House skirting question!!!?

My husband and I are buying a 50 or so year old house. It doesn't have regular siding but the shingle siding. Anyways, the house is on pier and beam and over 50+ years, the house has shifted and so the original concrete skirting (I guess that is what you would call it) has broken and busted in many places around the bottom of the house. I was wondering though what types of skirting I could use? We don't want concrete, concrete board or flashing. We want something like the faux rock or something like that but I haven't been able to find it on any website. Help please!! If you could direct me to some websites or different products? Home Depot and Lowes have nothing I am looking for. Thanks!
