Concrete isn’t solid — it’s a network beneath the surface.
At the microscopic level, concrete behaves like a hard sponge. It contains a network of capillaries and pores that allow water, chlorides, and corrosive agents to migrate into the structure — leading to micro-cracking, reduced alkalinity, and corrosion of embedded steel reinforcement.
Traditional approaches like surface coatings, membranes or silicate “crystal growth” densifiers often only treat the surface or fail to fully block ingress and internal reactions.
Three Pillars of Protection
Strengthening Concrete from Within
After penetrating the concrete’s internal structure, SRS 4000 Concrete Guard goes to work where deterioration begins — deep inside. Once within the matrix, it reacts with free calcium hydroxide and moisture, initiating a chemical transformation that forms new calcium silicate hydrate (C-S-H) — the same mineral that gives concrete its natural strength and density.
​
This mineral growth isn’t a coating or filler — it’s an integral part of the concrete itself. As these reactions continue, the material densifies from within, closing micro-cracks, bonding loose particles, and reducing porosity by up to 90%. The result is a stronger, more unified structure that naturally resists water intrusion and the long-term damage it causes.
Water & Chloride Protection
Porosity Reduction + Densification
Concrete Guard doesn’t block water by creating a surface film — it transforms the concrete internally, turning weak, porous zones into dense, durable C-S-H mineral structure for long-term protection.
Corrosion Protection Science
Alkalinity Restoration + Mineral Barrier Around Steel
SRS 4000 Concrete Guard penetrates deeply to restore the concrete’s natural pH balance and build a mineral shield that resists chloride and oxygen intrusion. The result is a denser matrix and a more stable environment around embedded steel—slowing corrosion without the need for surface coatings or reapplication.
Creating a Mineral Shield Around Reinforcing Steel
As concrete loses alkalinity, chlorides reach embedded steel and trigger corrosion. SRS 4000 Concrete Guard restores pH and forms new C-S-H minerals that densify the matrix, reducing porosity and sealing pathways for oxygen and chloride intrusion.
This internal mineral barrier stabilizes the environment around the steel—slowing corrosion at its source. Pair with SRS Steel Guard for full rebar passivation for aggressive corrosive conditions.
Structural Strength & Durability
Beyond corrosion control, SRS 4000 Concrete Guard strengthens the concrete itself.
As new C-S-H minerals form, internal voids close and density increases—improving compressive strength and reducing micro-cracking.
This densified matrix resists freeze-thaw cycles, abrasion, and chemical attack, providing long-term structural integrityeven under extreme industrial and marine conditions.
Military-Grade Protection
C-S-H Formation + Structural Enhancement
Concrete Guard strengthens from within, forming new C-S-H minerals that seal microcracks and densify the matrix—boosting compressive strength, reducing permeability, and defending against abrasion, freeze-thaw, and chemical attack.
