Building Process Video 9: Vapor Barrier and Sand

We continue our preslab preparations by adding a 6 mil vapor barrier with 2 inches of clean sand over our Type II underlayment. This is an additional step to typical underslab preparations. In past residential projects I have worked on, the 6 inch underlayment of Type II material or gravel was sufficient.

I would venture to say, based on my experience, that Type II or gravel is preferrable. As you will see in the construction video, sand can be difficult to work with because it does not compact as well as other material.

However, we MUST build to the approved blueprints. The architect called for sand and the building department agreed. While ease of installation is attractive to the contractor;the architect, engineers and city officials put their reputations behind approvals. If a component of construction would ever fail or reveal itself as substandard, the contractor's protection and the owner builder's protection is in having followed the approved working drawings and engineering.

Las Vegas Project

We will be continuing our Building Process Video Series for the next several months. The typical residential project takes 4-6 months, however, our Las Vegas Project is a 10,000 square foot custom home. It will take a total of 12 months to complete. While it may not be exactly what most owner builders are undertaking, it will demonstrate the building process that is common to all projects.

Remember, these videos are brief and fairly general. They are meant to familiarize owner builders with the building process. There is a lot of additional education and experience that an owner builder should seek out before starting their own project. As they say, knowledge is power.

Our goal is to show owner builders that a complicated, enormous custom home is built the in same way, using the same contractors, subcontractors, steps and materials, as the smaller, "simpler" projects that most of us plan to build. Of course, there will be unique challenges that may not apply to an individual's owner builder experience. They will, however, hopefully address another's issues.

I hope the videos are enjoyable and informative. I am still learning how to shoot and edit video. As time goes on, I will probably go back and re-edit some of the videos I have already done.
