Basic working techniques
Sawing contraction joint
As concrete hydrates or cures and begins to set, it develops
internal stresses which may cause random cracks.
Random cracks cast doubt on the quality and workmanship of
the concrete. Contraction joints are cut in concrete to relieve
these stresses before they seek their own relief in the form of
random crack.
The Soff-Cut Ultra Early Entry system controls random
cracking through the early timing of a saw cut at
predetermined locations to create weakened planes in the
concrete that subsequently crack at the bottom of the cut to
relieve stress.
Husqvarna sawed contraction joints should be a minimum of
1/8th the concrete depth and a minimum of 25 mm (1") deep.
Contraction joints should be sawn as soon as the concrete
will support the weight of the saw and the operator without
marking or damaging the concrete.
There are many possibilities for joint layout. Joint layout
should be provided, the saw contractor should submit a
detailed joint layout for approval prior to cutting.
