WATERPROOFING - CONCRETE PIT
 |
PROJECT: Process Pit Water Proofing OWNER: U.S. Environmental Protection Agency INSTALLER: Sure Seal, Inc. SYSTEM: POLYARMOR ® 444-370 COLOR: Black AREA: 35,000sq. ft. COMPLETED: 1996 |
DISCUSSION: This segmented, ten foot deep poured concrete pit was installed specifically for the purpose of reclaiming PCB contaminated soil.
PRONTO PRIME concrete primer was spray applied to the conccrete surface. The concrete was spray sealed with 80 mils. of POLYARMOR 444-370 plural component polyurea.
The sealing operation was commenced within 72 hours of the concrete pour...immediately following removal of the forms. This procedure was precedent-setting. It was carried out under the supervision of P. E. Civil Engineers in conjunction with oversight and recommendations by Visuron Technical Service.
No detrimental effects have been experienced with either the concrete or with the POLYARMOR polymer resulting from coating the three day old green concrete.
