01 / Overview
Quick answer
Manholes 70 mm is a Jawdah drainage access item identified by a 70 mm figure in its name. Its material, clear opening, load rating and what the 70 mm measures are not published. Confirm these with the Jawdah team, and provide floor or paving sections, traffic type and quantities so the item can be matched to your project.
Overview
Where Manholes 70 mm fits in the Jawdah range
Where the floor or paving above a drainage access point is thick, or where a cover must carry more than foot traffic, specifiers often look for a deeper or heavier manhole item. Jawdah's range includes Manholes 70 mm alongside Manholes 50 mm.
The product data names the item but does not yet describe it. The guidance below explains how to turn that name into a confirmed specification, which questions to ask Jawdah, and what information to supply with your enquiry.
Jawdah groups its manhole products under one category with two items, named by millimetre figures. Manholes 70 mm carries the larger figure. Beyond its name and its place in the drainage family, no technical description has been released for it.
That makes early contact with the manufacturer essential: the item can be quoted, but its details are set out per project rather than from a public data sheet.
02 / Performance
Checking the 70 mm figure against your floor
Ask Jawdah to state exactly which dimension the 70 mm describes. Then draw a section at the access point and mark the depth available between the top of the chamber and the finished surface, and the thickness of the finish that must sit in or around the cover.
A recessed tray that is too shallow forces a thinner finish that may crack; a tray that is too deep leaves a weak, thick infill. Matching the confirmed figure to the actual build-up avoids both problems.
03 / Applications
Situations where a deeper manhole item is usually examined
If the 70 mm figure turns out to describe a recess or frame depth, the item would be relevant wherever the surface layers above the chamber are thicker than a standard tiled floor. Typical examples in general practice are listed below; each should be confirmed against Jawdah's answer.
- Natural stone or thick porcelain finishes in lobbies and malls.
- Tiles on a thick mortar bed rather than thin adhesive.
- External paving and courtyard finishes.
- Screed-filled covers in service areas and plant rooms.
- Locations where wheeled traffic crosses the cover.
Installation
Setting a deeper frame correctly
A deeper frame carries more finish and possibly more load, so its bedding matters. Bed it on a continuous mortar layer, check level in both directions, and allow the bedding to cure before traffic passes. For infilled covers, compact the infill well and avoid bridging finish across the cover-to-frame joint.
Selection pitfalls
Errors to avoid with Manholes 70 mm
Most problems come from ordering on the name alone.
- Choosing the 70 mm item only because it is the larger figure.
- Not confirming the material for external or wet locations.
- Ignoring vehicle traffic when no load rating is published.
- Omitting the finish type, which drives the recess depth needed.
- Mixing 50 mm and 70 mm items in one BOQ line.

What the Jawdah data includes
The product data includes the item name Manholes 70 mm and its sister item Manholes 50 mm. It does not include material, opening or frame size, cover style, load class, sealing, finish, weight or documents for this item. These are recorded as data required and are provided by the Jawdah team on request.
Materials
Material questions to raise
Manhole frames and covers in the wider market are made from several materials, including stainless steel, galvanized steel, ductile iron and aluminum, each with different weight, corrosion behaviour and load capacity. Jawdah has not stated the material of this item.
State the environment in your enquiry: hygienic interiors usually call for stainless steel, while external paved areas focus on load and corrosion protection.
Comparison
How Manholes 70 mm relates to Manholes 50 mm
If both figures describe the same dimension, Manholes 70 mm offers the deeper option and Manholes 50 mm the shallower one. Until Jawdah confirms this, compare the two items only after you have their confirmed details side by side.
General background on chambers, frames and cover types is on the Manholes category page.

06 / FAQ
Frequently asked questions
A manhole item in Jawdah's drainage range, listed alongside Manholes 50 mm. Its specification is confirmed per project.
That is not stated in Jawdah's product data. The figure could describe a recess depth, a frame height or another dimension; ask Jawdah to confirm.
It may be, but no material or load rating has been published. Send the paving build-up and traffic details for confirmation.
The clear opening is not published. State the access size your maintenance team needs in the RFQ.
Possibly, if the figure describes a recess depth and your stone and bedding are thicker. Confirm the meaning of both figures with Jawdah before deciding.
Sealing details are not published. If the cover will be indoors over foul drainage, request a sealed design in your enquiry.
