About Fosroc Trafficguard

Fosroc Trafficguard is the polyurethane traffic-deck range that Fosroc built specifically for surfaces where vehicles, not just people, move day after day. On a car park deck the concrete faces a punishing mix of loads at once: standing and turning tyres grinding the surface, water and de-icing salts trying to reach the reinforcement, and the slab itself flexing with temperature and live load. A plain waterproofing membrane will keep water out but shears under tyre scrub; a hard screed resists abrasion but cracks as the deck moves. Trafficguard answers both by stacking purpose-made layers, primer, a flexible topcoat or membrane, anti-slip grain and a tough wear course, that are laid wet-on-wet and cure into a single bonded skin. The elastomeric layers stretch with the structure while the grain-loaded wear course takes the beating from wheels.

In India, Space Arc supplies and applies the Trafficguard UR family (UR100 through UR250, with UR150 the workhorse specification) across Delhi NCR and pan-India. These grades differ mainly in build thickness and wear-course robustness for light, medium or heavy traffic zones, so a designer can specify a lighter system for a residential podium and a heavier one for a busy commercial ramp without changing product families. Because every component is cold-applied and seamless, the system suits occupied buildings and awkward geometries, ramps, upstands, drainage channels, where sheet membranes struggle. As an authorised Fosroc distributor and applicator, Space Arc pairs the right grade to the traffic study, substrate condition and programme, rather than defaulting to a one-size coating.

The technical insight

The system works because it separates two jobs that fight each other and gives each its own layer. The primer opens and wets the concrete capillaries to build adhesion, and anti-slip grain broadcast into it keys the upper coats mechanically. The flexible topcoat/membrane is the moving, waterproofing heart of the system: on Trafficguard UR150 it delivers roughly 200% elongation (ASTM D412) with about 96% recovery, so it bridges dynamic cracks (rated no cracking to ASTM C836) and springs back rather than tearing when the deck flexes under a wheel. Sitting on top, the grain-loaded wear course carries a Shore A hardness around 85 and a coefficient of friction above 0.8 (ASTM F609), which is what gives a wet ramp its skid resistance and lets the surface absorb tyre scrub without abrading through to the membrane. Because the layers react chemically to each other rather than being merely stacked, the interfaces do not delaminate under shear, and the finished skin behaves as one elastic, watertight unit instead of a sandwich of separate films.

Where it is used

• Deck and ramp waterproofing plus traffic protection in multi-storey car parks
• Podium car park slabs over shopping malls, offices and residential towers
• Exposed basement and terrace roof slabs used for parking
• Aircraft hangar floors, transport depots and bus, coach and taxi yards
• Service centres, garages and vehicle workshop floors
• Warehouse and industrial floors subject to forklift and pallet-truck traffic
• Colour-demarcated parking bays, drive lanes and pedestrian walkways using standard and RAL-matched shades
• Line marking over the cured deck using Trafficguard Line Marking Paint (TLMP)

Key advantages

• Flexible elastomeric layers bridge dynamic thermal and shrinkage cracks instead of splitting over them
• Seamless and watertight, with no laps or joints for water to track through on complex deck geometry
• Skid-resistant, grain-loaded wear course gives a safe surface on ramps and in wet conditions
• Purpose-built for tyre abrasion and vehicle loading, not a foot-traffic membrane pressed into deck duty
• Cold liquid-applied, so it wraps around upstands, channels and penetrations that sheet systems cannot
• UV resistant wear course holds appearance on exposed decks and roof-slab parking
• Available in a range of grades (UR100-UR250) so the build is matched to light, medium or heavy traffic zones
• Standard and RAL-matchable colours allow clear bay, lane and pedestrian-zone demarcation

Limitations & considerations

• Not for substrates with rising damp or relative humidity above about 80% (BS 8203 App. A); an osmotic or persistently wet slab must be corrected first
• New concrete must have cured a minimum of 28 days (reach ~80% of properties) before priming
• Primer and wear course are flammable (flash points as low as ~23 C); no naked flames and good ventilation are essential during application
• Do not apply if rain is imminent or if temperatures may fall below 7 C within 24 hours of application
• Above 35 C substrate/ambient temperatures, working practice must change (cool storage, shaded plant, avoid the hottest hours) to control pot life and finish
• The wear course is a sacrificial layer; heavily trafficked zones and ramps need periodic inspection and re-coating over the service life rather than being fit-and-forget

Industry use cases

How we position Fosroc Trafficguard

Position Trafficguard as the vehicular-deck specialist within Space Arc’s Fosroc waterproofing and flooring line-up. Where the deck mainly needs waterproofing with only light foot or occasional traffic, Fosroc Nitoproof 800 is the more economical seamless PU choice; step up to Trafficguard when tyres, ramps and turning loads dominate. For hard-wearing internal industrial slabs poured fresh, pair or contrast with the dry-shake hardener Fosroc Nitoflor Hardtop. Substrate prep before coating typically uses Fosroc Nitomortar repair mortars and Nitoprime primers. Across other brands we carry, this competes with Sika Sikafloor and Dr. Fixit PU deck systems, so the honest recommendation is driven by the traffic study, exposure and budget rather than brand loyalty.
