Exterior Basement Waterproofing Do It Yourself

Exterior Basement Waterproofing: A Comprehensive DIY Guide

A damp or wet basement is an unpleasant and potentially hazardous problem for any homeowner. It can lead to a variety of issues, from musty odors and mold growth to structural damage. Fortunately, exterior basement waterproofing is a project that can often be tackled by do-it-yourselfers. This comprehensive guide will provide you with all the information you need to successfully waterproof your basement from the outside.

1. Inspect and Prepare the Exterior

The first step in exterior basement waterproofing is to inspect the exterior walls of your foundation. Look for any cracks, gaps, or other areas where water may be seeping in. Once you have identified the problem areas, you need to prepare the surface by removing any dirt, debris, or vegetation that may be blocking the way.

2. Install a Waterproofing Membrane

A waterproofing membrane is a sheet of material that is applied to the exterior of your foundation walls. It acts as a barrier to prevent water from penetrating the concrete. There are a variety of different types of waterproofing membranes available, but some of the most common include:

Asphalt-based membranes
Rubberized asphalt membranes
Polyvinyl chloride (PVC) membranes
Polyethylene membranes

The type of membrane you choose will depend on the specific needs of your project. Once you have selected a membrane, follow the manufacturer's instructions for installation.

3. Install Drainage Tile and Gravel

Once the waterproofing membrane is in place, you need to install drainage tile and gravel around the perimeter of your foundation. The drainage tile will collect any water that seeps through the membrane and direct it away from your home. The gravel will help to keep the drainage tile from becoming clogged.

To install the drainage tile, dig a trench around the perimeter of your foundation. The trench should be at least 6 inches wide and 12 inches deep. Place the drainage tile in the trench and cover it with gravel. The gravel should be at least 4 inches thick.

4. Backfill the Trench

Once the drainage tile and gravel are in place, you can backfill the trench. Use a compacted soil to fill the trench and tamp it down firmly. Be sure to slope the soil away from your house to help direct water away from the foundation.

5. Install a Sump Pump (Optional)

A sump pump is a device that is used to remove water from a basement. If your basement is prone to flooding, installing a sump pump can help to keep it dry. Sump pumps are available in a variety of sizes and capacities. The size of the sump pump you need will depend on the size of your basement and the amount of water that it is likely to accumulate.

To install a sump pump, dig a hole in the lowest part of your basement. The hole should be at least 18 inches deep and 12 inches wide. Place the sump pump in the hole and connect it to a discharge pipe. The discharge pipe should be directed away from your house.

Conclusion

Exterior basement waterproofing is a project that can be tackled by do-it-yourselfers. By following the steps outlined in this guide, you can successfully waterproof your basement and protect it from water damage.
