Protect Your Home’s Foundation with Expert Waterproofing Solutions

If you own a home in Alabama, water intrusion isn’t just inconvenient—it’s a serious risk to your home’s foundation, safety, and value. At Apex Foundation Repair and Waterproofing (AFW), we specialize in proven waterproofing solutions for basements and crawlspaces. From interior and exterior drainage systems to vapor barriers and sealants, we help keep water out—permanently. We follow all EPA recommendations and Alabama building codes to deliver lasting protection you can rely on.

Why Waterproofing Is Critical for Alabama Crawlspaces

Water intrusion is a serious threat to Alabama homes due to our wet climate and seasonal storms. Without proper waterproofing, you risk:

  • Mold Growth & Water Damage: Persistent water seepage fosters mold and mildew, damaging wood, insulation, and creating unhealthy air conditions.

  • Foundation Cracks & Settlement: Water pooling beneath or around your home can weaken your foundation, leading to cracks, shifts, and costly structural repairs.

  • Pest Infestations: Wet crawlspaces attract termites, ants, and rodents, all of which thrive in damp environments and can cause serious damage.

  • Air Quality Issues: Up to 50% of your home’s air can come from your crawlspace. Without waterproofing, that air may carry mold spores and contaminants.

  • Increased Energy Costs: Damp air makes your HVAC system work harder to regulate temperature and humidity, driving up your utility bills.

Crawlspace Waterproofing Solutions by AFW

Crawlspace Waterproofing

AFW provides expert crawlspace waterproofing to protect your home’s foundation from water intrusion and long-term damage.

  • Interior and exterior drainage systems redirect water away from the crawlspace.

  • Foundation walls and floors are sealed with industrial-grade waterproof coatings.

  • Sump pumps are installed to automatically remove any accumulated water.

  • Vapor barriers are used to block ground moisture and reduce humidity levels.

​

EZ Flow Drain Installation

EZ Flow is a modern, no-gravel drainage system designed to efficiently redirect water away from your crawlspace foundation—preventing flooding, pooling, and long-term moisture damage.

  • We install EZ Flow drains along interior or exterior foundation walls to capture and reroute water.

  • The system uses lightweight, gravel-free piping surrounded by a flowable aggregate for optimal drainage.

  • It's clog-resistant, low-maintenance, and ideal for wet Alabama soil conditions.

 

Little Giant Sump Pump

Even with drains and barriers in place, heavy rainfall or rising groundwater can overwhelm your crawlspace. AFW installs dependable Little Giant sump pumps to actively remove water before it becomes a problem.

  • Automatically pumps out excess water collected in drainage systems to keep your crawlspace dry.

  • Powerful, durable, and built for continuous performance in demanding conditions.

  • Includes backup options and sealed basins for reliable protection year-round.

Codes and Standards We Follow

At Apex Foundation Repair and Waterproofing, we don’t cut corners. Every waterproofing, drainage system, mitigation project is completed to the highest standard and complies with all federal and Alabama building requirements.

​

EPA Waterproofing Guidance

The EPA supports installing drainage systems and waterproof membranes that divert and block water intrusion. This includes foundation waterproofing membranes, sump pumps, and properly graded soil to keep water from accumulating near the foundation. Keeping the crawlspace or basement dry is key to preventing structural damage, mold growth, and indoor air quality issues.
​

Alabama Building Code & International Residential Code (IRC)

  • Alabama adheres to the 2015 IRC, which outlines requirements for keeping basements and crawlspaces free of standing water.

  • Crawlspaces must be protected by perimeter drains or other systems if located in flood-prone or high-moisture areas.

  • Waterproofing of foundation walls is required when groundwater conditions or hydrostatic pressure exist.

  • Drains must discharge water away from the foundation or into an approved sump system.
    Referenced Codes: IRC 2015 Sections R405, R406, R408

FEMA Guidelines

  • FEMA recommends sealed drainage systems (such as French or EZ-Flow drains) with sump pump discharge in high-risk flood zones or areas with poor soil drainage.

  • Foundation walls should be waterproofed—not just damp-proofed—when hydrostatic pressure or high water tables are present.

  • FEMA also advises elevating mechanicals and using backflow-prevention valves in vulnerable areas.
    Reference: FEMA Technical Bulletins TB-11 & TB-7

​

ASHRAE Standards

  • ASHRAE endorses a fully sealed and drained crawlspace or basement assembly in humid regions. This includes exterior foundation waterproofing, perimeter drains, and controlled discharge systems to prevent water accumulation and maintain building integrity.
