Are you tired of dealing with recurring frustrations caused by failed concrete slab repairs? Unfortunately, warehouse and plant managers often face the dilemma of work that doesn’t stand the test of time.
Understanding the reasons behind these failures allows you to put an end to them once and for all. For further information on industrial concrete slab repair, you can explore more here.
Common Reasons for Concrete Slab Repair Failures
There are several mistakes and errors that get made again and again in concrete slab repair. Learning about them before hiring a contractor for work will prepare you to make the best choice and select the best team for the job.
Not Addressing Underlying Problems
Before proceeding with a concrete slab repair, conducting a thorough inspection is crucial to identify any underlying problems. Patching over cracking, spalling, or unevenness without assessing the slab’s structural integrity often means the issue will rearise quickly.
Long-lasting repairs deal with the underlying problems to strengthen the slab. Otherwise, it’s like putting a bandage on a broken leg; it might look fixed but will worsen later.
Additionally, it’s critical to check for moisture issues, such as excessive vapour emissions or water infiltration, as these can compromise the longevity of the repair and require additional remediation measures. In other words, never hire someone who comes to make a repair without checking for underlying problems.
Inadequate Preparation
Neglecting concrete cleaning, not creating deep square edges for bonding, and failing to address weakened substrates are the primary culprits behind quick failures of concrete slab repairs. The first step involves thorough cleaning to ensure a clean, bare slate.
Additionally, creating deep edges allows the repair material to securely bond with the slab. In cases where the concrete is weak and easily crumbles, reinforcing it with a deep-penetrating primer becomes crucial.
This primer provides a strong foundation for the repair material. Remember, the quality of a repair is only as good as the substrate it is applied on, so if the concrete is significantly weak, a deeper patch may be necessary.
Incorrect Materials
The materials selected for concrete slab repair greatly impact your repair’s longevity. There’s a range of products available, differing in price and quality.
Often, epoxies are used to fill cracks and divots, but the wrong product can lead to failures within days or weeks. Additionally, the repair’s size should be considered, as the exothermic reaction of epoxy can affect its integrity.
Working times and curing properties also play a crucial role in the effectiveness of these products. Opting for high-quality materials, preferably stronger than concrete, is critical to a successful repair.
Uneven Surfaces
Creating a seamless transition during concrete slab repairs is of utmost importance. Any dips or humps in the repair cause points of impact for wheeled traffic, leading to gradual deterioration and eventual patch failure.
The first step to prevent this is to overfill the patch, then grind it smooth and flush with the concrete surface. This not only ensures a strong bond with the slab but also eliminates potential points of impact that could cause damage.
