Waterproofing The World Trade Center Fountains

Posted by Nick Leuci on Aug 9, 2018 10:00:00 AM

When designers started to plan what would become North America’s largest man-made waterfalls (World Trade Center Memorial -WTC) in New York City, they faced a number of challenges. One of the biggest concerns was how to contain vast quantities of water while preventing infiltration into underground structures.

Understanding Potable Water Approvals for Tank Coatings and Linings

Posted by Joe Borges on Jun 28, 2018 10:30:00 AM

Clean drinking water is often taken for granted. Drinking water standards are more stringent today to ensure that water is safe to drink. In 1988, NSF/ANSI 61 Drinking Water Systems Components – Health Effects standard was published. There are several laboratories certified by ANSI to test to this standard, including Underwriters Laboratories, the National Sanitation Foundation, and the Water Quality Association.

Common Waterproofing Mistakes are in the Details

Posted by Nick Leuci on Mar 28, 2018 1:01:00 PM

Waterproofing membranes, waterproofing coatings, and waterproof linings are terms that can be applied to a wide range of products.  They can be cold-applied liquid products, hot-applied products, peel-and-stick membranes or thermoplastic linings to name a few.  All these products provide a good barrier to water when used under proper circumstances.  So, why do so many installations leak?

The presence of leaks can almost always be attributed to poor attention to the waterproofing details, including:

Smart Tips For Cold Weather Coating Applications That Will Save You Time

Posted by Maribeth Taylor on Feb 8, 2018 11:30:00 AM

It’s common knowledge that colder temperatures can impact the curing of coatings. To achieve the optimum performance properties of the coating, special attention to the manufacturer’s application guidelines is needed.

Applications at colder temperatures, or below manufacturer’s recommendations, require experienced contractors who are familiar with CIM products. 

Smart tips for cold weather applications:

  • Plan ahead. Air and surface temperatures will affect the working and cure times of the coating.
  • Monitor temperatures. On cold, rainy, and windy days, the dew point and wind-chill, can account for moisture in the air as well as moisture formation on the substrate.
  • CIM coatings should be applied only when the substrate temperature is no less than 5°F above the dew point.

How to Dry Concrete Prior to a Coating Application

Posted by Jeff Raglani on Jan 15, 2018 1:30:00 AM

Coatings fail to bond to concrete for two reasons:   

  1. Lack of sufficient surface profile.
  2. Moisture in the concrete

Today, most coating manufacturers require concrete substrates to be dry (<5% moisture content) with low vapor transmission (< 3-5lbs per 1000 sq. ft./24 hours) before applying most types of membranes. This applies to both new and existing concrete substrates, although each may have its own set of moisture-related problems. For example, a 90-year-old poured-in-place partially buried concrete tank may face an entirely different set of circumstances from a newly constructed concrete slab with a steel tank mounted on it. Ultimately, the concrete needs to be dry prior to coating.
