Lewis Construction Chooses Stego^® Wrap as Critical Component in Hi-Tech Fulfillment Center Project

After 35 years in the concrete construction industry, Steve Lewis has seen dramatic changes in best practices and even bigger leaps in technology.

But nothing may compare to the recent changes the industry has seen to meet the high demands of 21^st Century warehouse design: flatter floors, extended joints – anything to make fulfillment, logistics and robotics move more smoothly.

Avoid Costly Pitfalls in Concrete Slab Design

It's just a concrete floor. 

Historically designers, builders and occupants of industrial buildings may have whistled past their concrete slabs without considering the lack of under-slab water vapor protection they put into their slab design. That is, until they were confronted by one of a fearsome trio of very costly disasters.

7 Factors to Consider When it Comes to Under-Slab Vapor Barrier Placement

Vapor barrier thickness is a key attribute of a below-slab vapor barrier but it does not tell the whole story. Tune into this Stego IQ episode where Stego Technical Director Dan Marks provides some insight on all the key attributes that make up a high-performing under-slab vapor barrier which is puncture resistance, tensile strength, and most importantly permeance and longevity.

Stego IQ returns with the latest episode dispelling the myth about vapor barriers and slab curl. Dan Marks, Stego's Technical Director, returns to the screen to explain the short term slab curl effects with a vapor barrier as well as the long term effects of slab curl if you do not install a below slab vapor barrier.

For starters, is it Class I or Class 1?  Fun fact:  it’s actually Class I.  I get asked by both homeowners and contractors alike what a Class I vapor retarder is.  If you’ve been researching a DIY crawl space encapsulation project, it is possible you’ve stumbled across this reference as well.  In this blog post I’ll answer what a Class I vapor retarder is, but I’m also going to use this space to explain why a Class I vapor retarder, although referenced in code as a threshold, may not be satisfactory for your project.  To get you started on the right foot, we’ve made it easy for you to look-up the current version of code governing your jurisdiction.    

“Vapor retarder” is the term used to describe materials of varying types and classifications which impede the infiltration of water vapor into a structure. Often the term “vapor barrier” will be used interchangeably with the term “vapor retarder,” with no repercussions. But for under-slab applications, it is important to understand the distinctions between the two terms to avoid negative impacts on your project.
