Geo-Seal® Case Studies

 

Project Name: Salvation Army Kroc Center

Location: Dayton, OH

Area: 100,000 Sq Ft


The  Salvation  Army  Kroc  Center  is  a  multi-million  dollar  community  complex  on  17.5  acres.  Dayton  was  one  of  29  cities to receive funding from the 1.1 billion dollar donation of the Ray Kroc Family for the development of community centers across the United States. Environmental concerns arose from a neighboring groundwater plume migrating from a former industrial  facility.

Project Name: Former Warehouse Redevelopment

Location: London U.K.

Area: 2,000 m2


A  2,000  m2  floor  space  of  a  vacant  building  in  London,  formerly  used  for  warehousing  and  storage,  was  to  be  redeveloped  into  a  number  of  start-up  business  premises.  High  benzene  soil  concentrations  from  a  historic  paintworks  on site required a high performance vapour barrier to  protect future building tenants.

Project Name: Manufacturing Facility

Location: York, PA

Area: 104,000 Sq Ft


A 104,000 square foot manufacturing facility required the use of a vapor barrier due to migrating chlorinated solvents in  groundwater  from  a  nearby  plume.    In  addition  to  the  vapor  barrier,  a  30  mil  battened  and  welded  PVC  sheet  was  also  specified for enhanced protection which required an extended installation time.

Project Name: Love Field Airline Facility

Location: Dallas, TX

Area: 55,000 Sq Ft


The Dallas Love Field airport originally opened in 1917 and has over 90 years of aviation use. A major airline decided to expand their current facilities at Love Field which included the construction of a new maintenance facility. An underground storage tank was discovered prior to construction and insufficient historical site records caused concern for potential indoor air vapor in the new building.  A vapor intrusion barrier was sought to protect the new structure from potential vapor intrusion and keep the project on schedule.

Project Name: Kent County Courthouse

Location: Dover, DE

Area: 55,000 Sq Ft


The  new  Kent  County  Courthouse  was  in  need  of  gas  vapor  mitigation  resulting  from  a  subsurface  contaminant  plume.  Originally,  a  spray-applied  asphalt/latex  membrane  for  gas  vapor  protection  was  specified  in  addition  to  a  bentonite product  for  waterproofing  protection.

Project Name: CVS Pharmacy

Location: Tallahassee, FL

Area: 3,000 Sq Ft


To  accommodate  a  planned  expansion,  CVS  acquired  an  adjoining  vacant  building  (approximately  3000  ft2)  which  formerly  operated  as  a  commercial  dry  cleaning  facility.  Site  investigations  revealed  chlorinated  solvent contamination  in  groundwater  beneath  the  building,  including  tetrachloroethene  (PCE)  and  trichloroethene (TCE).

Project Name: Student Housing

Location: Louisville, KY

Area: 142,000 Sq ft


Student  housing  was  to  be  constructed  in  Louisville,  KY  over  42  acres  of  vacant  Brownfield  property.  Chlorinated  solvents  were  discovered  in  the  subsurface  soil  and  groundwater  beneath  the  proposed  construction  area  and  caused  concern  over  potential  indoor  air  vapor  within  the  housing  complex.

Project Name: Shinsei Gardens

Location: Alameda, CA

Area: 22,000 Sq Ft


A  senior  housing  facility  was  constructed  over  an  existing  benzene  plume  creating  a  concern  over  high  levels  of  benzene  vapors.  Northgate  Environmental,  with  the  approval  of  the  California  Department  of  Toxic  Substances  Control  (DTSC),  selected  Geo-Seal®  to  mitigate  the vapor intrusion risk.

Project Name: Compass Bank

Location: Birmingham, AL

Area: 4000 Sq Ft


Compass  Bank  was  constructed  over  a  site  with  chlorinated  solvents  residing in the subsurface.  A  vapor  intrusion  membrane  was  sought  to  prevent  vapor intrusion  into  the  building  from  the  contamination  below.  Initially,  a  simple spray-applied  material  was  specified, however,  TGE  Resources requested  the use of Geo-Seal®.
