This method of repair is applied in multiple situations. Examples of these situations are: new construction joints with no joint filler, older constructions joints where the filler is deteriorating and/or falling out, and random cracks throughout the slab that need immediate attention.
Initially, our industry-leading repairs include removal of pre-existing joint filler, if needed. Next, through our methods, we reconstruct a new joint. By doing so, we are able to install the appropriate joint filler.
Construction joints and random cracks are typically the first areas of concern that are addressed by facility managers. By addressing these needs, you can immediately create a safer work environment while reducing equipment damages.
Construction Joint/Crack Repair
If slab curl has taken place, or if settling of substrate has occurred, the void created between the substrate and the concrete panels must be addressed to avoid further floor issues. FCI has developed a streamlined process to solve these problems in a short amount of time compared to techniques used in the past.
Using a highly expansive polyurethane foam, the problematic voids can be filled, ceasing any vertical movement of the slab. The fast reacting foam will have your floor ready for heavy traffic in less than an hour.
Major Joint Reconstruction
Without proper protection, a construction joint may deteriorate to the point where a major repair must be made. If neglected, these joints can easily cause high-cost damage to equipment as well as create a less-safe work environment.
By removing all the damaged concrete to a depth of more than one inch and replacing it with a repair mortar made of high-strength epoxy, the construction joint can return to like-new condition.
FCI prides itself on its ability to make these typically invasive repairs quickly, minimizing any disruption to logistics.
For numerous reasons, construction joints can become unlevel over time, creating a lip from one concrete panel to the next.
Using top-of-the-line floor equipment, FCI can repair these joints, restoring the joint's profile back to even by grinding the concrete on the "high side" to match the "low side".
This process is typically made concurrently with other repairs, reducing the disruption to your facility
Why your floors are failing
Slab Curl - Slab Curl is caused by uneven drying during the initial curing. Moisture escape from the surface of the concrete, whle it remains damp on the underside of the slab. This causes the slab edges to curl upwards.In many instances, this will lift the slab off of the compacted substrate below. In turn, slab curl will cause uneven panels, rocking panels and dislodging of joint filler. The panels can also crack and return back to the substrate.
Slab Shrinkage - As the concrete cures, the slabs will shrink. In many cases this will allow the joint filler to fall down below the surface. This exposes your joint edges to damage from wheeled traffic.
Lack of Maintenance - As floors age, the joint filler and joint edges begin to wear. Over time, this normal wear and tear rapidly increases. Once the joint filler fails completely, the edges of the joint begin to chip and spall. If not properly maintained, the damage will become more of an issue.
Floor Surveys and Cost Analysis
FCI will provide a comprehensive floor survey at the customer's request. From this survey, our clients are able to budget accordingly for capital expenditures moving forward
From initial repairs to ongoing maintenance, you can use this survey as a roadmap to returning your floor to a logistical asset.
