Wide concrete slabs are made of thick fluid. After it dries on the floor, it becomes hard.
Even the best installation of a large area usually cannot be 100 % perfect, and here there you could see a few hairline cracking, but also random cracks usually happen throughout the lifespan in the slab because of earth movement, weather changes, human traffic, pressure, inadequate humidity level, natural disasters like storms and earthquakes.
These cracks look ugly and property with cracks in the flooring loses its value on the market. Therefore, any concrete slab must have control joints. These joints prevent cracks to expand all over the floor. So, if you are worried about the beauty and safety of the concrete slabs in a building, check your options with a professional building repair and construction company. Albatross Restoration offers top-notch services of placing control joints both in new grounds structures and old concrete slabs. How to Place Control Joints
Two basic strategies are so far the best techniques for placing the control joints.
You need steel reinforcement in this method which controls concrete cracking. Random cracks do not expand or increase when steel reinforcement holds random cracks tightly. The tight grip of the steel discourages the expansion of cracks so they remain small. The combined particles of the concrete on the surface interlock. Thus they keep providing load transfer across the crack. But, it is important to note that applying steel reinforcement increases the possibility of the occurrence of fine hairline cracks in the surface of the concrete slab.
Placing control joints in concrete is another method to control the cracking of the slab. These joints are placed on the surface of the concrete at locations where concrete is expected to crack in straight lines. Placing control joints is an aesthetically appealing process. The cracks happen below the surface of the concrete. The normal behavior of concrete is to have cracks below the surface. However, random cracks on the surface do not happen. So, the appearance of the concrete remains free of cracks. Are Control Joints and Expansions Joints the Same?
No, control joints and expansion joints are not the same. Expansion joints
allow for movement while control joints prevent cracking and expansion of cracks. Two different concrete pours require expansion joints in between. Bigger structures like public buildings and commercial centers mostly need expansion joints. They need filling especially when the concrete floor is going to be polished and coated. Control Joints are a Necessity of Buildings
Not only do outdoor concrete slabs need control joints to buy also indoor wide areas on concrete slabs need them. For the integrity and firmness of the ground, you need to pay attention to placing proper control joints in the concrete slab.
