With a 4.9-star rating from over 1,000 customers, full commercial licensing and insurance in both states, and a lifetime warranty on every installation, we are the commercial waterproofing specialists that Alabama and Tennessee property owners trust.
Signs Your Commercial Building Has a Water Intrusion Problem
Water intrusion in a commercial building is not always obvious — especially in the early stages. Watch for these warning signs:
- Visible water seeping through foundation walls or floor slabs
- Damp or wet spots on basement or below-grade walls
- Efflorescence — white mineral deposits left by evaporating water on concrete or block walls
- Musty or foul odors in basement or below-grade spaces
- Visible mold or mildew on walls, floors, ceiling tiles, or stored inventory
- Rust stains on walls or floors from corroding rebar or metal
- Peeling paint or blistering on basement walls
- Elevated humidity throughout the building
- Standing water in crawl spaces or below-grade mechanical rooms
- Deteriorating drywall, insulation, or floor coverings in below-grade spaces
If your commercial property is showing any of these signs, water intrusion is already occurring and the damage is growing. The Crack Guys offer free on-site commercial waterproofing inspections across all of Alabama and Tennessee.
What Causes Water Intrusion in Commercial Buildings?
Commercial buildings in Alabama and Tennessee face water intrusion from multiple directions. The most common causes include:
Hydrostatic pressure — Water-saturated soil exerts tremendous lateral and downward pressure against below-grade foundation walls and floor slabs. Alabama and Tennessee’s clay-heavy soils hold water far longer than sandy or loamy soils, making hydrostatic pressure one of the most persistent water intrusion drivers in our region.
Poor exterior drainage — When site grading directs water toward the building rather than away from it, water accumulates around the foundation and eventually finds its way inside through cracks, joints, and porous concrete.
Cracks in foundation walls or floor slabs — Even small cracks in concrete or block foundation walls provide a direct path for water to enter. As hydrostatic pressure builds, water is forced through even hairline cracks.
Failed waterproofing membranes — Many older commercial buildings have exterior waterproofing membranes that have degraded, cracked, or separated over time — leaving the foundation wall exposed to direct water contact.
Window wells and below-grade openings — Window wells, stairwells, and other below-grade openings that lack proper drainage or covers allow water to pool directly against the building and find entry points.
High water table — In areas with naturally high water tables, below-grade spaces are under constant upward pressure from groundwater. According to the United States Geological Survey, water tables in clay-rich soils across Alabama and Tennessee can rise significantly after heavy rainfall — dramatically increasing pressure on below-grade structures.
Our Commercial Waterproofing Services
The Crack Guys provide the full range of interior and exterior commercial waterproofing solutions:
Interior Drainage Systems — We install commercial-grade interior perimeter drainage systems along the base of below-grade walls to intercept water before it can pool on the floor. Water is channeled to a sump pump system and discharged away from the building.
Commercial Sump Pump Systems — We install heavy-duty commercial sump pump systems with battery backup to remove water from below-grade spaces reliably — even during power outages when storms are at their worst.
Foundation Wall Crack Repair — We seal and stabilize cracks in commercial foundation walls using epoxy injection and polyurethane foam to stop active water intrusion and restore wall integrity.
Exterior Waterproofing Membrane — For new construction or when exterior access is available, we apply waterproofing membranes to the exterior face of foundation walls to prevent water from reaching the concrete surface.
Crawl Space Encapsulation — Commercial crawl spaces are encapsulated with heavy-duty vapor barriers and sealed vents to eliminate ground moisture from entering the building. See our Commercial Crawl Space Repair page for full details.
Drainage Board Installation — We install drainage boards against exterior foundation walls to direct water downward and away from the foundation rather than allowing it to press directly against the wall.
Window Well Drains — We install drainage systems in below-grade window wells and stairwells to prevent water from pooling and entering the building through these vulnerable openings.
Dehumidification Systems — Commercial-grade dehumidifiers maintain appropriate humidity levels in below-grade spaces after waterproofing, preventing condensation and mold growth.
Interior vs. Exterior Commercial Waterproofing
Commercial waterproofing can be approached from the inside or the outside — and the right approach depends on your building’s specific conditions, the source of the water intrusion, and the accessibility of the affected areas.
Interior waterproofing manages water that has already entered or is entering the below-grade space by intercepting it at the base of the wall, channeling it to a sump system, and removing it before it can cause damage. Interior waterproofing is the most common approach for existing commercial buildings because it does not require excavation around the building’s perimeter.
Exterior waterproofing stops water before it reaches the foundation wall by applying membranes and drainage systems to the exterior face of the wall. It is the most comprehensive solution but requires excavation around the building’s perimeter — making it more practical for new construction or major renovation projects where exterior access is already available.
The Crack Guys assess your building’s specific water intrusion pattern and recommend the most effective and cost-efficient approach — or a combination of both — during your free inspection.
The Cost of Ignoring Commercial Water Intrusion
Water intrusion in a commercial building is never just a maintenance issue — it is a financial and liability issue. The longer water intrusion goes unaddressed, the more expensive the consequences become:
Structural damage — Water weakens concrete, corrodes rebar, and rots wood structural members over time. What begins as a minor seepage issue can eventually compromise the structural integrity of the building.
Mold and indoor air quality — Mold grows rapidly in wet below-grade spaces and spreads through the building’s air system. Tenant and employee health complaints, mold remediation costs, and potential legal liability all follow.
Inventory and equipment loss — Water intrusion in warehouses, storage areas, and mechanical rooms destroys inventory and damages equipment — creating losses far greater than the cost of waterproofing.
Insurance and liability exposure — Water damage claims and mold-related liability claims are among the most expensive commercial property insurance events. Proper waterproofing is the most effective risk management investment a commercial property owner can make.
Working Around Your Business Operations
Commercial waterproofing projects must be scheduled around your business operations — and The Crack Guys understand that. We work with property managers and building owners to develop repair schedules that minimize disruption to tenants, employees, and customers. Interior waterproofing projects are performed in below-grade spaces that can typically be cleared and secured without impacting above-grade operations. For larger or more complex projects, we develop phased repair plans that keep your business running throughout.

Frequently Asked Questions — Commercial Waterproofing
What is commercial waterproofing? Commercial waterproofing is the process of sealing and protecting a commercial building’s below-grade spaces — including basements, foundation walls, crawl spaces, and floor slabs — from water intrusion. Methods include interior drainage systems, sump pump installation, exterior waterproofing membranes, crack repair, and crawl space encapsulation.
What causes water intrusion in commercial buildings? The most common causes are hydrostatic pressure from water-saturated soil, poor exterior site drainage, cracks in foundation walls or floor slabs, failed waterproofing membranes, and high water tables. Alabama and Tennessee’s clay-heavy soils make hydrostatic pressure especially prevalent in our region.
What is the difference between interior and exterior waterproofing? Interior waterproofing intercepts water that has already entered or is entering the below-grade space and removes it before it causes damage. Exterior waterproofing stops water before it reaches the foundation wall. Interior waterproofing is more common for existing buildings — exterior waterproofing is more practical for new construction or major renovation projects.
Can you waterproof an active commercial building without shutting it down? Yes. Interior waterproofing is performed in below-grade spaces that can typically be secured without impacting above-grade operations. We develop repair schedules that minimize disruption to your tenants, employees, and customers.
Do you install commercial sump pump systems? Yes. We install heavy-duty commercial sump pump systems with battery backup for below-grade spaces of every size — keeping your building dry even during power outages.
What warranty do you offer on commercial waterproofing? Every commercial waterproofing installation is backed by a lifetime transferable warranty that stays with the building if it is sold.
Do you provide certificates of insurance for commercial waterproofing projects? Yes. We carry full general liability insurance and are fully licensed in Alabama and Tennessee. Certificates of insurance are available on request for all commercial projects.
