Airport Concrete Crack Sealers for Runways, Taxiways & Aprons

Transpo manufactures industrial-grade concrete sealers engineered for the demanding conditions of airport pavement. Runways, taxiways, and aprons endure heavy aircraft loading, thermal cycling, fuel and de-icing chemical exposure, and strict requirements for controlling foreign object debris (FOD).

Cracks in airfield concrete can create FOD hazards, allow water infiltration, and accelerate pavement deterioration. Transpo’s concrete crack sealers help airport teams seal cracks quickly and durably, protecting pavement performance while minimizing disruption to airfield operations. Learn more now.

Transpo's Airport Concrete Crack Sealers

Transpo’s crack sealants use low-viscosity resin that wicks deep into narrow cracks, bonds to the crack walls, and seals the concrete against moisture and contaminants, restoring strength and reducing chloride permeability. Transpo sealers are installed in a single application with no special equipment, delivering deep crack penetration, moisture protection, chemical resistance, and long-term durability.

T-70 HMWM Concrete Crack Sealer

T-78 MMA Concrete Crack Sealer

T-70 uses a high molecular weight methacrylate resin. Its low modulus and high elongation suit moving and thermal cracks in runways, taxiways, and hangar floors

T-78 is a rapid-cure methyl methacrylate system that sets in roughly 45 minutes at 70°F, ideal when a runway can only close briefly.

Concrete Repair: Critical for Airport Infrastructure

Poorly or unsealed sealed cracks in concrete can allow water to penetrate the slab, reach the base, and compromise pavement performance. Over time, water infiltration can weaken load transfer, accelerate steel corrosion, and contribute to spalling—turning a minor crack-sealing need into a costly slab repair.

Airfield concrete is exposed to freeze-thaw cycles, heavy aircraft loading, thermal movement, and aggressive chemicals, all of which can cause cracks to grow and deteriorate. Early, properly executed crack sealing helps prevent moisture intrusion and limit further damage.

Best Practices: Sealing Airport Concrete Cracks

Successful concrete crack repair depends on surface preparation: cracks must be clean, dry, and free of oil and old sealant so the resin can penetrate sound concrete. Sealing cracks in concrete is ongoing, with regular airfield inspection catching new, non-structural cracks early, before they progress to slab repair, maximizing long-term durability.

For airport maintenance teams, sealing concrete cracks early is one of the most cost-effective ways to protect pavement life, reduce repair costs, and maintain a safe operating environment for aircraft and the public.

Frequently Asked Questions

What is the best way to repair airport concrete cracks?

For small to medium non-structural cracks, a penetrating crack sealant like T-70 or T-78 fills and bonds in one application. Larger structural cracks may need resin injection or slab repair.
