T-70 HMWM Concrete Crack Sealer

T-70 Crack Sealers are specially formulated High Molecular Weight Methacrylate (HMWM) resin materials that strengthen and extend the life of concrete. With an easy single application, T-70 deeply penetrates, fills, and bonds cracks, and seals pores in existing concrete including roadways, bridges, and various concrete structures and surfaces. 

Application of T-70 requires minimal labor and no specialized equipment which results in low installation costs.

Features and AdvantagesSealate Diagram

  • Deep Crack Penetration
  • Fills and Bonds Cracks
  • Easy Single Application
  • Very Low Viscosity
  • Fast Cure
  • Low Odor
  • Low Volatility



The very low viscosity and surface tension of the T-70® 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 T-70® provides better compatibility with moving cracks and thermal stresses.


When used on concrete surfaces and structures it reduces chloride permeability thus protecting it from further deterioration. T-70 can be used on:

  • Concrete Roads
  • Concrete Bridge Decks
  • Parking Garages
  • Industrial Floors
  • Precast Concrete Elements
  • Premature Cracking in New Concrete
  • Aircraft Runways and Hangers
Transpo T-70 can also be applied through low pressure injection.
