Grinding and Leveling Control Joints

All control joints need the right joint filler to have the chance to hold up to the severe stresses from the weight transfer from one floor slab to the next. This type of stress at the control joint, will cause joint failure from the vertical movement over time. Hard tire forklifts will chip, crack, and damage both sides of the joint, causing down time to repair hard forklift wheels. The repair method used by Concrete Repairman starts with floor grinding. Grinding the concrete slab joint enables the best transfer of weight smoothly across the joint. Grinding and leveling floor joints also properly profiles the surface of the concrete slabs to allow for best adhesion for joint filler products at the same time.

Epoxy Control Joint Filler Preparation Method

All concrete surfaces are profiled to the correct profile for best adhesion and molecular attachment to the vertical sides and top of control joints. The best repair method is; Grinding both sides of the control joint using vertical cutting diamond blades penetrating to a depth of equal value as the width of the joint. Usually 3/4 width cut, and 1″ depth is used to open this type of joint open. Joint Filler Epoxy is also supported by using silica sand, to fill voids in the vertical break of the slab below where the epoxy is filled. Without this support, the control joint filler will fail from the vertical weight of the hard tired forklifts rolling across it.

Grind and Level Control Joint Fill After Install of Epoxy

After the install of the control joint filler or epoxy joint fill, the access is then ground to the same elevation as the adjacent floor slabs. This type of repair method is then considered complete. The discoloration of the concrete from grinding, overtime will blend in with the existing floor slabs. The most important consideration with this type of industrial warehouse floor joint repair is; The joint filler, or epoxy joint fill has to be flexible enough and at the same time, be able to hold up the vertical pressures being applied. Most all concrete repair contractors do not understand this type of repair because they don’t understand all of the necessary steps to make the best repair possible.

Heaved Concrete Floor Cracks and Construction Joints

Concrete heaved joints become loose mainly because they lack an effective load transfer device such as dowels, tie bars, or reinforcing steel. Other factors include excessive curling or warping, high drying shrinkage, and wide temperature swings. The size and cost of floor joint repairs can be kept to a minimum if the damage is detected and repaired at an early stage. Regular inspections should be made to check that the existing joint sealant is doing its job to protect and maintain the floor joint. Once the damage has been allowed to progress beyond the scope of re-sealing the joint, it will be necessary to reconstruct the joint. Our heavy duty repair mortar is specifically intended for use on industrial floor to repair floor joint damage quickly and with minimum disruption to the ongoing operations. Wide joints increase the risk of spalling due to the deflection of the joint sealant under load. It is therefore important to reduce the width of the joint opening at surface level. Our tried and tested floor joint repair solution allows a wide ‘traditional expansion joint’ to be replaced with a neat wide, fully sealed saw cut. Each of our floor joint repairs are ground smooth and flush with the adjacent floor surface to ensure that wheeled traffic has a smooth transition over the repaired joint. Most warehouse and industrial floors will have joints with spalled edges and this should be seen as an early indication of more serious potential long term damage. The floor joint edges are vulnerable to damage and tend to ‘spall’ under the impact from hard wheeled traffic. Our floor joint sealant is rigid enough to provide support and protection to the concrete floor, but also flexible enough to accommodate any opening of the joint and still remain bonded to at least one face of the concrete slabs. Concrete Repairman’s 2 part epoxy joint fill is a 100% solids semi-rigid epoxy joint filler used to protect saw cut joints in concrete slabs or in repair of existing damaged joints. This epoxy absorbs the impact and shock of heavy loads and steel wheeled traffic, preventing erosion of control joint edges. Our epoxy joint filler is available in Regular Cure (RC) 24-48 hours cure @ 75ºF, Fast Cure (FC) 12-24 hours @ 75ºF, and Super Fast Cure (SFC) 10-20 hours @ 75ºF, formulations. Concrete Repairman LLC. provides services and consultations on material selection, specification, troubleshooting, and other information on the proper repair and protection of concrete surfaces. Concrete Repairman LLC. is available to assist you in any floor problems. Warehouse Floor Joint Repair weight transfer across a construction joint on warehouse floors can damage the slabs on both sides. As the weight of forklift moves across the joint, one slab section is lower than the next slab that is about to carry the load, causing the hard tire wheel to chip the side of the joint. Over time this damage grows and begins to cause even more damage to occur faster. For forklift operators, I is a very bumpy ride, and cause accidental products to shift off the pallets the forks are carrying. Call The Concrete Repairman at 602-418-2970
