If holes/damages to the brick <br />are discovered below grade, infill holes with repair mortar prior to installation of parge coat and <br />waterproofing system. <br />D. Mix parging material in strict accordance with the requirements of the material manufacturer. Do <br />not exceed the recommended water content/ratio during mixing. Trowel apply the parging <br />material to the masonry surface in accordance with manufacturers recommendations and to obtain <br />a smooth, even surface acceptable for application of the specified sheet waterproofing membrane <br />without fins, projections, or voids. Do not exceed maximum lift thickness designated by the <br />manufacturer. <br />E. All parge coat to fully cure prior to application of primer and installation of the sheet <br />waterproofing system. Provide protection during curing to prevent shrinkage cracking of the <br />parge coat. <br /> <br />3.2 SHEET WATERPROOFING INSTALLATION <br /> <br />A. Apply surface primer using roller type and the coverage rate recommended by the manufacturer. <br />Allow primer to dry until it is tack-free unless otherwise required by the manufacturer. Re-prime <br />areas that become contaminated with dust or other debris. Do not apply primer directly to water- <br />proofing sheet membrane. <br /> <br />B. Apply detailing tapes, liquid membrane, mastics, and sealants at transitions between vertical wall <br />and top of footing, inside and outside corners, footing steps, penetrations through the wall, and <br />at transitions to work not in scope in accordance with the design details and manufacturer’s rec- <br />ommendations. <br /> <br />C. Install self-adhered waterproofing membrane on vertical surfaces. Overlap all seams a minimum <br />of 2.5”. Roll all membrane seams with a hand roller. Sheets should be oriented with vertical <br />joints. If more than one course of membrane is required, the upper layer must overlap the lower <br />by a minimum of 2.5”. Extend the waterproofing onto the top of the footing enough to cover the <br />transition strip by a minimum of 2”. Apply mastic to the joints within 12” of a transition/change <br />in direction. Install target patches and additional sealant/mastic at penetrations through the mem- <br />brane. <br /> <br />D. Terminate the top of the membrane approximately 1”-2” below the planned new grade level, to <br />ensure that the waterproofing and top edge of the protection board will be covered and will not <br />be exposed to UV or general landscaping activities. Secure the top of the membrane with a ter- <br />mination bar fastened at a maximum of 8” o.c. Apply detailing sealant/mastic along the top of <br />the termination bar and covering fasteners as required by the manufacturer before covering. <br /> <br />E. Allow for the installed membrane to be inspected prior to covering. Make repairs to tears, cuts, <br />and inadequately lapped seams. Fishmouths must be slit and repaired with a patch extending a <br />minimum of 6” in all directions. Edges of the patch must be sealed with the manufacturer’s liquid <br />membrane. <br /> <br />DocuSign Envelope ID: 7D9ACD4F-8F6C-42B6-9ADB-C60032DB6D03
