style of breeze block? I'm renovating an old outbuilding and am now fitting the roof, I've decided to fit some frame work onto the breeze block to hold the frame for the roof. The frame work i'm fitting to the breeze block is going to be taking a lot of weight so I need the fixings to be solid. I'm just a little unsure of the best fixings to use for the job. The breeze blocks the buildings are made of are the large ones with the two hollow sections in them, I thinkthey'ree hollow to fill with concrete after the build but thesearen'tt filled with concrete and it would be too expensive to do that now. So if anyone could help I'd be more thangrate-fulll. Thanks very much in advance. Paul
