Concrete tiles made with extremely durable birch plywood

When making concrete tiles, the strength of the paving board is crucial to prevent twisting. FC Beton’s newest production line produces concrete tiles with a speed of 300 paving boards per hour – 1 grouting every 12 seconds! Koskisen’s KoskiForm heavy-duty performance boards are used in the process to keep up the high-quality and smooth production.  

KoskiForm Paving boards are being used repeatedly in concrete tile production at FC Beton in Denmark. There are about 4000 KoskiForm boards totally in this new 5^th production line. For one of older production lines, was bought the first set of 1700 boards 15 years ago – and they are still going strong in the production!  According to FC Beton’s Administrative Director Jens Erik Mølgaard, Koskisen’s paving boards are used because of their durability, strength and consistent quality.

Durable paving boards do not twist in concrete tile production

“The KoskiForm Paving boards are very uniformed. The coating is highly durable and lasts for a long time. The strength of the board is important in concrete tile production to prevent twisting”. Mølgaard states.

“For FC Beton, it is also very important that paving boards’ coating prevents absorption of moisture into the plywood. The key is that KoskiForm boards are delivered with chamfer coating on both sides. We use these paving boards over and over again. In between every set the board is turned to keep the shape. “

Mølgaard emphasizes the importance of uniform quality of KoskiForm Paving boards: “It is very easy to add a new board into the production amongst old ones and it does not cause any problems.”

Chamfer coating prevents absorption of moisture 

In the concrete tile production process, a Koskiform paving board enters the machine and a metal mold is placed on top of the board followed by concrete poured into the mold. Once the concrete is within the mold the machine applies pressure and rattles the mold so that the concrete tile gets the correct shape. It all just takes 12 seconds – and then it is continuously repeated.

The KoskiForm Paving board then transports the grouting to the hardening station where it stays for minimum 16 hours. After this, the boards and molds are transferred back and stacked upon pallets to harden for another 7 days before the tiles are ready to be sent out to the customers. 

KoskiForm Paving boards boost FC Beton’s concrete tile production after several pilots

Before KoskiForm, FC Beton had tried various paving boards on concrete tile production. The durability of birch plywood with different phenolic coatings and thicknesses was not sufficient enough.  Planks made from different woods attached to each other did not last long due to the moisture from the concrete. Plywood coated with fiberglass caused delamination in the plywood due to the heat the concrete tiles transpire when it hardens. Plastic boards twisted due the weight and heat from the concrete tiles. 

The key strengths of KoskiForm Paving boards in concrete tile production 

• The coating is very durable and lasts for a very long time.
• The strength of the board is important and prevents twisting, which causes tiles to break.
• The coating prevents absorption of moisture into the plywood.
• The KoskiForm boards are delivered with a chamfer on both sides.  The chamfer protects the edges of the boards from getting damaged in the production.
• It is very easy to add a new board into the production amongst old ones even after 15 years. 

Fun facts on FC Beton using KoskiForm Paving boards in concrete tile production

• 1^st set purchased 15 years ago (1700 boards) is still going strong in the production
• 2^nd set purchased 13 years ago (1700 boards) still going strong, but since used in leca block production, they are more worn down.
• 3^rd and 4^th set (1700 boards each) still going strong
• 5^th set (4000 boards) used at the new Gadbjerg production facility.
  

FC Beton is a family company founded in Denmark in 1942 by Jens Mølgaard and his wife Sara. Today, it is run by their son Jens Erik Mølgaard along with his son Jens Mølgaard.
