What happens when water enters concrete?

It rarely stops at the surface.

Water moves through available pathways, carrying chlorides and other contaminants deep into the concrete matrix. From there, reinforcement corrosion can begin. As corrosion expands, it builds internal pressure that may lead to cracking, delamination, and spalling.

What starts as moisture intrusion can become a costly durability issue.

The good news: early protection helps reduce future deterioration and extend service life.

Where do you see water intrusion cause the most damage—parking decks, bridge structures, tanks, or building facades?

Most waterproofing arguments are not really about products.

They happen because the structure was never fully diagnosed before a system was chosen — and every party is then defending a decision made on incomplete information.
Five questions, answered honestly, remove most of that risk:

Which side is the water on? Is it pressure or vapour? Is the crack moving? What is already on the surface? What has already been tried?
None of these require laboratory equipment, four of them can be answered in a single site visit with a crack comparator, a spray bottle, a camera and the project history.

Which of the five is hardest to answer on your projects — and what do you do when the answer is simply unavailable? We read every comment on this one, share your thoughts!

A successful mock-up is not simply an area where the product was applied without difficulty.
It should represent the actual substrate, environmental conditions, preparation method, application sequence, and critical details expected during construction.

Before work begins, the team should agree on:
The question being evaluated
Representative test location
Baseline condition
Installation variables
Required documentation
Acceptance criteria
Observation period

Without these controls, the mock-up may demonstrate constructability while providing little evidence about anticipated performance.

Our first session is tomorrow!

Join us as we begin a practical comparison of commonly used concrete waterproofing approaches and Enzymatic TechCrete Technology (ETT).

We’ll explore how these technologies differ in surface preparation, application, compatibility, maintenance, and long-term performance—helping project teams ask the right questions before specifying a solution.

If you work in architecture, engineering, construction, or concrete asset management, we invite you to join the discussion.

For AIA members, this session qualifies for 1 AIA Learning Unit.

Each technology interacts with concrete differently, and those differences can affect surface preparation, application, compatibility, maintenance, and long-term performance.

This webinar series is designed to support a more informed conversation. We’ll compare commonly used waterproofing approaches with Enzymatic TechCrete Technology (ETT), discuss where each may fit, and examine the questions project teams should ask before specifying a solution.

If you work in architecture, engineering, construction, or concrete asset management, we invite you to join the discussion. You may join us through this link - https://hubs.ly/Q04t51450 .

Early detection can create an important opportunity to slow the progression of alkali-silica reaction (ASR).

After early signs of ASR-related deterioration were identified on an Iowa Department of Transportation bridge built in 2011, the team took a proactive approach to protecting the concrete bridge deck.

BridgeDECK does not reverse ASR. However, by reducing water intrusion into the concrete, it can help limit the moisture that contributes to continued ASR expansion while also protecting the deck from other ingress-related deterioration.

This project highlights the value of identifying deterioration early when preservation strategies may still help extend service life and reduce the need for more disruptive repairs.

Seeing early signs of ASR or moisture-related deterioration on a bridge deck? Contact our team to discuss the condition and explore whether a proactive waterproofing strategy may support your preservation plan.

A clear specification should leave little room for interpretation, not only during bidding and installation, but also during inspection. The goal is not necessarily to add more language but to create shared expectations that the entire project team can understand, inspect, and document.

What information have you found most important for keeping specifications clear and enforceable in the field?

Concrete rehabilitation can require extensive demolition, reinforcement treatment, patching, traffic control, access, and operational disruption. Once that investment has been made, the next question is how to reduce renewed exposure to the conditions that contributed to the original deterioration.

The project team may benefit from reviewing:

Moisture and contaminant pathways
Cracks and joints around the repair
The condition of adjacent concrete
Compatibility between repair and protection materials
Drainage and water management
Future inspection and maintenance needs

Protection does not replace sound repair engineering. It can complement it by helping preserve the restored concrete and reduce continued ingress.

How do you evaluate cracks in concrete?

Let’s make this practical: if a crack looks dry during inspection, would you assume it’s harmless? Not always. A dry crack can still allow water ingress when rainfall, temperature, groundwater levels, or service conditions change. For non-structural cracks, one dry-weather inspection rarely tells the full story. When assessing cracks, consider:
• Is the crack moving over time?
• What has the exposure history been?
• Are seasonal changes affecting it?
• Are there visible signs of past leakage?

Once structural concerns have been ruled out, Enzymatic TechCrete Technology (ETT) can be considered as part of a waterproofing strategy to help treat general cracking and stop recurring water intrusion in concrete.

What do you usually look for first when evaluating a crack? If you have recent photos of visible cracks, share them in the comments.

Dust, laitances, curing compounds, sealers, oils, weak surface paste, and previous coatings can restrict pe*******on, compromise adhesion, alter material consumption, or prevent the specified technology from interacting properly with the concrete.

A surface may appear clean and still be unsuitable for treatment. Preparation requirements should therefore reflect both the substrate’s actual condition and the functional needs of the selected system. Depending on the technology, verification may include multiple variables.

Generic requirements such as “clean and sound” leave too much room for interpretation unless the specification also defines how substrate readiness will be tested, documented, and accepted.
The application begins long before the product reaches the surface. It begins with establishing the conditions the system needs to perform.

How about you, does your surface-preparation specification define measurable acceptance criteria—or rely primarily on visual approval?
