Job Stories From Vancouver, WA
Crawl Space with Dry Rot Vancouver, WA

    When a crawl space or basement isn't properly waterproofed or protected from moisture, issues are going to arise, especially in the northwest. Vancouver, WA home owner Al and Patricia H. have a large crawl space with a large amount of water, giving them a large problem. The issues have been around long enough to create a significant amount of dry rot in the load beams. Knowing they had an issues that wasn't going to fix itself, they called TerraFirma after seeing numerous positive reviews on Yelp.

    Design Specialist Josh Anderson suggested that after the mold is removed using Mold X spray, that the crawl space be encapsulated to eliminate the chance of further dry rot or mold development. By controlling all groundwater seepage, uncoupling the earth from the house, blocking off the vents and installing a dehumidifier, Al and Patricia are able to control moisture, water, and temperature levels under their home.

    By performing this service to their home, not only are Al and Patricia restoring market value but creating a more comfortable, healthier more energy efficient living situation.

Crawl Space Insulation Vancouver, WA

    The benefits to properly conditioning your crawl space are endless, and like all home improvements, the earlier you have them performed, the sooner you can enjoy those benefits. Whether the reasons be for energy conservation, high performance home systems, money savings, health, home comfortability, there is no wrong answer so take your pick. For Vancouver, WA home owners Jim and Gail, their crawl space was in great condition already. The waterproofing system was working great, and there was virtually no moisture in the area. Their goal was to insulate their crawl space and provide more comfort in their home.

    SilverGlo wall insolation is installed on the interior siding of the foundation walls in the crawl space. This solution is designed to reflect warm air back into the crawl space. By retaining warmth, not only can you, your family and guests enjoy the comfort, but also reduced energy consumption and expenses through not having to heath the home as much.

    Like before, there are countless benefits to crawl space repair and conditioning. Just take your pick.

Sinking Slab Vancouver, WA

    Cement slabs will settle for two main reasons. The first is the weight of the supported structure is too much for the soils or two, water will wash out soils from underneath and create voids that the slabs will settlement into. Vancouver, WA home owner Scott C. was experiencing uneven and cracked slabs throughout his property. After searching online for a company that could help him level out his property, he found TerraFirma and the concrete leveling solution.

   Our concrete leveling solution is a lightweight polyurethane that is injected under the sinking slab into the void. Once injected, the polyurethane foam expands and fills the void completely. Because of it's high capacity and light weight, the slabs are lifted and no extra weight is added to the soils below to encourage more settlement. 

    This is a perfect residential and commercial solution with quick and easy application. Scott is happy to have a level yard again that he can be confident will stay like this for many years to come. 

Properly Waterproof the First Time

Many times our team inspects homes that are continuing to have water issues in their basement because they hired some other contractor who only finished the job half way. That's when they call us. Deryl George inspected a home in Battle Ground, WA and found this exact scenario. 

To some extent the waterproofing system was working; however, there was no proper removal of the water and it was draining right back into and under the home. The solution was to up the fire power of their sump pump system and install proper discharge line. Deryl designed a two sump pump system at opposite ends of the basement and a discharge line that properly removed water out of the basement and away from the foundation.

Michael G. is now happy to have a waterproof, livable basement, increasing the square footage and value of his home.

Smart Jacks and Cleanspace Beautify Home in Vancouver, WA

The Northwest is a beautiful place to live. The landscape is so diverse and green because of the year round heavy rain fall. Although these conditions are why our terrain is so beautiful, it can be harmful to your home and specifically the foundation. A Vancouver, Washington home has suffered from years of moisture problems causing the humidity and mold levels to rise, and the floors to sag due to rotting supports. To restore the value of the home, the foundation will need to be stabilized and the crawl space environment conditioned. 

To achieve the first goal, Smart Jack posts were installed and secured to the support beams under the house. These easy to install and adjust steel supports will not only stabilize the foundation from continuing to sag, but will also raise the floor up to eliminate the "bounce" in your step. To achieve the second goal of conditioning the crawl space environment a combination of products were installed; Cleanspace liner isolates the air from the Earth, SilverGlo wall insulation regulates air temperature reflecting warm air back into the home, insulating and heating at the same time, and a sump pump and dehumidifier to regulate the moisture and humidity levels.

the Rauch's are very happy with their new crawl space, all the while improving the comfortability for their family and increasing energy efficiency. A win-win all the way around.

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.
