All you need to know how concrete repair contractors patch concrete. The architectural work is highly based on concrete usage. Opposite to popular belief, concrete is different from cement. It is a mixture of water, gravel (sand, rock) and cement. This mixture then becomes dry and takes the shape which we require for the construction work. This is the mixture we are all familiar with. Concrete is highly durable and can last up to 20-30 years, but there is a complication. With time the concrete starts to crack up, and there may appear some holes in it. These nasty cracks can become a real eyesore. To get rid of these unwanted cracks, first, you must know the types of concrete cracks.
There are two types of cracks
● Wire Crack
● Hairline crack
The hairline crack is a bit smaller and can be filled up with masonry crack filler after cleaning the debris from the damaged area. The wire crack is a bit tricky and can be repaired using a patching mix of good quality. The wire cracks can take a little bit of your effort because they are deep, and the surface can move. First, you need to clean up the area and gradually add the mixture and smooth it.

● Stencilled Effect
Stencilling produces an image or pattern by applying pigment to a surface. Adhesive-backed masking patterns made of vinyl or plastic create a stencilled effect. The adhesive keeps the pattern in place while the decorative treatment of choice is applied to it. This creates a lovely design.
● Air Entrainment
Air entrainment or free-surface aeration is the process that traps the un-dissolved air bubbles and air pockets that are made during the flow of liquid. Adding an air entrainment admixture to fresh concrete can trap the microscopic air bubbles and improve the hardened concrete's durability and resistance.
This process is used to give an antique look to the concrete. This technique involves the use of color layering.
Seeding is an ancient technique, but it is still relevant today. In seeding, the builders use different kinds of rocks and scatter them all over the concrete's surface to give a colorful effect.
● Bonding Agents
Bonding agents are often used in repairing processes and increase the adherence of coatings and toppings to the existing surface. It is also used to bond new concrete to the old and is also known as the prier.
● Crack stitching
It is used for repairing cracks with the help of drilling holes on both sides of the crack and then grouting in wires or u-shaped metal strips that span the crack.
● Crack Chasing
It is also used in crack filling. The cracks are routed out with a saw or angle grinder before filling up with the repair material.
To provide extra protection from water damage, a penetrating liquid chemical is used. This chemical is used to harden and solidify the surface. This process is often used for polished concrete.
● High Build Coating
This is a protective and decorative coating that creates a thick film on the surface and provides protection.
Before applying any repairing material on the damaged surface, one must use these masking tapes, adhesives, and stencils. This will limit the repair to the damaged area.
● Polymer modified overlay
Overlay manufacturers use different kinds of polymer resins and often blend them to create proprietary products with unique characteristics. It improves performance, wears resistance, and aesthetic quality.
