BRCGS Issue 9 Clause 4.4.1 requires flooring in food contact areas to be non-porous, cleanable, and designed to prevent contamination. Nitrile (NBR) rubber tiles or sheet, fully bonded, with sealed joints and cove skirting, meets this requirement. SBR rubber is not suitable for food contact zones due to poor oil resistance and surface degradation. BRCGS also requires cove skirting at all floor-wall junctions - a mandatory requirement auditors will specifically check.

HSE HSSG 156 recommends a minimum PTV of 36 (wet), equivalent to DIN 51130 R11, for general food production zones. In zones where oil, fat, or food-grade lubricants are present - cooking lines, dairy, meat processing, bakeries - specify R12. For meat, poultry, and fish processing at its most extreme contamination, specify R13. Using R10 or R11 in oil/fat environments is a compliance risk and a personal injury liability.

SBR rubber can be used in back-of-house and non-production areas - dry goods stores, corridors, staff changing rooms, despatch areas, and offices. It must NOT be used in any area where oil, fat, meat, dairy products, or food-grade chemicals are present. SBR has poor oil and fat resistance, degrades rapidly when exposed to animal fats or vegetable oils, developing surface cracks that harbour bacteria. This is a direct BRCGS and HACCP compliance failure. Specify Nitrile (NBR) rubber for all production, preparation, and cooking zones.

Yes. BRCGS Global Standard for Food Safety Issue 9, Clause 4.4.1 states that the junction between floors and walls shall be designed to facilitate cleaning, which auditors interpret as requiring cove skirting at all floor-wall junctions in food contact areas. The 90-degree angle between floor and wall is a critical harbourage point for water, fat, bacteria, and debris. Auditors will specifically inspect floor-wall junctions and will raise a nonconformance if open joints or missing coving are found. Rubber coving strip with a minimum 50mm radius cove former is the standard specification.

For pedestrian-only food production zones, 9-12mm nitrile rubber is standard. For wheeled trolley or pallet truck traffic, 12-15mm. For forklift truck traffic, 15-20mm with full-bond installation. In cold stores with FLT traffic, 15mm minimum is required to prevent compression failure at low temperatures. Anti-fatigue drainage mats at fixed workstations are typically 9-15mm. Always specify minimum 12mm for cooking lines and meat processing due to the combination of FLT traffic, high contamination, and frequent hot wash-down.

Nitrile rubber can be installed over sound, flat concrete (35 N/mm2 minimum, moisture content 75% RH or below). Existing quarry tiles can be overlaid if they are fully bonded, flat, and not hollow-sounding. Any loose, cracked, or hollow tiles must be removed and the subfloor levelled before rubber overlay. In food manufacturing, it is preferable to remove old flooring entirely, as existing tiles may harbour bacteria in grout joints beneath the new rubber. All installations must use food-safe, water-based contact adhesive with full-bond coverage.

For cold stores operating at 0C to -25C, nitrile (NBR) rubber is the primary specification - it retains flexibility down to -40C and has excellent oil resistance for any condensed fat/food residues. EPDM rubber is also suitable for cold stores but has poor oil resistance - use EPDM only in cold stores where no food products or fats are handled. For blast freezers at -30C to -40C, specify nitrile rubber rated for the operating temperature. All cold store rubber flooring should be fully bonded to prevent ice forming beneath the mat.

With correct specification, installation, and cleaning protocols, nitrile rubber flooring in food manufacturing typically lasts 10-15 years in production zones and 15-20+ years in lower-traffic back-of-house areas. Anti-fatigue drainage mats at workstations - which experience the highest wear - typically need replacement every 3-7 years. Rubber tile systems have a significant advantage over epoxy resin in food factories: individual damaged tiles can be replaced without shutting down the entire production line.
