SRS-4000 Concrete Guard – Advanced Concrete Densifier & Penetrating Sealer for Surface Strengthening and Long-Term Protection
SRS-4000 Concrete Guard is a high-performance, penetrating concrete densifier and hybrid silicate/siliconate sealer designed to strengthen, protect, and extend the service life of structural concrete. Engineered for commercial, industrial, and infrastructure applications, SRS-4000 penetrates deeply into the concrete substrate, reacts with free calcium, reduces porosity, and enhances durability against moisture, chlorides, abrasion, and environmental exposure.
SRS-4000 increases surface density and reduces permeability, helping improve overall concrete performance and preparing substrates for repair materials, FRP strengthening systems, or protective coating applications.

-
Improve surface hardness for high-traffic environments
-
Prepare concrete substrates for overlays, coatings, or FRP reinforcement
Durability & Corrosion Protection
-
Reduce chloride penetration on bridge decks and parking structures
-
Protect concrete exposed to moisture, salts, and freeze-thaw cycles
-
Improve long-term resistance to corrosion in reinforced concrete
Commercial & Industrial Floors
-
Warehouses, manufacturing floors, loading docks
-
Reduce dusting and increase abrasion resistance
-
Improve chemical resistance and reduce maintenance
Infrastructure & Exterior Concrete
-
Retaining walls, foundation walls, sidewalks, plazas
-
Exterior balconies, decks, and exposed concrete surfaces
-
Stem walls and vertical surfaces requiring moisture barrier improvement
Product Details
SRS-4000 is a penetrating silicate/siliconate densifier and corrosion-mitigating treatment designed for hardened concrete. Its multi-phase chemistry penetrates deeply, reacts with free calcium, reduces permeability, and helps slow corrosion activity by improving concrete quality around embedded reinforcement. SRS-4000 is ideal for concrete affected by moisture, chlorides, carbonation, or early signs of deterioration.
When To Use
-
On chloride-contaminated concrete sur
-
On concrete surfaces with chloride contamination
-
When corrosion is present or suspected
-
On concrete showing signs of carbonation or early deterioration
Expected Performance
-
Reduces permeability
-
Decreases water-soluble chloride activity
-
Improves concrete durability and surface hardness
-
Reduces chemical reactivity
-
Helps restore a more alkaline environment (increases pH)
Features & Benefits
Penetrating Silicate/Siliconate Formula
Reacts chemically within the concrete to form a denser, less permeable surface matrix.
Improves Surface Strength & Durability
Demonstrated increases in compressive, flexural, and pull-off strength on treated substrates.
Reduces Chloride Ingress & Water Absorption
Lowers permeability, helping protect rebar from corrosion and preventing environmental deterioration.
Enhances Bond for Repairs & FRP Systems
Increases pull-off adhesion for coatings, overlays, and CFRP strengthening systems.
Breathable, Non-Film-Forming
Does not peel, flake, or delaminate. Allows moisture vapor transmission while reducing liquid absorption.
Suitable for Interior & Exterior Use
UV-stable chemistry maintains long-term performance in demanding environments.
Fast Application & Low Odor
Ideal for occupied buildings, industrial facilities, and weekend restoration projects.
