The term “drain benching” basically means the built up area of concrete (bricks in some cases) above the level of a pipe within a manhole. Over time this slowly wears away and becomes a place that toilet paper and solids build up eventually causing a blockage, pre formed plastic manholes are an exception.
We can re new the benching of your manhole and prevent future problems, if we can be of any assistance in Harrogate or the surrounding area please contact us on : 01423 819319
