Albert N. Parlin School

Albert N. Parlin School - Everett, MA

THE CHALLENGE
Routine construction had exposed failed, separated masonry in the interior brick walls on two levels of the Albert N. Parlin School in Everett, MA.

THE SOLUTION
The Alpha Weatherproofing Team successfully performed carbon fiber strengthening of the structure’s non-reinforced masonry walls

Photo 1: Failed, separated masonry in the interior brick walls on two levels of the Parlin School.

Photo 2: All voids and cracks were filled with SikaGrout212 by forming and pouring, or the dry pack method. Smaller cracks were injected with Sika epoxy of various viscosities.

Photo 3: Dustless grinding was performed to level the surface and remove small projections on the surface.

Photo 4: Sikadur330 epoxy was applied to the surface and a layer of SikawrapHex 430G was then applied and dry-rolled to bring the epoxy through the carbon fiber mesh.

Photo 5: A second layer of Sikadur330 epoxy was applied and the SikawrapHex 430G was applied in the opposite direction.

Photo 6: A top-coat of epoxy was then applied to seal the surface and complete the project.
