Renovations or extensions can often mean a new slab is laid abutting an old one. There’s plenty to consider before starting work to ensure the junction is weathertight, strong and Building Code compliant.
Covering a concrete slab too soon can result in the floor covering being damaged. To get the timing right, it helps to understand what the various measurements are telling you.
