First of all i know NOTHING about building work. i have a detatched concrete pre-fab garage and the floor level in the garage is lower than that of the surrounding yard. as a result water is getting in at the part where the wall meets the floor. i know your supposed to dig trenches etc outside but im not a builder and certainly cant afford one. Cani simply seal it from the inside with a bitumen sealer or will that not work? thanks
