As a homeowner, you don’t just have to worry about your own concrete slabs; you should be concerned with the slabs that make up the street that goes past your house.
During colder months, your street’s slabs contract, opening up the joints between them. Those joints then become filled with pebbles and other debris. Then, when the warm weather returns, the slabs expand again – only the joints that were designed to absorb this expansion are now filled with material that won’t compress. This leaves the expansion pressure nowhere to go except up your driveway. This “street creep,” as it is known, exerts incredible pressure on your home and can cause all sorts of problems.
