Concrete Coring/Repair and Asphalt Repair 

​We provide concrete coring, cutting and repair services with  minimal disruption to your job site and operations.

Well Development

Using our Positive Air Displacement  (PAD) development system we can develop new wells or re-develop wells at a fraction to the price of most drilling companies.



We use multiple PAD systems capable of gently moving large volumes of silt and sediment from the well bottom.  All air used to displace water and sediment is contained within the pump so there is no danger of injection air into the screen.  We also have the capability to develop wells with electric submersible pumps and/or stainless steel slurry bailers.


 

Well Video Inspection

Our down hole video unit can be deployed up to 1000 feet.  It transmits a beautiful color picture with the deployment depth displayed on the viewing monitor.  All footage is digitally recorded and can be delivered via DVD or thumb drive, or uploaded to a viewing server.  Video inspections are great for:



- Bore hole inspection

- Well inspection

- Well construction confirmation

- Obstruction observation

- Screen inspection


 

Well Abandonment

​From pressure grouting to over drilling we provide customized services to meet your specific site and agency requirements. 

Well head Repair

Unsecured well box lids and degraded concrete aprons can create risky health and safety situations for field employees and the general public.  Additionally, preventative maintenance can reduce the risk of costly emergency repairs.



Confluence Environmental combines extensive construction and groundwater sampling experience so repairs are made while paying special attention to the sensitive nature of monitoring wells.  We have experience managing maintenance programs for small and large portfolios for regional consulting firms and leading international oil companies.  Our proactive approach to repairs is proven to keep sites safe and within strict compliance requirements.
