FULL DRAIN SYSTEMS

Many crawl spaces encounter flooding, standing water, muddy or heavy moisture conditions. These are all caused by excessive uncontrolled ground water in the crawl space. It is the ground water condition that must be addressed and this can be done by installing a full perimeter drain system.

A drain system not only keeps water from pooling or standing in your crawl space, but also keeps the ground water level below the grade of the crawl space, literally controlling and maintaining it below grade. A vapor barrier is then installed over the crawl space grade to hold down open earth moisture and vapors. Keep in mind, this system is designed to control ground water and it does so quite effectively.

To understand the difference between a drain system and encapsulation, read below, then check out our Encapsulation Systems section.

System and Warranty Comparisons and Differences

There are two types of drain systems to choose from:

Feature 10 Drain System

Installation and Components. The installation of the Feature 10 Drain System starts with hand digging a trench completely around the CST Feature 10 Drain System interior perimeter of the crawl space. A deep set sump basin is created at the base of the system. A 4-inch tile surrounded by filtration fabric webbing is then installed in the trench and set to drain ground water to the sump basin. A sump pump is installed in the sump basin.

Ground water that collects in the sump basin is discharged via the sump pump through an underground 1 1/2 inch PVC pipe to an in-ground water receptacle exterior to the crawl space. Placement of the receptacle is made in conjunction with the homeowner. The discharge could be taken to a natural low lying area in the yard or tied into a field tile system that might already be present.

As a final step, a 6-mil vapor barrier is placed over the crawl space grade to minimize open earth moisture.

Warranty. The Feature 10 Drain System comes with a 10 year warranty for no standing water in the crawl space and is transferable to the next property owner. The sump pump which is the engine of the system, is warranted by the pump's manufacturer's warranty of one year plus an additional year provided by The Crawl Space Team.

Cost Comparison. The Feature 10 Drain System is an economical solution for mold, moisture and water problems in the crawl space. Refer to our Encapsulation Systems section for encapsulation solutions.

CST Lifetime Drain System™

Installation and Components. A CST Lifetime Drain System ™ also includes a trench hand dug completely around the interior perimeter of the crawl space. A 4-inch tile with an aggregate-based filtration is installed in the trench. A deep set sump basin is created at the base of the system and a sump pump is installed within. Aggregate offers an advantage over filtration fabric webbing in that the potential for clogging is significantly reduced.

As with the Feature 10 Drain System, ground water collected in the sump basin is discharged via the sump pump through an underground 1 1/2 inch PVC pipe to an in-ground water receptacle exterior to the crawl space. Placement of the receptacle is made in conjunction with the homeowner. The discharge could be taken to a natural low lying area in the yard or tied into a field tile system that might already be present.

Finally, a 6-mil vapor barrier is placed over the crawl space grade to minimize open earth moisture.

Warranty. The CST Lifetime Drain System™ offers a lifetime warranty for no standing water in the crawl space and is transferable to the next property owner. The sump pump which is the engine of the system, is warranted by the pump's manufacturer's warranty of one year plus an additional year provided by The Crawl Space Team.

Cost Comparison. The CST Lifetime Drain System™ is a better solution for mold, moisture and water problems in your crawl space and, although it costs a little more than the Feature 10 Drain System, it offers a lifetime of worry-free service in your crawl space. Encapsulation is another product which may be installed as a separate solution or in combination with a drain system.
