Our Hawkesbury District & General Hospital (HGH) case study describes the problem and solution when the new additions to the structure were designed and built. This case study is a great way to learn more about how W. R. Meadows products were used to waterproof this large project. When the Hawkesbury District & General Hospital (HGH) decided to build two large additions to its community hospital in Hawkesbury, Ontario, Canada, construction officials knew there was a big problem to solve. Below ground level was a substrate composed of solid rock with gravel on top. That meant there was no…

Available now: Air-Shield TMP installation guidelines
Another in the W. R. Meadows line of Air-Shield products is our Air-Shield TMP, a water-based air/liquid moisture barrier that cures to form a tough, seamless, elastomeric membrane. Air-Shield TMP exhibits excellent resistance to air leakage. Furthermore, when properly applied as a drainage plane, it prohibits liquid water intrusion into the substrate. Air-Shield TMP is formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it. It may be applied to most common surfaces and integrated into various wall systems. Air-Shield TMP is versatile in that it is suitable for both new construction and retrofit…

Read our new Airbus case study!
The first-ever Airbus manufacturing facility in the U.S. was waterproofed using products from W. R. Meadows. We’re proud of this fact and our newest case study relays the facts in this unique application. One of the biggest hurdles to overcome was the fact that the site of this project, Mobile, Alabama, is the rainiest city in the U.S. Obviously, high quality waterproofing materials were needed to ensure that moisture did not intrude the structure and the architect and contractor team decided upon our Precon, Perminator, and Mel-Drain products. As the September 2015 grand opening of the Airbus plant – which…
Hot-Weather Guideline: Repair Mortars and Non-Shrink Grouts
As hot weather hits, constructors need to adapt to the hot-weather conditions that my impact the installation of construction materials. Many materials act differently in hot weather as to cold, and certain precautions and steps should be taken to ensure a successful installation. At W. R. Meadows, many of our products are impacted by climatic conditions and concrete repair products, in particular, must be applied carefully in the summer months. To make this process easier, and to help educate and inform our clients, we’ve developed a number of installation guidelines to help make installations error-free. Our hot-weather guideline for our…

Pourthane SL at the Panama Airport
Our Pourthane SL joint sealant continues to be a great material for all concrete joint sealant applications. We recently traveled to Panama to see the product in action. The product has continued to be a fantastic material to use in all types of joint sealant applications. This particular project was 15,000 linear meters and also featured our Kool-Rod backer rod. We’re excited about our Pourthane SL product and equally excited to work with our Latin American partners. View the photo gallery below to see the product in action.

CEM-KOTE FLEX ST is designed for positive and negative waterproofing of concrete structures in new construction and restoration. It is suitable for water and wastewater tanks, secondary containment structures, tunnels, concrete slabs, balconies and…
Applications Guidelines for Our OTC Line
As VOC regulations have changed and become more restrictive, product manufacturers have had to rethink formulation of solvent-based concrete curing and sealing compounds. Solvents that were typically used in the past, must now be partially or totally replaced with solvents that are considered VOC-exempt. Incorporation of these VOC-exempt solvents into formulas has altered the physical properties and performance features that you may have been used to with traditional formulas from the past. VOC-exempt solvents have very low flash points, producing finished products that are extremely flammable. Read and follow ALL literature, MSDS, and label environmental health, safety and handling instructions/precautions…
Blotchy Concrete
Why does my concrete look “blotchy” (inconsistent gloss) after applying a W. R. MEADOWS concrete curing and sealing compound or concrete sealer? You’ve just sealed your concrete hardscape and it appears “blotchy” or it isn’t “glossy” over the entire slab. Typically, when we see a floor or exterior slab that is blotchy or not uniform in gloss, it’s caused by; (or a combination of the issues listed below): Poor sealer application technique. Not enough sealer applied. Varying absorption rates of the concrete (some areas are by concrete’s nature more porous than others) If you were to look at a concrete…
