PRE-CONSTRUCTION CONFERENCES: THE MANUFACTURER WILL MEET WITH THE NECESSARY PARTIES
AT THE JOBSITE TO REVIEW AND DISCUSS PROJECT CONDITIONS AS IT RELATES TO THE INTEGRITY OF
THE WATERPROOFING ASSEMBLY.
DELIVERY, STORAGE AND HANDLING: DELIVER MATERIALS IN ORIGINAL UNOPENED CONTAINERS OF
PACKAGING CLEARLY LABELED WITH MANUFACTURER'S NAME, BRAND NAME, INSTRUCTION FOR USE
AND ALL IDENTIFYING NUMBERS. MATERIALS SHALL BE STORED IN A NEAT, SAFE MANNER, NOT TO
EXCEED THE ALLOWABLE STRUCTURAL CAPACITY OF THE STORAGE AREA. STORE MATERIALS IN A
CLEAN, DRY AREA PROTECTED FROM WATER AND DIRECT SUNLIGHT. STORE ALL ADHESIVES AT
TEMPERATURES BETWEEN 60°F (15.5°C) AND 80°F (26.6°C). IF EXPOSED TO LOWER TEMPERATURES,
RESTORE MATERIALS TO 60°F (15.5°C) MINIMUM TEMPERATURE BEFORE USING.
PROJECT CONDITIONS: APPLICATION OF THE MEMBRANE SHALL NOT COMMENCE NOR PROCEED
DURING INCLEMENT WEATHER. ALL SURFACES TO RECEIVE THE MEMBRANE SHALL BE FREE OF
WATER, DEW, FROST, SNOW AND ICE. APPLICATION OF MM6125-FR SYSTEM SHALL NOT COMMENCE NOR
PROCEED WHEN THE AMBIENT TEMPERATURE IS BELOW 0°F. APPLICATION OF ULTRA SYSTEM SHALL
NOT COMMENCE NOR PROCEED WHEN AMBIENT TEMERATURE IS BELOW 40°F. DO NOT ALLOW WASTE
PRODUCTS (PETROLEUM, GREASE, OIL, SOLVENTS, VEGETABLE OR MINERAL OIL, ANIMAL FAT, ETC.) TO
COME IN CONTACT WITH THE MEMBRANES. ANY EXPOSURE TO FOREIGN MATERIALS OR CHEMICAL
DISCHARGES MUST BE PRESENTED TO MEMBRANE MANUFACTURER FOR EVALUATION TO DETERMINE
ANY IMPACT ON THE WATERPROOF MEMBRANE ASSEMBLY PERFORMANCE.
INSPECTION: CONCRETE DECK/WALL SURFACE CONDITION: SHALL BE CLEAN, FREE OF EXISTING
WATERPROOFING AND DEBRIS, ASSURE ADEQUATE PROTECTION DURING INSTALLATION OF THE
WATERPROOFING ASSEMBLY. THE WATERPROOFING CONTRACTOR SHALL EXAMINE ALL SURFACES TO
RECEIVE THE WATERPROOFING ASSEMBLY TO VERIFY IT IS ACCEPTABLE AND PROPER FOR THE
APPLICATION OF THE MEMBRANE USING THE AMERICAN HYDROTECH'S PRE-INSTALLATION &
APPLICATION GUIDELINES. THE WATERPROOFING CONTRACTOR SHALL NOT PROCEED WITH THE
INSTALLATION OF THE WATERPROOF MEMBRANE ASSEMBLY UNTIL ALL DECK DEFECTS HAVE BEEN
CORRECTED.
PREPARATION: ALL SURFACES MUST BE DRY, SMOOTH, FREE OF DEPRESSIONS, VOIDS, PROTRUSIONS,
CLEAN AND FREE OF UNAPPROVED CURING COMPOUNDS, FORM RELEASE AGENTS AND OTHER SURFACE
CONTAMINANTS. CONCRETE DECK MUST BE MONOLITHIC, SMOOTH, FREE OF VOIDS, SPALLED AREAS,
LAITANCE, HONEYCOMBS, AND SHARP PROTRUSIONS.
TEST PATCHES: THE MEMBRANE APPLICATION SHALL PROCEED ONLY AFTER THE SUCESSFUL
COMPLETION OF TEST PATCH TO CHECK THE ADHESION OF THE MEMBRANE. APPLY A TEST PATCH OF
MONOLITHIC MEMBRANE 6125 TO THE SURFACE AND CHECK ITS ADHESION PER THE INSTALLATION
GUIDELINES OF AMERICAN HYDROTECH.
INSTALLATION OF SURFACE CONDITIONER: THE USE OF SURFACE CONDITIONER TO THE EXISTING WALL
SURFACES AND CONCRETE SHOULD DETERMINED. CONFIRMATION OF THIS SHALL BE DETERMINED BY
THE MANUFACTURER. IF CONDITIONER IS DEEMED APPROPIATE BY THE MANUFACTURER, USING A
HAND HELD SPRAYER EVENLY AT A RATE OF 300 TO 600 SF/GALLON DEPENDING ON SURFACE TEXTURE.
SURFACE CONDITIONER SHOULD "TAN" THE SURFACE, NOT BLACKEN IT. ALLOW SUFFICIENT TIME FOR
THE SURFACE CONDITIONER TO THOROUGHLY DRY PRIOR TO THE MEMBRANE APPLICATION.
INSTALLATION OF THE HOT, LIQUID-APPLIED MEMBRANE: THE MEMBRANE SHALL BE HEATED IN
DOUBLE JACKETED, OIL BATH OR HOT AIR MELTER WITH MECHANICAL AGITATION, SPECIFICALLY
DESIGNED FOR THE PREPARATION OF A RUBBERIZED ASPHALT MEMBRANE. HEAT MEMBRANE UNTIL
MEMBRANE CAN BE DRAWN-FREE FLOWING AT A TEMPERATURE RANGE BETWEEN 350°F AND 375°F.
MEMBRANE EXCEEDING 400°F SHALL NOT BE USED AND SHALL BE PROPERLY DISPOSED OF. ALL
DETAILING AND FLASHING SHALL BE DONE IN ACCORDANCE WITH THE MANUFACTURER'S STANDARD
GUIDELINE DETAILS AND THESE DRAWINGS. ALL DETAILING AND FLASHING SHALL BE COMPLETED
BEFORE INSTALLING THE MEMBRANE OVER THE FIELD OF THE SUBSTRATE. APPLY THE RUBBERIZED
ASPHALT MEMBRANE AT A RATE TO PROVIDE A CONTINUOUS, MONOLITHIC COAT OF 215 MIL MINIMUM,
BUT NOT LESS THAN 180 MIL THICKNESS. INSTALL ULTRA SHEET WATERPROOFING FLASHING AT EDGES
AND TERMINATIONS AS SHOWN IN THE DETAILS PRIOR TO INSTALLATION OF THE PROTECTION SHEET
TO ENSURE MEMBRANE-TO-MEMBRANE ADHESION. EMBED THE PROTECTION SHEET INTO THE
MEMBRANE WHILE IT IS STILL HOT TO INSURE A GOOD BOND. OVERLAP ADJOINING SHEET EDGES (DRY)
A MINIMUM OF 2"-3" (50.8 MM - 76.2 MM) TO INSURE COMPLETE COVERAGE. INSTALL RIGID PROTECTION
BOARD OVER EMBEDDED PROTECTION SHEET, STAGGER THE JOINTS AND INSTALL 90 DEGREES TO THE
PROTECTION SHEET.
WATER TEST: THE WATERPROOFING APPLICATION SHALL SUCESSFULLY PASS A 48 HOUR WATER TEST.
THE TEST SHALL BE AS FOLLOWS: FOR EACH DECK POND WATER TO A MINIMUM DEPTH OF 2" FOR A
PERIOD OF 48 HOURS TO CHECK THE INTEGRITY OF THE MEMBRANE INSTALLATION.
DRAINAGE COURSE: INSTALL DRAINAGE COURSE ON HORIZONTAL AND VERTICAL SURFACES IN
ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS. LAYOUT AND POSITION DRAINAGE
COURSE AND ALLOW TO LAY FLAT. CUT AND FIT DRAINAGE COURSE TO PERIMETER AND
PENETRATIONS.
WARRANTY: 10-YEAR WATERTIGHTNESS WARRANTY (JOINT LABOR AND MATERIALS)
