Oldcastle 24x30 Diamond Slab Natural | The Home Depot Canada
Rated 5 out of 5 by mattbg from Good for resin shed foundation I used these as the foundation for some resin sheds atop a levelled bed of limestone screenings. They are perfectly adequate for this job. Make note of the weight - these are about 100 lbs. each and large, so depending on your physical size, available hands, and equipment may be very difficult to move and place.
