15 Reasons to Use the CIVIL-TECT System

Proactive protection or effective remediation of reinforced concrete.

What is the CIVIL-TECT system, and why should you use it on reinforced concrete?

CIVIL-TECT involves a spray-applied penetrating corrosion protection treatment, that transforms free moisture in concrete to a hydrogel formation throughout the concrete matrix.

This is an amazing multi-benefit treatment for concrete, and here are some of the reasons for using it!

1Eliminates moisture migrationthe transport system for corrosion
Free moisture in concrete carries the contaminants that instigate and feed steel corrosion.
Hydrogel treatment immobilises this moisture … and the contaminants!
2Development of AAR-ASR, DEF & Sulphate Expansions are arrested
Immobilizing the moisture starves processes such as Alkali Reactivity (AAR&ASR), Delayed Ettringite Formation (DEF) & Sulphate
expansion that develop & damage reinforced concrete structures.
3Limits the availability of Oxygenwhich is the fuel of corrosion
Oxygen is one of the contaminants which fuels corrosion, and is carried into the concrete by moisture and moisture vapour. Arrest the supply of moisture-borne Oxygen = Halt corrosion and incipient anode development.
4Chloride ingress is preventedlong-term protection
Chlorides are a key contributor to the concrete degeneration process. Marine environments are particularly high in moisture-borne chlorides. Chloride ingress in new concrete is prevented by hydrogel treatment & further ingress into existing concrete is eliminated.
5Binds and purges existing chloridesthat aggravate corrosion
Chlorides are attracted into the hydrogel and are bound and or repositioned / purged. As a result there is no electrolyte available to assist the corrosion process.
This is an important point, and shows CIVIL-TECT’s particular value for existing at-risk structures.
6Increases Resistivity of concretedecreases galvanic activities
The hydrogel state has virtually no conductivity & cannot support galvanic activities = HIGH RESISTIVITY.
7Increases Steel Surface Passivationadding resistance to corrosion
Steel surface passivation is increased by the corrosion inhibitor component of the CIVIL-TECT treatment which consistently penetrates through the concrete to arrest corrosion of embedded reinforcing steel. Protects embedded steel in new concrete and arrests corrosion of existing deteriorated reinforced concrete structures.
8Enhances Concrete Strengthenhances hydration in new concrete
Hydrogels ensure new concrete completely hydrates, and reignites the hydration process of any unreacted cement in aged existing structures.
9Overcomes Incipient Anode Formationpreventing costly remedials
Concrete repairs and patching may often be followed by rapid deterioration of neighbouring concrete, caused by a process called Incipient Anode Formation.
Incipient Anode Formation is dependent on free moisture, oxygen availability and conductivity within the concrete. Hydrogel treatment eliminates these factors, effectively taking moisture out of the equation.
10Prevents Carbonation protects the concrete surface
The hydrogel eliminates the damage from gases such as carbon dioxide which dissolve to form corrosive acidic conditions within the concrete matrix.
11Waterborne solution and 100% VOC FreeCIVIL-TECT is a more environmentally friendly option for protecting concrete structures, compared to solvent based products. Hydrogel treatments are environmentally neutral enabling their safe use in sensitive zones.
12Proven25 Year Track Record
Proven to provide long-term protection on wharves, seawalls, bridges and structures exposed to chlorides from seawater and sea spray. The hydrogel has also been proven to efficiently protect car park structures against de-icing salt brines which are much more concentrated than seawater.

14Achieves economic savingsadds life value to high cost concrete assets
All of these factors mean that CIVIL-TECT is a one-off maintenance cost which is ideally applied early, before remedials become essential. Net Present Value (NPV) projections comparing CIVIL-TECT vs repetitive remedials show significant cost/benefits of the early expenditure of applying CIVIL-TECT System.
