WATERPROOFING GENERAL NOTES

1. WATERPROOFING WORK INDICATED CONSISTS OF A BASE SCOPE OF WORK, AND

ALTERNATE WORK - REFER TO THE DRAWINGS FOR DESCRIPTIONS. ALTERNATE WORK IS

SUBTRACTIVE FROM THE BASE SCOPE, AND IN LIEU OF BASE SCOPE.

2. COMPLETE WATERPROOFING IN SEQUENCE AFTER COMPLETION OF SELECTIVE

DEMOLITION AND WALL INFILLS AND REPAIRS INDICATED IN THE ARCHITECTURAL

DRAWINGS, AND AFTER INSTALLATION OF ALL EQUIPMENT, SERVICES, PIPING, AND

SIMILAR WORK PENETRATING THROUGH AREAS SCHEDULED TO RECEIVE

WATERPROOFING.

3. LIMIT EXCAVATION EXTENTS FOR WATERPROOFING TO THE EXTENT POSSIBLE TO ACCESS

THE WORK AREAS. AVOID DISTURBANCE OF ADJACENT EXISTING-TO-REMAIN SITE

FEATURES WHEREVER POSSIBLE.

4. AFTER EXCAVATION, INJECT RESIN WATERPROOFING INTO ALL EXPOSED CRACKS AND

CONSTRUCTION COLD JOINTS IN EXISTING CONCRETE SHELTER ROOF AND WALLS WITHIN

THE WATERPROOFING WORK AREA PER WATERPROOFING MANUFACTURER

RECOMMENDATIONS.

5. PREPARE EXISTING CONCRETE AND MASONRY SUBSTRATES PER RECOMMENDATION OF

WATERPROOFING MANUFACTURER AS NECESSARY FOR WATERPROOFING INSTALLATION.

AT AREAS OF ADHERED WATERPROOFING, FILL VOIDS AND REMOVE RIDGES TO ACHIEVE A

SMOOTH UNIFORM SUBSTRATE, AND REMOVE ALL BOND-INHIBITING SUBSTANCES.

6. ALL WATERPROOFING THAT PROTRUDES ABOVE FINISHED GRADE SHALL BE FULLY

CONCEALED AND PROTECTED WITH COUNTERFLASHING EXTENDING DOWN BELOW

FINISHED GRADE AS INDICATED IN DETAILS.

7. AFTER COMPLETION OF WATERPROOFING, BACKFILL AREAS EXCAVATED FOR

WATERPROOFING, APPLY TOPSOIL, RE-GRADE, AND RE-SOD / RESTORE EXISTING

LANDSCAPING AS INDICATED IN THE CIVIL AND ARCHITECTURAL DRAWINGS.

8. REFER TO THE CIVIL DRAWINGS FOR ADDITIONAL SITEWORK ADJACENT TO THE

WATERPROOFING AND ELSEWHERE ON THE SITE THAT IS NOT SHOWN IN THESE

WATERPROOFING DRAWINGS.

9. REFER TO THE CIVIL DRAWINGS FOR ADDITIONAL INFORMATION ON THE PERIMETER

DRAIN SYSTEM INDICATED IN THESE WATERPROOFING DRAWINGS, AND FOR PIPING AND

CONNECTION OF THE PERIMETER DRAIN SYSTEM TO THE EXISTING CATCHBASIN.

10. REFER TO THE CIVIL DRAWINGS FOR ADDITIONAL INFORMATION ON EXCAVATION,

BACKFILLING, TOPSOIL, ROUGH AND FINISHED GRADING, AND SOD / LANDSCAPING

REQUIREMENTS FOR AREAS EXCAVATED FOR WATERPROOFING.

11. REFER TO THE ARCHITECTURAL, STRUCTURAL, AND M/E/P DRAWINGS FOR ADDITIONAL

WORK TO THE EXISTING BUILDING, EQUIPMENT CORRAL, AND SITE THAT IS NOT SHOWN

ON THESE WATERPROOFING DRAWINGS.
