Crawlspace Drainage

Some examples of how water can enter a crawlspace as a result of:

In addition to making the crawlspace inaccessible, moisture can create high humidity throughout the house causing conditions such as:

Submerged heating ducts can create the ideal environment for mold growth and ground water pollutants which can then be transported into living spaces, contributing to allergies and other health problems.


Drainage solutions may require the following interior/exterior systems:

Controlling roof drain/downspout water is extremely important as this is often the major contributor to crawlspace drainage problems. We take the time during out bid appointments to determine if this is a contributing factor. Allowing roof water to flow through a crawlspace is never recommended and connecting a sump pump to a failed downspout system will only recycle it right back into a crawlspace. Proper drain piping & appropriate sizes of drain rock. A proper depth (ie. Gravity) of outlet or discharge line. Collection drainfields or trenches Sediment/catch basins Silt and debris filters Typically water can flow naturally by gravity or may be pumped if necessary. Without the above elemtns in place and operating properly, the system may not dry out the crawlspace completely. In addition, the extra strain can shorten the life of a pumping system.
