How to Fix leaky and wet
basements?
The technicians at TerraFirma understand that water is a basement’s nemesis. It’s easy for moisture to slip through the cracks, causing mold and mildew growth alongside expensive foundational damage. If leaking water is a problem in your home, we have plenty of basement waterproofing solutions to fix and prevent this reoccurring complication.
The flood drain channels water away from the foundation and directs it to a designated drainage system. A sump pump activates when water levels rise to immediately remove excess water and prevent flooding. Lastly, the vapor barrier prevents mold growth and water damage by blocking moisture in the space.
Based on the condition of your basement, we can find the best basement waterproofing solution for you! Homeowners from Eugene to Keizer, and Vancouver to Tacoma are breathing easier thanks to our systems. Contact TerraFirma today for services in Oregon and Washington.
Drain System
If there is water leaking into your basement, a perimeter drain could be the right option for you. At TerraFirma, we offer a variety of interior drainage systems to help keep your basement dry and clean.
Below Floor Drain
Our most popular drainage system, the ideal solution for most basement waterproofing applications. This interior drain is designed to be installed below the floor slab, resting on top of the foundation footing.
Advantages
- Installed with minimal invasion of the slab, and all concrete is restored after installation.
- Includes a wall flange with a 3/8″ opening to collect water from walls.
- Able to waterproof concrete block foundation walls.
- Water is collected without the risk of clogs that would halt your system.
Iron Ochre Drain Tile System
Specifically designed for basements affected by iron ochre and iron bacteria. Its wide, accessible drainage channel helps manage the thick, rust-colored buildup that can clog conventional basement drainage systems.
Advantages
- Wide drainage channel designed to manage iron ochre buildup.
- Large, clog-resistant drain openings maintain dependable water flow.
- Removable lid provides convenient access for routine cleaning, flushing, and maintenance.
- Wall flange collects water entering through or running down basement walls.
Baseboard Drain Pipe
If your house has a monolithic foundation, or a foundation that comes with the floor and footing as one piece, jackhammering to install a drain system can be very difficult. In those cases, we use our basebord floor drain system to avoid any problems. This system installs over the top of the floor, eliminating the need for excessive excavation.
Providing the same protection and drainage for water seeping through foundation walls while also providing the clean, finished appearance of a baseboard. The drain is secured to the floor with only a slight opening at the top, allowing water to flow in and drain to your sump pump.
Thin Floor Drain System
Sometimes the concrete floor in a basement is too thin for a drain to be installed on top of the footer. We usually address this challenge with our Thin Floor System. This system is designed to sit in front of the footing in a bed of drainage stone.
Advantages
- Quick installation and seamless finish. After installation, the concrete floor is restored over the drain.
- Includes a wall flange with a 3/8″ opening to collect water from walls.
- This system avoids the “mud zone” to help prevent clogging issues.
Drain Inserts
Drain interts can be installed in an existing trench drain to allow water down without allowing air to come up. The system comes with balls that fit over the drainage holes, creating an airtight seal when there is no water.
Advantages
- Designed to block unwanted ground air and gases from entering the basement and home.
- Easy installation.
Crawl Space Vapor Barrier
Our heavy duty vapor barrier is a 100% waterproof, 120-mil-thick plastic liner that is ideal for unfinished crawl spaces, helping prevent leaks and mold growth. This crawl space liner creates a clean, dry, sanitary, and usable area. With correct installation, it can help insulate your crawl space and reduce energy costs.
Advantages
- Greatly reduces musty smells with an EVOH layer that seals out odors.
- Reduces allergens such as mold and dust mites, improving indoor air quality throughout the home.
- Seals out soil gases while eliminating excessive, destructive moisture that could lead to wood rot.

Sump Pumps
When water gets into your basement, the sump pump is what protects you from a flood or any leaking that could cause expensive property damage. We offer powerful, quiet and reliable pumps and only professional grade, cast iron equipment.
Multi-pump Sump System
The Multi-pump Sump System provides three levels of protection for your basement and your peace of mind. For normal functioning, the Multi-pump Sump System has a powerful, Zoeller® ⅓ horsepower sump pump set at the lowest level. For heavy volumes of water or in case of primary pump failure, a second, more powerful Zoeller® ½ hp pump set a bit higher in the liner will take over. In case of a power outage, our Battery Backup Sump Pump, set at the highest level, will pump 11,500 gallons or more on a fully charged battery.
Advantages
- ⅓ hp primary pump can discharge 2,220 gallons of water per hour at an 8-foot head.
- ½ hp secondary pump can discharge as much as 3,900 additional gallons of water per hour at an 8-foot head.
- In the case of a tripped circuit, power outage, or sump failure, your Battery Backup Sump Pump System will kick in.
- Can support a second battery to achieve extended running time.
Battery Backup Sump Pump System
Battery Backup Sump Pump System ensures continued protection in the event of power loss. The battery backup will automatically kick in and begin removing water from your basement, preventing a flood. The Battery Backup Sump Pump system can pump out in excess of 11,500 gallons of water on a fully charged battery.
Advantages
- Comes with an alarm in case of power failure, sounding when the backup pump is running and silencing when power is restored.
- The alarm also protects you in case the main system is accidentally unplugged.
Basement Sump Pump Premier System
If you have had occasional water issues but not severe leaks or flooding, the Basement Sump Pump System is an effective and more economical solution option for your home.
Advantages
- ⅓ hp primary pump can discharge 2,220 gallons of water per hour at an 8-foot head.
- Optional Battery Backup Sump Pump, which can pump out 11,500 gallons or more on a single charge.
