How the WallSeal™ Vapor Barrier Works 

Once a BQ Basements & Concrete specialist assesses your basement and confirms the need for the WallSeal™ Vapor Barrier, it will be integrated with our array of basement waterproofing solutions. 

This is our processes: 

  • Thoroughly clean and prime the walls. 
  • Securely apply sheets of WallSeal™ onto the prepared walls. 
  • Establish the interior drainage system and install any remaining components. 
  • Position a sump pump in the lowest section of the basement. 
  • Connect the basement interior drainage system to the sump pump. 
  • Install a basement dehumidifier. 

Here’s an overview of how the system operates: 

  • When water infiltrates through basement walls, it naturally moves behind WallSeal™. 
  • WallSeal™ guides this seeping water toward the interior drainage system. 
  • The water within the drains is subsequently directed to the sump pump. 
  • The sump pump removes the collected water from its basin. 
  • The basement dehumidifier addresses any remaining moisture. 

BQ Basements & Concrete’s expertly installed water management components provide crucial basement protection.
