FLUID-APPLIED WATERPROOFING SYSTEMS: A CASE STUDY OF KILEY GARDENS By SARAH VASCONI A THESIS PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN BUILDING CONSTRUCTION UNIVERSITY OF FLORIDA 2009 © 2009 Sarah Vasconi 2 To my parents, especially my mother for all the love and support she has given me over the years. I know that she is proud of me, and in whatever I choose to do in life I know I will have success because I have her behind me. To Thomas, because my accomplishments never quite seem so amazing till he tells me so. I don‘t know what I would do without him. And finally to my dog Molly, for she will always look adoringly up at me and was there every day, sitting at my feet, while I wrote this. 3 ACKNOWLEDGMENTS I thank my supervisory chairs and lab technicians for all their help in this tedious thesis process. In addition, my work would not have been able to be completed without the help of the manufactures‘ representatives who supplied me with samples of waterproofing products. I know that in the course of their work, they did not need to help me out so selflessly, and it shows me that in this business it is better to make friends, because you never know what type of favor you might need to ask. 4 TABLE OF CONTENTS page ACKNOWLEDGMENTS ...............................................................................................................4 LIST OF TABLES
