## How Our Waterproofing System Works

Our system controls water at every point — outside the wall, under the slab, at foundation cracks, and through a properly discharged sump pump.

### Step 1: Stop Water at the Wall
Exterior membrane and dimple board keep water out of the foundation wall and direct it down into the drainage system. Components include top termination above grade, waterproofing membrane, dimple drainage board, and drainage stone.

### Step 2: Collect Water at the Footing
Water flows down the wall and is collected by perforated weeping tile set at footing level, surrounded by clean gravel and filter fabric. Components include the foundation wall connection, filter fabric, perforated weeping tile at footing level, and gravel bed.

### Step 3: Direct Water to the Sump
A perimeter drain system installed below the slab channels water to the sump basin, keeping the basement dry. Components include interior perimeter drain below the slab and a sealed sump basin.

### Step 4: Pump It Away Safely
The sump pump removes water automatically. A check valve prevents backflow and the discharge line carries water safely away from the home. Components include the sump pump, check valve, sump discharge line, and water directed away from the foundation.

## Warning Signs Your Basement Has a Water Problem

1. **Water at the Floor-Wall Joint**: Often linked to hydrostatic pressure or failed drainage at the footing.
2. **Vertical Foundation Cracks**: Most vertical cracks can be injected, but widening or horizontal cracks may need further review.
3. **Efflorescence / White Staining**: Mineral deposits can mean moisture is moving through concrete or block.
4. **Musty Smell or Damp Air**: Persistent humidity may point to hidden seepage and can contribute to mold growth.
5. **Peeling Paint or Damp Drywall**: Finished basements often hide water damage until it spreads and becomes costly to repair.
6. **Sump Pump Running Often**: Frequent cycling can signal high groundwater, a drainage issue, or a failing check valve.
7. **Rust Stains on Floor or Walls**: A common sign of chronic slab or wall moisture in older basements.
8. **Water Backing Up from the Floor Drain**: Can indicate drainage issues, municipal surges, or the need for a backwater valve.
