Basement Waterproofing Photo Album: Waterproof Before Finishing the Basement - Seattle, WA

After years of water seeping into their finished basement, this homeowner decided it was time for some home improvements, including making the basement a dry and healthy space. They decided to call John's Waterproofing to get their basement fully waterproofed so that it could stay dry and healthy while they made some home upgrades. Our basement waterproofing system begins by a crew installing a proper drainage system. This is important to have control over the flow of water and give it a safe exit place. This is done by jackhammering a trench along the interior perimeter for a WaterGuard drainage pipe to be laid into. This pipe sits at the footing of the basement and is lined with gravel so water can easily filter through. The cuts in the pipe help to collect water coming in from the walls or rising from the ground. After the WaterGuard is installed and covered with concrete, then it gets connected to a TripleSafe sump pump. The sump pump is what takes all the collected water from the pipe and can safely push it out and away from the homes foundation. It is a three-pump system that can control hundreds of gallons of water and even has a back up battery-operated pump in the case of a power outage. These two work together to keep water out of the basement and prevent future flooding. In order to protect the walls before the basement gets finished, then we install ThermalDry. This is a heat and vapor barrier that goes along the basement walls. It is anchored to the walls and sealed with thick waterproof tape. It's goal is to be a guide for moisture on the walls to be sent down below to the drainage system and be pushed out. We can ensure a secure passage of water from the walls to the WaterGuard because the ThermalDry gets shingled behind the system. Now that the basement is fully waterproof, the homeowner can finish the basement without worrying about the threat of future water intrusion.
