What is a V-groove

Definition of V-groove in Construction

The term V-groove is used on construction and building sites to identify a form of joint, notch or operation that results in a cross-section profile that resembles a V. V-grooves are usually used to allow the proper installation of a joint compound or a joint filler. The V-groove profile allows the material to withstand the fracturing and spalling out of the joint filler if the groove was not V shaped. Due to the dimensional result of the bottom of the groove being narrower than the top, the ability of the product to remain in this type of groove is increased. Whenever concrete or other masonry is being patched or stabilized due to excessive cracking or failures, normally the structural engineer will require that a V-groove be cut into the crack by the use of a mechanical piece of grinding or cutting equipment. This cutting of a V-groove into the crack will allow the proper filling of the crack with joint filler. The intent of the V-groove profile is to allow the joint filler to withstand the movement of the crack and remain intact within the joint.
