If your basement becomes flooded each time that it rains, consider installing an exterior drain tile system. The pipe that is used will lead water away from your home and deposit into an area that will not be prone to flooding. Your home will be protected from damage each time that it rains. Keep reading to learn what you need to do to prepare your property for this system and how to complete the necessary steps. 

Use These Materials

  • rope and garden stakes (to mark the area that will be dug out)
  • large shovel
  • trench digger
  • measuring tape
  • landscape fabric
  • gravel
  • drainpipe
  • grass seed

If you need help looking for these materials or help with installation, talk with Rite-Way Waterproofing.

Have Your Property Surveyed And Receive Permission To Dig

Set up an appointment to have a surveyor assess your property and determine where the drain line needs to be installed. By doing so, you will be saving yourself a lot of hassle when it comes time to dig. Mark off the sections and keep a record of how deep you will need to dig. The drain line will be installed at an angle, making it necessary for the ground to gradually slope away from your home. Check your county's laws to see if you must obtain a permit before digging. If this is necessary, you will need to fill out a form and pay a small fee.

Clear The Land Where You Will Be Digging

Clear the area that you will be working by removing flowers, shrubs, debris, and rocks. If you have plants that you would like to salvage, dig them out by hand and move them to a different area. A pipe will be running under the ground and the roots from the plants can grow down deeply causing it to become blocked.

Dig The Trench

Lay plastic sheeting alongside the area that you will digging to place the dirt. When finished, you can drag the sheeting to another area and deposit the extra dirt. Dig out a trench with a large shovel. This will take a while to accomplish, but will save you money. The other alternative is to rent a trenching tool. To reserve one, check with a company that rents construction equipment.

Measure the depth of the trench as you dig to make sure that it matches up with the depth measurements that the surveyor provided you with. Smooth down the base of the trench and lay out a piece of landscape fabric over the surface. Measure the fabric and cut it so that it covers the bottom and walls of the trench. 

Add Gravel And The Pipe

Add a few inches of gravel along the base of the trench. Smooth it down with the back of your shovel so that it is even. Lay the drainpipe on top of the gravel. Make sure that any drainage holes that are on the pipe are facing upwards. Add more gravel to the trench, making sure that the drainpipe is covered completely. Fill in the rest of the hole with dirt. Pack the dirt down firmly. 

Plant Grass Seed

Plant grass seed in the area that you have just covered. It may take several weeks for it to begin growing well. Keep the area watered to assist with growth. Each time that it rains, the drainpipe will prevent water from seeping into your basement.
