How to install a vapor barrier in the crawlspace

The best option to manage the damages at a crawlspace is closing down the vents. It helps in controlling the crawlspace moisture in better ways. This is done as some of the systems may not work in every space. For this reason, the use of a plastic vapour barrier is solicited.

  1. You need to create good drainage around the home. It will help the rainwater flow through underneath your house. The best practice in this regard is letting the soil slope away so that the crawlspace moisture is reduced.
  2. The vapour barrier will be used to cover the dirt crawlspace. The seams are also required to bind in tapes. You must ensure that all the debris over the spaces, especially the materials with sharp edges have been cleared. The grounds are also required to be cleared preferably using a garden rake
  3. The plastic vapour barrier is nowadays are more acoustically called a vapour diffusion barrier. This term offers more synchronization as plastic sheeting is not able to cover up or debar 100 percent of the moisture migration. These better help in slowing down the moisturizing process.
  4. The plastic sheets will be rolled out over the entire crawl space starting from one side. The sheets are cut in approximate sizes allowing 12 inches or more along the walls. The seams will seem to overlap by no less than 12 inches. The guarding will be secured with the use of the poly PVC tape.
  5. Water is seemed to intervene into the crawlspace through rainwater runoff or high water table in the nearby location. In such cases, you need to call a water remediation consultant company. These companies can bring up their own kit that would help in better prevention of the water vapour.
  6. There are cases where the water remediation consultant would dig a trench around the perimeter. Then a drain pipe is connected to the system. The pipe is covered with drain gravel and a sum pump is added that clears up the moisture going to be deposited in the crawlspace causing damage to the area.
  7. There are other practices too; these include the addition of roof gutters and downspouts. This will help in the reconfiguration of the earth grading that may work good in eliminating water or vapour from the crawlspace.
  8. The experience shows that water pools over the crawlspace through water supply pipes or drains pipes. If you are considering the installation of plastic vapour barrier there, rest ensure that the issue of water leakage from damaged pipes is appropriately been addressed.
  9. It is true that vapour barriers would help in preventing the seeping of moist water vapour throughout the crawling space. The position and action of such barriers can be bettered with cross ventilation in the spaces. Such ventilation prevents the trapping of any residual moisture in the crawlspace. While vapour barriers slow down the moisturizing process, cross-ventilation helps in complete eradication of the moisture.
