HRM 714 Joins Our Waterproofing Lineup
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…

DUO-PAD at the Lehigh County Government Center.
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…

VOC Compliance Map Launched
As most of you know, varying VOC regulations across the U.S. can be a bit confusing. VOC regulations are sometimes ruled by the EPA, the state, or by local regulatory committees, and sometimes all of the above. And then, finding the product that fits your particular area can be confusing as well. Click Here to Open VOC Compliance Map At W. R. MEADOWS, we’ve spent countless hours developing products that meet the strict VOC regulations of your local area. We’ve worked closely with regulatory commissions such as the Ozone Transport Commission and the South Coast Air Quality Management District. To…
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…

W. R. Meadows Goes Solar … Again!
On March 15, 2011, W. R. Meadows commissioned its second solar-generating facility, with the startup of a 120kW photovoltaic solar farm, located at W. R. Meadows of Southern California in Pomona. The system consists of 1,270 roof-mounted, thin-film solar panels that have the combined capacity to drive 2,000 60-watt light bulbs. Each panel converts direct sunlight into clean, non-polluting electrical energy. It’s the same technology found in solar-powered pocket calculators, just on a larger scale. As electricity is generated by the solar panels, the DC current from the panels is converted into more conventional AC current, and is then fed back into the utility…
NFPA 285-2006
A fire test is a means of determining whether or not fire protection products meet minimum performance criteria as set out in a building code or other applicable legislation. There are a number of fire test methods that have been developed over the years. One of these that have become more recognized recently is the NFPA 285: “Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components.” This standard was developed by the National Fire Protection Agency (NFPA), an international non-profit organization established in 1896. In 1998, the NFPA developed this standard…
It’s our 85th anniversary. Let’s party.
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…

Air Barrier Developments
I just wanted to keep you informed of some developments that have happened throughout the US with regards to air barriers. There has been continuous work to try and promote air barrier usage throughout the country, and it seems that this has been successful. It has recently been finalized that air barriers are now included in the new ASHRAE 90.1 – 2010: Energy Standard for Buildings Except Low Rise Buildings. This is a standard that is referenced in several codes and documents, and before this revision, had not included any requirements for air barriers. The previous version of this standard…
