Proper drainage around House

This article is an excerpt from the book called “How to build a house” by “Larry Haun”. This gives a guidelines to keep the water away from the foundation.


We need water , We just don’t need it in our basements or under our floors, causing dampness, mold, and rot. We may not be able to hold back the Mississippi when it floods, but we can control most of the rainwater falls around our homes. Follow the guidelines below and you’ll stand a good chance of keeping water on the outside of your foundation.

  • Don’t build on the lowest part of the lot.
  • Seal all holes around the pipes that go through the concrete.
  • Install perforated drainpipes at the bottom of the concrete footings around the outside of the foundation.
  • Coat the foundation walls with a suitable damp-proofing or waterproofing treatment. Check with builders in your area or the local building department to find out which foundation coatings are recommended. Tar coatings are expensive but not as effective as more recently developed waterproofing treatments.
  • Compact loose fill as you backfill around the foundation, but be careful, because excessive compaction can damage masonry walls. Make sure that the finished grade (ground level) slopes away from the foundation. But remember that loose fill can settle. A finished grade that slopes away from the house may later slope toward the house should settling occur.
  • Use gutters and downspouts to manage high roof water runoff. Make sure you keep gutters unclogged and install down spouts to direct water away from the house.
  • Get advice from your building department. The time to protect your house from water infiltration is while you are building. Fixing a leaky basement or a damp crawl space after the house has been built can be very expensive.
