New Construction: Damp-proofing a Foundation Wall

One area where you can save a few dollars when building a home is to apply your own damp-proofing to your basements walls. This is an easy DIY project and could put a few dollars back into your pocket. Damp-proofing is different than waterproofing in that it is usually done in areas where the water table is not a problem. One of the best things you can do to protect your home from water is to make sure the grading around the house is done properly. Run off from weather or watering landscaping needs to run away from the house.


Step 1 – Preparation: Buy the tools and materials you need. Look for the list at the end of the article.

Step 2 – Determine Grade: You do not want to see the Asphalt Emulsion after the dirt has been backfilled against the house. Determine where the dirt is going to be backfilled against your house. Use a chalk line to snap a line to create a guide so you know where to stop rolling.

Step 3 – Dress: Before you start rolling put on some clothes you do not care about because this is a messy job. The tar will not come out of your clothes and you do not want to wash them because the tar will coat your washer and dryer.

Step 4 – Surface Preparation: Foundation may have tabs sticking out. Use a hammer to bust them off. Use a broom to clean off any miscellaneous debris. Surface must be clean, dry and sound.

Step 5 – First Coat: Open the 5 gal bucket and place the 5 gal screen in the Asphalt Emulsion bucket. The process is the same as painting but the material is often thicker. Try to apply an even coat and cover completely.

Step 6 – Last Coat: Make sure that all cracks, indents and holes are filled with emulsion.
