Transpo® T-70 Crack Sealer

Sealate® Crack Sealer consists of specially formulated, high molecular weight methacrylate (HMWM) resin materials that strengthen and extend the life of concrete. With an easy single application, Sealate® deeply penetrates, quickly fills and bonds cracks, and seals pores in existing concrete including airport runways, taxiways, aprons and various concrete structures and surfaces.

Features and Advantages

  • Very Low ViscositySealate Diagram
  • Deep Crack Penetration
  • Fills and Bonds Cracks
  • Fast Cure Reduces Down Time
  • Easy Single Application
  • Requires No Special Equipment
  • Low Volatility
  • Strengthens and Extends the Life of Concrete

The very low viscosity and surface tension of the Sealate® formulations allow it to easily penetrate and fill deep cracks in existing concrete. It bonds well to the inner walls of the cracks thereby restoring much of the original strength and reducing crack propagation. The significantly lower modulus and increased tensile elongation of Sealate® provides better compatibility with moving cracks and thermal stresses, plus its rapid curing time assures a quick return to service, which is extremely important to an airport.


Application of Sealate® requires minimal labor and no specialized equipment which results in low installation costs. The use of Sealate® on concrete surfaces and structures reduces chloride permeability thus protecting it from further deterioration. Sealate® can be used for crack sealing and filling on;

  • Aircraft Runways and Hangars
  • Parking Garages
  • Industrial Floors
  • Concrete Roads
  • Precast Concrete Elements
