What’s expiring, and when
Two Weber Saint‑Gobain Sweden AB declarations are set to lapse in February 2027. They cover flowing concrete underlayments used for casting and floor prep in the 03 54 00 Cast Underlayment category.
- weber lättflytande finbetong, valid to 2027‑02‑14
- weber lättflytande grovbetong, valid to 2027‑02‑14
Both sit in the same family of cementitious, pumpable mixes commonly specified ahead of resilient, tile, or polished finishes.
Are replacements already live
As of June 20, 2026, no like‑for‑like renewal EPDs for these exact SKUs are visible. Weber does have other current declarations in adjacent mixes, including a finbetong variant positioned as “REKO” that remains valid into 2029, but it is a different product and not a direct substitute by name or declared scope.

Likely detours specifiers will take
If a February gap appears, teams will lean on comparable self‑leveling or repair underlayments with active EPDs. Examples that are current today include:
- MAPEI Ultraplan 1 Plus self‑leveling underlayment, valid to 2028‑07‑23
- MAPEI Ultraplan Easy self‑leveling underlayment, valid to 2028‑07‑23
- ARDEX K 22 F calcium‑sulfate underlayment, valid to 2029‑02‑16
These live options will often clear the EPD checkbox for flooring packages while Weber’s SKUs await refresh.
Why a few months matters commercially
On many bids, a missing or expired declaration pushes buyers to use conservative default values in carbon tallies. That can nudge a product out of contention even when performance is strong, because the penalty lands at the worst possible time in procurement. Staying current is less about marketing and more about avoiding avoidable friction when sepcifiers finalize schedules.
Renewal timing and the PCR lens
Floor underlayments are typically declared to EN 15804 with a program operator that supports Nordic publication. When an EPD is due for renewal, check which Part B or product guidance peers are using, then align so your numbers remain comparable in the tools design teams rely on. Five‑year validity windows mean data collection should kick off well before year four if you want a calm handoff rather than a cliff.
How to keep the spec door open
Pull utility and throughput data for the most recent stable 12‑month period, confirm plant boundaries, and verify mix designs against current production. Decide early which operator you will publish with in the target market, since that choice sets templates and reviewer expectations. Map any recipe changes that could improve impacts so the renewal is not just on time, it is better on the scoreboard.
Bottom line for project teams
If Weber publishes replacements before February 2027, spec continuity should hold with no change orders. If not, expect substitutions toward current EPDs in similar self‑levelling families from the brands above. Either way, early planning beats last‑week fire drills every single time.
