Warehouse Floor Water Intrusion Repair

produce facility floor repair using chemical grouting to stop water intrusion through joints

Challenge:

An area of floor inside of a produce processing facility experienced water intrusion through joints in the floor.  Considerable amounts of process water were dumped on the floor each day, and unsealed joints in the floor allowed water to collect under the floor slab.  With dynamic loading from material handling equipment, water was displaced through the joint onto the floor.  The facility’s health & safety  staff was concerned that the water could introduce contaminants to the food processing area.

Undersealing the produce warehouse floor.

Limits:

The proposed repair had to perform well in saturated conditions, allow for near immediate resumption of material handler equipment, and ensure a longterm fix.  Since no settlement had occurred, the grout material had to be able to seal the very small voids, displace water, and not exert any lifting forces on the floor.

The material & process also had to be performed at cold temperatures–the facility is maintained at 34 degrees year-round.

The Solution:

CJGeo proposed chemical grouting using a hydrophilic prepolymer grout.  Chemical grouting is ideal for saturated environments and helps to ensure complete stabilization and sealing of floors.  

Result:

A single CJGeo chemical grouting crew mobilized to South Carolina and performed the work in a few hours.  The work started after second shift, and was completed in time for the grout to set and tolerate material handling equipment at the start of first shift.

The following day, the facility reported no water extrusion under material handler traffic.
