Repair of cracks in concrete floors in a warehouse, in production, in a parking lot is one of the most requested requests from owners of commercial real estate.

Why is it important to repair cracks in concrete industrial floors?

• One of the problems associated with cracks in concrete floors is the formation of cement dust that comes out of the cracks when the floor is heavily used by forklifts, machinery, personnel, etc.

• The presence of cracks in concrete floors leads to an increase in the cost of maintaining, maintaining and caring for an industrial floor.

What happens if the cracks in the concrete floors in the warehouse are not repaired?

• Stopping the operation of the warehouse for an indefinite period, in the event of the formation of cement dust, in the event of cracks in the concrete.

• Threat to life and health of the company's employees, due to the formation of cement dust, which has to be breathed.

• If you ignore the cracks in the concrete, do not carry out local repairs, subsequently, the industrial concrete floor can drastically succumb to wear, which will lead to a major overhaul.

• Depreciation of the undercarriage of loading and unloading equipment, when operating the floor on large cracks (the floor can sag and create an obstacle when moving).

• The value of the property decreases.

Cracks in concrete floors in a warehouse

An important point when deciding to repair, how and with what, to repair a crack? It is necessary to understand the cause of the occurrence and formation of cracks in the concrete floor.

Why cracks form in concrete floors, read in our article "Cracks in concrete, what to do?"

Consider the standard types of repair of cracks in a concrete floor in a warehouse.

There are several types of cracks in concrete floors

• static cracks.

• Shrinkage cracks.

• Dynamic or active cracks.                    

• Settling cracks, etc.

For an effective choice of repair technology, it is necessary to determine the type of crack, is it active or not active?

Inactive cracks: static, shrinkage, settling (if the shrinkage process is over), repair with rigid or semi-rigid repair compounds, polymer resins, hybrid mixtures.

Types of repair compounds for concrete floors

• Cement repair mortar.

• Epoxy repair compound.

• Silicate repair compound.

• MMA repair compound.

• Urethane resin combined with sand.

• Polyurethane-cement repair compound.

• Epoxy resin combined with sand, etc.

 

Repair of cracks in industrial floors

The main purpose of these materials is to glue the crack and fill the void with a strong composition, which was formed due to crack jointing and cracking.

Example 1

Through crack in concrete

• The crack is embroidered with the help of a grinder, a puncher, a joint cutter or a wall chaser, to the full depth, at a right angle. Ingoda, make a V-shaped cut in the crack.

• Dust removal is carried out.

• Priming the strobe with certain primers, as needed.

• Crack filling with flowable liquid resin, hard resin, hard cement repairer or poured cement repair mortar.

• Also, to eliminate further cracking, the crack is further strengthened using metal anchors made of steel reinforcement, steel wire or other types of fastening. Reinforcement is laid in perpendicular strobes relative to the crack and caulked with a repair compound.

Shrinkage cracks

• Small shrinkage cracks are very difficult to eliminate. As a rule, they do not dust, but visually spoil the appearance of the floor.

• It is possible to eliminate small cracks up to 1 mm using grinding and polishing equipment, and polymer resins.

• It will require polishing the concrete floor in several stages.

• Application of polymer resin to fill microcracks and subsequent machining.

• What will be the result is a lottery, but in any case it will be better than it was.

Non-through crack in concrete floors

• The easiest option for the customer, you can make repairs and start up traffic in two hours.

• The crack is embroidered to a shallow depth and filled with a repair compound or a special sealant, followed by grinding for uniformity of the industrial floor plane.

For example, MasterInject 1315 is a low viscosity epoxy crack injection system.

Ideal for sealing static cracks larger than 100 µm.

It is deeply penetrating and cures to form a permanent and tough seal against the ingress of aggressive liquids and is capable of restoring the structural integrity of concrete elements.

The preferred system is for repairing and sealing "static" concrete cracks.

Injection resin can be used to fill and bond dormant cracks in columns, bridge decks, floors, piers, piers, tunnels, basements, beams and underpasses.

Dynamic or active cracks

These cracks continue to grow, in all directions. It is important to eliminate the cause of the formation of "live cracks", and then proceed with the repair.

When repairing cracks in concrete that are subject to dynamic or thermal loads, elastic sealants, primers, ppe bundles, and an aluminum overlay profile are used.

It is important that the material can be elastic and work together with the crack in expansion and contraction, but at the same time seal the crack from leaching of cement dust and be waterproof.

 

Repair of a dynamic crack in a warehouse

Example 1

Repair of non-through dynamic crack

• Jointing a crack in a concrete floor, U-shaped type of jointing.

• Dusting and priming.

• Installation of a harness, to control the thickness of the sealant.

• Sealing the seam with a sealant (polyurethane, hybrid, polyuria, road bituminous).

Example 2

Through dynamic cracks

Deep or through cracks in concrete floors can be sealed, like expansion joints, with sealants, as well as built-in or overlay profiles.

To prevent cracking, effective, sinus-shaped profiles are used at the stage of installing industrial floors or during repairs.

These armored connections (correctly referred to as "on-site splice systems") offer four important advantages:

• they act as a permanent formwork, creating a secure boundary or visible joint during concrete pouring;

• the profile allows the concrete slab to compress in a controlled manner to prevent accidental cracking.

• profiles protect building connections from impact damage after the building is in use, saving repair costs.

• they provide efficient load transfer between concrete slabs, for a stable and durable floor.
