John's Waterproofing Before & After Photos

This crawl space would regularly flood, and the fiberglass and vapor barrier needed to be replaced to keep up with this. To end the flooring the homeowners were ready to get a drainage system and sump pump to ensure the flooding would no longer occur. This will help prolong the life of the 6 Mil vapor barrier and allow the homeowners to not have to replace it as often. 

These homeowner had us install a partial system for them a few years ago, a drainage channel, sump pump and 6 mil black plastic vapor barrier. While that was helpful, it was only a temporary solution. During their annual maintenance service that we provide, the technician noticed a high level of humidity. Once our service technician spoke to the homeowners about the benefits of a full encapsulation system, they wanted to move forward with the project. To begin, we remove all the debris in the space, including the old vapor barrier. Because of the humid environment, and wood being an organic material, this crawl space had some mold spots, so we treated this with our Mold X-2. This is our highly effective cleaner for contaminated surfaces. Mold stains are removed in 20 seconds. Since we already installed a drainage system with the sump pump, we moved along to install our TerraBlock system. This will create an insulated barrier between the home and the earth. On top of the TerraBlock, we install our CleanSpace vapor barrier. This is our 20 mil vapor barrier, that is puncture resistant and manufactured with an antimicrobial additive called UltraFresh molded into the material. It goes all along the foundation walls, up to the rim joists and is sealed at the footing of the wooden posts. With the bright white finish of the CleanSpace, the homeowners will be able to see there is no dirt, mold and debris in the space over the years. We also cover all of the vents in the space make sure no outside air enters. To control the humid environment, we installed our SaniDry Sedona. This effective dehumidifier will eliminate damp musty odors while drying and filtering the air, keeping the space at a healthy relative humidity. Lastly, we install our foam insulation. This is sprayed all along the foundation walls, up to the rim joists and will fill every crack and void increasing effectiveness and performance. This process ensures an air tight seal, offering years of protection for this home. 

The owners of this industrial building were concerned when they found standing water in the crawlspace. They called on John's for help, and we arrived quickly to assess the situation. Because the crawlspace was so downwardly sloped, water intrusion posed risk. The longer the water intrusion was allowed, the higher the likelihood that severe damage could befall the building. This is because over time excessive moisture would cause erosion of the soil supporting the foundation walls. This erosion would eventually cause the foundation to slide downhill, causing catastrophic damage to the structure. We thoughtfully explained the reality of this situation to the business owners, and they understood the long term implications to the structure if they opted to not make any repairs. They eagerly decided to do the right thing, and scheduled with our waterproofing and structural crews to begin repairs.

The first step of this job, is to dig out a small portion of the dirt at the bottom of the downward slope of the ground. Then, we backfilled the area with compacted gravel. Next, we built concrete forms, and laid down rebar so that we could pour concrete over the gravel. Doing this would help prevent the ground from sliding further downhill. After pouring and finishing the concrete, we began waterproofing the crawlspace. First, we laid down our 3" Perforated Pipe around the entire interior perimeter of the space. The piping will collect all water intrusion, and will direct it to a SuperSump Pump, with an UltraSump backup. The pumps will pump all of the collected water a safe distance away from the building via the discharge line. On top of the piping, we laid down TerraBlock foam padding, which will help insulate the space, and will protect the CleanSpace Vapor Barrier on top of it from the rocky ground beneath. Our CleanSpace Vapor Barrier is 20 Mil thick, and is interlaced with carbon fibers to prevent rodents from chewing on it. It is also very durable, and can be walked on, or used as storage space. It is guaranteed for 25 years to not rip or tear. In addition to laying the CleanSpace Vapor Barrier on the ground, we also attached it directly onto the foundation walls, to prevent water seepage from entering the space. Directly on top of the CleanSpace, we installed our SaniDry Dehumidifier, which will remain permanently in place to ensure that the relative humidity never enters the threshold where mold can grow. Dehumidifiers play a vital role in the absolute protection against moisture damage in crawlspaces. In order to supply power to the Sump Pumps, as well as the Dehumidifier, our Electrical Division came out and installed a dedicated electrical outlet for the machines. This industrial crawlspace has now been professionally waterproofed, and because of this, the entire structure will remain permanently supported by ground that is not overly wet or unstable. These business owners should be proud that they did the right thing, by hiring the leading experts in crawlspace waterproofing and structural stability!

The standing water and moisture in this home were a constant issue. Now with the CleanSpace system and dehumidifier the house is comfortable, moisture free and more energy efficient. 

This Gresham home was in need of a cleanspace and smart jacks after the moisture under the home got to the wooden posts and they rotted out causing the floor to sag.
