Terrazzo flooring is a building material: chips of marble, granite, glass or another aggregate set in a binder, then ground and polished. The word is also used for speckled patterns printed on laminate, vinyl and plastic; this profile is only about the building material. A resinous-floor PCR, as quoted in one EPD, classifies terrazzo as aggregate in a binder matrix of Portland cement mortar, epoxy resin, polyester resin or vinyl ester resin.[12]
We use EPDs and data sheets from eight makers, a US government guide specification and two standards catalogue entries. Cement-bound products are declared against EN 13748-1 or EN 13813 classes and epoxy systems against test methods named in each sheet, so the two binders sit in separate tables.[1][2][4][5][7][8][9][10][11] For recycled aggregate see recycled glass and the Recycled guide; for cement and its carbon see low-carbon concrete; the Earth-based guide groups mineral materials.
What is terrazzo flooring, and how do cement-bound and resin-bound systems differ?
Precast cement terrazzo
EN 13748-1 specifies materials, properties and test methods for unreinforced cement-bound terrazzo tiles that are factory made, sold ready to be placed and intended for internal use. BSI lists BS EN 13748-1:2004+A1:2005 as current, published 31 October 2018 (we read the catalogue page, not the standard).[1] Grandinetti describes its tiles as made of marble granules or chips, mineral powders, cement, water and natural pigments, with solid-colour double-layer tiles typically pressed on a rotary press, in pre-polished or matte finishes (matte to be polished on site).[4] EUVAL and Agglotech instead cast large blocks, season them for 28 days or more, and cut slabs.[5][6] Agglotech's EPD says Portland cement is added as the binding material, "avoiding the use of resins", and also that the slabs are treated with a resin to fill imperfections and polished again to remove the excess; its composition table lists no resin and it gives no resin quantity. EUVAL's EPD says its terrazzo is made without any resin. Reading Agglotech's resin as a filling treatment of the slab surface rather than the binder is our interpretation of those two statements.[6][5]
Poured cement terrazzo
The US guide specification UFGS 09 66 13 (USACE, NAVFAC, AFCEC; August 2016, change 2 of November 2018) covers Portland cement terrazzo bonded to a concrete subfloor. Its topping is one 43 kg bag of cement per 91 kg of marble chips with about 20 L of water, over an underbed of one part cement to 4 or 4.5 parts sand; its note gives a normal total thickness of 45 mm, a 13 mm topping on a 32 mm underbed.[3] It is a public-sector template for US practice, not a product document. weber's EPD describes another route: a factory-blended, self-compacting product applied at 8 to 60 mm, with cement at 15 to 20 % and slag at 10 to 15 % by weight, which it says can be blended with aggregates such as marble, quartz or granite.[7]
Epoxy terrazzo
Sika's Canadian data sheet (March 2022) describes Sikafloor Terrazzo as a two-component, thin-set epoxy matrix for 6 to 9 mm, combined with aggregates, and says the applicator must run project-specific mix-design mock-ups.[8] Sika's Gulf sheet (October 2024) gives Sikafloor Terrazzo SA a body coat of about 25 kg/m² for 10 mm final thickness, with aggregates supplied by the applicator.[9] Flowcrete Polska describes Mondéco Mirrazzo as a seamless epoxy finish about 8 mm thick, polished by grinding.[10] Key Resin's EPD describes a trowel-applied epoxy at ¼ to ⅜ inch, ground and polished; aggregates and fillers are bought by the installing contractor, so the EPD counts them in installation (A5), not in its production-stage (A1–A3) figures.[11] The Terroxy RLF EPD assesses five resinous layers and two aggregate layers; it calls the primer and matrix necessary and the moisture-vapour treatment, fill and iso-crack membrane optional but recommended, the first two being needed where the slab is too humid or uneven. It states up to 22 % bio-based content without naming the basis.[12] We read no data sheet for polyester or vinyl ester terrazzo.
What aggregates do the documents name, and what do they say about recycled content?
Cement-bound products name marble (Grandinetti, EUVAL, Agglotech), and marble, quartz or granite (weber).[4][5][6][7] The epoxy sheets name a wider range: marble, granite, coloured or recycled glass, mirror particles, plastic chips and metal fragments (Sika), marble with coloured glass mirror particles (Flowcrete), and marble, coloured glass or granite (Key).[8][9][10][11]
The documents describe recycled content in different terms. Agglotech's EPD says its marble grit comes from marble fragments and quarry waste generated in block production, yet its resource-use tables declare 0 kg of secondary material.[6] EUVAL's EPD describes a high pre-consumer recycled content, with no percentage, and declares 28.8 kg of secondary material for the 2 cm slab (52 kg/m²) without naming the input; its 3 and 4 cm tables print 43.1 and 31.4 kg, which do not scale with thickness, so we use only the 2 cm figure.[5] Grandinetti declares 0 % post-consumer recycled material by mass but 10.7 kg of secondary material per m², again without naming the input; weber also declares 0 % post-consumer recycled material by weight.[4][7] The guide specification offers an optional clause for at least 40 % fly ash or 100 % recycled aggregate, with data to be submitted.[3] Sika lists recycled glass and Key says owners can choose recycled terrazzo aggregates, with no percentage in either.[8][9][11] Pre-consumer, post-consumer and secondary material are different bases, so a recycled-content figure is only meaningful where its basis is stated; that is our interpretation.
What do the documents declare for thickness, strength, abrasion, slip and fire?
Table 1 lists the cement-bound products and Table 2 the epoxy ones. Values are as printed, with each cell's standard; "not stated" means the document we read does not give it.

Read the tables as separate products under separate tests, not as a ranking. The abrasion statements use a Böhme volume loss, Taber mass losses with two different wheels and an EN 13892-4 class, which cannot be put on one scale. Flowcrete adds that the final anti-slip properties depend on the application method, the size and shape of the topcoat aggregate, the degree of abrasion, maintenance and dirt.[10] Grandinetti says its polished tiles are anti-slip for interiors and its textured version suits surfaces needing more grip.[4] The guide specification asks for a penetrating sealer that does not discolour the terrazzo and produces a slip-resistant surface.[3]
None of the documents we read gives thermal conductivity, sound insulation or impact-sound figures for terrazzo, so we give none. Grandinetti's EPD describes tiles for interiors in one place and floors and walls for interiors and exteriors in another, and EN 13748-1 is the standard for internal use; we show both and do not reconcile them.[4][1]
What do the documents say about joints, movement, installation and maintenance?
For poured cement terrazzo the guide specification sets divider strips of brass, zinc or plastic, 30 mm deep, set in the plastic underbed; where divisions are not drawn, the field is divided into squares or rectangles of uniform size not more than 1,800 mm on a side. Control-joint strips go over subfloor expansion joints and run the full depth of the underbed, and expansion strips go over control, construction and expansion joints; edging strips go where terrazzo meets other floor types.[3] Its note adds that where structural movement that may injure the terrazzo is anticipated, installation should use the sand-cushion (floating) method instead of bonding.[3]
For tiles and slabs, Grandinetti says a protective treatment is required after installation and that, if installed to its instructions, the product needs no ordinary maintenance over a 50-year life in its scenario; EUVAL recommends impregnation after laying and says slabs are reusable in principle but hard to remove without breaking.[4][5]
For epoxy systems the data sheets set conditions on the substrate and the room. Sika's Canadian sheet asks for concrete moisture of 4 % by mass or less, ambient and substrate temperatures of 10 to 30 °C, air humidity of 85 % or less, concrete of at least 25 MPa at 28 days, about 18 to 24 hours before initial grinding and about 7 days to full cure. It limits use to interiors, says the product will discolour under UV, and advises against cracked or unsound substrates and negative-side waterproofing.[8] Flowcrete gives light traffic after 24, 16 or 10 hours and full traffic after 72, 48 or 36 hours at 10, 20 or 30 °C.[10] The Key EPD says regular cleaning and recoating over a 60-year building life are required in its PCR scenario, and Terroxy's EPD uses 30 years of market service life and 60 years of technical service life for commercial use.[11][12] The resin sheets we read do not describe how structural movement joints are carried through the finish.
How much carbon do the EPDs declare?
The table uses six EPDs: four in the International EPD System under EN 15804+A2 and two from NSF under its resinous floor coatings PCR. On 19 October 2026 the EPD Library showed the first four as Valid and the NSF listing showed the last two within their validity periods. The table gives A1–A3 as printed, with other modules for context; it converts nothing and ranks nothing.

The rows cannot be set side by side. Declared units run from a kilogram of installed mortar to a square metre over 60 years, boundaries from cradle to gate with options to cradle to grave, the Key EPD counts aggregate in A5 while the Terroxy EPD's reference flow includes it, the GWP indicators differ in how they treat biogenic carbon, and the four International EPD System PDFs cite three PCR versions.[4][5][6][7][11][12] Two points are visible within individual EPDs, and we do not generalise them: in Grandinetti's EPD, the 1,390 km lorry scenario gives an A4 of 13.9 against 17.5 for A1–A3; and in the resin EPDs the replacement scenario is large: Key's B4 of 20.9 exceeds its A1–A3 of 19.0 in the 30-year market-service-life table and Terroxy's totals fall from 178 to 62 as the assumed service life lengthens.[4][11][12] The negative biogenic A1–A3 values of EUVAL (−1.42) and Grandinetti (−1.37) sit beside their fossil figures and we do not net them.[5][4]
On 19 October 2026 the EPD Library listed Grandinetti's EPD as version :003 (version date 2026-06-18), but the file its download link served that day was identical to the PDF we read, which prints version :001 (2025-11-26) and lists only the original version in its history. Every Grandinetti figure here is from that PDF; we could not see what, if anything, changed in :003. We also read a Norwegian EPD for terrazzo cast on site, cement-bound (Herrljunga Terrazzo, HT - Lykke), but its printed validity ended on 28 September 2026, it was no longer listed in the EPD-Global registry on 19 October 2026, and we use none of its figures.[4][13]
When to specify it, and when not
Precast tiles and slabs
Makers name: interior floors, stairs and walls where the chips and colour are the design
The makers name schools, airports, stations, hospitals, hotels and museums (EUVAL) and floors and walls in residential, commercial and public spaces (Grandinetti); these are manufacturer statements.[5][4] EN 13748-1 covers internal use; Grandinetti's EPD calls for a protective treatment after installation and EUVAL's recommends impregnation after laying.[1][4][5] Mass is a design input: 20 to 50 kg/m² for 1.2 to 2 cm tiles and 52 to 104 kg/m² for 2 to 4 cm slabs, so the floor structure and, on a stair or wall, the fixing need checking (our reading of the figures).[4][5] Ask for the declaration of performance and slip and abrasion results for the exact product and finish: EUVAL's EPD prints a class table by surface type rather than a tested class for a named product, and Agglotech's prints no technical values.[5][6]
Poured cement terrazzo and movement
Check first: subfloor movement, joint layout, curing and grinding
The guide specification treats joints as part of the design: divider and control strips are laid out on drawings, expansion strips sit over structural joints, and a floating sand-cushion installation replaces bonding where movement could injure the terrazzo. It also requires at least 70 % exposed marble chips after fine grinding and a surface that varies by no more than 2 mm per metre, and one of its bracketed finishing options sets a finished topping of at least 13 mm.[3] These are requirements of one US specification, not general rules, and the documents we read give no crack guidance for terrazzo. weber's EPD gives a flexural strength of about 7 N/mm² for its topping and no slip, abrasion or fire values.[7]
Epoxy terrazzo
Makers position it for: thin build-ups, seamless interiors. Check first: substrate moisture, cracks, interior-only limits
The makers describe 6 to 10 mm systems; Sika's Canadian sheet claims light weight and easy jointing with adjacent finishes, and Flowcrete gives traffic times from 10 to 72 hours depending on temperature.[8][9][10] Against that, Sika limits its Canadian system to interiors, substrates at 4 % moisture by mass or less and experienced applicators, warns of UV discolouration, and leaves the mix design to the applicator.[8] Key's system includes a membrane and primer, Terroxy lists an iso-crack membrane as optional but recommended, and Key's EPD counts regular recoating and replacement over the building life.[11][12] A resin floor is seamless in the makers' descriptions, whereas a poured cement floor shows divider strips by design; the documents do not weigh the two.
Slip, finish and maintenance
Check first: the slip test for the finish and sealer to be installed
Slip values come from different tests (EN 14231 USRV values, EN 13036-4, the DIN 51130 ramp scale); Grandinetti prints different values for matt and polished tiles, and Flowcrete ties the result to application, topcoat aggregate, wear, maintenance and dirt. A specifier who needs a class should ask for the test report of the product in the finish to be installed.[4][5][10] The guide specification calls for a terrazzo cleaner with a pH between 7 and 10 and a penetrating sealer that produces a slip-resistant surface.[3]
What the documents do not settle
Gaps
We found no thermal or acoustic figures and no document that quantifies a comparison between terrazzo and another floor finish (Sika's Canadian sheet claims very low life-cycle costs compared with other finishes, without figures). We found no valid EPD for cement terrazzo cast on site: on 19 October 2026 an EPD-Global search for "terrazzo" and "Herrljunga" returned precast products and epoxy systems only, and we did not search every programme. We opened no certificate behind any emissions or conformity statement, and the documents we read give no cost figures.

Frequently asked questions about terrazzo flooring
What is terrazzo flooring made of?
Terrazzo flooring is made of chips of marble, granite, glass or other aggregate in a binder, then ground and polished. The documents we read describe cement binders (precast tiles and slabs, poured toppings) and epoxy resin binders. This page is about the building material, not the terrazzo-look patterns printed on laminate or plastic.
What is the difference between cement-bound and resin-bound terrazzo?
In the documents we read, cement-bound products are tiles and slabs of 1.2 to 4 cm, or toppings of 8 to 60 mm, declared against EN 13748-1 or EN 13813. Epoxy systems are declared at about 6 to 10 mm against test methods such as Taber abrasion or EN 13892-4, so their values are not directly comparable.
Is terrazzo flooring slip resistant?
It depends on the finish and the test. Grandinetti declares USRV13 (matt) to USRV47 (polished) under EN 14231:2003 and Flowcrete declares a dry value above 40 under EN 13036-4 for Mirrazzo. EUVAL's EPD prints a DIN 51130 table that pairs surfaces with classes (polished R9 or R10, brushed R9, sanded R11) without saying which applies to a given product.
Does terrazzo flooring contain recycled material?
Some products do, and the documents state it differently. Agglotech's EPD says its marble grit is produced from marble fragments and quarry waste, yet declares no secondary material. EUVAL describes a high pre-consumer recycled content without a percentage. Grandinetti and weber declare 0 % post-consumer recycled material by mass. Sika and Key name recycled glass or recycled terrazzo as optional aggregates.
What carbon figures do terrazzo EPDs declare?
For A1 to A3, the cement-bound EPDs declare 9.74 kg CO2e per m² of 2 cm slab (EUVAL) and 17.5 per m² of 2 cm tile (Grandinetti). Separately, the epoxy EPDs declare 19.0 per m² for Key Epoxy Terrazzo (resin products only; aggregates counted in A5) and 51.9 per m² for Terroxy RLF (a reference flow including aggregate; excluding biogenic carbon). The declared units, modules, indicators and rules differ, so the figures are not comparable.
The bottom line on terrazzo flooring
Terrazzo flooring is two families of product with different documents: cement-bound tiles, slabs and toppings, and epoxy systems. The documents tie the result to finish, substrate and installation; they give no thermal or acoustic data, and their slip, abrasion and carbon values cannot be compared across makers without matching the test, the unit and the boundary.
