Gonzalez Structural Engineering 661.709.1416 jgonzalez5476@gmail.com J . � ll CoolFnas & waterproofing DESCRIPTION CCW MiraCLAY has a uniform layer of sodium bento- nite clay that is sandwiched between a durable punc- ture resistant nonwoven polypropylene fabric and a high tensile strength woven polypropylene fabric and then needlepunched together with thousands of high strength denier yarns. These fibers are then thermally fused to the polypropylene in a patented InfrabondTM procedure that locks the sodium bentonite into place. TYPICAL USES CCW MiraCLAY is designed for waterproofing below grade structural slabs as well as construction methods incorporating lagging, concrete caisson or shotcrete re- tention walls. CCW MiraCLAY is also very effective in rehab waterproofing and zero clearance property line construction. ADVANTAGES The CCW MiraCLAY waterproofing membrane has the ability to heal itself if ripped or punctured. • 1n a hydrated state the bentonite-clayhas tremen- dous impermeability and excellent resistance to chemicals (i.e., acids, bases and hydrocarbons). • The CCW MiraCLAY has the ability to expand and seal cracks in concrete. INSTALLATION UNDERSLAB APPLICATIONS CCW MiraCLAY is designed for use under reinforced concrete slabs 4" (100 mm) thick or greater on a com- pacted earth/gravel substrate. If installed over a mud slab, CCW MiraCLAY requires a minimum 5" (150 mm) thick reinforced concrete slab. For contaminated site water conditions, as determined by a site water analysis, CCW MiraCLAY EF should be used. When hydrostatic conditions exist, CCW MiraCLAY should be installed under footings and grade beams as shown in CCW MiraCLAY details. SUBSTRATE PREPARATION NOTE: Do not begin construction in work areas where there is standing water or in situations which may cause the CCW MiraCLAY to prematurly hydrate. Before installing CCW MiraCLAY, the substrate must be properly prepared. Substrate may be concrete, earth, sand, pea gravel or crushed stone. Earth and sand sub- strates should be compacted to a minimum 85% Modi- fied Proctor density. Crushed stone should not be larger than 3/4" (18 mm) in size. Substrate should be smooth and uniform without sharp projections or pockets. Com- plete all required elevator pit, sump pit and grade beam and piling work before installing CCW MiraCLAY under main slab area - —INSTALLATION Install CCW MiraCLAY over the properly prepared sub- strate with the non -woven geotextile side up. The CCW MiraCLAY product name is printed on the non -woven geotextile side. Overlap adjoining edges a minimum of 4" (100 mm); stagger sheet ends a minimum of 24" (600 mm); and nail or staple edges together as required to Prevent any displacement during concrete placement. CCW MiraCLAY Granules may also be placed in the seam for additional waterproofing performance. When the slab is poured in sections, CCW MiraCLAY should extend a minimum 12" (300 mm) beyond the slab edge.

At the corner, CCW MiraCLAY should remain in contact with the substrate and inside the surface of the concrete form. When the form is removed, the CCW MiraCLAY outside the form should be positioned and fastened onto the footing or vertical wall. Overlay the CCW MiraCLAY a minimum of 6" (150 mm) with the succeeding vertical waterproofing membrane. At property line retaining walls, such as soldier pile or lagging, continue the underslab CCW MiraCLAY appli- cation up the retaining wall a minimum 12" (300 mm) above the top edge of the slab or footing and secure. Overlap the vertical CCW MiraCLAY waterproofing mem- brane by a minimum of 6" (150 mm) or a minimum of 12" (300 mm) under hydrostatic head conditions. PROPERTY LINE OR LAGGING APPLICATION SUBSTRATE PREPARATION Gaps between the wood lagging greater than 1" (25 mm) must be filled with cementitious grout. In areas with large gaps (1" to 5" / 25mm to 125mm) between lag- ging, install plywood to provide a uniform substrate. Where drainage issues may arise, install CCW MiraDRAIN to provide a uniform substrate as well as to facilitate drainage. INSTALLATION Install CCW MiraCLAY with the non -woven side facing the installer. The CCW MiraCLAY product name is printed on the non -woven geotextile side. Secure the COW MiraCLAY-into-position with fasteners and-V (25 mm) washers. Use the appropriate fasteners for the type of substrate used to receive the CCW MlraCLAY. Install succeeding courses of CCW MiraCLAY by over- lapping the previous course a minimum of 4" (100 mm). Stagger the seams a minimum of 24" (600 mm). Install in shingle fashion so that the upper roll of CCW MiraCLAY is overlaps the lower roll. Fasten membrane once every 2' (60 cm) to 3' (90 cm) on seams or as required to prevent blousing. At grade line, after the wall has been poured, terminate CCW MiraCLAY with a rigid termination bar or fasten 12" (300 mm) on center. Embed the top edge of CCW MiraCLAY and termination bar with a thick bead of CCW MiraCLAY Mastic 2" (50 mm) wide by 1/2" (12 mm) thick. STANDARD FOUNDATION WALLS SUBSTRATE PREPARATION The substrate must be properly prepared to receive the CCW MiraCLAY waterproofing membrane. All honey- combs, form -tie cavities and indentations should be filled With CCW MiraCLAY Mastic or filled with latex Portland Cement. Substrate must be smooth and uniform re- moving any protrusions over 1/2" (12mm) from the sur- face. Footings must be free of soil, rocks or debris to provide a suitable substrate to receive the CCW MiraCLAY waterproofing membrane. INSTALLATION The CCW MiraCLAY waterproofing membrane should be installed with the non -woven side facing the applica- tor. CCW MiraCLAY product name is printed on the non- woven geotextile side. Create a cant at any vertical to horizontal transition by applying a 1.5" (39 mm) to 2" (50mm) of CCW MiraCLAY Granules along that junc- tion. At the base of the foundation wall where the verti- cal wall meets the horizontal footing, install a stripping Ply of CCW MiraCLAY out onto the horizontal plane and up the vertical wall a minimum of 6" (300 mm). Install the adjacent rolls of CCW MiraCLAY in a horizontal manner extending out onto the footing a minimum of 24" (600mm). Fasten the CCW MiraCLAY in place with concrete fasteners and 1" (25 mm) washers. Install suc- ceeding courses of CCW MiraCLAY by overlapping the previous course a minimum of 4" (100 mm). Stagger the seams a minimum of 12" (300 mm), Install in shingle fashion so that the upper roll of CCW MiraCLAY is over- laps the lower roll. Fasten membrane once every 2' "(60 cm) to 3' (90 cm) on seams or as required to prevent blousing. At grade line, terminate CCW MiraCLAY with a rigid termination bar or fasten 12" (300 mm) on center. Embed the top edge of CCW MiraCLAY and termina- tion bar with a thick bead of CCW MiraCLAY mastic 2" (50 mm) wide by 1/2" (12 mm) thick. DETAIL REQUIREMENTS For standard installation details, follow the CCW MiraCLAY details drawings. For non-standard installa- tion instructions contact your local Carlisle Coatings & -Waterproofing representative. - ---- RECOMMENDATIONS Carlisle Coatings & Waterproofing recommends the use Of CCW MiraDRAIN, a geocomposite sheet drain, to facilitate the removal of water away from the structure. The CCW MiraCLAY and CCW MiraDRAIN waterproof- ing and drainage system provides maximum protection against water penetration.

Stefan, Per your request I'm responding to your questions and proving you with photos of the area in question, which is 24'x19x 5" approximately 456 Sq ft. As well as floor plan indicating location within scope of work. As denoted by the engineer in his cover letter, submitted in original request for review you can see the size and spacing of rebar, as well as multiple vapor barriers, sand and use of CCW Miraclay system. I hope that this helps. Thank you, Jaime Ruiz 949.874.5363 19 I 1.1
