Hi,
What would be the best way to cut slots every 2 inches at a depth of 10mm (with a 3mm width blade)? can be seen it the attachments. It also needs to be square and a very accurate 2 inches between slots.
Otherwise, are there companies out there that can do this task for a reasonable price?.
Cheers

You could probably hire a brick saw with a diamond blade and do it your self.
I'd use a circular saw (or better still the Makita 9" wet saw) running against a clamped on guide for the first cuts. Then a rip guide with a bit of 3mm steel welded on to ride on the previous groove. I'd probably measure and snap some lines with oxide to check that it was all staying in spec.

Another option - make a template out of ply, mdf or whatever, to whatever length you can work with, mark out and cut the slots accurately, and place the template on the concrete. Then using an angle grinder (100 or 125mm) with a diamond blade place into the template slots and cut into the concrete. To get the desired depth into the concrete make the template from an appropriate thicknessed material.
Recently I've had cause to cut concrete using a 125mm angle grinder / diamond blade. It goes like a hot knife through butter and very accurate, course this is subject to operator skill.
Ask a hire company etc how far apart you can set the blades on a wall chasing saw. If they go to 10mm then you know you will have a parallel Ist cut, then by setting a guide against one of these you should be able to progress through the cuts keeping them straight.
Thanx colleagues for all your replies. I was able to borrow a brick cutting saw which made the task so much easier:wink:.
