Watermill Place Condominiums - Arlington, MA

Property Manager:  Barrington Management Inc.           
Engineer:  CBI Consulting Inc.
General Contractor:  Alpha Weatherproofing Corp.      

CHALLENGE: 
The upper level carport at Watermill Place Condominiums had originally been waterproofed with a single-ply membrane that had failed and was allowing water to penetrate down through the topping slab and precast plank system onto vehicles parked on the lower level.

SOLUTION: 
The Alpha Weatherproofing team was called upon to install a waterproofing system.

PREPARATION

  • Reinforced plastic was erected under the slab to prevent leaking  or damage to cars
  • The topping slab was removed
  • The failed membrane was removed and the surface was prepped  using hydrodemolition

MEMBRANE WATERPROOFING

  • Cracks were saw cut, sealed and detailed
  • Waterproofing was applied with gage rakes to ensure the proper  mil thickness

TESTING 

  • Numerous moisture tests were performed to ensure positive application
  • Drains were plugged and a 24-hour water test was conducted

CONCRETE POUR

  • A special protection course/drainage mat was installed
  • 1.5-inch macro fiber reinforcement was added to the concrete to prevent cracking
  • Line stripes and brick walkways were installed to complete the project

Facility owners and residents were pleased that the parking area was successfully restored to a waterproof and worry-free condition.
