What are the main culprits to concrete deterioration?

Water, Salt & Contaminants! 

What is the most common type of salt damage?

Spalling is the most common type of salt damage caused by corrosion of embedded steel reinforcement. This typically occurs due to micro-cracking (<2mm) which provides pathways for water and salt to enter the depths of the concrete.

Does PRO Tek Concrete replace traditional cure and seals?

Yes, PRO Tek Concrete not only cures and seals, it fortifies concrete due to its hydrophilic nature and can be used on both new pours as well as older concrete.

What causes surface crazing and is it a structural concern?

Low humidity, high air temperature, intense sunlight, or drying winds, alone or combined, can speed up surface drying, leading to crazing. Crazing manifests as fine surface cracks resembling spider webs or shattered glass. If moisture evaporates too rapidly from the top of a concrete slab, crazing cracks may develop. Though they may be unsightly, crazing cracks typically do not pose structural risks.

What is the main problem with improper curing?

Mortal lift off occurs in 99% of cases from lack of proper curing.

What is the typically curing time and who does PRO Tek concrete act as a waterproofer?

It stops water intrusion with just one application on the negative side of the structure, replacing air in capillaries and voids with aero silica gel, without altering the intended characteristics of air-entrained concrete. Over time, the aero silica gel hardens, forming a waterproofed capillary and pore structure, usually within less than 28 days.

Which two aggregates are notorious for their water absorption abilities, leading to substantial damage to concrete when subjected to freeze/thaw cycles?

Sandstone & Limestone
