Company Milestones - W. R. Meadows
W. R. MEADOWS, INC.
THE INDUSTRY STANDARD BEARER SINCE THE EARLY 30s AND STILL GOING STRONG
A major product break through in the late 1940s established W. R. MEADOWS expertise in vapor and waterproofing products that has never been equaled. This innovative product was PREMOULDED MEMBRANE VAPOR SEAL with PLASMATIC CORE or "PMPC" as specifiers and users have come to call it. "PMPC" is a true vapor seal designed and proven for its unmatched underslab vapor and waterproofing capabilities. To this day, only PREMOULDED MEMBRANE VAPOR SEAL with PLASMATIC CORE offers the lowest WVT (Water Vapor Transmission) rating available-0.00 grains/sq. ft./hr. . . its the impermeable vapor seal. The product boasts a variety of other value-added features. It cuts "total-installed" costs, since "PMPC" can be laid directly over a compacted grade without requiring an expensive gravel or sand base. PREMOULDED MEMBRANE is as tough and as puncture/rupture proof as a vapor seal can be. Trundling wheelbarrows, foot traffic, aggregate impact, and an occasional pre-mix truck are all handled on-the-job without problems. Permanently sealed seams provide a bond that wont break when concrete expands, contracts, or the grade settles. "PMPC" wont rot or decay. Today, it meets and exceeds the maximum slab moisture transfer rate of 3 lbs./1,000 sq. ft./24 hrs. required by the flooring industry specifications.
RECOGNIZED BY BOTH PUBLIC
AND PRIVATE SECTOR SEALING CONTRACTORS AS Workers with wand and melter applicator applying HI-SPEC to highway joint.In the 1960s highway industry officials were
searching for a joint sealant that would meet and establish specification
criteria and perform satisfactorily under "real world" field conditions.
W. R. MEADOWS R & D met the challenge. The result was the development
of HI-SPEC Polymeric Hot-Applied Sealant.
A COMPLETE SOLVENT-BASE CURING & SEALING SYSTEM IS DEVELOPED AND EVOLVES
USER FRIENDLY, SOLVENT-BASE VOC COMPLIANT PRODUCTSAfter the U.S. EPA regulations took effect, W. R. MEADOWS replaced the pair with two high-performance, stand-alone products. CS-309-25 (formerly CS-309) and TIAH can be used individually for excellent results. Today, these popular solvent-base products are VOC compliant and comply with the U.S. EPA regulations. When properly applied, TIAH and CS-309-25 provide a long-lasting, non-yellowing, impermeable seal for moisture retention. Both products give concrete a hard, dense, high compressive strength, which provides excellent resilience against foot or vehicular traffic wearing. They also offer improved resistance to rain, sun, freezing temperatures, most acids and industrial chemicals, oil, grease, de-icing salts, cleaning agents (except aromatic solvents), caustics, construction abrasions, airborne soot, dust and other pollutants. MEADOWS PIONEERS LOW-SOLVENT, WATER-BASE PRODUCTS TO PREVENT ENVIRONMENTAL POLLUTION W. R. MEADOWS has been very concerned for nearly two decades about construction products that contribute to environmental pollution. The company was especially concerned with the high solvent content levels present in most construction liquids. As a manufacturer, W. R. MEADOWS decided to attack this problem using their own resources. The company’s product research and development capabilities were redirected and focused on an objective to develop concrete construction liquids that would not harm the atmosphere. A second objective, which goes hand-in-hand with the first, is to provide products designed to improve the worker’s environment. MEADOWS efforts paid off. The first of a broad line of true water-based products that would not harm the atmosphere emerged in the early 1980s. These newcomers, and those that followed, quickly became a product line tagged the “GREEN-LINE”®. VOCOMP®-20 and VOCOMP-25 Water-Base, Acrylic Curing and Sealing Compounds have been the cornerstone of the "GREEN LINE." They are renowned for their durable, excellent performance and high sheen characteristics. The “GREEN LINE” now numbers close to sixty products offering very low solvent contents. Many “GREEN LINE” products are so unique that their formulas are patented. The broad product line consists of concrete curing, sealing, hardening, cleaning, degreasing, anti-spalling, dust-proofing, and scaling protection compounds, concrete set accelerators, dampproofers, bonding agents, concrete form release agents, grouting, patching, resurfacing restoration products, evaporation retarders, concrete surface primers and bituminous surface treatment compounds. The water-base compounds perform even better than the solvent base products formerly used. Contractors prefer user-friendly "GREEN LINE" products because they’re so easy to mix and apply. Most products are designed for spray application and can be quickly cleaned up with soap and water while still wet. MEADOWS DIVERSIFIES WITH A PREMIUM LINE OF POOL DECK CONSTRUCTION PRODUCTS W. R. MEADOWS provides a premium-grade line
of pool deck construction products.

Early
in the construction liquids development program, MEADOWS’ R &
D people formulated a complete curing and sealing system involving two products:
CS-309™ Acrylic Curing and Sealing Compound and TIAH® Acrylic
Concrete Sealer. The original CS-309 and TIAH remained a popular system
for nearly 25 years, until the implementation of the Federal EPA Architectural
Coatings Rule Requirements took effect.
