Waterproofing a Block Wall from Outside

5 Proven Exterior Waterproofing Methods

Water damage is a homeowner's worst nightmare, especially in the Minneapolis-St. Paul area, where the climate can be particularly unforgiving. Basements, the lowest point in a home, are naturally susceptible to water intrusion. One of the most common culprits? Block walls. These walls, while sturdy, can become vulnerable to moisture over time. The solution? Waterproofing from the outside. Let's delve into the importance and process of this essential home maintenance task.

Why Waterproof Block Walls from the Outside?

1. Longevity: Block walls can deteriorate over time when exposed to prolonged moisture. This compromises the structural integrity of your home and reduces the lifespan of the wall itself. Waterproofing from the outside is a barrier, preventing water from seeping in and ensuring that your block walls last for years.
2. Health Concerns: Damp environments are breeding grounds for mold and mildew. These can lead to respiratory issues and allergies. By waterproofing your block walls from the outside, you eliminate the possibility of mold growth, ensuring a healthier living environment for you and your family.
3. Property Value: A home with a waterproofed basement is a valuable asset-potential buyers in the Minneapolis-St. Paul area is more likely to invest in a property protected against water damage, ensuring a higher resale value.

The Process of Waterproofing Block Walls from the Outside

1. Inspection: Before any waterproofing begins, it's crucial to inspect the block wall for any cracks or damage. Any issues should be addressed and repaired to ensure a smooth waterproofing process.
2. Excavation: The area around the block wall must be excavated to expose the wall thoroughly. This step is vital as it allows the entire wall to be waterproofed, from the base to the top.
3. Cleaning: Once exposed, the wall should be thoroughly cleaned to remove dirt, debris, or loose particles. This ensures that the waterproofing material adheres properly.
4. Application of Waterproofing Material: Several waterproofing materials are available, but a rubberized asphalt sealant is often recommended for block walls. This material is applied in a thick coat, ensuring that every inch of the block wall is covered. Ensuring that the sealant is applied evenly and without any gaps is essential.

5. Waterproof Sheet Membranes: After applying the sealant, a protective waterproof sheet membrane is applied over it. This membrane acts as a shield, protecting the sealant from any damage during the backfilling process.

6. Backfilling: The excavated area is then backfilled with soil. Ensuring the soil is adequately compacted to prevent future water accumulation is crucial.
7. Landscaping: Once the backfilling is complete, the area can be landscaped to its original state or redesigned per the homeowner's preference.
