Before carrying out any concrete floor remediation work, it is important that the cause of the crack is understood and, if necessary, rectified. Industrial concrete flooring in factories and warehouses will eventually require repairs.Ĭoncrete floor slab surface cracking – causes and repair optionsĬracks in factory and warehouse floors are caused by a number of factors including temperature changes, changes in moisture levels, stress loads (such as heavy traffic or heavy objects), ground or building movement, the hydration process of the concrete slab when it is curing, or poorly placed contraction joints (see later).

These material variations combined with the differences in concrete floor laying methods and the end usage flooring loads, traffic & environment can result in a variety of defects arising in any warehouse floor or industrial floor which require specialist repair - these are described below. The concrete which forms the warehouse floor or factory floor is a composite material which is composed of various constituent materials: a binder, usually cement, aggregates, and water as follows:Įach of these constituent materials can vary in its chemical makeup and performance characteristics, depending on where it was quarried and the manufacturing methods and conditions used to produce it. The concrete floor surface must be maintained in good condition to ensure that the required operational efficiency levels of the building are achieved (otherwise repair will become necessary) The concrete floor slab is arguably the most important element of any factory or warehouse building – it is the platform on which all operations within the building take place.

The topics covered in this article include: The below article helps you to understand range of issues which can arise with the concrete flooring surfaces in warehouses & industrial factory buildings and the range of repair& refurbishment solutions which are available from industrial floor repair contractors. This creates an area that can be used to put the epoxy minimizing the waste.Industrial & Warehouse Floor Repair- An Overview

On narrow cracks apply a bead of caulk on the side of the concrete crack at least 1/8" from the edge of the crack.

Verify before proceeding that the crack is manageable and can be fixed using the crack kit.

When the crack is too wide, the injection method might not work.

Maintain the ports for at least 48 hours to make sure the concrete crack is sealed.

This is only recommended when it is a small leaking area. If there is a leak in the top seal, use a crayon to seal the small leaking area.Watch out for epoxy backflow as that could be a result of debris blocking the epoxy flow or perhaps the crack is not continuous.You can also use a heat gun to remove the epoxy paste. Remove the top seal using a chisel or scraper.When filling wide cracks, wait some time, not a lot, ensuring that the epoxy is filling the concrete crack.Larger cracks require more epoxy injection pressure.Start with a low-pressure injection setting and increase the pressure as needed.
