Innovative Waterproofing Solution at Newly Completed Woods Hole Ferry Terminal

Introducing the Revamped Woods Hole Ferry Terminal

In May 2026, the expanded ferry terminal in Woods Hole, Falmouth, Massachusetts, officially opened its doors after a decade-long planning phase. Supervised by Boston's BIA Studio, the project is a critical infrastructure upgrade for the local ferry services, which provide vital links to Oak Bluffs and Vineyard Haven on Martha's Vineyard. The terminal, set against the scenic backdrop of Cape Cod, represents a significant investment in the region's transportation capabilities, costing approximately $32 million.

The Need for Durability in a Marine Environment

The new terminal's construction came with unique challenges, primarily due to its waterfront location, which exposes it to a high level of chloride from seawater. To combat potential concrete degradation, the project's team opted for PENETRON ADMIX SB, a pioneering crystalline waterproofing admixture. This choice ensured that vital underground components of the building would maintain their integrity over time, even amidst the corrosive effects of saltwater.

Specifications of the Terminal

The project's scope included building a spacious 5,418-square-foot terminal along with associated facilities such as utility buildings, attendant booths, and bus berths. It also updated surrounding site utilities and implemented an advanced stormwater management system. One of the most significant innovations was using around 2,000 cubic yards of concrete enriched with PENETRON ADMIX SB, specifically formulated for the terminal's below-grade mat slabs and retaining walls. The concrete's 1-foot-thick (30cm) members were engineered to withstand the demanding marine conditions.

Richard Farmer, Eastern Region Sales Manager of Penetron USA, acknowledged the complex nature of this endeavor, stating that previous ferry structures could not meet the more rigorous construction standards necessitated by modern ferry infrastructure. The original facility was ultimately replaced to accommodate robust, pile-driven designs that were essential for enhanced structural integrity.

The Concrete Solution

PENETRON ADMIX SB works through a unique chemical reaction that forms insoluble crystals within the concrete matrix, sealing off any pores and micro-cracks and significantly reducing water permeability. This
