    • Delaminated Concrete Topping Repair
    • Grated Drain Repair

    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.

    FCS Concrete Repairs have a strong knowledge base to ensure that any repairs are effective.

    Case Study: Sealing a manhole with chemical grout

    October 2nd, 2017 Posted by Blog, Concrete Repair, Featured Case Study, manhole rehabilitation, Projects 0 thoughts on “Case Study: Sealing a manhole with chemical grout”

    Problem: Sinkholes had developed around storm drainage manholes in grassy areas of a military housing subdivision in Richmond, Virginia.

    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.

    Eroding Soil Could Lead to Cave In Underneath Busy Intersection

    Eroding Soil Could Lead to Cave In Underneath Busy Intersection

    Hi Ray,

    Ever worry about the ground collapsing out from under your car while you’re waiting at a red light?  Perhaps you should.  Here’s a story that should serve as a wake up call to us all…

    Recently, county inspectors found a depression in a road – due to an underground sewer line that wasn’t sealed – at a heavily trafficked roadway intersection in Orange County, Florida.  Water and eroding soil were infiltrating the sewer line causing the road to slowly settle.  The resulting voids around the drainage structures had the potential to grow larger, eventually resulting in a complete cave-in of the roadway.  In this particular case, there was a patch of asphalt 12’ x 25’ that was settling and officials feared a cave-in would occur.  A point repair was done from within the leaky pipe to stop the infiltration but they feared it was only a matter of time before the road gave way. It was going to be very difficult and inconvenient to dig up this roadway, fill the void, re-compact, and re-pave due to the high volume of traffic, the adjoining rail crossing, as well as several major utilities running through the area.  Not to mention that the area would have to be completely shut down to accommodate all of the equipment required for such a repair.

    Powerful Polymer

    Orange County approached Alchemy-Spetec to see if we could come up with a powerful, painless and rapid solution using chemical grouting to fill the voids and stabilize the roadway. We devised a solution for them using the versatility of AP Fill 700 as both a permeation and void filling grout.

    Painless Procedure

    We advised their crew to lay out a grid on the settling asphalt area and set up injection points to drive pipes down to the 13’ depth where leaking had occurred and where the loose soil zone was located.

    They monitored the pipes while injecting material at a rate of 2 gallons per vertical foot through the open manhole to identify additional leaks that had been missed during the first point repair.  As expected when foam was observed coming in through a leaking joint it quickly sealed off the leak at the same time it was stabilizing the soil.

    Rapid Result

    To keep the lane closure down to a bare minimum of time, the project was successfully completed on two separate Saturdays.  The voids were filled, the loose soil was solidified, and now only minor asphalt patching will be required to make that area smooth for traffic again.
