Sika has acquired United Gilsonite Laboratories (UGL), a manufacturer of products for consumer and DIY waterproofing applications. According to Sika, the acquired business is a complement to its high value-added systems for concrete and masonry waterproofing and refurbishment. In 2021, UGL generated sales of CHF 65 million (approximately $66.5 million).

With headquarters and production in Scranton, Pa., as well as two additional production sites in Illinois and Mississippi, UGL supplies its products to customers in every region of the U.S. For Sika, the acquisition will increase its presence with major retailers and other building material stores by widening its offering and opening up cross-selling opportunities.

Sika reports that, in the large U.S. residential housing segment, demand for watertight basements is anticipated to grow at above-average rates in the years to come. In commercial construction, the need for watertight basements to maximize building utility and protect valuable assets and investments continues to grow. With the combined offerings of the two companies, Sika can take advantage of the growth trends in both the residential and commercial construction segments.

“UGL is a perfect complement to Sika’s current portfolio,” said Christoph Ganz, Sika’s regional manager for the Americas. “The UGL brands are well recognized in the USA, and their consumer and DIY waterproofing solutions allow Sika to extend its business in the USA construction industry. We warmly welcome all the UGL employees to our Sika team.”
