Watson Bowman Acme: EPD readiness check
Watson Bowman Acme is a go‑to name for civil and transportation expansion joint systems. The portfolio is deep, the brand is respected, yet product‑specific EPDs are not easy to spot. If your team sells into LEED‑driven buildings or public owners that prefer declarations, that visibility gap can quietly cost specs you never hear about.
Who they are and where they play
Watson Bowman Acme (WBA) manufactures Wabo‑branded expansion joint systems primarily for bridges, tunnels, and heavy‑duty infrastructure. In May 2023, the company joined Sika, whose 2024 sales reached CHF 11.76 billion, signaling significant backing and scale (WBA About Us, 2025). citeturn0search3
What they sell, in plain English
Think movement and watertightness. Flagship lines include strip‑seal and modular finger joints for highways, molded segmental systems like Wabo Flex, silicone and foam seals such as Wabo SPS and Evazote, joint headers and repair materials like WaboCrete II and SurfaceMend, plus accessories that manage water with flexible gutters. These are the practical staples that keep decks riding smooth and joints sealed when the real world throws traffic, freeze‑thaw, and seismic events at a structure. citeturn0search0turn0search2turn0search5turn1search11
For commercial building interiors and parking or stadium covers, WBA points buyers to its sister brand Emseal, now under the same Sika umbrella, which centralizes those SKUs for architects and GCs. That split helps each brand stay focused on the details of its core applications. citeturn0search1turn2search2
How broad is the catalog
Across bridge and tunnel needs, parking structures, and specialized sealing, WBA spans several product categories with what looks like dozens of individual SKUs. Exact counts fluctuate with model sizes and options, so treat it as a living catalog rather than a fixed line card.

EPD visibility today
We could not locate public, product‑specific EPDs for WBA‑branded expansion joint systems as of December 19, 2025. If they exist behind the scenes, they are hard to find for specifiers. That matters because product‑specific Type III EPDs with external verification count as 1.5 products toward LEED’s materials credit tally, which is a quiet tie‑breaker on many jobs (USGBC Credit Library, 2024). LEED v5 was ratified on March 28, 2025, and continues to emphasize credible disclosure, so being visible helps the sales story (USGBC, 2025). citeturn8search0turn4search0
Why that gap costs real bids
LEED’s EPD tally asks most projects to show at least 20 qualifying products from five manufacturers, with 40 for exemplary performance. A product‑specific EPD that is easy to download can move a Wabo SKU from “maybe” to “in the submittal” without a price fight (USGBC Credit Library, 2024). Owners outside buildings are moving too. Caltrans now requires EPD submittals for asphalt and concrete on bids with openings from February 1, 2025, a sign of how infrastructure procurement is normalizing declarations even if joints are not yet listed materials (Caltrans, 2025). citeturn8search0turn6search6
If coverage is thin, where to start
A fast first win is a high‑volume, simpler formulation that shows up on many decks and rehab jobs. Examples include Wabo StripSeal or a preformed silicone or foam seal. Those see repeat use, have relatively tight BOMs, and unlock repeatable carbon accounting. In parallel, pick one complex hero, like a molded segmental joint, to demonstrate leadership. If a dedicated PCR for expansion joints is not available, a seasoned LCA partner maps to accepted construction product rules and operator expectations, then validates under a reputable program. The right partner shoulders the data chase inside your plants so engineers and PMs dont have to.
Competitive context WBA meets most often
On bridges and highways, expect D.S. Brown and regional fabricators. For parking and building interiors, Emseal, Construction Specialties, Balco, MM Systems, and Nystrom show up frequently. Not every rival is publishing EPDs for expansion joints, yet some adjacent lines are already visible. Example, Construction Specialties lists multiple current, third‑party verified EPDs for portions of its portfolio such as architectural louvers, which boosts spec familiarity with their brand on LEED projects (NSF Listings, 2025). There are also joint‑sealing tapes with EPDs on the market, proving the category is declarable when a manufacturer leans in (EPD International, 2025). citeturn7search0turn3search2
What good looks like operationally
- Pick a recent 12‑month reference year and lock the plant data plan early (utilities, materials, scrap, transport, volumes).
- Publish product‑specific, externally verified EPDs first for the SKUs that drive most quotes. This gives specifiers confidence and helps project teams finish BPDO tallies faster (USGBC Credit Library, 2024). citeturn8search1
Sustainability signals already in place
WBA highlights packaging design that prioritizes recyclable materials and clear labeling. It is a small but positive indicator to owners and GCs who scan for credible sustainability effort. See their note on packaging here: WBA packaging sustainability.
Where this leaves product teams
WBA is a category leader in expansion control for civil work. Turning that technical lead into spec certainty on LEED‑chasing buildings, stadiums, and public jobs requires EPDs that are easy to find, product‑specific, and third‑party verified. Start with the repeat sellers, keep the documentation clean, and let the declarations quietly earn their keep in submittals and prebid Q&A.
Frequently Asked Questions
Does LEED v5 still reward product‑specific EPDs and why does that matter for WBA?
Yes. LEED v5, ratified March 28, 2025, maintains the disclosure scaffold while shifting more weight to decarbonization. In practice, product‑specific Type III EPDs remain useful because teams still assemble BPDO product counts and favor brands that make documentation easy to source (USGBC, 2025). citeturn4search0
If there is no expansion‑joint‑specific PCR, can we still publish?
Often yes. Many sealing and construction product families fall under general Part A rules plus relevant Part B PCRs. Experienced LCA partners map the product to acceptable rules and program operators, then verify to ISO 14025 and EN 15804 or ISO 21930.
What is a credible first product to declare from WBA’s catalog?
A high‑volume line with a tight bill of materials, such as a preformed silicone or foam seal or the widely used Wabo StripSeal header plus seal kit. These SKUs show up often in bids and deliver repeatable data collection.
Which competitors are most likely to face WBA in specs?
For bridges and highways, D.S. Brown and regional fabricators. For parking and building interiors, Emseal, Construction Specialties, Balco, MM Systems, and Nystrom. Some adjacent product lines from these brands already have verified EPDs, which familiarizes specifiers with them on LEED projects (NSF Listings, 2025). citeturn7search0
Is there proof that joint‑sealing products can publish EPDs at all?
Yes. EPD International lists joint tape and sealing systems with valid EPDs, which shows the pathway for similar elastomeric profiles (EPD International, 2025). citeturn3search2
