TCI SprayStrong Plus+
Enhances Concrete Hydrophobicity.
TCI SprayStrong Plus+ is engineered to PROTECT concrete infrastructure from corrosion and environmental contaminants. It forms a protective film on reinforcing steel, reduces substrate porosity, EXTENDS THE SERVICE LIFE of concrete pipes, and converts active corrosion into a stable, inert layer. The formulation also minimizes water intrusion and provides RESISTANCE to acids & chlorides.

Pure Muriatic Acid Test
TCI SprayStrong Plus+
This demonstration features pure muriatic acid, a concentration not typically found in natural environments. However, the impact of this highly corrosive substance on pipes illustrates its significant deteriorating effects.
Chemical Process of Concrete Deterioration
-
New concrete has a high pH which continually regenerates the protective coating on the rebar.​
​
-
Concrete is extremely porous.​
​
-
Over time, oxygen & moisture, chlorides, carbon dioxide and other environmental contaminants migrate thru the concrete down to the reinforcing steel.​
​
-
​A drop in pH will occur over time as a result of the concrete’s exposure to carbon dioxide, chlorides, acids and other chemicals and environmental contaminates.
​
-
The pathways for these chlorides and pH reducing contaminants to enter the concrete are cracks and gel pores.
​
-
Expansive stresses on surrounding concrete (<20,000 psi) causes the rebar to swell and the concrete to delaminate from the reinforcing and the concrete to crack.
​
-
With the pH compromised and more contaminates migrating through cracking the deterioration cycle is accelerated, and corrosion begins to travel through the bar to other areas far beyond the cracking.
​
-
Traditional methods of blocking these pathways, sealants, coatings and water repellents may provide short term protection for new concrete, but breakdown with time as they are organic.
​
-
Patching without pacifying the steel in surrounding concrete will lead to accelerated corrosion (anodic ring).
