Our OTC line of products are formulated to conform to VOC regulations in areas governed by more restrictive regulations, while keeping your concrete surfaces beautiful and durable. Our OTC Product Application Guidelines video is a great way to inform yourself on the new steps to applying these VOC-compliant products. We’ve also recently created a Spanish version of the video available. Click here to view the Spanish version of the video.

We recently introduced HRM 714, a hot-applied rubberized asphalt membrane used to waterproof concrete, into our waterproofing lineup. HRM 714 is a 100% solids blend of asphalts, synthetic rubber polymers, and filler formulated to provide toughness with flexibility and low moisture vapor permeance. It is ideal for horizontal and vertical applications for waterproofing bridges, parking lots, plazas, or promenade decks; tunnels; pedestrian concourse; and other similar types of construction where a monolithic waterproofing membrane is desirable. Poured at a recommended temperature of 360° to 400° F, HRM 714 is applied by spreading the product with a squeegee to a minimum…

We recently introduced EG-96 HP as a deep grouting solution for industrial projects. EG-96 HP is a three component, 100% solids, VOC and BGE free, epoxy resin system designed for deep grouting of large machine bases, setting level wedges, and sole plates requiring precision alignment under dynamic and vibratory load conditions. The grout is ideal for use in industrial projects including crane rail and wind turbine base grouting and support of chemical tanks, vessels, and rotating equipment. Some features and benefits of EG-96 HP include: High early strength Excellent creep resistance Thermal stability during application Excellent adhesion to concrete and…

CEM-KOTE FLEX ST is a highly flexible, fiber-reinforced, breathable, cementitious slurry, consisting of dry Component A and liquid Component B.  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…

As you may have noticed, W. R. MEADOWS has started using Quick Response codes (QR codes) on its labels, brochures, and other marketing material. While QR codes may look confusing, they continue to grow in popularity and widespread use, given the increasing popularity of smartphones. When you scan or read a QR code with your iPhone, Android or Blackberry, you can link to websites, YouTube videos, or display a user’s contact information. QR codes can be used in numerous applications: Labels: QR codes can display product data sheets from our website (which have links to MSDS, guide specs, videos, etc).…

W. R. MEADOWS was proud to take part in this solar panel project at the Lehigh County Government Center in Allentown, PA.  The engineer, Atlantic Energy Concepts, consulted with us about what product would be appropriate for this application. Atlantic Energy Concepts had several projects involving a variety of roofing materials – including EPDM, bituminous, and silver coating – in which they were installing solar panels on top of metal trays that are held to the roof by the weight of cinder blocks. They wanted to put the trays on top of a protective pad in order to prevent damage…

We’re proud to partner with our friends at AEC Daily to offer a new online continuing education course.  This course, Effective Waterproofing, provides an overview of effective concrete waterproofing technologies and how they improve the durability and lifespan of structures and includes discussions on water penetration, system selection, membrane protection, and cementitious waterproofing. The online course earns continuing education from a number of different groups, including the American Institute of Architects (AIA).  It’s also a great way to learn about waterproofing in general. Here is the direct link to the Effective Waterproofing course.  You will need to register for AEC…

This document has been created as an addendum to our Air-Shield technical data sheets to provide some additional information regarding the application of transition membranes for rough openings, such as windows and doors. To remain current in the industry and provide our customers with an economical and user-friendly air barrier assembly, we would like to provide two different application procedures to address the use of transition membranes. The first is the use of our Air-Shield self-adhesive membrane as we have always used, and the second is the use of our Air-Shield LMP vapor permeable fluid-applied membrane. Either of these systems…

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…

W. R. Meadows is always happy to offer AIA-accredited presentations to help architects earn learning units and keep up on the latest construction technology.  We’re now happy to offer a new presentation on cementitious waterproofing.  Our experience with the concrete waterproofing industry covers over 70 years, and we’re eager to share what we’ve learned with the architectural community.  Here’s an overview on our cementitious waterproofing presentation: This course provides an overview of the composition of concrete and some of the inherent problems relating to concrete deterioration as a result of water penetration, as well as various cementitious waterproofing materials, including crystalline…

Congratulations to our own Dianne Carey, director of technical services, as she recently passed her CSI (Construction Specifications Institute) Certification Program.  Dianne is now a Construction Documents Technologist (CDT).  The significant effort she has expended to acquire the knowledge necessary to pass a CSI examination puts her in an elite group of construction professionals.  By being CSI-certified, Dianne has developed a conceptual understanding of the entire construction process, and earned concrete skills in construction documentation development and administration, specification writing and enforcement, product research and sourcing, and communication with the design and contracting teams.  Congratulations, Dianne, on this noteworthy achievement.

Congrats to our own Russ Snow for being designated the first Construction Specifications Practioner (CSP) in the industry. The objectives of the CSP are to set standards and a high quality of practice for specification writers through prescribed qualifications, courses, and a demonstrated level of competence and ethical practices, as well as to provide a program for continuing improvement of specification writer skills and professional development and to establish a body of knowledge and standard of conduct for specification writers. This designation is one that has been in development within Construction Specifications Canada (CSC) for a few years and recently has been released. …

How are we celebrating?  Nothing fancy – just providing our clients with quality, integrity, and service, which have been our core values since our founding in 1926. We’ve come a long way since our founding.  The first product sold by W. R. Meadows was Asphalt Expansion Joint, a product we still sell today.  The company first started with manufacturing these expansion joint products, but we gradually increased our line to including curing and sealing compounds, building envelope products, and concrete restoration.  Pretty much, if you’re involved with concrete construction, we have a product for you. We’re also proud to have expanded…

Our product spotlight this month is on ADI-CON CW PLUS, a new product added to the extensive line of concrete waterproofing materials from W. R. Meadows. ADI-CON CW PLUS is a dry, free-flowing powder containing a blend of inorganic and organic chemicals, a small amount of sand, and silica-based materials. The reactive materials react with lime generated by the hydration reaction of cement and plug the capillary porosity, making concrete watertight under water head pressure. ADI-CON CW PLUS, when mixed into concrete, works well in foundation waterproofing and all concrete waterproofing applications. ADI-CON CW PLUS is an integral waterproofing admixture…
