汉堡地下室漏水解决专家 | KellerRetter Hamburg

We are a Hamburg-based company that specializes in professionally solving basement leaks. Thanks to technological advances and unlike traditional methods, we use advanced materials based on nanotechnology to permanently seal leaks and give you back a dry and clean basement.

This innovative method cleverly solves the problem of negative pressure when water penetrates into basements. It offers a long-term effect, can be carried out at any time of the year and does not require digging up the external walls of the basement. Clean, fast, efficient and cost-saving – for a sustainable result that impresses.

A spacious unfinished basement with exposed wooden beams on the ceiling and concrete floors. The walls are partially covered with wooden framing and plastic sheets. There is a door on the right side and a small window at the end of the room, providing some natural light. Pipes and ductwork are visible along the ceiling.

An entrance to a basement with tiled walls illuminated by a light. A window reflecting outdoor foliage and a sign saying 'Additions Goods' is visible. The scene includes a mix of natural and architectural elements, with plants lining a brick pathway.

about Us

Basement waterproofing projects

Dark, textured concrete wall with streaks and stains from water erosion, creating an abstract pattern. A stream of water flows smoothly at the bottom with a long exposure effect, creating a soft, blurred motion.

A concrete structure runs along the left side with visible metal railings. Below the structure, a layer of dark, polluted water is partially contained by a floating boom. The surface of the water reflects parts of the surroundings, suggesting an industrial environment.

A dimly lit basement or underground passageway with exposed concrete walls and ceiling, featuring large pipes running along the left side and overhead. The floor is cluttered with various objects including an electrical outlet, plywood, and some bags. The lighting is sparse, casting shadows and creating a somewhat eerie and abandoned atmosphere.

A concrete and cinder block basement room with two vertical pipes, one metallic and the other dark in color. The area is dimly lit, casting shadows on the walls, and there's a red box affixed to the wall.

Anyway, the leaky, heavily contaminated basement...

Successful projects where we solved leakage problems using nanomaterials.

We can solve the problem quickly and thoroughly and keep the construction process clean and tidy without disrupting the residents' everyday lives as little as possible.
