What is a “Pile Ring Beam” when referring to the foundations of an external garage ?
It will be a ring of concrete in the shape of the perimeter of the garage and will form the foundations of a garage should you wish to build one. The ‘Piled’ term is throwing me a bit as you’d generally not need to put piles in the ground for a garage because the loading in the foundation is comparatively low unless of course the ground conditions are poor. The ring beam will be buried so that if you choose not to build a garage you can just grass over it, if they’d laid it up to ground level you’d be left with a big grey concrete rectangle in your garden. When you decide to build a garage the foundation will be brought 6 inches above ground with two or three courses of blockwork then a damp proof membrane will be laid on top of those blocks and the garage walls will continue on upwards. I think they’re being genuine.
