The 12mil fiber-reinforced encapsulation is a type of crawlspace waterproofing system that is designed to correct and prevent water intrusion into a home's crawlspace. The encapsulation involves the use of a thick layer of reinforced polyethylene plastic sheeting that is installed over the walls, floors and pillars of the crawlspace.

The polyethylene sheeting is made of high-density polyethylene (HDPE) material that is strong and durable. The reinforcement comes in the form of millions of tiny fibers that are mixed into the polyethylene during the manufacturing process. These fibers add to the strength and durability of the material, making it resistant to tears, punctures, and other types of damage.

The encapsulation process typically involves several steps. First, any existing water or moisture is removed from the crawlspace walls and floors using our SITEDRAIN™ Neverfail Drainage System.  Secondly, the walls, floors and pillars are cleaned and prepared for the installation of the encapsulation system. Thirdly, all vents are sealed off.  Then, the polyethylene sheeting is installed over the walls, floors, vents and pillars.

Once the encapsulation system is in place, it creates a barrier between the crawlspace and the outside environment, preventing water and moisture from seeping into the space. The system also helps to regulate humidity levels in the crawlspace, which can help to prevent the growth of mold and mildew.

Overall, the 12mil fiber-reinforced encapsulation system is a highly effective and durable solution for crawlspace waterproofing and moisture control. It is a popular choice among homeowners and contractors due to its strength, durability, and long-lasting performance.


If you’re seeing any of the typical warning signs we list below, contact our team for a crawlspace inspection .

  • Moisture and Mildew Odors. If you detect a damp, musty odor in your home, it may well be emanating from the crawlspace. Besides being an annoyance, it’s also a potential health hazard.

  • Cracks on Drywall. When you see cracks forming on your drywall, their cause – or partial cause – could be sags developing in the crawlspace.

  • Uneven Flooring. Sagging floors are a sign of a weakening foundation. In addition, it may indicate that there’s an issue in crawlspace.  Call 423-883-4521 for a free estimate.
