Key Projects Using Caulking & Sealant Replacement

M.A.T.C.H. School Restoration - Phase II

Owner:       M.A.T.C.H. Public Charter School Foundation

Location:   1001 Massachusetts Avenue, Boston MA

Engineer/Architect:  JCH Consulting

CSI was awarded the contract to reinforce and waterproof the compromised building envelope of the M.A.T.C.H. Public Charter School.

Phase II entailed the removal of the exterior brick and limestone veneer of the Commonwealth Avenue façade, the installation of a liquid membrane waterproofing system, new angle irons for all windows, replacement of the window brackets and the subsequent re-building of the façade to match the original.

The existing parapet wall was rebuilt including a new roof flashing system and a new waterproof membrane to tie into the existing roof. On completion of the re-build, waterproofing sealant was installed at all joints and the exposed concrete foundation wall was repaired and coated to match the existing building.

At the rear of the building, CSI removed multiple deteriorated masonry panels, installed a structural waterproofing skim coat on the brick substrate, and reinstalled the masonry to match the existing.

Multiple spalled concrete areas were repaired and a new breathable masonry coating was applied to all concrete beams and spandrels. A waterproofing sealant was installed at the perimeters of all the masonry panels.
