Below Grade Waterproofing: What Every Homeowner Should Know
For many homeowners in Laguna Beach and throughout Orange County, water intrusion is one of the most stressful and damaging issues they face. While decks and roofs get plenty of attention, the areas below ground—such as basements, foundations, and planters—are often overlooked until serious problems appear. That’s where below grade waterproofing comes in. It’s a preventative and corrective solution that protects your home from leaks, structural damage, and costly repairs.
What Does “Below Grade” Mean?
The term “below grade” refers to any part of your home or property that sits beneath the ground’s surface. This can include basements, foundations, retaining walls, and even planter boxes. Because these areas are in constant contact with soil and groundwater, they are especially vulnerable to leaks, cracks, and seepage. Without protection, water can make its way into your home, causing mold, mildew, and structural deterioration.
Why Below Grade Waterproofing Is Important
Soil naturally absorbs and holds moisture, especially during rainy seasons or after heavy irrigation. This moisture exerts hydrostatic pressure against the walls of your home’s foundation or retaining structures. Over time, even small amounts of pressure can force water through cracks, gaps, or porous concrete. Waterproofing acts as a barrier that keeps this water out, ensuring the structural stability of your home and maintaining a dry, healthy living environment.
Common Warning Signs of Water Intrusion
- Musty odors or dampness in basements or lower levels
- Visible cracks in foundation walls or floors
- White, chalky stains (efflorescence) appearing on walls
- Pooled water around planters or retaining walls
- Mold or mildew growth near below-ground areas
If you notice any of these signs, it’s important to take action quickly before the damage spreads.
Solutions for Below Grade Waterproofing
1. Professional Coatings and Sealants
High-quality coatings and membranes are applied to exterior walls and foundations to block water infiltration. Unlike DIY products, professional-grade coatings are designed to last and can withstand the constant pressure of groundwater.
2. Proper Drainage Systems
Waterproofing often includes ensuring proper drainage around your property. This may involve French drains, sump pumps, or grading adjustments to redirect water away from the foundation.
3. Planter Waterproofing
Planters built into patios or near structures are notorious for leaking into living spaces. Applying specialized waterproofing systems to planters prevents water from seeping into walls and flooring, preserving both your landscaping and your home.
The Benefits of Professional Waterproofing
Investing in expert below grade waterproofing ensures long-term protection for one of your home’s most vulnerable areas. Beyond preventing leaks, it helps preserve property value, reduces the risk of costly repairs, and provides peace of mind knowing your foundation and lower levels are secure.
