At Foundations First Northwest, we apply Basecrete coating to help protect foundation walls in crawl spaces and basements. This waterproofing skim coat creates a moisture barrier that reduces water intrusion and helps protect your home’s structure.
What Is Basecrete?
Basecrete is a cement-based coating applied directly to concrete foundation walls. It is mixed from two components, a liquid and a dry blend, to form a bonded protective layer.
You can think of Basecrete as a waterproof surface layer for your foundation. Instead of hanging on the wall like plastic, it adheres to the concrete, sealing porous areas and helping block moisture that can contribute to mold, odors, and deterioration.
Why Foundation Walls Need Protection
Foundation walls are in constant contact with damp soil, which means moisture pressure is always working against the concrete. Over time, moisture can seep through the surface and lead to musty smells, mold conditions, and damage to nearby wood framing or supports.
Concrete can absorb moisture, especially in wet climates. Basecrete helps by sealing the wall surface so moisture is less likely to pass through into the crawl space or basement. This supports a drier foundation area and a healthier home.
Where We Apply Basecrete
- Crawl Space Foundation Walls
Crawl space walls are often below grade and surrounded by consistently damp soil. Basecrete helps reduce moisture transfer through the wall and can help limit the musty conditions that are common in wet crawl spaces. Before application, we clean the walls and remove loose material so the coating bonds properly.
- Basement Stem Walls
Basecrete is also used on basement foundation walls to help prevent moisture problems. It works well on walls that show signs of dampness or minor surface wear by creating a more uniform, sealed surface.
The Basecrete Application Process
Our process focuses on proper prep, correct mixing, and consistent coverage.
Preparation
We remove loose paint, surface buildup, and debris, then clean and dampen the wall to the right level so the coating can bond.
Mixing
Basecrete is mixed to a consistent working texture using the liquid component and dry mix. The goal is a smooth blend that applies evenly and cures properly.
Application Methods
We can apply Basecrete three ways:
- Troweling: This method gives the thickest coverage at 1/8 inch per coat. We spread the mixture evenly across the wall using a trowel. This works well for rough surfaces.
- Spraying: With a sprayer, we apply thinner coats at 1/16 inch. This method covers large areas quickly and creates a smooth finish.
- Rolling: A roller applies 1/16 inch coats. We make two passes. One vertical, one horizontal. This ensures even coverage.
Benefits of Basecrete Coating
Foundation wall coating provides several advantages:
- Moisture Barrier: The coating blocks water from seeping through concrete pores. This keeps your crawl space or basement dry.
- Mold Prevention: By stopping moisture, Basecrete prevents the damp conditions where mold thrives. No moisture means no mold growth.
- Surface Protection: The coating protects concrete from deterioration caused by constant moisture exposure. This extends your foundation’s lifespan.
- Improved Air Quality: A dry foundation means better air quality in your home. You won’t deal with musty odors from damp concrete.
Post-Application Care
Basecrete needs time to cure. If you plan to paint over it later, allow proper curing time and follow surface prep requirements so the paint adheres correctly. For standard applications where the coating is left as-is, it cures naturally and does not require ongoing maintenance.
When to Choose Basecrete
Consider Basecrete coating if you notice:
- Dampness on foundation walls
- Musty smells from your crawl space
- White powder on walls (efflorescence)
- Minor concrete deterioration
- Moisture problems affecting air quality
This coating works as part of a complete waterproofing system. We often combine it with drainage solutions and vapor barriers for comprehensive moisture control.
Professional Application Matters
Basecrete works best when it is applied correctly. Proper results depend on surface preparation, accurate mixing, and consistent coverage. With over 40 years of experience, our crew knows how to prep foundation walls, mix the product to the right consistency, and apply it so it bonds well and performs as intended.
DIY applications often fail due to skipped prep steps or incorrect mixing, which can lead to poor bonding and uneven protection. Professional application helps ensure the coating provides reliable, long-term moisture resistance.
