I am in the process of building a new home with attached garrage and need some information on drainage considerations around the footers. I have already had my block & brick layed for the foundation. I wanted to know if i should run the drain on top of the footer or beside of the footer? i also wanted to know if i should run the 4" drain between the garage and the house(that would be below the concrete of the garage at the footer). Should I Seal the and install a drain around the outside of the garageat the footer?

Thanks for the Help!

Waterproof the foundation first.

You can install the drain beside the footer or on top. The waterproofing should cover the top of the footing and turn down the side if you plan to run it along the footing. You can cover the waterproofing with a protection board or drainage board before backfilling for a more effective system. If the drain and waterproofing extend at least is 11"-12" below the concrete it will function better and help prevent wicking.

I do not advise you to run the drain between the garage and the house if they are connected.

The International Residential Code from 2003 is now the model code for 45 of the US States.

It requires that drains be placed along side the footer and never above it.
