I recently installed a yardmaster metal shed in the garden. After a good
shower of rain the inside has huge wet patches on the concrete floor.

The sheds on a cement base with the top three or four inches being a mix of
one cement to four sharp sand and under that top layer, it's a mix of one
cement to three sharp sand and three Wickes ballast (gravel).

I have put a bead of *clear* silicone around the metal frame base of the
shed, but its obviouslly not enough to stop the problem. The Yardmaster
technical advice staff have advised using Shell Tixophalte 'seal and fix'
flexible bitumen sealer. I cannot get this in any local shops and a web
search usually reveals wholesalers who are mainly selling to the trade, and
it also looks to be expensive stuff to buy.

This link posted to the tinypic website will show the photo I took of the
outside edge of the shed

This picture below is on the inside and shows the metal frame base.

Would anyone advise a novice on; Would lashings of the clear silicone
sealant I have already bought be more or less as good to use as a bitumen
sealent? I would prefer to use a clear silicone since masses of a black non
setting bitumen would not look so good smeared all around the base. but if
bitumen is best then i guess i can pick up some at Wickes, rather than use
the Shell product?

Another aspect of this wet floor problem is that on the side of the shed
(where this photo was taken) the edge of the cement base is only three or
four inches from the shed base. But on the opposite two sides the width of
the cement base is about 18 inches one side and about 20 inches on the
other. My thoughts are, is the cement porous like blotting paper? thus
soaking up a lot of water on these larger flat areas and transferring it
inside the shed? If the cement base is in fact behaving like this, then i'm
guessing i would
have to seal the whole width of the base area around the shed.

Since i'm using this outside flat space for storing ladders etc, i would not
want to have to
walk on a 'non setting' type sealant or i guess even a silicone sealant. If
this blotting paper type activity is likely to be 'for real', what might be
a way to seal this part of the base please? Grateful for any other advice
on this problem,
thanks.

I would say the rain is running down what looks like a sliding door and
collecting the channel and getting in that way.

If you want a good sealant, then go for Gutter Seal from any big DIY Store.
It's mainly used on the joints of rain guttering, but it works perfectly for
the kind of joints you have to fill. It's just as flexible as the bitumus
one you have been recommended by the shed team.

But, saying that, I'd also have a look at what Baz is saying about the door
area. If it is the door, then you can use a bath seal strip or similar to
blank around the edges of the door. You could even use a good brush type
draught excluder to stop the rain blowing / dripping in past the edges or
the runners.

Either way you go with it, take your time and good luck.

As far as sealing, I sealed my garage with some stuff from the cement company.
I could not find the stuff anywhere including The Home Depot. Its almost like a varnish,
or at least it smells like it. I would want to put flashings attached to the shed to form
a drip edge away from the shed cement pad.

I'll remember to put a slight angle on the concrete if I make one.

I have had no problems with mine, however I modified the installation
instructions slightly. I fitted the base fittings, with plenty of
silicon underneath then assembled the garage on top.
