Axter waterproofing portfolio and EPD coverage snapshot

Who Axter is, in one minute

Axter is a French waterproofing specialist with international reach, active in roofing and civil works. The core offer centers on three families of membranes for flat and low‑slope roofs, supported by detailing components and training. Their site also highlights eco‑oriented solutions like cool roofs, photovoltaics, and vegetated systems, all grouped under “Nos produits écoresponsables” on the homepage (axter.eu).

What they sell, at a glance

Bituminous systems are the backbone, including HYRENE and FORCE lines for multi‑layer and single‑layer designs. Synthetic membranes appear under HYPERFLEX PVC, with reflective white options for heat islands. Liquid‑applied systems such as STARCOAT PRO cover complex detailing and podiums. Counting variants by thickness, reinforcement, surface finish, and installation method, the portfolio likely runs to hundreds of SKUs across a handful of main categories.

EPDs and FDES, separated by market rules

In France, specifiers rely on FDES, the French format of an EPD with added health data, verified to EN 15804 and ISO 14025 and typically valid for 5 years (INIES, 2025). Axter lists downloadable FDES sets covering bicouche, monocouche, vapor barriers, and PVC membranes 1.2 to 2.0 mm on its website, which gives French projects the documentation they expect (Axter FDES page, 2026).

Outside France, conventional EN 15804 EPDs matter most. Axter’s UK arm has published product‑specific EPDs for its hot‑melt structural waterproofing systems, including Wilotekt‑Plus, published June 29, 2025 and valid to June 29, 2030 (EPD Hub, 2025). That helps on UK and EU projects where third‑party verified 15804 EPDs are requested in tender prerequisites.

Coverage, strengths and likely gaps

Coverage looks solid where Axter sells most: multi‑layer and single‑layer bitumen and core PVC thicknesses in France via FDES, and hot‑melt systems in the UK with product‑specific EPDs. We did not find the same depth of declarations for ancillary materials like primers, adhesives, and certain accessories, which often appear on submittal lists. These small items can still trip up a WBLCA tally. Liquid systems may also be spottier than membranes in project libraries. If that is the case in your catalog, close it fast so a competitor’s fully documented system is not the easy swap.

A best‑seller without an EPD, and the spec risk

If a popular liquid‑applied deck or podium assembly lacks an EPD, project teams will reach for a comparable system that does. Competitors routinely publish bitumen and single‑ply EPDs across Europe, for example Soprema on the Environdec program in 2024 and 2025, including SBS membranes such as SOPRALENE series (Environdec, 2024–2025). EPDM players are catching up too, with VM Building Solutions announcing RESITRIX FDES availability for France (VM Building Solutions, 2025). Where a declaration is missing, specifiers often have to apply conservative default factors, which makes the un‑declared option harder to justify on carbon‑scored projects.

Who Axter fights for the spec

You will often see Soprema, Sika Sarnafil, Bauder, BMI Icopal or Siplast, Renolit Alkorplan, Elevate (Firestone), and VM Building Solutions in the same bid stack. Some compete like‑for‑like on bitumen, others on PVC, TPO, EPDM, or liquid. The common thread is transparent, product‑specific EPDs that slot neatly into WBLCA and LEED v5 material credits.

Plays that level up specability fast

Pick two to four high‑volume systems and publish product‑specific EPDs or FDES, then expand by variants. Bundle the declaration work so membranes, primers, adhesives, and key accessories land in one coherent set. Map France with FDES and cross‑publish EN 15804 EPDs for export markets where needed. Keep renewal dates on a live calendar so nothing lapses right before a strategic bid. The heavy lift is data collection inside the factory, so choose an LCA partner who makes that enviromental data pull painless for production, R&D, and quality teams.

Why it pays off this year

More public and private owners now request verified declarations during prequal or at tender, and LEED v5 keeps EPDs front and center. When your product has a current, product‑specific declaration, the design team avoids penalties from defaults and is more likely to keep your spec intact rather than substitute. One medium project can repay the credential effort many times over.

Bottom line for Axter watchers

Axter’s French catalog shows broad FDES coverage for core membranes, and the UK team already fields product‑specific 15804 EPDs for hot‑melt systems. Extend that rigor to liquids and auxiliaries, mirror it across export ranges, and the brand becomes the easy pick on carbon‑aware jobs.
