How to seal a garage?

[Acheron]

Ive got a garage big enough for a car, however the back of the garage is at a slope and the water runs to it. i've sealed it with gutter sealant, normal sealant, and the sealant left over from sealing the walls and roof that came with the garage, still the water pisses in.

ive got about 3-4ft encroachment into the garage of a puddle of around an inch deep when the rain is heavy.

any ideas?

The garage is pretty much this;

You mean the back end is underground a bit, the soil is up against the walls?

Best dig a french drain. Basically a trench filled with gravel to channel the water away.

The back of the garage has about 1ft of flat concrete, but at a slight run down to the back of the garage. After that theres a sharp incline of about 3ft which is all soil and bushes.

The gutter is also at the back, so the water from the soil, the water than lands on the concrete from the rain and the water from the gutter ends up collecting against the back of the garage and coming in underneath.

The answer lies within the question grasshopper. Re-route the gutter downpipe, and dig a drain (Aco, Google it) to take the water away.



Or, if that is not possible, make a small concrete 'ridge' an inch high,around the garage, to guide the water elsewhere.

Never thought of digging it up at the back. Cheers guys
