We have partnered them as supplier since we began trading many years ago.Recessed manhole covers are a relatively modern invention. Using a simple lift-out tray concept, they enable modern inspection chambers or old manholes to be accessed from within a patio, driveway or garden area without the need for an unsightly steel or cast iron cover that stands out from the surrounding finish like a sore thumb.Block paving, patio slabs, concrete or tarmac is laid within the recessed tray, matching the material finish all around the cover. Paving slabs and block paviors are aligned so that the sand or mortar lines line up exactly with the adjacent products, making the recessed cover almost invisible.Most recessed covers feature integral lifting keys to avoid the need to disturb the infill. A variety of weight loading options and a wide range of sizes are available from our stock.The technical specification sheet for this product can be viewed and downloaded by clicking here.
