Sika recently announced that it has acquired American Hydrotech Inc. in the U.S. and its affiliate Hydrotech Membrane Corp. in Canada. Hydrotech manufactures liquid membranes and provides full-system roofing and waterproofing solutions. The acquisition reportedly strengthens Sika’s roofing and waterproofing portfolio while complementing the company’s sustainability focus. In 2020, the acquired company generated sales of CHF 83 million (approximately $90.2 million).

For more than 44 years, Hydrotech’s solutions have been specified by architects and design professionals. As more building rooftops are transformed into valuable leisure space, the company’s garden roof systems are reportedly growing rapidly. Hydrotech also brings a strong market position in the waterproofing of plaza decks and foundations. The company offers products containing post-consumer recycled material (e.g, membranes use 40% recycled materials).

With this acquisition, Sika reports that it will become the number-one supplier of green roofs in North America. In addition, Sika gains a new growth platform with the expanded offering of complete roofing and waterproofing systems. The two companies have a similar corporate culture with highly motivated people and a strong focus on sustainable, reliable, long-lasting solutions and customer relationships.

“With this acquisition, Sika establishes a leading position in the fast-growing application of green/garden roofing and waterproofing,” said Christoph Ganz, regional manager Americas. “This perfectly fits Sika’s sustainability focus, and strengthens our position in the big cities where green roofs continue to gain momentum. We are very excited to welcome the Hydrotech employees to the Sika family and look forward to continue developing the business together.”
