When motivated, a rat can almost certainly make its way into your home using its powerful jaws.
Rats leave dirt, waste and grease in their paths. They are also capable of chewing through wood and concrete. Rat holes are both unsightly and dangerous; not only do they allow entry to a variety of other pests, but they also can lead to short-circuit fires if the rats gnaw on electrical wires..

"Rats can certainly gnaw through concrete and metal, most normally soft metals such as tin, aluminium, copper and lead, but I have seen gnaw marks on steel, various hard plastics such as waste pipes and terracotta pipes — as well as concrete walls." Alice Sinia, an entomologist and technical advisor with pest control ...
When there are no animals in the nest, fill it with concrete or sand. If possible, locate the main entry hole and all of the exit holes and pack them full. You can pack steel wool or hardware mesh that rats can not chew through into the hole as well. Be sure all the rats are out of the burrow.
That said, you might be curious to know, "Can mice chew through concrete?" The answer is yes, but only if the concrete is not cured properly. There is one material that mice tend to shy away from – steel wool.

Rats, like mice, can squeeze through impossibly small gaps (anything down to the size of a 10p coin) and should never be underestimated as to their versatility and persistence when trying to enter a building.
University of Nebraska researchers found that rats can scale walls made from specific materials. These materials are concrete, brick, wood, sheet metal, plastic, stucco, and drywall. Although all rats are good climbers, some are better than others.
to eliminate sources of food, shelter, and water. Denied food, rats will turn to killing and eating each other, further reducing the infestation. Rats cannot live without food, water, or shelter.
