PART 3 - EXECUTION 3.1
EXAMINATION
07 16 14-3
A.
3.2
3.3
Examine all construction substrates and conditions under which waterproofing materials are to be installed. Do not proceed with the waterproofing application until unsatisfactory conditions are corrected.
PREPARATION A.
Protect adjacent surfaces not designated to receive waterproofing.
Substrate preparation: 1. Remove oil, grease, dirt, loose particles, remains of form oils, water repellents, rust or other coatings by high-pressure water blasting (>3000 psi), wet or dry sand blasting, or other mechanical means to produce surface profile ICRI CSP 3 to 5 for application of waterproofing. 2. Follow manufacturer's instructions to clean and prepare surfaces and seal cracks and joints. 3. Voids in concrete substrates: 1/4-inch (6 mm) diameter and larger, pre-treat with patching compound. Less than 1/4-inch (6 mm) diameter can be filled with a scratch coat of onecomponent waterproofing material.
Rinse surfaces to be waterproofed (excluding drywall or similar) with clean water to saturated surface dry (SSD) condition, with no standing water on horizontal surfaces.
INSTALLATION A.
Mix two-component waterproofing material in proportions recommended by manufacturer.
Specifier: choose applicable articles depending on type of project B.
Cavity fill, honeycombs & formtie holes: a. Fill voids at cleaned and prepared faulty construction joints, cracks, formtie holes, etc. with patching compound in mortar consistency flush to surface. b. Laminate patching compound in 2 to 3 layers as per manufacturer's instructions for larger spalled or honeycombed areas.
Taping horizontal and vertical construction joints and cracks (positive side waterproofing only): Install joint and crack sealing tape, embedded in waterproofing material as follows: 1. Apply two-component waterproofing material by brush in a six to seven inch (15 – 18 cm) wide strip coat centered over all joints, cracks, penetrations and changes of plane to be taped. 2. Immediately, while this coat is still wet, unroll joint sealing tape into the coating, smoothing out wrinkles and fish mouths and press the tape into the fresh waterproofing material. 3. Assure that the tape adheres to the under-laying coat after a waiting period of at least 4 hrs. 4. After testing adhesion apply two-component waterproofing material over the tape.
Sealing around PVC pipe penetrations: 1. Abrade (sand) PVC pipes and degrease with isopropanol or acetone. 2. Place sealing gasket over pipe and mark size of penetration, then cut out necessary opening (penetration). 2. Apply one prime coat two-component waterproofing material over concrete and exposed PVC pipe. 3. While this coat is still wet, immediately place and firmly press sealing gasket into the coating. 4. Assure that the sealing gasket adheres to the under-laying coat after a waiting period of at least 4 hrs. 5. After testing adhesion apply two-component waterproofing material over the sealing gasket.
Positive Side Waterproofing: Apply two-component waterproofing material in quantities and number of coats as per manufacturer's specifications and recommendations: 1. Apply at 60 mils or 1/16” (1.5 mm) total thickness for all standard applications (i.e. foot traffic, balconies (non-tiled), etc.) and waterproofing up to 13 ft (4.0 m) water head. 2. Apply at 80 - 90 mils (2.0 - 2.4 mm) total thickness for applications exposed to hydrostatic pressure (>13 ft (>4.0 m) water head), under tiles, plaza decks, etc.

3.4
3.5
Surface Finish: 1. Surface finish shall be standard two-component waterproofing material finish (i.e. brush, trowel, roller or spray finish).
G.
Alternative I: Negative Side Waterproofing: Follow manufacturer’s specifications and instructions for below grade structures where infiltration from ground water is expected: 1. Apply base coat one-component waterproofing material at 60 mils (1.6 mm) thickness. Apply in two coats. 2. After 24 hrs waiting period, apply top coat two-component waterproofing material at 60 mils (1.6 mils). Apply in two coats.
H.
Alternative II: Horizontal surfaces with protective clear acrylic sealer: a. 1 coat application: 200 – 300 sq.ft./gal (4.9 – 7.4 m2/L. b. 2 coat application: 350 – 450 sq.ft./gal (8.6 – 11.0 m2/L.
I.
Application considerations: 1. Apply, using stainless steel trowel, tampico brush, short nap roller, or appropriate compressed-air spray equipment. 2. Apply only when surface and ambient temperatures are 40oF (5oC) and rising. At high temperatures (i.e. 86oF (30oC) and above) protect application from direct sun and wind to prevent premature surface drying and shrinkage cracks. Apply material in two coats minimum. 3. Application thickness should not exceed 1/8-inch (120 mils (3 mm)). 4. If needed, such as in zones posed to movement or cracking, plaza decks, etc., the waterproofing material can be additionally reinforced with a reinforcing mesh (supplied by waterproofing manufacturer), embedded between two waterproofing layers. 5. Do not bridge cracks greater than 1/16-inch (1.5 mm). 6. Bridge dynamic cracks or joints with elastomeric joint sealing tape, as supplied by waterproofing manufacturer. However, where aesthetics are important use an elastomeric sealant in lieu of the tape. 7. Do not overcoat waterproofing material with solvent-based materials. 8. Where a uniform color is desired (i.e. balconies, walkways, etc.), application of an elastomeric paint or water based acrylic stain is recommended. 9. Prime and protect alkali sensitive metals such as copper, aluminum, galvanized or zinc treated metal first with a primer, before over-coating with waterproofing material. Follow manufacturer’s recommendations for primer material.
CURING A.
Follow manufacturer's general instructions for curing and hardening of waterproofing material. Do not use water for curing. Waterproofing material is self-curing.
Protect surfaces from rain, frost and premature dehydration.
TESTING OF WATER INCLUDING STRUCTURES A.
3.6
Following application and completion of related work, as required, but well prior to completion of entire project, fill tanks to capacity and allow to be filled not less than 3 days. Fill larger structures at a uniform rate not greater than 6.5 feet (2 m) in 24 hours. The temperature of the fill water shall be plus or minus 10 degrees F of the ambient air and/or the tank structure at the time of filling. Extreme caution is urged if the temperature is greater than 10 degree F. Should leakage occur after this period, drain tanks to perform repairs. Notify Owner prior to draining tanks.
ACCEPTANCE A.
Remove left over materials and any foreign material resulting from the work from the site.
Clean adjacent surfaces and materials. END OF SECTION
