TONGUE AND GROOVE

The tongue and groove assembly technique is commonly used for wood or laminate flooring. This method creates a strong joint between two pieces of wood, without the need for fasteners such as nails or screws. One piece of wood has a thin, elongated piece (tongue) that fits into a groove in the second piece. This joint is resilient and can withstand the natural expansion and contraction of wood during changing temperatures. Despite its strength, modern carpenters tend to avoid the tongue and groove joint because of its time-consuming nature. However, this technique is still popularly used in the construction of hardwood floors, wood panel walls, doors and table tops.
