Green Roof Waterproofing

Green roofs benefit the environment while creating attractive spaces for people and wildlife. They can also help protect the roof waterproofing system from thermal and mechanical stresses, contributing to the long-term performance of the roof.

SURE-WELD Referenzobjekt Industriebau

Industrial Construction

Industrial and commercial roofs provide protection for people, buildings, production facilities, and valuable assets. These applications demand solutions that are sustainable, reliably perform over the long term, and remain economically efficient.

Terrassentürabdichtung mit Liquiseal

Balcony and Terrace Waterproofing

Balconies, terraces and access walkways are integral elements of modern buildings. Yet their long-term protection against moisture ingress is often underestimated. We show how professional waterproofing solutions can ensure durable, reliable performance and lasting protection for these heavily exposed areas.

Garagendachabdichtung mit EPDM

Garage Roof Waterproofing

Garages and carports may be secondary buildings, but they still require reliable year-round protection. A high-performance roof waterproofing system provides long-lasting protection and can be installed on virtually all common construction substrates.

Unwetter Flachdach

Flat Roof Drainage

Standing water on a flat roof is often unavoidable, even on roofs with falls of up to 5%. That is why, alongside a high-performance waterproofing system, an effective drainage solution is essential for the long-term performance and durability of the roof.

Sustainable Construction

Flat roofs can play a key role in sustainable building design, whether as green roofs, platforms for photovoltaic and solar systems, or as areas for future vertical extensions. High-performance and sustainable waterproofing materials are essential to support these multifunctional uses and ensure long-term building performance.

Fall Protection for Flat Roofs

At CARLISLE®, we do not just make flat roofs watertight, we make them safer places to access and work on. Our fall protection systems provide reliable protection for both collective and individual safety, helping to ensure safe working conditions throughout the entire life cycle of the roof.

Versatility on Flat Roofs

Whether as functional space, usable space, or living environment, flat roofs offer enormous creative potential.

Extensive and intensive green roof systems play an increasingly important role in compensating for sealed urban surfaces while supporting biodiversity and sustainable stormwater management. Flat roofs also provide an ideal platform for urban gardening, photovoltaic systems, and solar installations.

Where structural conditions permit, existing buildings can even be extended vertically above the current roof level. This creates valuable additional living space, particularly in urban areas, without the need to seal further land.

With RESITRIX®, HERTALAN®, ALUTRIX®, SURE-WELD®, LIQUISEAL®, and SAFETY SYSTEM, we offer innovative, durable solutions that combine design flexibility with proven performance and long-term reliability.
