Water seeping into garage floor after and during rain

[claudeballs]

Help!!

I have block paving on two sides of my garage (built on to side of house).

When it rains, water starts to come into the garage on the sides where the block paving is. There is a damp proof membrane two bricks up from the floor of the garage and the block paving is one brick below it on the outside. It is also getting in under the double-glazed garaged door.
How can I stop the water coming into the garage ? Can I remove the row of blocks that are immediately against the walls, dig down (how far ? ) and fill in with Pea shingle ?

Can't quite picture this, is a photo possible?

DPC is 2 bricks above floor inside and 1 brick above pavers outside therefore pave is 1 brick Above inside garage Yes you could create a Drain Francais with shingle but a purpose built channel system would be better..I was in Wickes last night looking@ them (spooky) This would be better as pavers need to be contained, or they can move, (specially as we`re in a drought)...some of mine are D/G door small one for people, not car....acess door

Nige, that's correct. If I do the Drain Francais option, how far down do I have to go before adding the Pea shingle ?

Well, I`d go down 2 course below dpc. And waterproof the outside wall with synthapruf from below the garage floor level to just below the level of the shingle in the french drain because, though the water will run thru` the shingle there will still be a damp atmosphere within the shingle bed.
