Seamless & Durable Waterproofing

We sustainably protect your building structure from penetrating moisture. With state-of-the-art liquid plastic systems and crack-bridging elastomer sheets, we create an absolutely waterproof, frost-resistant protective layer – even on complex joints.

Premium Coverings & Liquid Plastic Coatings

Give your balcony an exclusive look: We lay elegant ceramic tiles on pedestal supports, durable wood/WPC decking, or a high-grade liquid plastic coating that is particularly easy to clean and durable.

Professional Concrete Restoration

Safety comes first. Before waterproofing, we professionally repair cracks, hollow spaces, and spalled concrete. Corroded reinforcement steel is permanently sealed to ensure the load-bearing capacity of your balcony for decades.

Frequently Asked Questions

Questions about Balcony & Terrace Renovation

Typical signs include damp spots on the underside of the support slab, cracks in tiles/joints, flaking concrete, salt efflorescence (white borders), or moisture damage on the adjacent house wall.

We offer a wide selection: from durable stone slabs on pedestals or gravel beds to WPC decking, and seamless liquid plastic systems that are completely crack-bridging and barrier-free.

No, for the professional installation of the waterproofing and wear layers (especially with liquid plastic systems), the concrete substrate must be absolutely dry and the weather frost-free. In case of unstable weather, we protect the work area with special tent systems if necessary.

Depending on the size and desired covering system, execution usually takes between 3 and 5 working days. With modern liquid plastic systems, the surfaces are often fully walkable and rainproof after just a few hours.
