Do not proceed with the waterproofing application until unsatisfactory conditions are <br />corrected.</p> <p>PREPARATION <br />A.</p> <p>Protect adjacent surfaces not designated to receive waterproofing.</p> <p>B.</p> <p>Substrate preparation: <br />1. <br />Remove oil, grease, dirt, loose particles, remains of form oils, water repellents, rust or other <br />coatings by high-pressure water blasting (>3000 psi), wet or dry sand blasting, or other <br />mechanical means to produce surface profile ICRI CSP 3 to 5 for application of waterproofing. <br />2. <br />Follow manufacturer's instructions to clean and prepare surfaces and seal cracks and joints. <br />3. <br />Voids in concrete substrates: 1/4-inch (6 mm) diameter and larger, pre-treat with patching <br />compound. Less than 1/4-inch (6 mm) diameter can be filled with a scratch coat of onecomponent waterproofing material.</p> <p>C.</p> <p>Rinse surfaces to be waterproofed (excluding drywall or similar) with clean water to saturated surface <br />dry (SSD) condition, with no standing water on horizontal surfaces.</p> <p>INSTALLATION <br />A.</p> <p>Mix two-component waterproofing material in proportions recommended by manufacturer.</p> <p>Specifier: choose applicable articles depending on type of project <br />B.</p> <p>Cavity fill, honeycombs & formtie holes: <br />a. <br />Fill voids at cleaned and prepared faulty construction joints, cracks, formtie holes, etc. <br />with patching compound in mortar consistency flush to surface. <br />b. <br />Laminate patching compound in 2 to 3 layers as per manufacturer's instructions for <br />larger spalled or honeycombed areas.</p> <p>C.</p> <p>Taping horizontal and vertical construction joints and cracks (positive side waterproofing only): <br />Install joint and crack sealing tape, embedded in waterproofing material as follows: <br />1. <br />Apply two-component waterproofing material by brush in a six to seven inch (15 – 18 cm) wide <br />strip coat centered over all joints, cracks, penetrations and changes of plane to be taped. <br />2. <br />Immediately, while this coat is still wet, unroll joint sealing tape into the coating, smoothing out <br />wrinkles and fish mouths and press the tape into the fresh waterproofing material. <br />3. <br />Assure that the tape adheres to the under-laying coat after a waiting period of at least 4 hrs. <br />4. <br />After testing adhesion apply two-component waterproofing material over the tape.</p> <p>D.</p> <p>Sealing around PVC pipe penetrations: <br />1. <br />Abrade (sand) PVC pipes and degrease with isopropanol or acetone. <br />2. <br />Place sealing gasket over pipe and mark size of penetration, then cut out necessary opening <br />(penetration). <br />2. <br />Apply one prime coat two-component waterproofing material over concrete and exposed PVC <br />pipe. <br />3. <br />While this coat is still wet, immediately place and firmly press sealing gasket into the coating. <br />4. <br />Assure that the sealing gasket adheres to the under-laying coat after a waiting period of at <br />least 4 hrs. <br />5. <br />After testing adhesion apply two-component waterproofing material over the sealing gasket.</p> <p>E.</p> <p>Positive Side Waterproofing: <br />Apply two-component waterproofing material in quantities and number of coats as per <br />manufacturer's specifications and recommendations: <br />1. <br />Apply at 60 mils or 1/16” (1.5 mm) total thickness for all standard applications (i.e. foot traffic, <br />balconies (non-tiled), etc.) and waterproofing up to 13 ft (4.0 m) water head. <br />2. <br />Apply at 80 - 90 mils (2.0 - 2.4 mm) total thickness for applications exposed to hydrostatic <br />pressure (>13 ft (>4.0 m) water head), under tiles, plaza decks, etc.</p> <p>07 16 14-4</p> <p>Flexible Cementitious Waterproofing</p> <p>3.4</p> <p>3.5</p> <p>F.</p> <p>Surface Finish: <br />1. Surface finish shall be standard two-component waterproofing material finish (i.e. brush, trowel, <br />roller or spray finish).</p> <p>G.</p> <p>Alternative I: Negative Side Waterproofing: <br />Follow manufacturer’s specifications and instructions for below grade structures where <br />infiltration from ground water is expected: <br />1. <br />Apply base coat one-component waterproofing material at 60 mils (1.6 mm) thickness. Apply <br />in two coats. <br />2. <br />After 24 hrs waiting period, apply top coat two-component waterproofing material at 60 mils <br />(1.6 mils). Apply in two coats.</p> <p>H.</p> <p>Alternative II: Horizontal surfaces with protective clear acrylic sealer: <br />a. <br />1 coat application: 200 – 300 sq.ft./gal (4.9 – 7.4 m2/L. <br />b. <br />2 coat application: 350 – 450 sq.ft./gal (8.6 – 11.0 m2/L.</p> <p>I.</p> <p>Application considerations: <br />1. <br />Apply, using stainless steel trowel, tampico brush, short nap roller, or appropriate <br />compressed-air spray equipment. <br />2. <br />Apply only when surface and ambient temperatures are 40oF (5oC) and rising. At high <br />temperatures (i.e. 86oF (30oC) and above) protect application from direct sun and wind to <br />prevent premature surface drying and shrinkage cracks. Apply material in two coats minimum. <br />3. <br />Application thickness should not exceed 1/8-inch (120 mils (3 mm)). <br />4. <br />If needed, such as in zones posed to movement or cracking, plaza decks, etc., the <br />waterproofing material can be additionally reinforced with a reinforcing mesh (supplied by <br />waterproofing manufacturer), embedded between two waterproofing layers. <br />5. <br />Do not bridge cracks greater than 1/16-inch (1.5 mm). <br />6. <br />Bridge dynamic cracks or joints with elastomeric joint sealing tape, as supplied by <br />waterproofing manufacturer. However, where aesthetics are important use an elastomeric <br />sealant in lieu of the tape. <br />7. <br />Do not overcoat waterproofing material with solvent-based materials. <br />8. <br />Where a uniform color is desired (i.e. balconies, walkways, etc.), application of an elastomeric <br />paint or water based acrylic stain is recommended. <br />9. <br />Prime and protect alkali sensitive metals such as copper, aluminum, galvanized or zinc <br />treated metal first with a primer, before over-coating with waterproofing material. Follow <br />manufacturer’s recommendations for primer material.</p> <p>CURING <br />A.</p> <p>Follow manufacturer's general instructions for curing and hardening of waterproofing material. Do not <br />use water for curing. Waterproofing material is self-curing.</p> <p>B.</p> <p>Protect surfaces from rain, frost and premature dehydration.</p> <p>TESTING OF WATER INCLUDING STRUCTURES <br />A.</p> <p>3.6</p> <p>Following application and completion of related work, as required, but well prior to completion of entire <br />project, fill tanks to capacity and allow to be filled not less than 3 days. Fill larger structures at a uniform <br />rate not greater than 6.5 feet (2 m) in 24 hours. The temperature of the fill water shall be plus or minus <br />10 degrees F of the ambient air and/or the tank structure at the time of filling. Extreme caution is urged <br />if the temperature is greater than 10 degree F. Should leakage occur after this period, drain tanks to <br />perform repairs. Notify Owner prior to draining tanks.</p> <p>ACCEPTANCE <br />A.</p> <p>Remove left over materials and any foreign material resulting from the work from the site.</p> <p>B.</p> <p>Clean adjacent surfaces and materials. <br />END OF SECTION</p> <p>Project: ........
