A hospital floor is judged by three tests before colour or grain is discussed: whether it can be cleaned to the standard the infection-control team writes down, whether it adds fuel to a fire, and whether it still grips when a wet trolley wheel crosses it. SPC flooring - stone plastic composite, also sold as stone crystal flooring or stone-plastic lock composite flooring - is a rigid plank built from calcium carbonate (natural stone powder or limestone powder), PVC resin, a calcium-zinc stabilizer and a lubricant, pressed into a high-density core, finished with a printed wear layer and usually edged with a click-lock profile. In healthcare interiors it competes with sheet vinyl, rubber and ceramic tile because it combines a closed-cell waterproof core, a dense stain-resistant surface and glue-free installation in one product.

This guide is written for the people who write and approve that specification: estates and facilities teams, infection-control leads, clinical planners, M&E consultants and the contractors who have to deliver the floor inside a live building. It sets out the parameters, the values to demand, the evidence to request and the site conditions that decide whether the specification survives contact with a real ward.

Why healthcare flooring specifications fail in practice

Most flooring failures in healthcare projects are specification failures rather than product failures, and they repeat in three patterns.

The first is a single slip claim applied to a whole building. A corridor, a sluice room, a shower room and a reception are cleaned differently, are wet for different lengths of time and are trafficked by different wheels. A floor that is acceptable in a dry consulting room is not automatically acceptable at the entrance to a wet room. The R classification has to be set zone by zone, and the report attached to it has to name the surface texture that was tested, because the same core with a different texture will produce a different result.

The second is a fire class quoted without a paper trail. B1 and self-extinguishing are product claims; they become usable evidence only when the test report names the product, the thickness and the manufacturing site. A certificate issued for one thickness or one factory cannot be carried across to another.

The third is cleanability asserted from a photograph. Dense surfaces and tight joints look the same on a sample board as they do on a claim sheet. What separates them is measurable: water absorption, stain behaviour and whether the core can take on moisture at all.

Retrofit conditions add a fourth pressure. Healthcare projects are frequently delivered in occupied or partially occupied buildings, which means the floor has to be installed in phases, with limited wet trades. The SPC installation envelope is stated in the product data and should be written into the programme: installation at 18-30 degrees C and post-installation ambient temperature of 13-37.7 degrees C, relative humidity of 65% or less, concrete subfloor moisture of 2% or less (1.5% or less where underfloor heating is present), wood-based subfloor moisture of 12% or less, and subfloor flatness within 2 mm over 2 m. Planks should be acclimated in their original packaging on site for 24-48 hours, an expansion gap of 5-12 mm must be left at walls and fixed objects, and a 6-mil polyethylene vapour barrier is recommended for ground-floor concrete installations. SPC is waterproof but it is not a vapour barrier, so prolonged moisture from below can still cause mould.

What the SPC supply base looks like in 2026

SPC is no longer a niche resilient product, and the published numbers explain why procurement teams see so many suppliers. Dataintelo estimated the global SPC flooring market at USD 9.8 billion for 2025, while Grand View Research reported USD 5.9 billion for the same year under a narrower definition of pure SPC; the gap is a scope difference, not a contradiction, and it is a reminder to check how any market figure is defined before it enters a business case. Within that market, Dataintelo reported that the rigid-core sub-type held a 74.2% revenue share in 2025. On the supply side, OEC data shows China as the largest exporter of plastic floor coverings under HS 391810, at USD 4.97 billion in 2024.

The practical consequence for a hospital project is that product quality is no longer the differentiator it was; documentation quality is. Two suppliers can offer the same plank construction and differ entirely in whether they can produce a test report that survives a technical review.

Terminology is the other trap. PEI is an abrasion classification used in ceramic tile specifications, and the building and decoration benchmark is PEI 3 to 5, with PEI 4 or higher for commercial and public areas. SPC wear is usually expressed differently, in cycles and in a wear grade; the product data for the Monalisa Eir SPC Floor, for example, states wear resistance of 6,000-15,000 cycles and a T-grade wear rating. A hospital that uses tile in wet cores and SPC in wards will have both systems in the same tender document, and both requirements must be written explicitly rather than converted into each other.

Monalisa Group Co., Ltd. (SZSE: 002918) is a Foshan-based manufacturer founded in 1992 that produces ceramic tiles, sintered stone slabs and SPC floor, and operates four production bases with 37 production lines. Its SPC range for this application is the Eir SPC Floor, model ME26009-5, supplied in 1220x180 mm (48x7 in) and 1524x228 mm (60x9 in) formats at 4, 5, 6, 7 or 8 mm thickness with an EIR textured surface.

The specification set: cleanability, fire, slip and wear

Cleanability and infection-control routines

Cleanability in a healthcare setting is a core property, not a surface coating. The Monalisa Eir SPC Floor uses a closed-cell core with water absorption of 0.05% or less, which means standing water does not cause warping, swelling or mould, and the surface is described as dense, stain-resistant and easy to maintain. The product contains no formaldehyde, benzene or other harmful substances, and is described as mould and pest resistant - no mould growth, insect-proof.

Two construction details support cleaning routines as much as the surface does. The click-lock system allows glue-free installation, so the number of adhesive joints that can trap residue is reduced; and the planks can be specified with a built-in IXPE acoustic pad, which removes the need for a separate underlay layer under the floor. What the specification must still control is the detail at the perimeter: wall junctions, door thresholds and the transition to wet areas are where cleaning protocols and water ingress both concentrate, and those details belong in the drawings, not in the product data sheet.

Fire performance: B1 and self-extinguishing

The Eir SPC Floor carries a B1 fire rating and is described as self-extinguishing. In a healthcare building those two words answer different questions: B1 addresses contribution to fire growth in a compartment, and self-extinguishing addresses whether the material continues to burn once the ignition source is removed. The specification should require the test report for the specified thickness and the specified factory, and the report should be cross-checked against the invoice and the packing list at delivery.

Slip resistance: R9 to R11, with R10 or higher in bathrooms

The building and decoration benchmark for slip resistance is R9 to R11, with bathrooms requiring R10 or higher. That band is the correct way to express the requirement because it is the language contractors, flooring subcontractors and safety auditors already use on drawings and handover documents.

SPC product data often expresses grip differently. The Eir SPC Floor states anti-slip performance as increased friction when wet, with a friction coefficient of 0.6 or above. The friction coefficient and the R classification are different measurements produced by different test methods, so a specification that mixes them creates an unverifiable claim. The safe approach is to write the R class for each zone, ask for the corresponding report against the exact surface texture to be supplied, and treat the friction coefficient as supporting information rather than a substitute.

Where the hospital wants a margin of safety, the zones to upgrade are predictable: entrances exposed to rainwater, sluice and dirty-utility rooms, shower and bathroom floors, ramps, and any area cleaned by machine rather than mop.

Abrasion and wear: PEI 4 and wear cycles

For commercial and public areas, the abrasion benchmark is PEI 4 or higher where ceramic tile is specified. For SPC, the equivalent requirement is written as a wear cycle count: the Eir SPC Floor is rated at 6,000-15,000 cycles with a T-grade wear rating. Both belong in the same document when a project mixes materials, because a value transferred from one system to the other is not a specification.

Wear is also a function of the core. The high-density stone-plastic core is described in the product data as providing excellent indentation resistance, and as ten times more impact-resistant than WPC, which is the property that matters for trolley wheels, mobile imaging equipment, beds and the loaded cages that move through service corridors.

The supporting numbers: stability, acoustics and emissions

Three further values complete the set. Dimensional stability is stated as shrinkage of 1 per mille or less, with minimal expansion and contraction, which aligns with the commercial-grade requirement of 0.10% or less under EN ISO 23999. Impact sound is reduced by the built-in IXPE pad by up to 18 dB, with the application data quoting a reduction of 18-22 dB (delta Lw), which is relevant for wards, consulting rooms and any space where night-time noise carries. On emissions, the benchmark worth requesting is GREENGUARD Gold, which under UL 2818 requires testing for more than 10,000 chemicals and enforces strict VOC limits; the product itself is stated to contain no formaldehyde or benzene.

Step-by-step: building the specification package

1. Zone the building and set the slip class by zone. Produce a single drawing that marks every area as dry, occasionally wet or wet. Assign R9 to dry clinical and administrative space, R10 or higher to bathrooms, shower rooms and sluice rooms, and review entrances and ramps separately. The output is a schedule, not a sentence in a general note.
2. Fix the fire class and the evidence behind it. Write B1 and self-extinguishing into the performance section and require a test report that names the product model, the thickness and the factory. Reject certificates that reference a family name without the model.
3. Write cleanability as a measurable requirement. Specify water absorption of 0.05% or less, a dense stain-resistant surface, no formaldehyde or benzene, and mould resistance. Add the detail drawings for wall junctions, thresholds and wet-area perimeters, because those are the points where a cleaning protocol succeeds or fails.
4. Set abrasion and wear in both unit systems. State PEI 4 or higher for ceramic tile used in commercial and public areas, and the wear cycle requirement (6,000-15,000 cycles, T-grade in the product data) for the SPC areas.
5. Lock the construction. Confirm thickness from 4 to 8 mm, the plank format (1220x180 mm or 1524x228 mm on the Eir SPC Floor), the EIR textured surface, the attached IXPE acoustic pad and the click-lock edge. Thickness and texture both influence the slip and acoustic results, so they belong in the same clause as those results.
6. Define the site conditions and the installation method in the tender. Include the acclimation period of 24-48 hours, the 5-12 mm expansion gap, subfloor flatness of 2 mm over 2 m, the moisture limits for concrete and wood subfloors, the vapour barrier on ground-floor concrete, and the underfloor heating limit of 27 degrees C floor surface temperature. State that the floor is installed as a floating system with click-lock joints, that it must not go over soft carpet or soft PVC underlayment, and that any area receiving cabinets must be fully glued to the subfloor.
7. Require batch inspection and a mock-up room. Every batch of SPC flooring is subject to a pre-shipment inspection covering appearance, overall dimensions and dimensional tolerances, deviation in mass per unit area, residual indentation and peel strength. Ask for those records, then approve a mock-up in one room before the main order is released, so that the joint pattern, the perimeter detailing and the cleaning routine can be tested together.

Where this specification is applied

Inpatient wards and corridors. The dominant loads are beds, trolleys and cleaning machines rather than footfall alone. Thickness, indentation resistance and wear cycles carry the specification here, while the acoustic pad addresses noise transfer between floors and along corridors.

Clinics and treatment rooms. Cleaning frequency is higher and the floor is exposed to repeated detergent contact. A dense, stain-resistant surface with low water absorption and glue-free joints reduces the number of places where residue collects.

Bathrooms, shower rooms and sluice rooms. This is the zone where the R10 or higher requirement applies and where the waterproof core earns its place: 100% waterproof construction with water absorption of 0.05% or less, and no swelling under standing water.

Libraries and exhibition halls. Public and institutional spaces apply the same logic with a different traffic profile: long opening hours, heavy footfall, and a need for quick cleaning between events. The hospital specification transfers directly, which is why the same parameter set is now used across medical facilities, schools, libraries, exhibition halls and commercial buildings.

Project records shape how institutional buyers read a supplier. Monalisa's public-institutional record sits mainly in architectural ceramics: eight venues of the Beijing Olympic Games, ten venues of the Guangzhou Asian Games, the Hong Kong-Zhuhai-Macao Bridge, the China Pavilion at Expo 2020 Dubai and the official architectural ceramics for the 19th Asian Games Hangzhou 2022. A relevant institutional delivery is the JOGYAKARTA AIRPORT project in Indonesia, a two-year, 80,000 square metre installation of unglazed porcelain tiles for a municipal government client that recorded a 30% lower life-cycle maintenance cost, a 15% saving on grouting materials and labour through tight-joint installation, and a breakage rate below 0.3%. Those are tile figures, not SPC figures, but the reasoning they demonstrate - that specification discipline shows up in maintenance cost rather than in the purchase price - is exactly the argument a hospital board will ask for.

Conclusion

Specifying SPC flooring for a hospital or clinic is a documentation exercise wrapped around a product decision. The product decision is straightforward: a rigid stone-plastic plank with a closed-cell core, water absorption of 0.05% or less, a B1 fire rating, a dense easy-clean surface and grip that improves when wet. The documentation exercise is what protects the project - a slip class set zone by zone, a fire report that names the model and the factory, a wear requirement written in the unit system that matches the material, and site conditions that are checked before the first plank is laid rather than after the first joint opens.

Get those four things right and the floor stops being a maintenance item and becomes part of the infection-control and fire-safety strategy. Get them wrong and the discussion moves to replacement, in a building that cannot easily close.
