FridgeFreezer Posted July 3, 2007 Share Posted July 3, 2007 LR content - it's for the floor of my "will be built soon honest" shed/workshop/garage/evil lair. At the moment I have a big concrete slab in my back garden, full width (about 24') and about 12' deep, however it's not level and as a result a huge puddle forms right where it would be most convenient to lie under the landy and change the oil. It's only maybe 1" deep but about 10' diameter on a bad day and I'd like to make it go away. Can I use regular concrete over the top of it (bearing in mind it doesn't want to be more than 1" deep) or is there a leveling screed I can use (i used a little bit of it indoors where my fireplace used to be, but is it suitable for a workshop floor?).

honitonhobbit Posted July 3, 2007 Share Posted July 3, 2007 Jon Pop down to your local Bradfords (or insert local builders merchant) and but a tub of 'Self Levelling screed' Not cheap but very good, it will also take floor paint well Quote Link to comment Share on other sites More sharing options...
SOA 93 Posted July 3, 2007 Share Posted July 3, 2007 Self levelling isn't really suitable for for that sort of depth, you could use it and build it up in layers, and its not 'self levelling' you will need a float to spread it about. What about a big masonry drill about 20-25mm and drill through the slab once or twice in the centre of the puddle, so it can drain away. Once you've got a roof on you won't need to worry about it Andy Quote Link to comment Share on other sites More sharing options...
gsr341 Posted July 3, 2007 Share Posted July 3, 2007 What about a big masonry drill about 20-25mm and drill through the slab once or twice in the centre of the puddle, so it can drain away. have to be a long drill and about 12' deep Quote Link to comment Share on other sites More sharing options...
SOA 93 Posted July 3, 2007 Share Posted July 3, 2007 have to be a long drill 25mm 450mm long masonry drills are standard fare for any plumber, pick one up at any merchant or borrow from a friendly plumber, hire shop's will even hire you one. I don't doubt its 12" at the edges, but that does not mean it will be in the middle. Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted July 3, 2007 Share Posted July 3, 2007 I don't doubt its 12" at the edges, but that does not mean it will be in the middle. Knowing fridges luck it'll be a cap for a pit shaft, and about 6 foot thick in the middle Quote Link to comment Share on other sites More sharing options...
Holyzeus Posted July 3, 2007 Share Posted July 3, 2007 latex wont be any good for that depth, the hole idea is good. could also try a strong watery mix of cement and screeding sand say ratio of 1:2 to build it up, dampen the area down first use a float or laying on trowel Quote Link to comment Share on other sites More sharing options...
pinny Posted July 3, 2007 Share Posted July 3, 2007 a couple of years ago we done a load of caravan bases down here in essex using a fiborous mix basically concrete with fibre doesnt need any reinforcing and holds toghether well at thin layers maybe worth a look failing that unibond the slab and use a strong sand and cement mix Quote Link to comment Share on other sites More sharing options...
Steve Hiatt Posted July 3, 2007 Share Posted July 3, 2007 FF, nothing cheap will stick at that thickness and be strong enough to jack off. As I sell concrete I guess this is my specialist area Also as the slab is outside frost would be a problem. As has been said drill a hole/drain or cut a channel with a grinder so it drains away .............. or buy a broom ............. or buy some even bigger tyres so that you can maintain it stood up.

Yeah the "make a channel" option was being considered as I'd rather it runs off onto my lawn than create an underground pond under the slab Bigger (and quieter) tyres are on the shopping list, and may even happen soon.

swanny Posted July 3, 2007 Share Posted July 3, 2007 hello best thing to do is cut some grooves in it were puddling apply a genorus coat of pva glue neat our dilute it a bit. then get some bags 25kg ones. river sand grano dust cement. mix it 2 bags sand 2 bags grano 1 cement and 1/2L pva spread out on floor with steel float feather out edges with wetish mix. let set for 2hrs then remove any trowel/float marks. it drys rock hard. jobs a good en. clean tools swanny Quote Link to comment Share on other sites More sharing options...
Cl10473 Posted July 4, 2007 Share Posted July 4, 2007 if it 10' wide, get a 10' or 12' 2x4, mix up some concrete, and use the 2x4 to level it out. This of course assumes that the slab is somewhat level at the edges(where the 2x4 would be straddling). A second person here comes in very handy. Nothing a 6pack can't of come. Hope that help, good luck. Quote Link to comment Share on other sites More sharing options...
jericho Posted July 4, 2007 Share Posted July 4, 2007 It will soon be summer,so puddles won't be a problem. Get that workshop built before winter! Drill a hole,cut a channel,or add another layer of concrete or screed over the whole surface (at least 2"). Quote Link to comment Share on other sites More sharing options...
