Abstract

Referring to figure 1, an embodiment of the invention involves means 1 for controlling cracking in a body of cementitious material, for example concrete, having an elongate base 2, elongate side wall portions 3 and 4 extending from the base and angling towards one another, and an aperture of apertures in the side wall portions. When the means for controlling cracking is in use it can be positioned base down so that a cementitious substance prone to cracking can be poured around and at least partially through it such that cracks which form in the cementitious substance occur at or in the vicinity of the means for controlling cracking.
