Effects of High Water Tables on Your Basement


Every structure that enters the ground should be waterproofed.  If the structure is located in a place with a high water table, waterproofing is not only necessary, but it must be of excellent quality. 

What is a water table? The water table is the point between the two zones at which the ground becomes completely saturated. It forms the upper limit of deposits of groundwater, and can go up or down based on a number of factors.  Every time it rains, for example, water trickles down through layers of soil and raises its water table. Runoff from lakes, rivers, and streams also contribute, along with melting snow. The rock around the water table must be porous so that it can be saturated with water. Impermeable rock such as granite, cannot collect water.

The level of a water table can fluctuate depending upon environmental conditions as well. Seasonal dryness and tidal changes, as well as human interaction can also have an impact. A drought for example, can cause it to drop significantly, and heavy rains can cause it to raise.

Many wet basement issues occur when the structure is located in a place with a high water table.  A high water increases hydrostatic pressure on the floor and walls of your basement, making it susceptible to leaks. If left like this, it can even lead to serious foundation issues.

Try not to worry too much though! Often times the solution is simpler than it seems and even if it’s not, we’re here to help.  You can still have a dry basement and a healthy foundation if you live in an area with a high water table!

Helpful Tips

Waterproof your basement walls. There are many ways to do this and the approach depends on the needs of the space, but this is essential in keeping the water out.

Install a draining system.  This will provide relief to the hydrostatic pressure building up around your foundation.  Drain systems can be both internal or external, but a combination of both is usually ideal. Yard drainage systems, french drains and interior/exterior drain tiles are just a few of the options.

Install a reliable (preferably high volume) sump-pump system with a battery back up. Sump-pumps are relatively inexpensive but can be very beneficial in the long-run.

Call a professional!  Have someone take a look at your basement and discuss the issues with you. Many homeowners think that these issues are DIY projects but this can lead to bigger problems. Do not play with the integrity of your foundation and the health of your family!
