joint de dilatation

OBS: Le terme français est un spécifique par rapport à l'anglais : le joint de dilatation s'oppose à l'action des variations thermiques alors que le «control joint» s'oppose aux mouvements et déformations des maçonneries en général.

CONT: Control joints can be formed by attaching a strip of wood, plastic, or metal to the form, for vertical surfaces ... or by pressing the strip into the fresh concrete on a slab.
CONT: Use of control joints faced with calking compound has also been recommended to control shrinkage cracking; however, this practice is marked by frequent failures to keep the joints sealed against leakage of rain. Steel joint reinforcement strengthens a concrete masonry wall, whereas control joint weaken it, and the calking in the joints requires considerable maintenance.
