Moisture proofing and damp prevention by Gero Milieutechnieken.

Just like most people, concrete, stone, wood and metal do not like rain and damp. Thankfully, Gero Milieutechnieken protects these materials from mould, decay, corrosion and rust. For more than 40 years, we have made them hydrophobic and/or impregnated them with a broad selection of moisture-proofing agents, sealants and coatings, including Pro, Hydro and Wood-Sealers.

Specialised in the agents used to impregnate and/or make a range of materials hydrophobic.

Our high-quality impregnating agents, sealants and coatings have been employed for years by a number of regular customers within the government, and the industrial, construction and offshore sectors. Wood, metal and concrete treatments, moisture-proofing products for walls, facades and crawlspaces – we always have a solution to your problem. 

Our products and services significantly increase the lifespan of materials such as wood, concrete, iron and more. They also combat algae and moulds, significantly improving the indoor climate for both humans and animals.
