The Stages of Applying Concrete Protection of Effluent Treatment Plant

by with No Comment Flooring SolutionsFlooring systems

We were contracted in December 2020 to provide a solution for the effluent treatment plant at the new Harris bottling plant. The system we recommended involved the following steps.

  1. Surface preparation.
  2. Repair of concrete surface.
  3. Application of first coat of protection.
  4. Application of construction mesh.
  5. Application of last coat of protection.

Stage 1: Surface preparation: This involved grinding to remove surface laitance to expose the good concrete below. This will aid in increasing bonding and exposing unsound concrete.

Stage 2: Surface Filling:

Ā We used of MasterBrace ADH 2200 to fill all depressions and damages on the surface. Some of the advantages of MasterBrace ADH 2200 are its high strength, non-slump, impact-resistant, and good chemical resistance.

Stage 3: Application of first coat:

We applied the first coat of Masterprotect 180 which is a protective high build epoxy resin coating specifically developed to protect concrete. Masterprotect 180 is durable, non-toxic, has high chemical resistance, high-temperature water resistance, and is a waterproofing agent.

Stage 4: Added a construction mesh / Fiber mesh.

The purpose of this was to reduce water loss from the concrete as well as enhance the structural integrity.

Stage 5: Application of second coat:

For the final stage, we once again applied Master protect 180 for a final coat.

Finished Effluent treatment plant with MasterProtect 180 coating.

Why Ucrete Flooring is The Right Choice For Food and Beverage Areas

by with One Comment Flooring SolutionsFlooring systems

Developed more than 30 years ago by BASF (Now Master Builders Construction Chemicals) as the answer to the most demanding industrial environments, Ucrete technology is the original polyurethane flooring solution that provides a powerful layer of protection for both new and existing concrete surfaces. It has a high energy absorption capacity of about twelve times that of a 50 Newton concrete.

It is dense and impervious and used in industries that require the highest level of hygienic standards. Ucrete is accredited for use in pharmaceuticals and food processing facilities mostly because itā€™s anti-microbial, washable, non-toxic, and resistant to a wide range of aggressive chemicals.

Itā€™s also resistant to high temperatures and thermal shock. It can be used over a wide temperature range from -40 Ā°C to 130 Ā°C. And a regular 9mm Ucrete floor can withstand discharges of boiling water.

A cold room floor at Nearest in-flight Services which we upgraded using Ucrete 200D.

In order to achieve the right degree of slip resistance, Ucrete is available in a range of surface profiles from smooth to high textured floors and these are available in matt or gloss.

Ucrete is an ideal flooring solution because it stands out from the rest and thatā€™s we at Svista recommend it to our clients especially those looking for the highest hygienic standards and those in the toughest industrial environments.

This year we at Svista have been privileged to lay Ucrete flooring systems for both HOT INDUSTRIAL KITCHEN (Newrest) and COLD STORAGE WAREHOUSES. (Yokuku).

Ucrete UD 200 at 6mm density for the main floor.

Advantages of Polyurethane Flooring Systems

by with One Comment Flooring systems

What is Polyurethane?

In the industrial world, epoxy and polyurethane are both thermosetting polymers, their differences in function and performance are vast. For concrete floor coating applications, the most durable, longest-lasting coating systems usually include the use of both epoxy and polyurethane. However, it should be noted that each has advantages over the other. For example, Polyurethane is renowned for its extremely durable and flexible synthetic material and some of its advantages include:

  1. Flexibility of polyurethane. While, technically, epoxy is harder and therefore more durable ā€“ weā€™ve found that polyurethane lasts longer because it flexes with an impact and does not abrade as heavily as epoxy.
  2. Resistance to solvents and alkalis. As with epoxy, certain chemical reactions simply have less impact on polyurethane products than epoxy ones. For areas in contact with oils and solvents, polyurethane is the best option.
  3. Speed of curing. Polyurethane will cure faster than epoxy in most situations. In time-sensitive operations or where the resin is needed for a mission-critical application, this is one of the advantages polyurethanes bring.
  4. Resistance to temperature extremes. The flexibility of a polyurethane coat also comes with another benefit ā€“ when the resin goes from hot to cold rapidly (or vice-versa) it tends to flex rather than becoming brittle and breaking. This can be very important for some project-specific areas.
  5. Resistance to scratching. The polyurethane finish is less scratchable than the epoxy finish. This ensures that the floor maintains its aesthetic properties longer than epoxy floors undergoing similar treatments.
  6. Life cycle costs. An important advantage of polyurethane flooring systems is the possibility to renew the topcoat without complete removal of the flooring system ā€“ a process called ā€œretoppingā€. As compared to other flooring systems that have to be replaced when reaching the end of their lifetime. Polyurethane flooring systems are especially advantageous in the case of long-term usages of 40 years. Within this period, most of the comparative flooring systems have to be replaced at least once.

On the other hand, epoxy floors are resistant to a large number of chemicals such as solvents and acids. They are decorative and come in different colors, they are easy to clean and they are robust making suitable for heavy use and mechanical loads, such as forklift traffic in warehouses, workshops and production areas.

However, when it comes to epoxy vs polyurethane flooring systems, the important takeaway is to realize that both product technologies work well in conjunction with each other to produce a durable, long-lasting flooring solution. As part of an international group of licensed applicators, we at Svista are available to advise and recommend the right flooring system to your facility.
