Polyurethane Liquid Membranes

POLYURETHANE LIQUID WITH MEMBRANE
HIGH PERFORMANCE WATERPROOFING!

Polyurethane Liquid Membranes

Polyurethane liquid waterproofing membranes are high-performance insulation materials formulated with polyurethane resins and special additives and applied in liquid form. After application, they cure to form a seamless, flexible and completely waterproof layer. With its jointless and holistic structure, it provides maximum sealing and long-lasting insulation on building surfaces.

These systems can be easily applied on primers on concrete, wood, metal and similar surfaces. Thanks to its elastomeric structure, it adapts to surface movements and does not crack. In addition, it creates integrity with the surface thanks to its high adhesion strength.

Polyurethane Membrane Types

Aromatic Polyurethanes
– UV resistance is low.
– Used in closed areas that are not exposed to direct sunlight.
– It is preferred in cost-oriented projects due to its economic nature.

Aliphatic Polyurethanes
– Provides high UV resistance and color stability.
– Does not yellow on surfaces exposed to the sun.
– It is used as a final coat on terraces, roofs and open surfaces.

Hybrid Systems
– It is modified with polyurethane and different resins (e.g. polyaspartic).
– Provides faster curing.
– Chemical and UV resistance is increased.

Application Features and Advantages

– Jointless structure: Provides jointless, homogeneous coating.
– High adherence: It adheres perfectly to the surface with a suitable primer.
– Flexibility: It adapts to thermal expansion and contraction with its elastomeric structure.
– Durability: It is resistant to UV rays, water, chemicals and temperature differences.
– Ease of application: It can be applied with a brush, roller or air-assisted spray gun.

Sempoly Construction Chemicals As, we offer a wide range of reliable, long-lasting and high-performance product solutions that the construction sector needs. The product groups we develop are complementary to both surface preparation and coating and insulation systems. Each of our systems formulated in accordance with international quality standards; provides maximum performance in many application areas such as floor covering, waterproofing, repair and maintenance.

Linings:
Our polyurethane and epoxy based primers, developed to establish a strong bond between the surface and the coating, increase adhesion strength and ensure system integrity. With advantages such as high moisture tolerance, chemical resistance and fast curing, alternatives suitable for every surface type are offered.

Epoxy Floor Coatings:
Epoxy floor coatings, which are a perfect solution for industrial and commercial areas, stand out in terms of chemical resistance, abrasion resistance and hygiene requirements. They offer special floor solutions for each project with different thickness and color options.

Polyurethane Liquid Membranes:
Polyurethane liquid membranes, which offer jointless and seamless solutions in waterproofing, have crack-bridging properties thanks to their elastic structure. They provide long-lasting waterproofing in interior and exterior spaces with their aliphatic and aromatic options.

Polyurea Coatings:
Our polyurea systems, applied with hot spray technology and cured within seconds, show superior resistance to heavy traffic loads, chemicals and UV rays. It is used safely in terraces, parking lots, industrial floors and infrastructure projects.

Injection Resins:
Polyurethane and epoxy based injection systems offer effective solutions for repairing concrete cracks, stopping water leaks and ensuring structural integrity. They provide successful results even under difficult conditions with their low viscosity and high expansion types.

Repair Mortars and Complementary Materials:
Epoxy grouts, joint fillers, surface adhesives and system additives developed for the protection and repair of building systems support the application process. They provide permanent performance by working in full harmony with the system.

Each product line of Sempoly is developed to provide safe, durable and functional solutions for application professionals and engineers. All our systems are tested against harsh climatic conditions and heavy usage scenarios.
