Job Stories From Lake Stevens, WA

Moisture Coming Through the Basement Floor - Lake Stevens, WA

This basement floor would have the moisture come up it when heavy rains occurred. The owner had another company install French drains to the exterior of the home, yet the moisture was still coming up through the floor. Not wanting to dig around the outside of their home again, this owner contacted John's Waterproofing to see how we could address this issue. We did a full inspection and than sat with the owners to go over a game plan. To begin we installed our WaterGuard system on the inside perimeter of the basement. We than dug leech lines. This is a trench that goes through the basement floor to the spots where the water is coming up. This allows us to collect the groundwater where it is actually appearing. The water than travels through the drain channels we install here and they guide the water to the WaterGuard and than to a TripleSafe sump pump. From here the water is pumped away from the homes foundation. This entire drain system is than concreted over, providing a discreet look to the waterproofing system as a whole. We than installed our CleanSpace wall system, which just ensures if moisture comes through the foundation walls, it can be guided to the WaterGuard system safely as well. To control the spaces relative humidity we finished this project by installing a SaniDry dehumidifier. The owners happily called us after the first big rain to inform us they don't have water coming up through their floor and they are happy to see the system doing it's job.

The Damage a Wet Crawl Space Causes to Your Home - Lake Stevens, WA

This homeowner wanted to get their crawl space inspected after not going down there in a long time. Upon inspection, it was discovered that there was significant water damage occurring in the crawl space, causing damage the wooden posts supporting the home. They asked what could be done to fix this issue and we suggested a full encapsulation along with installing SmartJacks.

To begin the full encapsulation process, we first need to install a drainage system. Drainage is important so that there is a safe passageway for water to flow through and be pushed away from the homes foundation. It helps to protect against standing water or moisture damage if that water evaporates and gets into the air. We dig a trench along the interior perimeter of the crawl space and lay a perforated pipe. This pipe then connects to a TripleSafe sump pump. The sump pump takes all that water and is able to push it out of the crawl space and away from the homes foundation through a discharge line. After a drainage system is installed, then we can start installing an insulation foam. The thick 3/4 in. insulation foam, TerraBlock, is installed along the base of the crawl space. This is a moisture barrier that separates the earth from the home and closes the crawl space off. Over top of the TerraBlock we install a new CleanSpace vapor barrier. This vapor barrier is stronger than code regulated ones because it is made of 20 mil thick woven fibers and is backed by a 25 year warranty against rips and tears. It is installed along the base, up the foundation walls, and between the footing and wooden posts. Next, we install a SaniDry dehumidifier that controls the environment by pulling any moisture out of the air. Finally, Spray Foam is applied to the foundation walls to insulate and air seal. This is the completed encapsulation process so no more water can have access into the crawl space and it is closed off from the outside air. In order to fix the damage done to the wooden posts, we install SmartJacks. These are adjustable steel piers that stabilizes the home in places where the previous posts have rotted. Now the homeowner can enjoy a dry and healthy crawl space that will support their home.
