In the modern world of construction, the quality and durability of flooring is one of the most important concerns of employers and project engineers. Tehran, as the capital and industrial hub of the country, always needs new and high-quality solutions for concrete surfaces. Professional execution of butterfly trowel concrete for flooring in Tehran is one of the best and most cost-effective methods for creating smooth, polished, wear-resistant and highly resistant surfaces. This method, which is widely used in industrial, commercial and construction projects, can guarantee the longevity of your floor structure if it is performed by an expert team such as Pasargad Hard Concrete Company. In this article, we will do a detailed and technical review of this process, the advantages and reasons for choosing Pasargad Hard Concrete Company.

What is butterfly trowel concrete and why is it popular in Tehran?

Trowel concrete, which is also known as smooth concrete or hard concrete, is a type of concrete finishing that is done by mechanical devices called Power Trowel. In flooring projects in Tehran, due to the high volume of work traffic in sheds, factories and multi-storey parking lots, there is a need for a surface that is resistant to erosion, impact and the penetration of oil and chemicals.

The butterfly trowel concrete application system creates an integrated and very dense structure by compressing the surface of fresh concrete and integrating hardener powders with the top layer of concrete. This density makes the permeability of concrete to be minimized and the dust caused by concrete wear (which is common in traditional concrete) is completely eliminated. In a city like Tehran, where industrial standards are becoming stricter day by day, using this method is an unavoidable necessity.

The stages of specialized implementation of butterfly trowel concrete by Pasargad Hard Concrete Company

The correct and principled implementation of concrete flooring requires technical knowledge, advanced equipment and skilled labor. Pasargad Hard Concrete Company with years of experience in the field of property trowel concrete in Tehran and its suburbs, performs the floor construction process in several precise steps to achieve the best output.

1. Preparation of the bed and accurate tilting

The first step in flooring is preparing the project bed. This stage includes soil compaction, concrete implementation, and then reinforcement or meshing. Precise adjustment of the level and slope of the substrate is very important, because the trowel moves on fresh concrete and any unevenness in the substructure can lead to cracks or lack of final alignment. The technical team of Pasargad Hard Concrete Company provides the most accurate level for the start of concreting using mapping and laser cameras.

2. Concreting and initial leveling

After preparation, concrete with a certain grade (usually grade 350 or 400) which is suitable for industrial or commercial use, is poured in place. At this stage, it is necessary to use devices such as laser screed or vibrating screed to spread concrete evenly and remove air bubbles. Professional execution of butterfly trowel concrete requires concrete that has a suitable slump (psychology) so that the machine can work on it.

3. Spreading hardening materials (Hardener)

One of the most important steps, which is the main difference between a normal concrete and anti-wear concrete, is the spraying of colored or simple hardening powders on the surface of fresh concrete. These powders, which contain hard mineral and synthetic aggregates, cement and pigment, increase the wear resistance of the surface several times. Pasargad Hard Concrete Company uses the best brands of hardener powder available in the market for flooring projects in Tehran to ensure color durability and surface resistance.

4. Power troweling operation

After the concrete begins to set a little and can bear the weight of the machine and the operator, the troweling operation begins. This step consists of two parts:

Tray trowel (Floating): First, by installing the tray on the blades of the propeller trowel, the concrete surface is pounded and smoothed until the hardening powder is completely combined with the concrete juice.
Finishing trowel: After removing the tray, the polishing operation begins with the main blades of the machine. This work continues until a completely shiny, glassy and dense surface is created. The skill of operators of Pasargad hard concrete company at this stage determines the final quality of the work.

5. Cutting and creating expansion joints

Concrete shrinks after drying, which can lead to irregular cracks. To prevent this, the executive team cuts expansion joints in standard dimensions using cutters. These seams are later filled with polyurethane mastics.

6. Curing and processing

The last step is to protect the concrete against the rapid evaporation of water. The use of curing materials or continuous water spraying makes the concrete reach its maximum strength and does not peel.

Applications of butterfly trowel concrete in industries and commercial centers of Tehran

Tehran, as the economic center of Iran, hosts a wide range of projects, each of which has specific requirements. The services of specialized execution of butterfly trowel concrete for flooring in Tehran, provided by Pasargad concrete company, cover all these areas:

Flooring of industrial sheds and factories

In the industrial towns around Tehran, such as Shamsabad, Nasirabad and Abbasabad, sheds are used by forklifts and heavy machinery. Butterfly trowel concrete is the best option for these environments by creating a dust-free and impact-resistant surface. High compressive strength makes the floor of the shed not to settle or break under heavy loads.

Multi-storey and commercial parking lots

Luxury commercial complexes in Tehran need parking lots that have visual beauty in addition to resistance. Applying colored concrete with a butterfly trowel creates a polished and beautiful surface that is very easy to clean and increases light reflection in the parking lot environment. Also, the screeching sound of car tires is minimized in this type of flooring.

Warehouses and cold stores

Environmental health is the first priority in food and pharmaceutical warehouses and cold storages. Butterfly trowel concrete does not allow the growth of bacteria and fungi due to its uniform surface and without pores, and it is very easy to wash with detergents. Pasargad hard concrete company prevents the accumulation of pollution in the cracks by the precise execution of the seams.

Open spaces and gas stations

Resistance to Tehran's extreme temperature changes (summer heat and winter cold) as well as resistance to oil spills has made hard concrete an ideal option for gas stations and outdoor areas.

Comparison of butterfly trowel concrete with other flooring methods

The question may arise, why should we choose specialized execution of butterfly trowel concrete for flooring in Tehran instead of methods such as epoxy, stone or mosaic?

Compared to epoxy: Butterfly trowel concrete is much cheaper than epoxy and has a higher mechanical resistance against sharp and heavy objects. Also, unlike epoxy, which may become moldy due to the humidity below, concrete breathes hard and does not suffer from separation. Of course, butterfly trowel concrete can also be used as an excellent substrate for epoxy.
Compared to stone and mosaic: The execution speed of butterfly trowel concrete is much higher (several hundred meters per day compared to several tens of meters of masonry). Also, its final cost is much lower and it does not have problems such as loose stones or breaking them under traffic load. The integrity of the troweled concrete surface is more beautiful and efficient than the plastered surfaces.

Factors affecting the price of concrete execution of butterfly trowel in Tehran

The cost of property trowel concrete depends on many factors. Pasargad Hard Concrete Company, with complete transparency in pricing, includes the following items in the cost estimate:

Project size: Usually, in projects with a large size, the unit cost is reduced.
Type of hardening powder: The use of colored powders (red, green, blue, etc.) has a higher cost than gray powder. Also, the brand of powder (Iranian or imported) is effective in the price.
Concrete thickness: The thickness of concreting (usually between 8 and 15 cm) affects the volume of concrete consumed and the final price.
Concrete fibers: Using polymer fibers (PP) or metal fibers to reinforce concrete instead of rebar changes the costs. Pasargad Hard Concrete Company usually recommends the use of fibers to increase tensile strength and reduce cracks.
Location: Access to the project site in Tehran and the possibility of transferring equipment can also be part of the costs.

Despite these factors, flooring with butterfly trowel concrete is still considered one of the most economical methods for large surfaces in Tehran.

Maintenance and cleaning of hard concrete flooring

One of the reasons for the popularity of property trowel concrete for flooring in Tehran is its ease of maintenance. After the completion of the work by Pasargad hard concrete company, the employer can use his flooring for many years by observing a few simple points:

Periodic washing with water and neutral detergents to maintain gloss.
Preventing from spilling strong acids that may react with cement.
Periodic inspection of expansion joints and repair mastics if needed.

The importance of using fibers and additives in Tehran concrete

The climate of Tehran and the environmental conditions of construction projects require that the concrete used has special properties. Pasargad Hard Concrete Company uses additives such as lubricants (to reduce the ratio of water to cement and increase strength) and microsilica gel (for impermeability) in the specialized execution of propeller trowel concrete.

Also, the use of polypropylene fibers or metal fibers in flooring concrete is a very suitable alternative to traditional meshing. These fibers spread throughout the volume of concrete and prevent the creation of hairline cracks that occur due to plastic shrinkage of concrete. This technique increases the execution speed and reduces the cost of buying and installing rebar.

Common mistakes in the implementation of butterfly trowel concrete

Many unprofessional contractors in Tehran cause damage to the employer by making mistakes. Recognizing these mistakes shows the value of Pasargad concrete company's work:

Early or late troweling: If troweling is done early, the surface of the concrete will be wavy, and if it is done late, the final finish will not be polished and there is a possibility of burning the concrete.
Insufficient use of hardener: Using less hardener powder to reduce costs will cause the top layer to wear quickly and the underlying concrete will be visible.
Adding water to the surface: Some people add water to the surface to make troweling easier, which greatly reduces the wear resistance and pulverization of the surface in the future.

Pasargad Hard Concrete Company, with the strict supervision of its engineers, prevents all these mistakes and delivers a perfect project.
