About this deal

In cases where the topmost chamber section has to be removed, this too may be mortar bedded and will need to be separated from the lower chamber sections. Hammering in a chisel at the joint between the sections is usually sufficient to free the topmost section, but, as this section will no longer be required, it could be broken in-situ by hitting with a sledgehammer or similar. Again, care should be taken to prevent debris falling into the chamber. Manufacture: ISO9001 Quality system. F.A.C.T.A. (Fabricated Access Cover Trade Association) member.

Smart and discreet, our line of manhole covers is an excellent choice for any domestic or commercial project. Our bespoke paving manhole covers are perfect for driveways and patios that experience light traffic, with the majority of our manhole covers having a weight load bearing capacity of 10 tonnes. However, if you require a heavy-duty product, we also offer manhole covers appropriate for industrial use; capable of withstanding heavy traffic with a weight load bearing of up to 38 tonnes. If your latest drainage project requires a manhole cover and frame, we’ve got you covered here at Selco. We’re sure you’ll find what you’re after whether you need manhole accessories for commercial or domestic use. Note also the lifting eyes. These usually comprise a steel bar cast into a a small rebated area of the cover. In many cases, the rebate is filled with accumulated detritus and/or the steel bar has rusted away to nothing. If the lifting eyes are not suitable for use, then the cover will have to be removed by other means.Convertible manhole covers. These covers allow you to convert a drainage hole from one shape to another. IE. Circular drain to a square manhole cover or visa-versa. Solid top manhole covers. These include cast iron, plastic or steel covers but they all have a solid top. Once the level and alignment are correct, the frame can be haunched in place with additional mortar, which should cover the entire flange of the frame, but only extend up the side of the frame by 20-30mm, as sufficient room needs to be left to fit the paving or surfacing around the completed Tray and Frame.

A Class II mortar should be used (roughly 4:1) with a plasticiser to improve workability. There is no need to add a waterproofer or a hardening agent. Reseating a Crown Unit of this size will use more or less a 'full-bag mix' of mortar - that is, a full, 25kg bag of building sand, with 6-8kg of cement (Sulphate Resistant [SRC] is best, but Ordinary Portland [OPC] will be satisfactory) along with water and plasticiser. The mortar is spread along the top of the chamber sections, and tidied along the internal edge to reduce the amount of mortar that will fall into the chamber when the Crown Unit is dropped into place.As well as manhole covers, we have some manhole accessories to help you complete your drainage jobs to the highest standard. Our selection of manhole keys and drain cover lifters will help to lift manhole covers with ease. We also have water stop tap covers and frames, surface box covers, grid replacements and more.
