VULTURE Posted October 2, 2015 Report Share Posted October 2, 2015 Hi. My manshed stands on some paving slabs and due to a cockup the shed was about six inches smaller than the paved area I laid and due to health and life problems was never sorted at the time,now I need to trim these slabs before any rot starts. What's the best way to trim these reasonably neatly in situ as moving the shed is not an option. Cheers. Vulture Quote Link to comment Share on other sites More sharing options...

harpoonlouis Posted October 2, 2015 Report Share Posted October 2, 2015 +1 above, if you can create a bit of a gap beneath the over hang you can probably cut a slot part way through the slab and just give them a tap and snap them off, save you at least 50% of the cutting Quote Link to comment Share on other sites More sharing options...
kent Posted October 2, 2015 Report Share Posted October 2, 2015 Depends if you want a clean cut or a rustic edge disc cutter or 9 " grinder for former. Scribe and chisel the latter Quote Link to comment Share on other sites More sharing options...

Scribe and chisel the latter This is easier too do if the slabs can be lifted so can be chiselled / worked all the way around. Quote Link to comment Share on other sites More sharing options...
Sha Bu Le Posted October 2, 2015 Report Share Posted October 2, 2015 I'm probably missing something but.......given the shed is sitting on the paved area with an overlap of the pavers, it will still be sitting on the paved area after you have trimmed the slabs so what will you achieve by cutting the paver excess Like I said I am probably missing something, not my forte Quote Link to comment Share on other sites More sharing options...
VULTURE Posted October 2, 2015 Author Report Share Posted October 2, 2015 The paved area is about 4 inches bigger than the shed,when it rains it flows under the shed and will rot the bearers,I want to trim the slabs so they are under the edge of the sides but flush with the bearers. There are not other slabs and the paved area is about 3 inches higher than the surrounding ground. Vulture Quote Link to comment Share on other sites More sharing options...
Dougy Posted October 2, 2015 Report Share Posted October 2, 2015 keep dust down by using a slow trickle from a hose pipe if using a petrol disk cutter, it will also help you to see the straight edge. And dont forget to wear eye protection Quote Link to comment Share on other sites More sharing options...

And dont forget to wear eye protection use a hose lock connection on your hose and attach hose directly on to the stihl saw Flynny Quote Link to comment Share on other sites More sharing options...

clanchief Posted October 2, 2015 Report Share Posted October 2, 2015 Leave them as they are, the water will run off the bearers and off the slabs, when we sold sheds we always wanted the area slightly larger. Chiefy Quote Link to comment Share on other sites More sharing options...
Rst1990 Posted October 2, 2015 Report Share Posted October 2, 2015 I have the stihl ts420 petrol cutter and believe me you won't get any where near the edge with one of these as they are a big unit, unless you tilt the saw which I don't recommend as that's how you loose a leg. Get yourself a mains 9" grinder with diamond blade, you can then cut it really tight against the shed so you will have minimal over hang. Hope this helps Quote Link to comment Share on other sites More sharing options...
jasons gold Posted October 2, 2015 Report Share Posted October 2, 2015 cant you dig underneath the slabs and take them out cut them then put them back once cut Quote Link to comment Share on other sites More sharing options...
humperdingle Posted October 2, 2015 Report Share Posted October 2, 2015 . Spouting and down pipe to divert water.Probably what i'd do. Unless you have an industrial cutter with diamond blade, you'll probably end up cracking slabs, causing different issues. Quote Link to comment Share on other sites More sharing options...

I never noticed when Ive used one before Sorry old bean I didn't mean to sound like a smart butt lol, your idea is spot on All the still saws I've used have this attachment for the dust suppression kit, just don't put the tap on full blast low or else you end up with a slurry shower lol , Flynny Quote Link to comment Share on other sites More sharing options...
Dave-G Posted October 2, 2015 Report Share Posted October 2, 2015 Might be easier to put some guttering round the roof - or undersling an eaves extension sort of thing so the rain flows off beyond the slabs. Quote Link to comment Share on other sites More sharing options...

scotslad Posted October 2, 2015 Report Share Posted October 2, 2015 U will be easier with a 9" grinder if space is tight and the daimond blades cut throu slabs no problem. The cheap ones arenae that deat to buy either, i've had my cheapy one for years ad its done a serious ammount of work But u might still struggle to get the slabs cut tight enough in. Might be worth also putting some guttering or even a piece of timber to take water further away from shed Quote Link to comment Share on other sites More sharing options...

It was quite an old one, probably pre 15 year's old. They certainly are a beast. Quote Link to comment Share on other sites More sharing options...
activeviii Posted October 3, 2015 Report Share Posted October 3, 2015 Don't bother cutting slabs. Go get your self a roll of brick damp proof course and tack under the last row of shiplap. Rain will run down, over the DPM and off into garden. Easier than trying to cut slabs Quote Link to comment Share on other sites More sharing options...
imissalot Posted October 3, 2015 Report Share Posted October 3, 2015 (edited) Seal edge off shed and slabs with a sand and cement angled finish (cross section would be a 3 inch triangle) Edited October 3, 2015 by imissalot Quote Link to comment Share on other sites More sharing options...
