellent waterproofing performance, durability, and cost-effectiveness, bituminous membranes are one of the most commonly used waterproofing materials in roofing, basements, foundations, and infrastructure projects.

Structure of Bituminous Waterproof Membrane

1. Surface Layer

Mineral granules
Sand surface
PE film
This layer protects the membrane from UV radiation and mechanical damage.

2. Modified Bitumen Layer

The core waterproofing layer is made from SBS or APP modified bitumen, providing excellent water resistance and durability.

3. Reinforcement Layer

Common reinforcement materials include:
Polyester felt
Fiberglass mat
Composite reinforcement
These materials improve tensile strength and dimensional stability.

4. Bottom Layer

Usually covered with PE film or sand, designed for installation using torch application or adhesive bonding.

Types of Bituminous Waterproof Membrane

According to the type of Modified Bitumen Membrane


APP (Atactic Polypropylene) modified membranes offer excellent heat resistance and UV stability	SBS (Styrene-Butadiene-Styrene) modified membranes are known for their rubber-like flexibility and crack resistance

Modified bitumen membranes according to the type of reinforcement structure


Composite reinforced membranes combine multiple reinforcement materials, typically fiberglass and polyester, to improve both dimensional stability and tensile strength	Fiberglass reinforced membranes use fiberglass mats as the reinforcement layer, providing excellent dimensional stability and resistance to deformation	Polyester reinforced membranes use polyester felt as the reinforcement layer, which provides excellent flexibility and crack resistance

Modified bitumen membranes according to the installation method


Torch-applied membranes are installed using heat welding with a gas torch, which melts the bitumen layer and bonds it to the substrate	Self-adhesive membranes have a pre-applied adhesive layer, allowing installation without open flame heating

Advantages of Bituminous Waterproof Membranes

Bituminous waterproofing systems remain a preferred choice in the construction industry because of several important benefits.

Excellent Waterproof Performance

Bitumen forms a continuous waterproof barrier that effectively prevents water infiltration.

Strong Durability

With reinforcement layers such as polyester or fiberglass, these membranes offer long service life even under harsh environmental conditions.

High Adaptability

Different membrane types allow use in roofing, basements, tunnels, and infrastructure projects.

Cost-Effective Solution

Compared with many polymer waterproofing systems, bituminous membranes provide excellent performance at a competitive cost.

Applications of Bituminous waterproof membrane

Bituminous Waterproof Membrane is widely used in:

Commercial Roof Waterproofing

Flat Roof Waterproofing

Basement Waterproofing System

How to Choose the Right Bituminous Waterproof Membrane?

Selecting the appropriate waterproof membrane depends on several project factors.

Climate Conditions

Hot climates: APP modified membranes perform better.

Cold climates: SBS modified membranes provide better flexibility.

Structural Movement

Buildings that experience structural movement require membranes with high elasticity, such as polyester-reinforced SBS membranes.

Installation Method

Projects may choose between:

Torch applied systems

Self-adhesive systems

depending on construction conditions.

Exposure Conditions

For exposed roofing systems, mineral surfaced membranes are typically used as the top layer.
