Delamition
​
Delamination in concrete slabs can be a serious problem, but often they are "heard" before they are seen. Here's an example. A concrete floor slab placed days ago has hardened and cured. As work from other trades continues in the area, someone drops something metal onto the slab and an unexpected sound is heard or the top of the concrete starts to break down. Instead of the clear ringing sound you would expect when metal hits solid concrete, a dummy sound or loud clack draws your attention. Using a chain to drag around this spot, you identify more hollow-sounding areas. What's been discovered is a surface delamination in the concrete floor.
How does delamination happen?
When fresh concrete is placed and compacted, the solids (cement and aggregate) settle. This natural settlement causes excess mix water and entrapped air to be displaced (called bleeding), and the lighter materials migrate toward the surface. If finishing operations start prematurely and close or seal the surface before bleeding is completed, air and/or water are trapped under the densified surface mortar. As concrete hardens, subsurface voids develop where the water or air is trapped. These voids create weakened zones right below the surface that can eventually detach during slab use. Very thin mortar layers over delamination may even detach when struck with a hammer, as you try to sound out the extent of the delaminated area.
Cracks
​
Why Cracks Form In Concrete Structures
Concrete provides structures with strength, rigidity, and resilience from deformation. These characteristics, however, result in concrete structures lacking the flexibility to move in response to environmental or volume changes. Cracking is usually the first sign of distress in concrete. It is, however, possible for deterioration to exist before cracks appear. Cracking can occur in both hardened and fresh, or plastic, concrete as a result of volume changes and repeated loading.
This involves tensile stresses being loaded onto the concrete, the cracks occurring when the force exceeds its maximum tensile strength. We at Bluey Technologies maintain that it is important to understand the reasons why cracking occurs, the type of crack formed, and cracks’ effects on structural stability. Once you understand these points you can take the appropriate action. This may mean leaving the crack alone, injecting the crack with an appropriate material, or applying other suitable repair methods.
Latexing
Before fitting any flooring, it is essential that floor preparation is done properly.
Taking the time to get this right now will ensure a perfect finish – with no bumps, ridges or other problems arising. Not only that, the better quality the sub floor, the longer your flooring will last.
As part of the floor preparation, our team check the moisture levels of any subfloor. If the moisture is above 75% relative humidity (RH), it is imperative that the floor either be left to dry out, or a damp proof membrane installed.
The first step in floor preparation is to clean the floor, making sure that all dust and dirt is removed.
We are the experts when it comes to floor preparation,
priming and latexing. The exact requirements and methods
used to prepare, prime and latex your floor will depend on the environment, type of
floor to be fitted and the usage. We have worked on commercial flooring in every industry, including leisure, retail and
commerce. Whatever the job, we will advise on priming and latexing to maximise the longevity of your flooring.

Joint Sealing
A sealer is soft and able to accommodate the concrete slab's expansion and contraction. The sealer's purpose is to prevent water, ice, and dirt from getting into the joint (and into the subgrade) and to prevent intrusion from below the slab—including of radon. Sealers can also improve the appearance of floors and slabs.A filler is a rigid material that supports the edge of the joint when heavy traffic crosses. This type of material is only effective with saw-cut joints; rounded tooled edges can't support the filler.Both sealers and fillers should only be installed after the slab has had a chance to shrink as much as possible. Fillers are only effective if installed after the concrete has gone through most of its shrinkage, although that can take a year or more. Fillers and sealers should be checked at the end of the first year of service and repaired or replaced as needed.Effective sealant materials must bond to the concrete, be impermeable, and be able to handle the expansion and contraction.Before installing a sealant, the joint must be dry and free of dust and debris. Vacuum it thoroughly before sealing. Carefully follow the sealant manufacturer's installation instructions.

Lignite
Lignite in concrete.
Lignite is a soft, weak, black or brown substance, akin to coal, naturally occurring in some aggregate sources. For most concrete applications, e.g. foundations, mass concrete, concrete covered by finishes, the effect of lignite is relatively insignificant. The main problems relate to exposed power-trowelled slabs and architectural finishes.
The particles are less dense than those of the aggregate, rising to the top surface during placing and compaction. The finishing process may cover the lignite particles with a layer of mortar. As the concrete dries and is worn, the mortar skin break down, leaving unsightly black marks and holes in the slab surface. There may be only a few particles per square metre, but in extreme cases there may be tens or hundreds of small specks. While they do not have structural implications, the particles may be detrimental to surface performance in terms of appearance, wear, abrasion, cleanliness, and compatibility with finishes.
