Since it is of the same quality as the main concrete, it has excellent adhesion strength.
The high-strength mortar compact spacer, JL Spacer, has excellent adhesion because it is made of the same material as the main concrete. With a compressive strength of over 70 N/mm², it is ideal for prestressed concrete. Its superior strength and hardness eliminate the need for using two pieces, thereby reducing costs. It does not deform even in high temperatures or sub-zero climates, preventing surface cracking of the concrete. The contact points with the formwork are point contacts, 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 "technology knows no borders," we quickly adopt 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 technical partnership with the British company Cretec and launched high-strength mortar spacers. Furthermore, in 1986, we signed a contract 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 broadly to the world, not only within Japan, from the manufacturing of construction materials, machine parts, shipbuilding components, and multi-story parking components, to surface treatments such as dacromet processing and zinc plating.
