Sealing Pipe Penetrations in Foundation Wall with Chemical Grout Injection

Location: Sam Houston State University – Huntsville, TX

Project Spotlight: Sam Houston State University Football Field House Renovation

Background:
Sam Houston State University embarked on an ambitious renovation project for its football team’s Field House and Locker Room.

Scope of Work:
The renovation involved the addition of masonry walls and the sealing of old Pipe Penetrations. Contractors were instructed to remove the existing pipe penetrations, seal them with a grout patch, and subsequently drill a ½” hole through the patch. An injection was then carried out behind the grout patch, ensuring a watertight seal, as outlined by the project engineer.

Expertise in Action:
The project contractor enlisted SealBoss to provide hands-on technical guidance for the specified injection process.

Additional Training:
Beyond the specified injection process, the contractor was also trained in alternative repair techniques. This included using SwellCaulk and Oakum to effectively seal off the pipe penetrations.

This collaborative approach and training ensured the project’s success while also expanding the contractor’s repertoire of repair methods.

Sealing Pipe Penetrations in Foundation Wall – Specified Repair Procedure

After ensuring the grout patch was fully set, the contractor drilled a ½” hole directly through its center. Debris from the hole was carefully vacuumed out, and the hole was subsequently flushed using a specially modified water bottle, ensuring a clean, pressured stream. Once thoroughly cleaned, the ½” SealBoss Evolution 13-100AL injection packer was fitted in place.

Utilizing the SealBoss P2002 pump, the SealBoss 1510 Water Stop Foam System was pressure-injected into the void behind the grout patch. This process guaranteed an air and watertight seal, preventing any water seepage through the patch.
