Questions and Answers

Why are my basement walls wet?

Water builds up outside of your foundation, creating hydrostatic pressure, and causing your basement walls to crack and leak.

What is hydrostatic pressure?

Hydrostatic pressure is the water pressure that pushes against your home. If not addressed, this pressure, along with soil settling and seasonal changes, may cause cracks in your basement walls and concrete foundation.

What is cove joint seepage?

Cove joint seepage occurs when hydrostatic pressure forces water into your basement through wall cracks, causing water leaks where your walls and floor meet.

Why are my basement walls cracking?

Concrete cracks are a common problem caused by expansion, soil upheaval, and freeze-and-thaw cycles. If left unattended, they invite water inside and can lead to further structural issues in your basement walls or floors. TerraFirma's waterproofing experts have the expertise and knowledge to find the best solution for your basement water problems, regardless of the size or severity of the issue.

What causes efflorescence?

  • Salts: Basement walls are generally made with a variety of brick containing limestone clay or sand. These items are full of natural minerals that contain salt. The salt is dissolved by water in your basement walls.
  • A Water Source: Water can build up outside your foundation, resulting in hydrostatic pressure. This pressure then pushes that moisture into your basement.
  • An Entry Point: The water must be able to enter the basement - whether that be through the floor or the pores in the concrete.

Why does my basement smell musty?

Musty, stale or damp smells coming from your basement can be the result from lack of ventilation, high levels of humidity and can be a sign of mold or organic growth. Schedule a FREE consultation with our team so we can find the best solution for you and your home.

Is a dehumidifier essential for basement waterproofing?

Yes. TerraFirma's powerful, energy-efficient dehumidifiers dry your basement by extracting several gallons of water per day while filtering mold spores and dust.

What are footing drains?

Footing drains are installed just outside the foundation of your home's basement. These are thick pipes with holes designed to let water flow inside. A layer of stones is put on top of the drainpipe to prevent soil backfill from blocking the pipe.

However, with time, backfill can seep through the stones and clog the pipe. The only way to clean the footing drain is by digging up the ground and flushing the pipe, which can be quite expensive. Therefore, it is essential to ensure that the footing drain is functioning correctly to prevent any basement flooding.
