Developed by UKS Yapı, UKS Bituminous Membrane Systems provide reliable waterproofing protection for building components exposed to water, from foundations to roofs. Available in both APP-modified and SBS-modified versions, these membranes offer effective solutions for a wide range of climate conditions and project requirements.
Waterproofing plays a critical role in extending a building's service life and structural durability. Choosing the right membrane for foundations, basements, terraces, and roofs significantly reduces the risk of moisture intrusion, water leakage, and long-term structural damage.
Bituminous membranes are asphalt-based waterproofing sheets manufactured in roll form and typically installed using a torch-on application method. UKS offers both plastomeric (APP) and elastomeric (SBS) modified membranes to meet the demands of hot and cold climate conditions.
With excellent flexibility, durability, and long service life, these membranes are available with different reinforcement types and surface finishes to suit a wide variety of waterproofing applications.
UKS Bituminous Membranes are suitable for:
The concrete substrate should be clean, dry, and level.
Apply a bitumen-based primer to improve membrane adhesion.
The membrane rolls are heated using a propane torch and bonded directly to the substrate.
Adjacent sheets should overlap by at least 10 cm to create a continuous waterproof barrier.
In areas exposed to sunlight, mineral-finished membranes or a protective concrete layer should be used.
APP and SBS modified membranes create a highly effective barrier against water penetration.
SBS-modified membranes retain their elasticity even at low temperatures, reducing the risk of cracking.
APP-modified membranes provide outstanding performance in areas exposed to prolonged sunlight and high temperatures.
Standard torch-on installation techniques allow for fast, reliable, and efficient application.
Various thicknesses, reinforcement materials, and surface finishes are available to meet different project requirements.
For optimal performance:
When properly installed, they typically provide a service life of 25–30 years.
APP-modified membranes are generally recommended for hot and sunny climates, while SBS-modified membranes are better suited to colder environments because of their superior flexibility.
A two-layer waterproofing system is commonly recommended, although the final specification depends on the project's design requirements.
UKS membranes are available in thicknesses ranging from 1.5 mm to 4 mm.
Polyester-reinforced membranes provide superior mechanical strength, while glass fiber-reinforced membranes are often preferred for more economical waterproofing solutions.
UKS Bituminous Membrane Systems offer dependable waterproofing performance, long service life, and excellent durability for residential, commercial, industrial, and infrastructure projects. By selecting the appropriate membrane type and ensuring professional installation, buildings can be effectively protected against water damage for decades.
