Since it is of the same quality as the main concrete, it has excellent adhesion.
High-strength mortar compact spacers, JL spacers, have excellent adhesion because they are made of the same material as the concrete body. With a compressive strength of over 70 N/mm², they are ideal for prestressed concrete. Their superior strength and hardness eliminate the need for using two pieces, thus reducing costs. They do not deform in high temperatures or sub-zero climates, preventing surface cracking in the concrete. The contact surface with the formwork is a point contact, resulting in a clean finish on the concrete surface. For more details, please contact us or refer to the catalog.

Company information
In today's world, where it is said that "there are no borders in technology," we swiftly incorporate excellent innovations from around the globe and continuously send our own technologies out into the world. This is JL's principle. In 1984, we formed a technological partnership with the British company Cretec and launched high-strength mortar spacers. Furthermore, in 1986, we contracted with the German company Frimeda for lifting anchors, in 1994 with the German company Halfen for cast-in channels, and with the Dutch company Deha for bar couplers, and we are actively selling these products. As overseas cooperative factories, we have foundries and fine ceramic products in South Korea, two joint ventures and one cooperative company in China, two wholly-owned companies in China, one wholly-owned company in South Korea, and a cooperative factory in Vietnam. We contribute widely to the world, not only within Japan, in the manufacturing of construction materials, machine parts, shipbuilding components, and multi-story parking components, as well as surface treatments such as dacromet processing and zinc plating.
