DocuSign Envelope ID:070B6BC7-CDE2-4AO8-BE62-07FA6BFDO53B <br /> 11/20/2020 <br /> hand tools based on access to the work area and the excavation shall be properly sized to allow <br /> for safe and proper access to the substrate to be waterproofed. <br /> A. Inspect and clean the surface of the exposed brick masonry foundation wall and top of the footing. <br /> Use of wire brushes, vacuuming/scraping, and other cleaning methods shall be used as needed to <br /> remove loose materials,dirt and debris from the masonry surface to provide the substrate condition <br /> required for application of the cementitious parge coat. <br /> B. 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 material <br /> to the masonry surface in accordance with manufacturers recommendations and to obtain a smooth, <br /> even surface acceptable for application of the specified sheet waterproofing membrane without <br /> fins,projections, or voids. Do not exceed maximum lift thickness designated by the manufacturer. <br /> C. All parge coat to fully cure prior to application of primer and installation of the sheet waterproofing <br /> system. Provide protection during curing to prevent shrinkage cracking of the parge coat. <br /> 3.2 SHEET WATERPROOFING INSTALLATION <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 /> 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 at <br /> transitions to work not in scope in accordance with the design details and manufacturer's recom- <br /> mendations. <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 joints. <br /> If more than one course of membrane is required,the upper layer must overlap the lower by a min- <br /> imum of 2.5". Extend the waterproofing onto the top of the footing enough to cover the transition <br /> strip by a minimum of 2".Apply mastic to the joints within 12"of a transition/change in direction. <br /> Install target patches and additional sealant/mastic at penetrations through the membrane. <br /> D. Terminate the top of the membrane approximately 2"above the planned new grade level,or slightly <br /> higher to make sure that brick is covered and will no longer be in direct contact with the soil in the <br /> area to be waterproofed. Secure the top of the membrane with a termination bar fastened at a max- <br /> imum of 8" o.c. Apply detailing sealant/mastic along the top of the termination bar and covering <br /> fasteners as required by the manufacturer. <br /> E. Allow for the installed membrane to be inspected prior to covering. Make repairs to tears,cuts, and <br /> inadequately lapped seams. Fishmouths must be slit and repaired with a patch extending a minimum <br /> of 6"in all directions. Edges of the patch must be sealed with the manufacturer's liquid membrane. <br /> F. Protect the waterproofing membrane to prevent damage during backfill. <br /> 07 1300 BELOW GRADE WATERPROOFING Page 5 of 7 <br />
