Sika moves forward with Upper Deerfield mortar production site

A 250,000-square-foot mortar plant is now running on Route 77 in Upper Deerfield, turning a two-year planning process into one of Cumberland County’s most concrete industrial investments. Sika said the facility will support up to 50 jobs in Cumberland County and serve customers across the Northeast region of the United States and surrounding markets.

The plant was fully operational by April 10, 2026, when Sika marked the opening of its Upper Deerfield site. The company described the project as its Northeast Anchor site, and said it strengthens its supply chain and manufacturing footprint in the region. The plant produces high-performance cementitious grouts, self-leveling mortars and shotcrete mixes, and Sika said it uses advanced digitalization and automation technologies.

For Upper Deerfield, the decision is more than a corporate announcement. It is a large industrial facility at 1262 Highway 77, on Block 1201, Lots 1 and 3, that adds manufacturing activity to a part of Cumberland County where land use, trucking access and industrial tax base matter to township leaders and nearby businesses. Sika’s move from site review to full operation gives the township a new production asset with longer-term implications for employment and local spending.

Township records show the project was already moving through the Upper Deerfield Township Planning Board in June 2023. By November 2023, township agendas identified Sika’s proposal as a manufacturing facility at 1262 Highway 77, where the company planned to blend and combine components into building material products. In June 2024, the amended site plan had already changed, reducing the building’s size and height and eliminating a training center.

Sika broke ground on the plant in July 2024 and said at the time that it expected the facility to be operating in late 2025. That timeline slipped into spring 2026, but the company’s latest opening put the project firmly into production. Jim Walther, Sika’s U.S. president, also said the company planned additional expansions at the Upper Deerfield site over the next several years.

The opening gives Upper Deerfield a working example of industrial investment that moved from board review to construction to production. What comes next will be measured in jobs, shipping activity and the pace of future expansion at a site now tied to Sika’s Northeast strategy.
