Common Problems

Keeping your basement from flooding is no easy task. Find out what issues your basement might be susceptible to.

Water Intrusion

Heavy rainfall or melting snow can cause basement flooding which result in weakness in the ground beneath your foundation. Foundation sinking, bowing basement walls, and other structural damage can occur as the supporting ground softens. In the process, your’re left with an ideal environment for the growth of mold and mildew.

Biological Growth

Humidity in the soil and air releases destructive water vapor, debris, contaminates, and pollen. This damp air carries mold spores and musty odors, providing the perfect environment for insects and other pests, as well as wood rot. These issues affect your home’s structure and the quality of air in your living spaces.

Bowed Or Leaning Walls

All soil can expand and contract after a heavy rain or drought. When the soil supporting your foundation changes, it can cause your home to shift. During wet weather, water saturates surrounding soil, causing it to swell and push against subterranean walls. This lateral pressure can make basement walls bulge or leak, causing a wet and smelly basement.

How Do I Fix It?

Acculevel installs interior drainage and sump systems that redirect water before it can pressurize your basement. For many homes, our recommended solution is the Fast Track perimeter drainage system paired with a sump pump.

Redirection With Fast Track

Fast Track is a low-profile interior drainage channel set on or alongside the footing at the cove joint (where the wall meets the floor). It collects water from wall seepage, the cove joint, and under-slab migration, then routes it to a sump pump for safe discharge.

How Fast Track Is Installed

  • A narrow strip of concrete is cut along the perimeter to expose the top of the footing.
  • If the foundation is a block, small weep holes are drilled in the bottom course to relieve trapped water.
  • Pre-formed Fast Track sections are placed on/along the footing and connected to the sump basin; a wall liner or dimple board is integrated so moisture drains straight into the channel.
  • The trench is capped with new concrete flush to the floor, the sump lid is sealed, and the pump and discharge are tested.

Water Removal with Sump Pump

All Acculevel waterproofing systems drain into a top-of-the-line sump pump system and include safeguards against power outgages and pump failures. It is extremely important to have a second battery-operated pump in the sump liner in case of mechanical or power failure. Acculevel battery back ups are dependable and flexible.

Flooded Basement Repair FAQs

What’s causing my basement to flood in this area?

Clay soils and heavy storms create hydrostatic pressure. Water enters at the floor cove joint, wall cracks, and slab cracks.

What’s the permanent fix—do I need exterior excavation?

Usually no. We install an interior Fast Track system with a sealed sump and optional battery backup to relieve pressure and move water out safely.

How long does installation take and how should I prepare?

Many jobs finish in 1–2 days. Please move stored items 2–3 feet from the walls; we handle protection and cleanup.

How much does repair cost?

Depends on drainage footage, sump configuration, and any wall/crack repair. We provide a free on-site inspection and written, no-pressure quote.
