A bull float is used to smooth 95% of a slab, but it has a tendency either to pull a small amount of concrete away from the edges of the slab or to push concrete toward the edge. A hand float is used to level and smooth these areas so that they match the rest of the slab.
Floor preparation is the process of preparing the existing flooring to receive new flooring and ensure that your new flooring will look great, lay flat, stay bonded and not fail. In many cases, the existing flooring needs to be removed which can lead to a multitude of issues.
A floor grinder is used to produce a smooth finish on flat surfaces for free movement floors. Free movement floors refer to areas where materials handling equipment operate in random, non-defined directions and have an infinite number of travel paths.
Mixing concrete is simply defined as the "complete blending of the materials which are required for the production of a homogeneous concrete". This can vary from hand to machine mixing, with machine mixing being the most common.
Sprayed concrete is the method by which concrete is sprayed into place, rather than the more conventionally used pouring or placing into the formwork. Wet process sprayed concrete: uses batched wet concrete pumped through a hose or pipe to a discharge nozzle where high-pressure air propels the concrete into position.
Grouting in civil engineering refers to the injection of pumpable materials into a soil or rock formation to change its physical characteristics. It is one of the ways groundwater can be controlled during civil engineering works. The purpose of grouting can be either to strengthen a formation or to reduce water flow through it. It is also used to correct faults in concrete and masonry structures.
Concrete coring utilizes a diamond cutting drill to cut a perfect round hole in any concrete structure. The process is low-noise, dust-free and non-percussive, meaning it is the most popular choice when it comes to cutting.
Concrete cutting is a process of controlled sawing, drilling and removing concrete. Skilled operators use special saws to cut concrete and asphalt with precision, accuracy and very few mistakes. A high-standard commercial concrete cutting company should be using these modern concrete coring strategies and tools.
Concrete demolition is the tearing down of concrete buildings and other structures. ... Concrete building demolition not only makes it possible for new communities to be built, but it also removes old and unsafe buildings from properties.
A breaker is a powerful percussion hammer fitted to an excavator for demolishing concrete structures or rocks. It is powered by an auxiliary hydraulic system from the excavator, which is fitted with a foot-operated valve for this purpose.
Construction of new roads, highways, flyovers, re-carpeting of roads or minor road repairs all come under the common header of road construction. Based of the nature of road construction various machines are used in different combinations to get the work done.
Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mould, grime, dust, mud, chewing gum and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces. Machines that produce pressures from 750 to 30,000 psi (5 to 200 MPa) or more are available.
