Elastic Recovery vs Joint Longevity

Ordinary asphalt or tar joint fillers deform permanently under summer sun and squeeze out under winter compression. SL-90’s 118% polyurethane polymer recovery ensures the joint seal springs back flush with the pavement surface season after season.

Horizontal Joint Sealing

Where & How SL-90 Self-Leveling PU Sealant Performs

One-part elastomeric polyurethane formulated for high-efficiency horizontal concrete expansion joints, warehouse floors, parking decks, and airport aprons without tooling.

Self-Leveling Sealant Fluidity and Automatic Smoothing Action Closeup

Self-Smoothing Flow

Automatic Flow & Self-Smoothing

Flows freely under gravity into concrete saw-cut and expansion joints up to 40 mm wide, completely eliminating manual troweling and tooling labor.

Cuts joint installation labor cost by over 50%
Forms a perfectly flush, bubble-free horizontal finish

Warehouse Concrete Expansion Joint Filled with Self-Leveling Sealant

Logistics Warehouses

Logistics Centers & Industrial Slabs

Protects concrete joint shoulders from edge spalling caused by hard-wheeled forklift traffic, pallet jacks, and heavy automated guided vehicles (AGVs).

Shore A Hardness: 30 ± 5 for flexible movement absorption
ASTM C920 Type S, Grade P, Class 25 compliant

Forklift Wheel Traffic Over Cured Concrete Expansion Joint

Wheel Abrasion Resistant

Multi-Story Parking Decks & Ramps

Waterproofs vehicular slabs against de-icing salts, motor oil drips, fuels, and continuous tire rolling friction across multi-level parking structures.

Movement capability: ±25% of original joint width
Resists hydraulic fluids, motor oils, and road salts

Concrete Expansion Joint Sealing on Runway and Highway

Airports & Runways

Highway Pavements & Bridge Decks

Forms a weather-tight elastic barrier preventing water ingress into road base subgrades, preventing frost-heave damage and concrete joint blowout.

Tensile recovery > 90% after prolonged compression
Service temperature: -40°C to +80°C
