How Do I Waterproof an Elevator Pit?
We get a lot of questions about how you waterproof an elevator pit, so our Canada technical representative Gary Tench, the ‘elevator pit whisperer,’ thought it was time to write an article about best practices. Here’s what Gary had to say: There are two methods for waterproofing an elevator pit: from the outside, or from the inside. Waterproofing from the outside, also known as positive-side waterproofing, is the best method for protecting the concrete, the steel, and also the interior space. When you waterproof your elevator pits during pre-construction, you get the maximum performance out of your waterproofing system when…
Everything You’ve Ever Wanted to Know About Crawl Space Vapor Barriers
One of the realities of constructing and repairing commercial buildings is forever remaining aware of the dangers of moisture. Rotting wood, mold, chipped paint and more are all risks of water entering the building in areas where it’s not wanted. One good leak could cause tens of thousands of dollars of damage, and an area that is already susceptible could cause multiple rounds of damage if not dealt with effectively. So prevention is key to protecting buildings from the havoc moisture can wreak. But a rotted roof and a massive storm aren’t the only ways moisture can enter a commercial…
When the Weather Outside is Frightful
Building Envelope Building Materials Made for Low Temperatures If you’re specifying for winter-grade products, or you’re a contractor working outside in low temperatures, you’ll want to bookmark this article. W. R. MEADOWS has a portfolio of building envelope products – air barriers, vapor barriers, waterproofing membranes, accelerators, grout and form release agents — that ignore the cold weather to keep on keepin’ on, to borrow from Curtis Mayfield. Some of our products handle temperatures as low as -18° Celsius, or -62.6° Fahrenheit. Below is your convenient list of our winter-grade and low-temperature building envelope products, organized by the temperatures they…
How to Waterproof A Below-Grade Concrete Block Foundation: 7 Steps to Know Now
Concrete blocks have been used for many years as the alternative to a poured concrete foundation wall. Since concrete blocks are porous and concrete block foundations have numerous joints, they can be prone to water leaks. This is why waterproofing this substrate is so critical for the long-term performance of a concrete block foundation. On the positive side, they are strong, and have some thermal and sound insulation properties, which reduces energy usage. They are fire-resistant, and the addition of rebar adds structural strength to the foundation. Concrete block foundations are well suited to seismic areas, e.g., areas that are…
What Is a Concrete Expansion Joint?
When I was a kid, “Step on a crack, break your mama’s back” was echoed throughout the schoolyard, often the recitation as girls were jumping rope. Just to escalate everyone’s anxiety, some kid added a second idiom, “Step on a line, break your father’s spine.” These playground superstitions had us kids on high alert. Our otherwise carefree lives were disrupted by those horizontal sidewalk cracks. Until now, I never knew those sidewalk cracks had a name: concrete expansion joints. They also go by the name “control joints.” What’s the Point of a Concrete Expansion Joint? If concrete were elastic, contractors…
Why You Need a Pre-Applied Waterproofing Membrane on Your Vertical Application
When it comes to buildings, moisture is the enemy. Always. Moisture control is job one in construction planning. Most E&O insurance claims in the inspection industry involve moisture intrusion. Moisture is a top cause of building defects. Aside from the potential for your building’s degradation, health hazards like mold cause millions of dollars in medical bills annually. And black mold isn’t the only culprit. (In fact, there are many molds that are black – there’s no single type of black mold.) Many mold types can produce mycotoxins. Dallas is the top U.S. city for mold health issues, followed by Riverside-San…

What IS Negative Side Waterproofing?
Negative-side waterproofing is the act of applying waterproofing materials to the negative, or dry side, a.k.a. the interior side of your building’s foundation or wall. Building owners will often fill the maximum amount of property square footage possible with their new structure, leaving little room on the exterior of their structure’s property for the amount of excavating needed to do positive-side (or exterior) waterproofing. In another scenario, maybe you have a leak in a deep elevator pit. Perhaps it’s located in a downtown Toronto building where there is no way you can access that building’s exterior to waterproof it without…
How To Waterproof Outdoor Concrete Planter Boxes
Whether your property is a college campus, a corporate building, or Scrooge McDuck’s mansion, most elaborate landscaping designs will incorporate decorative concrete planters outside. And they need waterproofing. We’ve had enough web visitors inquiring about waterproofing outdoor planter boxes to trigger me writing an article, so this blog will explain why you need to waterproof outdoor concrete planters and how you can go about waterproofing your outdoor planters. 3 REASONS WHY YOU NEED TO WATERPROOF YOUR OUTDOOR CONCRETE PLANTERS Plants Can’t Soil Themselves. Unlike toddlers, plants cannot soil themselves, so gardeners need to maintain careful control over their plants’ soil…
Which Products Should I Use: Positive Side vs. Negative Side vs. Blindside Waterproofing
I’m sure someone has “an app for that,” but this article is your checklist to help you identify which waterproofing products to specify or apply to the positive, negative or blindside of a building envelope, because it can be confusing. Your first task will be essential: a full site inspection. This will determine some of your site concerns when you’re selecting your waterproofing system. Having this intelligence upfront enables you to identify the most durable long-term solution. Here are W. R. MEADOWS’ recommendations for below-grade waterproofing: POSITIVE SIDE: All forms of waterproofing products can be used on the positive side—sprayable…
When to Use a Fluid-Applied Air Barrier or a Sheet-Applied Air Barrier: How to Tell
Air barriers are your first line of defense in protecting your building from moisture. Why is moisture protection so important? You can find the answer in one of the most unsettling statistics to emerge in 2016 by the Australian Institute of Waterproofing: “…water leaks and the resulting damage from water leaks accounted for up to 80% of all building defects.” Eighty per cent! Indoor air quality (IAQ) issues from mold in remodeled and new buildings is estimated at 30% per FerroCanada. One in 50 homeowners will file an insurance claim for mold, and 93% of chronic sinus infections have been…
What’s the Difference Between Positive Side Waterproofing and Negative Side Waterproofing?
When junior architects or contractors are starting out, they get bombarded with new terms and a whole new language, so we want to make it our mission at W. R. MEADOWS to ensure everyone understands the most commonly used concrete, waterproofing, and construction terms. To that end, we recently were asked, “What’s the difference between positive-side and negative-side waterproofing?” Today’s blog serves to answer that question. Positive-Side Waterproofing The first thing to know is that positive-side waterproofing is on the outside of the structure, which is sometimes referred to as the “wet” side of the wall. This prevents any water…

What is Blindside Waterproofing?
You’ve heard of negative-side waterproofing. You’ve heard of positive-side waterproofing. So, what is “blindside” waterproofing? After reading this article, you can add ‘Blindside Waterproofing Authority’ to your LinkedIn profile in a New York minute. (Translation for our international readers: Really fast—like, Roadrunner fast.) The long short? Blindside waterproofing is a category of positive-side waterproofing. The difference? When you’re pouring a foundation in a dense urban area – think downtown Toronto, New York, London, or Rio de Janeiro – conventional waterproofing simply isn’t possible. Your project workflow will look more like this: Deploy a soil retention system that holds back the…
How Much Have Construction Costs Risen in 2022?
Construct Connect’s Chief Economist Alex Carrick recently did his quarterly Producer Price Index Series on the state of the U.S. construction industry’s material cost changes. The long short: his headline gives it away – “Spikes Everywhere.” Alex’s index tracks 15 materials. Of those 15, only one—prefabricated metal buildings—saw a 1.1% decrease. Thirteen of the 15 saw a double-digit percentage change increase in 2022 over the past year. The energy-related cost increases (+63.8% for diesel fuel, +61.5% for gasoline, and +36.9% for asphalt), the Russian-Ukraine war, and the supply chain disruptions all had a knock-on effect on building material costs. Since…
SUPPLY CHAIN UPDATES
In the topsy-turvy world of supply chain and logistics, there are some hints at the situation improving. The Covid-19 cases are on a downward trend. The ports are working faster than they have in the past year. There is a container backlog, but not nearly like last year. Anyone in manufacturing or farming has cast their watchful eye on the fluctuating oil prices, which are impacting everything from your food prices to airline travel to Vaseline. U.S. freight is more expensive and fuel surcharges are getting out of hand. Everything is dependent upon the war in Ukraine. If it ceases…
Are ALL Crystalline Waterproofing Systems Created EQUAL?
(Pro Tip: NO.) You may have heard the term “crystalline waterproofing,” also referred to as “integral waterproofing.” Concrete is naturally porous. Like death and taxes, it’s a fact of life — your concrete is going to absorb water, waterborne contaminants, and chemicals. The good news is, you have a defensive move. Whenever you need to defend your concrete from these normal intruders, and whenever positive-side sheet membrane waterproofing doesn’t cut it, that’s when crystalline waterproofing taps sheet membrane on the shoulder and says “It’s my turn to dance with this beautiful concrete.” Are there new innovations and improvements in cementitious…
What’s the Difference Between LIQUI-HARD and LIQUI-HARD ULTRA?
By: Dianne Carey Many architects, distributors, engineers and concrete contractors have asked us, “When should I specify/use LIQUI-HARD ULTRA? What’s the difference between LIQUI-HARD ULTRA and the original LIQUI-HARD?” How are they similar? Are there climates, locations, or geographies where one is an advantage over the other? Dianne Carey, director of technical services, has offered to help identify some technical features of the products, to help you identify the right product for your next concrete project. The Same… LIQUI-HARD and LIQUI-HARD ULTRA are clear, water-based, zero VOC, ready to use and can be used on interior and exterior applications. Both…
How to Choose the Right Concrete Pool Deck Sealer
If you’re like most homeowners with in-ground pools, you’re flummoxed by the endless flow of information for decorative concrete maintenance and concrete pool deck concrete sealants. Even your concrete—if it could talk—would admit it’s a lot to absorb. (FYI, if you’re ever doing an online search, concrete pool construction products are also called “construction liquids.”) Please note, this article refers only to concrete pool decks for inground pools, and not the wooden decks that tend to surround above-ground pools. Fortunately, DECK-O-SEAL’s Division Manager Jim Dill is not one to mince words (DECK-O-SEAL is a subsidiary of W. R. MEADOWS). Jim…
Why is Your Concrete Blotchy (and How to Fix it)
Have you ever walked past a home with discolored concrete in the driveway? It’s lighter here and darker there, creating a blotchy effect that you know couldn’t have been intentional. Looking at the chaotic design, you can’t help but wonder what went wrong,… and how you can avoid making a similar mistake with your own concrete projects in the future. Concrete discoloration is not a rare event Laying concrete isn’t an exact science, and there are a variety of factors that can contribute to concrete discoloration from the very beginning. These factors include: Variability in concrete mixtures The use of…
What Is the Difference Between Cold Fluid-Applied Waterproofing and Damp-Proofing?
The art of waterproofing started 13,000 years ago, developed to become the third trade after carpentry and masonry. As we became an agrarian society, farmers had to protect their grain from moisture and rotting during the cold months to prevent starvation. This Neolithic Era also brought boat-building and sea voyages into play to foment trading, so they devised a bitumen made from the surface of peat bogs, which wasn’t unlike the asphalt we use today. And then there were the Egyptians, whose Pyramids of Giza tombs were pristine despite the flooding of the nearby Nile River, so even in 3600…
IS MODULAR BUILDING THE MODEL-T ASSEMBLY MODEL FOR THE CONSTRUCTION INDUSTRY?
Seasoned engineer Blair Davies is the partner behind two modular construction businesses, METALOQ and Catalyst Offsite. Blair recently joined W. R. MEADOWS Podcast hosts Riley Rowan and Jason Davoodi to share some of his insights on the rapid-fire interest he is seeing from developers for modular building.

5 Reasons Your Building Needs a Below-Slab Vapor Barrier
There is much debate over the role and merit (as well as need) for vapor barriers within varied sects of the construction industry—however, there is a simple truth no matter what side of the discussion you happen to find yourself on. Ultimately, the systems under your building and above the concrete slab need protection, too, and simply leaving HVAC systems, wiring and plumbing, or the framework itself exposed offers far too much room for error—and seriously tempts Murphy’s Law. There is no sense in leaving the fate of your building up to chance, because let’s face it—damage can occur above…
ARCHITECTS and SPECIFIERS: How Will eCommerce and ESG Trends Impact Your Warehouse and DC Building Designs?
If you’ve been paying attention, you know the pandemic-driven eCommerce demands have amplified an already frenetic building trend: distribution centers (DCS), or warehouses. According to CBRE Research, every $1 billion in incremental eCommerce generates an additional 1.25 million sq. ft. of warehouse space demand for construction. Today’s existing warehouse space simply cannot meet industry requirements. In fact, the warehouse shortage is so drastic, UPS resorted to creating Ware2Go, a digital tool that helps shippers find on-demand warehouses. When Forbes magazine interviewed warehouse executives this year, Forbes found that warehouse building was their top priority for the next one to three…

How Do I Know If My Concrete Is Ready for a Penetrating Sealer?
Introducing the WATER DROPLET TEST The “water droplet test” is the industry standard for discerning if your concrete is ready for a penetrating sealer. We teach this simple method to distributors, contractors, and homeowners so they can visually identify the status of their concrete seal. Here’s the step-by-step application: STEP #1: Apply a water droplet to your concrete. When you want to know if your concrete needs a penetrating sealer, apply a small droplet of water to your concrete as seen here: STEP #2: Watch and wait. See if the water beads up, or if it absorbs into the…
UNO POWER: Why Should I Use a One-Step Concrete Cure and Penetrating Sealer Product?
You’ve been hearing about this single-step cure and penetrating sealer product on the construction sites for a while now, and you’re probably wondering, “Is this stuff cost-effective? Is it easy to use? What if it doesn’t last? Will my project benefit the most from a single-step cure and penetrating sealer product?” We get it. No one wants to be the guinea pig. That is why we were independent, third-party lab tested before we ever launched PENCURE OTC. PENCURE OTC demonstrated a similar chloride reduction and water absorption reduction rate as a 100% active silane placed on 28-day-old concrete. This blog will take…
How Do VOCs Affect My Construction Project?
If you’ve ever known that “new-car smell,” you’ve experienced VOCs. VOC is the acronym for “volatile organic compounds,” which specifiers and contractors seek to minimize in the products they construct with, especially since green building projects are mushrooming and environmental safety awareness is at an all-time high. In a new car, you can get exposed to off-gassing VOCs for up to six months after you buy it. (This is a great selling point for buying pre-certified vehicles). Studies have shown there are more than 60 VOCs detected in the average new car. VOCs are pervasive in our daily lives. It’s…
How to Achieve Less Stress and More Success
One Retired Contractor Teaches Small Business Owners His Secret to Early Retirement In the 1970s, AL LEVI and his two older brothers went to work with their father in their Long Island, New York contracting business. The brothers and their team of 70 performed plumbing, heating, air conditioning, and electrician services for Long Island outside of Manhattan. They serviced residential, commercial, and industrial accounts for a territory that was 115 miles, tip to tip. Raised in a family of serial entrepreneurs, AL’s grandfather owned a gas station in 1936. AL’s father started the contracting business that still thrives today. All…
THE SUPPLY CHAIN
Did America’s Covid-19 Shopping Spree Trigger Port Congestion? W. R. MEADOWS’ Supply Chain Manager Tony Spedale raised an interesting point during a recent internal discussion about California’s current port container ship congestion issue. It’s one many of us hadn’t factored in, and I thought it was worthwhile to share with you since we are all asking the big “WHY?” Here are Tony’s thoughts on the shipping delays and supply chain obstacles: “When Covid-19 hit, people were forced to stay home and get government stimulus, which was meant to be spent. The problem is, they spent their government stimulus money on…
Why Does My Pool Deck Joint Sealant Look Like Mushy Mastic? The 10-Minute Trick That Sets It Right Every Time
We’ve had contractors call us to ask why their joint sealant isn’t setting right or taking too long to set. The answer can be one of two things. Either the small can of activator is expired – for best outcomes, you will want to use DECK-O-SEAL within one year of our manufacturing date – or there’s a second reason: the installer didn’t use a stop watch set to 10 minutes. You may think that using a stop watch is overkill theater, but the truth is, a two-component joint sealant like our DECK-O-SEAL joint sealant is designed to be mixed for…

5 Tips to Protect Your Bottom Line
How the Construction Industry Can Sidestep Supply Chain Disruptions and Rising Builder Supply Costs How long will we remember the “Ever Given”? While history may relegate the Suez Canal-blocking ship’s name to fodder for future pub trivia, world economies and supply chains will be feeling the impact for months ahead. After all, the Ever Given blocked 350 vessels. Lloyd’s List estimated more than $9 billion worth of goods daily pass through that 120-mile waterway. When you multiply that $9 billion by the 6 days and 7 hours of canal obstruction, that’s a lot of balboas (Panama’s currency) for downstream companies…
