First, the identities, because they matter: PRO Tek Concrete is manufactured by EverTek Construction Products Canada. AVENIQ (NanoSeal NB) distributes it in Atlantic Canada and provides product access and application support. EverTek owns the formulation; AVENIQ does not manufacture it and makes no independent claim about its development. Everything below separates what the manufacturer states, what third-party laboratory reports show, and what those things do not establish.
What the product is, per the manufacturer
EverTek's Technical Data Sheet describes PRO Tek as a clear, zero-VOC, water-based concrete fortifier: an alumina-modified reactive silicate treatment. The manufacturer positions it for both new (green) and existing (in-situ) concrete, applied as a liquid by low-pressure spray, reacting below the surface rather than forming a film.
The TDS states the product is a two-part system in current form (Part A plus an ACTIVATE catalyst, mixed before application), supplied in water-based form with a stated pH of about 11, specific gravity 1.134, and shelf life of two years from manufacture. Readers should treat the current TDS as governing, since EverTek has revised its documentation over time and the current controlled document is authoritative.
The manufacturer's described mechanism
Per the TDS, the treatment is designed to penetrate the near-surface matrix and react with available calcium hydroxide, converting some of it to additional calcium silicate hydrate (C-S-H), while the alumina modification promotes calcium aluminosilicate hydrate (C-A-S-H) and anion-binding AFm phases. The manufacturer presents a simplified reaction sequence on those lines.
Two honest notes on that mechanism. First, it is a manufacturer description, and this article presents it as such; it is not an independent verification. Second, the general chemistry involved (silicate reaction with calcium hydroxide to form C-S-H) is standard cementitious chemistry; the manufacturer's differentiation claim is the alumina modification and the C-A-S-H/AFm pathway, which would require the manufacturer's analytical package to evaluate in depth. The TDS notes that third-party testing of the treated material was performed by Brampton Materials Engineering (a P.Eng-led lab) in 2024, with reports available on request.
What the laboratory evidence shows
A set of manufacturer-published test reports covers treated-versus-untreated comparisons on specific specimens. The key results, each limited to the specimens tested:
- Deicer scaling (ASTM C672). Three treated and three untreated 12x12x3-inch slabs, 50 cycles with a calcium chloride solution: average cumulative mass loss about 0.82 lb/ft2 untreated versus about 0.05 lb/ft2 treated, with visual ratings averaging 4.3 versus 0.3.
- Water uptake (ATS BT005, Method B). Cores from a 50+ year old slab, sealed versus unsealed: mass increase 13.4 g untreated versus 1.8 g treated, tested by Brampton Materials Engineering (February 2025).
- Electrical indication (ASTM C1202). Cores from a 50+ year old slab: 3,094 coulombs (Moderate category) and 967 coulombs (Very Low category) on the two reported cores, tested May 2025.
- Abrasion (ASTM C779). Submitted garage specimens, CTLGroup (December 2021): 60-minute wear depth 0.113 in untreated versus 0.050 in treated.
- Petrographic package. ASTM C457 air void analysis with depth of penetration observations on 50+ year old slab cores.
Our test evidence article walks through each of these with method context and limitations, and is the place to check the numbers against their sources.
How this evidence should (and should not) be read
The pattern across all five reports is the same and worth internalizing: these are comparative laboratory measurements on defined specimens under defined methods. They support statements of the form "in the referenced laboratory specimens, the treated concrete showed X." They do not by themselves establish universal field performance, service-life extension, or equivalence to any other product. That is not a caveat unique to this product; it is the correct way to read any laboratory evidence, as our general test interpretation articles explain.
We also want to be explicit about what this overview does not claim. Generic published research about silicates, sodium silicate, or cement chemistry does not appear here as proof of PRO Tek performance, because category research does not establish product performance. Product statements in this article trace to EverTek's own documents or to the manufacturer-published third-party reports above.
Application essentials, per the TDS
Application is by low-pressure pump sprayer with a cone tip; the TDS prohibits atomization and HVLP/airless application. Surfaces must be clean, sound, and free of films; grease and silicone removal (EverTek positions its Greasy Clean degreaser for this) precedes application, and existing coatings must be removed. Current TDS mixing ratios use ACTIVATE catalyst per gallon, with different rates for green concrete, dense in-situ concrete, CMU, and precast; coverage varies with substrate porosity, and the TDS requires a suitability sample and mock-up before project pricing. Protect glass, aluminum, and painted surfaces from overspray; silicate chemistry etches glass and aluminum per the SDS.
What this product does not replace
The TDS and application guide are equally clear on limits, and our Where PRO Tek May Fit, and Where It Does Not article details them: no structural repair, no crack injection, no correction of settlement or drainage, no replacement of membranes where a membrane is specified, and no role as a substitute for proper curing practice where the specification requires a curing standard.
Where to verify everything
All product statements above trace to documents linked in the references, published by EverTek Canada (with third-party laboratory reports included in their resource set). AVENIQ provides access to the current controlled documents on request, and our test evidence walkthrough quotes the numbers with their contexts.
