Why do you need a keyway in the construction of a wall?
typically, a keyway is found in a wall made of concrete where there is two separate pours which abut themselves, otherwise referred to as a cold joint. it makes sense to insert a concave keyway continously along the length and in the center of a section of the first wall section poured to receive an abutting concrete pour at a later date. this inserted keyway creates an interlocking style effect between the two abutting pours which creates a higher quality connection than simply butting the two pours with nothing to interconnect them. typically, a keyway is found in a wall made of concrete where there is two separate pours which abut themselves, otherwise referred to as a cold joint. it makes sense to insert a concave keyway continously along the length and in the center of a section of the first wall section poured to receive an abutting concrete pour at a later date. this inserted keyway creates an interlocking style effect between the two abutting pours which creates a higher quality connection than simply butting the two pours with nothing to interconnect them.
