Tested reliability

• Joint strength is the same as of solid reinforcement bar
• The joint does not loose its strength even when it is exposed to mechanical seismic and other natural effects
• The strength of the joint does not depend neither on the quality of concrete during construction nor on its state during use.

Economical effectiveness

• No specific qualification its necessary – lower costs for labour force;
• The construction duration is shortened – lower costs and higher effectiveness

Benefits white projecting

• The closeness of renforcement is reduced, the bulk density of concrete is increased.
• Overlapping joints are avoided in areas of maximum tension.
• More possibilities are ensured white making projecting decisions.
