John's Waterproofing Before & After Photos

The owner of this commercial building was getting a lot of complaints from the tenants about musty smells and humidity issues, so they called John's Waterproofing to get a free estimate and inspection. The owner met with our system design specialist after the inspection and went over options. They chose a full encapsulation for this massive crawl space. To begin this project we start by removing all the debris in the space. Next we dig a trench around the interior perimeter of the entire crawl space and lay down a perforated pipe into a silt sock to secure a safe passage for water to drain to the Sump pumps. We installed our SuperSump Plus with our UltraSump battery backup at the lowest point. Then, we installed a discharge line outside and away from the foundation. One of the retaining walls was crumbing, so we poured a new concrete wall to ensure the space remains on solid soil. We then install our TerraBlock system. This goes directly on the dirt floor of the crawl space creating an insulated barrier between the building and the earth. On top of the TerraBlock, we install our CleanSpace system. This goes all along the foundation wall and covers the entire crawl space floor. Lastly, to help with the humidity and musty smells, we install 2 of our SaniDry Sedona dehumidifiers. It will eliminate damp odors by drying and filtering the air, all while promoting healthy air throughout the entire building. 

This Lake Oswego crawl space was coated in mold and drenched with standing water. It was a hazardous zone, sending unhealthy air up into the home. The homeowners reached out to John's Waterproofing for an inspection and to help them decide how to protect their home and family without putting a dent in their wallet. After one of our Design Specialists took a look down under, they discussed with the family and made a plan that implemented to address the major issues at hand. Shortly after, the project went underway.

Our Waterproofing Experts removed all debris from the crawl space: the raggedy, moldy vapor barrier, and standing water. Then our crew performed Soda Blasting, sending high-pressure baking soda, to neutralize and eliminate mold growth. Once the mold was taken care of and the dirt floor was unveiled, a trench was dug along the interior perimeter of the space, and a Perf Pipe was inserted. This drainage system sends collected groundwater to the sump pump and is wrapped in a silt sock to ensure no debris can enter and clog the pipe. This led to the installation of a SuperSump Plus, a sump pump system that pumps water out from the crawl space with a discharge line attachment. The water intrusion had finally been taken care of, so lastly, a fresh 6-mil vapor barrier was attached to the floor to trap moisture from rising through the dirt. The homeowners felt relief knowing the mold and standing water had been addressed, giving their crawl space a cleaner and safer environment beneath the home, and protecting the family above.

This homeowner had reached out to John's Waterproofing back in 2015 about getting their crawl space inspected. They noticed that during the rainy seasons water would seep inside the space and puddle. Because of this, the water would bring in dirt and debris from the outside and leave it behind on the vapor barrier as the water evaporated. We explained that a full encapsulation would prevent these water issues from continuing and they decided to wait and see if the issue resolved itself. Then, in 2025 the same homeowner reached back out saying that the water issues they were experiencing had only worsened and agreed to encapsulate the space. A full encapsulation is the process of sealing the crawl space off and controlling the environment to help prevent water intrusion, mold growth, and wood rot. It involves installing a drainage system with a TripleSafe sump pump, TerraBlock insulation foam, and a CleanSpace vapor barrier. Now, this beautiful crawl space is capable of keeping water out and the home healthy. 

This homeowner called us first to discuss waterproofing her crawlspace, and then asked if we could also repair her concrete driveway. We let her know that we are experts in both of those fields! After completing a thorough inspection, and presenting her with a no-obligation quote, the homeowner decided to move forward with waterproofing her crawlspace, and with the removal and replacement of her driveway. After finishing waterproofing her crawlspace, we began working on the driveway. It was damaged past the point of being repaired, so we chipped out and removed the old concrete. Next, we laid down our forms, and then poured the new concrete. After it solidified, we gave it a beautiful broom finish! This homeowner was very excited to have her crawlspace waterproofed, and with a spectacular new driveway to boot!

This homeowner was struggling with strong odors coming from their crawl space so they wanted to find a solution that would permanently solve this issue. They reached out to John's Waterproofing to get the job done. After sending our system design specialist to perform a free estimate and inspection, he met with the homeowner to discuss options for this crawl space. They decided an encapsulation would be the best way to go. Not only does it improve air quality in the home, it also offers protection from mold and mildew and increases the home's value. It also reduces energy costs by creating a barrier against moisture and air leaks, which will help maintain a consistent temperature in the home. To begin this project we start by removing all the debris in the space.  Since this space did not have much water, we installed our SmartDrain system. This will alert the homeowner of a possible plumbing leak with an audible alarm and will drain the water into a drywell underneath the CleanSpace until the homeowner can address the leak. Then, we install our TerraBlock directly on the dirt floor of the crawl space and this will create an insulated barrier between the home and the earth. On top of the TerraBlock, we install our CleanSpace system all along the foundation walls, up to the rim joists and seal all the vents in the space to ensure no outside air enters. We make sure to seal the CleanSpace with our waterproof tape against the footing of the wooden posts. We install our SaniDry Sedona to control the environment and this will eliminate the damp musty odors the homeowner was concerned about by drying and filtering the air. It will also keep the space at a healthy relative humidity. The final step is to install our foam insulation. We spray the foam along the walls of the foundation, up to the rim joists providing a well insulated and airtight crawl space for this homeowner.
