Basement Remodeling in Culver, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home.

Job Stories From Culver, OR
Dirty, Damp Crawlspace Transformation - Culver City

A homeowner called John's Waterproofing with concerns that mold in the crawlspace was affecting his family's health. We sent design specialist out to do an inspection. We did find signs of water and the resultant mold in the crawlspace so we recommended a CleanSpace encapsulation. 


The crew came out and removed the old, dirty barrier and fiberglass insulation and installed a perimeter perf pipe drainage system and graded it to the new TripleSafe sump and a discharge line was connected to the downspout drainage. TerraBlock, for both protection and insulation, was laid on the ground.  Next the 20 mil, nylon-reinforced  CleanSpace barrier was laid and fastened to the foundation walls just below the rim joist, and all seams were sealed with special, heavy-duty 4" CleanSpace tape, and each post was isolated to ensure that no water/moisture would get to the wood of the home. Lastly, on the exterior, all vents were sealed with specially designed vent covers and on the interior, a 2.5" layer of Spray Foam designed for encapsulation, was sprayed on the foundation walls and rim joist, and a SaniDry Sedona dehumidifier was installed. Now these homeowners enjoy a healthy home free of air contaminants.

Dual Crawlspace and Basement has Water - Culver, OR

This home had a small section of finished basement space which then connected to a crawlspace for the remaining foundation. The crawlspace had always had some water issues, but it seemed to stay in that space until the homeowners noticed their carpeting was damp and soggy. When they lifted up the carpeting near the crawlspace they found standing water, and part of their wall was damaged due to this. 

To solve the issue we started with the crawlspace, where we installed a SmartDrain and encased the space with our 20 Mil thick Cleanspace vapor barrier. We isolated the posts to protect them from water damage and anchored to walls. We then installed our SilverGlo insulation on the foundation walls to help regulate the energy consumption of the home. The crawlspace also got new vent covers. In the basement, we removed the carpeting and the damaged portions of the wall. We installed our WaterGuard drainage system around the interior perimeter of the room and sent all collected groundwater out and away from the home via a discharge line. We then installed our Everlast finished wall restoration system and our ThermalDry gray carpet squares to give this space a clean, dry and finished look. 

Crawlspace Water Build Up - Culver, OR

This house had experienced a large amount of water intake throughout the years. The homeowners had grown used to this and figured it was just how things went. After a musty and damp smell began to permeate their home, they decided there must be a better way. To eradicate the problem, they called John's Waterproofing. They had a large crawlspace with the dirt floor varying from two to four feet. The varying floor levels led to many sections with pooling water and places where debris would accumulate. 

The first issue to address in this project was to address the inconsistent floor levels. Our crew cleared out the debris and began to level the floor, grading it to a low point. Here we put in a SmartSump Sump Pump, specially created for crawlspaces. Then TerraBlock was laid and posts were isolated. We then isolated each post and covered the crawlspace with Cleanspace, a woven, and tear-resistant 20 Mil Vapor Barrier. This is fastened along all the concrete walls. Since the space also had high humidity, we added in a SaniDry Sedona dehumidifier to ensure no water vapor could creep into the home. 

The homeowners quickly noticed a change in the air quality and were amazed at how much fresher their home smelled. No more musty smells, and no more water intrusion. 

CleanSpace Encapsulation in Culver, Oregon

This homeowner called because they were concerned about the amount of water in their yard and the pooling around their foundation vents. They were sure that it was getting into the crawlspace. When our inspector Jacob went into the crawlspace, he confirmed the homeowner's suspicions. The water coming into through the vent was not the real problem though. This crawlspace has groundwater coming in from a corner of the foundation. The crawlspace had two inches of water across the vapor barrier and some areas where deeper pools had been created. Due to the water, the fiberglass insulation was falling and full of water. Jacob suggested our CleanSpace Encapsulation System. He also added an exterior French Drain in order to help prevent the groundwater from continuing to come into the space. The customer opted to have TerraBlock flooring installed as well as spray foam insulation on the walls. This insulated the space and will provide an average of 30% savings on their heating and cooling bills.
