Groutec L

Groutec L

Half-grouted system with larger cavity

Groutec L is a mechanical splicing designed for the connection of precast elements.

Each Groutec L sleeve features a threaded end for the connection to reinforcement bars at the precast factory and a wide body allowing for more misalignment tolerance for the connection of two precast elements at site.

Groutec L is designed and manufactured in compliance with Eurocode 2, BS8110, ISO 15835, ACI 318 type 2, and AASHTO code requirements
