Basement Waterproofing Services in Indianapolis

A wet basement can result from one or more of these factors:

• Hydrostatic pressure – When the ground around your home becomes saturated after heavy rain, the water pushes against your foundation walls and floor.
• Wall cracks or gaps – Water can seep in through hairline cracks in poured concrete or along mortar joints in block walls.
• Floor-to-wall seam leaks – Water often enters where the basement floor meets the foundation wall.
• Poor grading or drainage – If the soil around your home slopes toward your foundation instead of away, rainwater naturally flows toward the basement.
• Clogged or missing gutters/downspouts – Without proper drainage, roof runoff can dump thousands of gallons of water directly against your foundation.

In Central Indiana and Cincinnati, clay-heavy soils hold water, making these issues worse.

Signs that you need professional waterproofing include:

• Water stains on walls or floors
• Damp or musty odors
• Visible mold or mildew
• Efflorescence (white, chalky residue) on walls
• Standing water after rain
• Rusting appliances or storage damage in the basement
• Peeling paint or deteriorating drywall.

Even if your basement only gets wet occasionally, the damage to your home’s structure, air quality, and value can be significant over time.

• Interior waterproofing manages water that has already entered by collecting it in a drainage system and pumping it away. This is the most common and cost-effective method for finished or usable basements
• Exterior waterproofing involves excavating around the foundation to apply a waterproof membrane and drainage system outside. While effective, it is more invasive and expensive.

Americrawl specializes in interior basement waterproofing, which provides long-term results without tearing up your yard.

We use the AkwaGard Basement Drainage System paired with a powerful sump pump. The process includes:

• Cutting a narrow trench along the basement’s perimeter
• Installing perforated drain tile with a filter to capture and channel water
• Connecting the system to a sump pump pit
• Installing a sealed sump pump system to expel water safely away from your home
• Finishing the floor for a clean look.

A sump pump is the heart of a waterproofing system. It sits inside a pit (basin) in your basement and automatically pumps collected water away from your home through a discharge pipe.

Without a sump pump, water collected in your drainage system would simply sit in the trench and cause problems.

The AkwaGard system is Americrawl’s professional-grade interior drainage solution. It is designed to:

• Capture water where the wall meets the floor
• Prevent clogging with a filter system
• Route water to the sump pump quickly
• Keep basements dry year-round

This system is installed with minimal disruption to your basement and comes with a warranty for long-term peace of mind.

Yes—when done properly. By eliminating water intrusion and lowering humidity, basement waterproofing removes the environment where mold thrives. We often pair waterproofing with CleanSpace wall liners or dehumidifiers for extra moisture control.

Pricing depends on:

• Basement size
• Extent of water intrusion
• Chosen drainage and sump pump system
• Whether additional features (like wall liners or battery backup pumps) are added.

In Central Indiana and Cincinnati, most projects range from a few thousand dollars to more for extensive systems. Americrawl provides free inspections and written estimates so you know the cost before work begins.

Most installations take one to two days, depending on your basement size and the complexity of the job. This includes trenching, system installation, sump pump setup, and clean-up.

While small cracks can be sealed temporarily with DIY products, true waterproofing requires a professional system. Improper installation can cause water to find new entry points or even increase pressure on your walls.

Yes. A dry basement:

• Prevents structural damage
• Improves indoor air quality
• Allows for safe storage or finished living space
• Reduces the risk of deal-breakers during a home inspection

Buyers see professional waterproofing (with a transferable warranty) as a strong selling point.

• Test your sump pump every 3–4 months
• Keep discharge lines free of debris and ice
• Check for power to the pump
• Have Americrawl perform an annual inspection for peak performance.

Yes—if paired with proper ventilation or dehumidification. While waterproofing stops water entry, it doesn’t remove existing moisture in the air. We often recommend a high-efficiency dehumidifier for complete control.
