Borehole Sanitary Seal Query
Dear Sir/Madam,
First time using this service.
I am looking to establish best practice in placing a sanitary seal to prevent shallow groundwater intrusion into a water supply borehole. The borholes are manual drilled.
Specifically looking at: • Mix ratios for cementitous grout • Issues with using aggregate • Requirements for curing • Placement below water table • Need for tremie pipe or rodding/compaction Any help would be appreciated.
