Does this look like your factory or warehouse floor or your external paving?

Typically, concrete floors in factories and warehouses require repair due to:

• Forklift damage
• Cracking
• Joint failure
• Surface delamination, scaling, dusting
• Sub-base subsidence, wash-outs, voids
• Chemical damage
• Design issues
• Wear and tear

If your factory or warehouse floors are affected by any of these issues then FCS Concrete Repairs have the experience and expertise to investigate, test, diagnose and recommend the most cost effective course of action to repair the floor and mitigate any further deterioration or future damage.

Concrete floors suffer this damage due to a large number of contributing causes:

• Forklift damage to floor joints and floor areas
• Heavy Loading damage to floors
• Failure when design limits are exceeded
• Subsidence of the sub-base
• Washout of the sub-base
• Poorly compacted sub-base
• Structural cracking
• Cold storage damage to floors
• Machinery loading on floors
• Machinery vibration impacts
• Concrete dusting
• Concrete wear and tear
• Rusting of internal reinforcement steel
• Potholes
• Floor demarcation line and safety marking wear
• Ingress of water
• Chemical damage
• Ground movement
• Stress loadings
• Temperature changes
• Product contamination of floor surface
• Delamination of concrete toppings
• Surface scaling
• Deterioration of applied coatings
• Plastic shrinkage cracking
• Overworking of surface during concrete placing
• Inadequate curing
• Premature surface sealing during concrete placing
• Improper concrete compaction
• Excessive moisture loss during concrete placing
• Poor structural design

It is important to determine the root cause of the concrete failure and develop a strategy to remedy the cause and complete an effective repair with a minimum of disruption to operations by delivering the best possible outcome.

Identifying the source: To pinpoint the sources of the problem, the contractor’s crew flooded the existing sinkholes and monitored the dry manhole to see where the infiltration entered.

Solution: With on-site technical support from Prime Resins, the contractor injected Prime Flex 920 through the manhole wall to fill the voids and create a watertight curtain around the manhole. Prime Flex 920 is an expansive, hydrophobic polyurethane resin that reacts to form a rock-hard watertight mass. The grouting was done from inside the manhole because the repair locations were so deep, as much as 20 feet from the surface. Probe grouting from the surface outside the manhole can be done if the manhole is too narrow to work within.

They installed four injection ports per pipe and injected each leak location starting at the lowest point and working up. This revealed a leaking injection hole from the previous repair attempt. Some 920 seeped out this hole and sealed it as well. The technicians repaired wide gaps around the main connection plus spalls and chips inside the collar using the activated oakum technique. They soaked oil-free oakum with Prime Flex 900 XLV and pushed it into the gaps where the reacted resin sealed the openings. The 900 XLV is a very low viscosity polyurethane and is hydrophilic, so it creates a tenacious bond with the wet concrete.

Outcome: The crew tested their repair by flooding the sinkhole again. No water drained into the manhole: their repairs stopped the infiltration. Finally, they removed the ports and plugged the holes with hydraulic cement.
