Water Proofing the Crawl Space

In three short days, the framing crew has already finished the floor framing of the house. Granted, it's less than 900 SF, but it's terrific to be able to see such progress in a matter of days. 

The house isn't curved, just a fish-eye effect from shooting in pano. The garage to the far left, entry nook just to the right of the garage, and the rest of the house.

One of the largest concerns with any project, not just construction, is schedule. Timing is a pretty critical component of any big undertaking, and especially in construction where the lining up of different trades can become complicated, scheduling can get a little wild. Our original plan after wrapping up the concrete work at the base of the house, was to waterproof the crawlspace before moving on to framing. However, with all the building going on these days, especially in our area, the water proofer is crazy busy and needed more lead time than we originally thought. Without there being a confirmed start date on the waterproofing (both due to availability of labor and materials), our contractor suggested we push forward with the framing. With the taller than usual crawl space, we also had a little more flexibility in being able to lay down the waterproofing. 

So why are we waterproofing in the first place? Yes, we're in the middle of a historic drought, but believe it or not, there's actually still a lot of moisture in the ground. In addition to any future rains and water, the waterproofing will serve as a moisture barrier to help keep the crawl space dry and not to mention clean as the plastic creates a mat surface. 

Don't be fooled, this isn't a swimming pool. Nice and clean white plastic waterproofing membrane that will line the inside of the crawl space.

With our flood zone conditions and the existing grade being so low, we also figured that we'd try to maximize use of the crawl space, possibly as storage space. This membrane will not only keep our storage area dry, but it will much easier crawling around down there.

With the team working overtime (it is Saturday), they were able to lay down the membrane in the more abnormal part of the house, and a crew will come finish it off Monday. The area remaining uncovered is rectangular, so it should go down fairly quick. 

Now if you're really keen on detail, you might ask what happens to our flood vents? Once the membrane is completed throughout the inside of the crawl space, more finished detail work will have to be completed to cut out the flood vent holes and seal around the blocked areas where each vent will be placed. There are also four foundation posts in the crawl space that will have be wrapped to ensure moisture doesn't come up from the ground. 

Looking forward to sharing the finished crawlspace in the coming days.
