Groundwater remediation means actions that are necessary to prevent, minimize, clean up, or mitigate damage to groundwater. This process is used in the removal of dissolved contaminants from the subsurface and containment of contaminated groundwater to prevent migration. This process consists of defining the remedial action objectives to be accomplished at the site. This involves gathering enough background information and field data to assess remedial requirements and possible cleanup levels. This process enables physical, chemical, or biological in situ treatment of contaminated groundwater by means of reactive materials. The most commonly used processes/reactions are: redox reactions, precipitation, adsorption, ion exchange and biodegradation. The reactive materials are placed in undergound trenches downstream of contamination plume, forcing it to flow through them. By doing so, the contaminants are treated without soil excavation or water pumping.

Grouser bar rebuilder is used for continuous sequenced rebuilding process. It contains three workstations each station is 48″ wide to handle most, but not all size of pads. Primary clamping station, which uses shop air, is capable of 80,000 lb. of clamping force. Clamp mechanism is enclosed for safety and reduced maintenance. Cutting and finish weld stations have convenient foot-operated clamps. Water quench of slag and molten metal under flame cutting station provides maximum safety for operator as well as for entire work area.

Grout colorant is an aqueous modified epoxy emulsion designed for use on cementitious grouts as well as epoxy grout systems. It is generally recommended for ceramic and porcelain tile installations, but can be used on natural stone installations as well. It also re-colors, seals and rejuvenates existing grout joints.
