Challenge
To meet the parking requirements for the project, the lowest parking level had to be constructed eight feet below the existing water table, necessitating a solution capable of withstanding high hydrostatic pressure.
Solution
Hycrete360 (formerly System W) offered superior performance to other waterproofing systems, was more cost-effective and accelerated the construction schedule. Using Hycrete360 eliminated the need for waterproofing membranes and saved Sellen Construction approximately $150,000 up front in material savings. 
Material Savings
Time Savings
Result
Total material and time savings are $450,765. On top of CO2 savings associated with eliminating de-watering pumps, eliminating waterproofing membranes saved over 33,000 pounds of landfill waste, 16,000 pounds of asphalt, 1,100 pounds of VOCs (volatile organic compounds), and 62,000 square feet of non-renewable materials.
