hello there,
i have aquestion for you experienced people here. i have built a steel shed using box iron and cladding and placed it on a concrete pad. i am almost finished but my problem is that when it rains water will flow underneath the cladding and box iron. i have tried mastic and tapering in concrete against the box iron but still a slight leak.
i was thinking of either pouring concrete again thus raising the floor inside or laying down plastic sheeting, then putting battens down and laying marine plywood. then covering the plywood in floor levelling compound and painting it with epoxy garage floor paint.
what do you think? thanks in advance.
