Phoscrete is a excellent alternative to conventional Portland cement-based concrete repair products. It bonds both chemically and mechanically to concrete, and to itself with no cold joints.

Because Phoscrete has both cementitious and polymeric properties, it is non-shrinking, non-brittle, and not prone to cracking. It has high early compression, bond, flexural and tensile strength, making it an excellent choice for concrete repairs.

Phoscrete is safe to use, with no odors or VOCs and all your tools clean up with water. Same for your boots and clothes.

There are tons of benefits to using Phoscrete over conventional concrete repair products, including:

• Works fast in all temperatures
• Very low chloride ion permeability
• No cold joints
• No shrinkage cracks
• Mixes up in less than one minute

After mixing, Phoscrete's liquid activator stops corrosion on contact. Along with preventing rust from forming, Phoscrete also helps to mitigate what’s known as the “halo effect.”

The halo effect occurs when a concrete patch causes rust to form on the rebar at the adjacent to the repair, causing spalling around the perimeter of the patch. This is partly due to the difference in pH between the patching material and concrete.

Conventional Portland cement-based concrete repair products cure with a higher pH than the surrounding concrete pushing the corrosion reaction to the perimeter, Phoscrete cures slightly acidic, acting as an anode, and naturally stops corrosion on the rebar it encapsulates.

Because Phoscrete Activator has a freezing point of -20°F (-29°C) it can be installed even in temperatures below freezing where the water used in conventional concretes will freeze, or take hours to set.

The same Phoscrete formula is used in all temperatures. Set times can be controlled using admixtures (Fast-Set and Slow-Set) and by cooling or supercooling the activator.

Oftentimes, nesting birds prevent crews from repairing bridge substructures in the spring and summer. Because Phoscrete works great even in the cold of winter, the season for concrete repair is extended and the work can be done without disturbing nature.

Phoscrete repairs stand up to freezing and thawing, and also to deicing salts that damage ordinary concrete. Phoscrete has been tested to show a durability factor of >100% and a salt scaling visual rating of 0 after 50 cycles, with very low material loss.

Chlorides in water that penetrate concrete form a current for acceleration of corrosion in reinforcing steel (rebar).

Phoscrete was tested to show a very low chloride ion permeability rating.

In both lab and field testing, Phoscrete has been proven to excel in both restrained and free shrinkage testing. Phoscrete has high tensile strength and high-early bond strength so not only does Phoscrete hold strong to the adjacent concrete, it will not shrink or crack under stress.

Phoscrete actually expands slightly on initial set, increasing the mechanical bond to the adjacent concrete.

Once a repair site is properly prepared, no additional steps are required before installing Phoscrete, so you can save time and money. Phoscrete is often the lowest in-place cost solution for concrete repair, helping you to:

• Save time on site prep and installation
• Eliminate the need for sandblasting
• Save money by completing the repair faster/in one shift
• Repair a larger area in a shorter time period
