Overview

The OX Professional stainless steel groover cuts clean control joints in fresh concrete. The 75 x 180mm blade carries a groove that is 5/8in wide at the top and 5/16in at the bottom, and the depth of the cut is set by the tool you choose: 10mm with the OX-P014210 or 19mm with the OX-P014219. The reversible DURAGRIP handle keeps the tool comfortable as you run the joint line.

Grooves control where a concrete slab cracks. By cutting a weakened line into the surface while the concrete is still workable, you steer the natural shrinkage crack to a straight joint instead of letting it run wherever it wants. The stainless steel blade stays clean and rust free against the wet mix.

What You Need to Complete the Job

Run the groover after the float pass, once the slab will hold a clean line. Screed and float first with an OX Pro magnesium float, and use an 8 inch gauging trowel to tool the edges of the joint. See the Concreting Tools range for the rest of the finishing kit. Cut the joint full depth in one pass and keep the blade square to the slab.

Frequently Asked Questions

What does a concrete groover do?

A groover cuts a control joint into fresh concrete while it is still workable. The groove creates a weakened line that the slab follows when it shrinks as it cures, so cracks stay straight and hidden in the joint instead of running across the surface. It is the standard way to control cracking on paths and slabs.

What groove depth should I use?

The tool carries a 10mm depth (OX-P014210) and a 19mm depth (OX-P014219). A general rule is a joint depth of about a quarter of the slab thickness, so the 10mm tool suits a thinner slab and the 19mm tool suits a heavier pour. Choose the depth to suit the slab you are pouring.

Why is the blade stainless steel?

Stainless steel stays clean and rust free against wet concrete, so the groove face stays sharp and the blade does not drag the mix. It also means the tool does not need drying and oiling the way a carbon steel groover does after a pour.
