All dimensions are approximate and may change during the lifetime of this catalogue due to the implementation of the Harmonised European Standard.
Seals are normally SBR complying with BS EN 681-1:1996. Other compounds such as Nitrile or EPDM can be supplied but may not be available from stock.
*Pipes supplied with an in wall joint - no bell socket (full flexibility at joint maintained).
CPM specialised Flexilift system for handling/jointing purposes for pipes DN1200 to DN1800 is available.
Lorries with crane offload facilities are available for pipes up to DN 600 upon request, although site assistance would be required on certain diameters.
When ordering pipes which may have to joint with pipes already on site or previously laid, particularly extensions to contracts, it is important to advise the sales office accordingly in order to eradicate any jointing problems.
Flexible jointed concrete pipes can be supplied with perforations.
CPM lubricant is advised for use on integral and superseal type pipes, CPM cannot guarantee that the jointing of concrete pipes with the use of other lubricants will be successful.

Short length and rocker pipes allow for any differential settlement between manhole and pipeline, short lengths of either spigot/socket butt pipes should be built into the manhole wall. A rocker pipe should then be laid connecting the short spigot/socket butt pipe to the incoming/outgoing pipe run, thereby incorporating a flexible joint close to the manhole. A rocker pipe should then be laid connecting the short spigot/socket butt pipe to the incoming/outgoing pipe run, thereby incorporating a flexible joint close to the manhole.
Branches 100mm and upwards can be fitted to all pipe sizes. Branches can be made from drainage materials other than concrete and are normally fitted to both full length and short length pipes to suit customer requirements.
Uni junctions are supplied fitted to pipes from DN300 up to DN1800 to suit 150mm diameter connections.The uni junction is produced by inserting a rubber gasket to BS EN 681-1:1996 into the main pipe at the factory, providing a watertight seal for the branch connection.
The uni junction is designed to suit 150mm supersleve clay pipes not slimline clay pipes. To connect to plastic pipes, an adaptor coupling from the clay to the plastic pipe will be required. Alternatively for certain plastic pipes an adaptor bush is available. Contact our Sales office for full compatibility details.

CPM offer a range of flexible jointed ovoid pipes for use in both foul and surface water applications.The ovoid pipe is manufactured and tested in accordance with the requirements of the European StandardBS EN1916 2002/BS5911-1 2002 including dimensional tolerances, crushing, hydrostatic, and joint test.
The ovoid pipe has better velocity characteristics at low flows than equivalent circular pipes, which provides:

Avoid damage when handling, especially to ends of concrete pipes, and never drag or roll pipes.
Always use correct craneage with purpose built lifting device. If ordered, large diameter pipes incorporate lift pins for which the propriety head link and chain is required (i.e. Flexilift).
Joint rings must be stored away from sunlight, heat or possible contact with any oils. Stack pipes on even ground on timbers to protect sockets and spigots, making sure the bottom row is securely chocked.
Using ‘Flexilift’ lifting/jointing chainsAvailable for DN1200 pipes and above
Use the equal length chains C1 and C2 for lifting and placing each pipe in the trench.
Connect the longer length chain, C3, to the pipe already laid and place the shorter length chain, C2 on the hook provided.
The pipe can then be jointed without moving the jib of the crane.

Jointing
Correctly position and bed the first pipe. Prepare the bedding for the second pipe and hollow out forincoming spigot to prevent bedding material entering the joint.
Ensure the joint ring (where supplied loose) is of the correct size, is not twisted, is correctly located on the pipe spigot and the right way round.
Ensure the pipe spigot and socket are clean and undamaged.
Lubricants must not be used where ‘G’ and Lamell rings are supplied. Lubrication is required with theEZ and superseal integral joint (use of CPM lubricant is recommended).
Ensure the pipe to be jointed is adequately supported. The spigot should be centred carefully in the socket before jointing is completed, making sure bedding material does not enter the joint at any time.
For more detailed information on jointing see CPM Drainage Systems ‘Concrete Pipes Installation Manual’ at www.cpm-group.com

The air test is not covered by the European Standard, but a pipe which complies with the standard willusually comply with the air test. Failure to pass the air test will not normally preclude the acceptance of the pipeline if a successful water test can be achieved.
Ensure the test equipment is in good condition.
Inflatable stoppers are recommended for ease of use.
The test should be carried out after every 3 or 4 correctly laid and jointed pipes prior to commencement of backfill.
A successful test is achieved if the equipment shows a fall in pressure of no more than 25mm after 5 minutes, having allowed a suitable period for stabilisation.
If the pressure falls sharply and the pipes appear to have failed, the following checks must be made before contacting CPM for assistance:
(a) Check the test equipment is in good condition (b) Check if the stoppers are leaking - use industrial soap around the edge of the stopper to provide an effective seal if necessary(c) Check the joint rings are correctly located
Dramatic temperature changes both inside and outside of the pipe could affect the air test.Reference should be made to BS EN 752.

CPM offer a range of reinforced precast concrete manhole units specially designed for sinking by the caisson method from 2000mm diameter to 4000mm internal diameter in varying depths (please see table).
This is achieved by using a shaft sinking system and is made in accordance to BS EN 1917:2002 and kitemarked where relevant to BS EN 5911-3 :2010.
Caisson Shaft Sinking System
Advantages of the system include:
Notes
4000mm chambers are supplied in two half sections, each weighing approximately 3180 kg per metre, for assembly on site.
The steel cutting shoes can be fitted to the base section providing a 20mm overbreak.
Cutting shoes with a larger overbreak can be manufactured upon request.
The 3660mm and 4000mm steel cutting shoes are supplied loose and in two sections.
Caisson lifting equipment is available for purchase from CPM on 01179 812791 or [email protected]
The caisson shaft sinking system was originally designed for use in microtunnelling, but is now more widely used for construction of pumping stations, wet wells and manholes, particularly in difficult ground conditions.

Manhole / Integrated Ladder System
20-21
Ease of InstallationThe Ladder Rungs are pre-fitted at 250mm centres into the chamber section, leaving only the Stringer, Locating Bracket and End Caps to fit. Minimal access to a confined space to fit ladder stringers, no lifting, drilling or temporary access required to chamber.
Flexibility The incorporation of the Ladder Rung in the manhole automatically takes account of the variation in depth to design.No bespoke ladder needs to be surveyed, ordered or manufactured.No equipment hire compared to fitting traditional galvanised steel ladder.
SafetyThe polypropylene polymer encapsulation gives high visibility and no sharp edges.The rung has a tread pattern to give good slip resistance.The stringer has a circular cross section designed to give a secure hand grip unlike a conventional ladder which isnormally too large to safely hold on to.
Quality Ladder Rungs are Kitemarked to BS EN 13101.The Ladder Rungs are reinforced with high tensile steel tube. The ancillary fitting brackets are made from stainless steel Grade 304 or 316.
Durability The chemical resistance of polypropylene can be considered equivalent to Grade 316 stainless steel.
Strength Ladder rungs pre-fitted to ensure factory controlled performance.
Product Standards The system has been designed and manufactured in accordance with the requirements specified in the following:BS EN 13101:2002 Steps for underground man entry chambers. BS EN 14396: 2004 Fixed ladders for manholes.
The CPM integrated manhole ladder system is an innovative product which has been designed to provide safe access and egress to precast concrete manholes, caisson shafts and inspection chambers.
Rungs are pre-fitted into the chamber to provide an installation which is quick, cost effective, reliable and safer than conventional ladders.
The system has WRc approval and meets the essential requirements of existing and new design codes in terms of dimensions and performance

After an extensive research programme, CPM introduced the 1200mm Perfect Manhole system in October 2009 to meet the challenges of modern day construction. Today it is available in 1200mm, 1500mm and 1800mm diameters and comprises of a monolithic precast concrete base (available pre-benched in any configuration within just days of requisition), a sealed chamber ring (with a thicker wall than a traditional ring), a rubber joint (so no tokstrip or similar product is required) and a sealed cover slab (supplied with your required access).
For other sizes please Telephone: 01538 380500 / Email [email protected]
This unique system of products combine to form the CPM Perfect Manhole system; designed and manufactured to last a minimum of 120 years that provides a sealed manhole system that gives up to 40% savings on green house emissions compared to traditional manhole construction and eliminates the need of ready mixed concrete to form the traditional base, chamber benching and further concrete to surround the manhole. A complete manhole can be installed in as little as 25 minutes, and making safe site practice a real winner when using the Perfect Manhole as it reduces the need to work in confined spaces and eliminates the need for wet trades resulting in rapid construction compared to traditional methods as well as a reduction in time for the excavation space to be open.

Perfect Manhole System / 1800mm
Typical Perfect Manhole Images
After the successful introduction of the 1200mm and 1500mm perfect manhole system, CPM has developed an 1800mm sealed manhole that can be used for precast concrete pipes up to 900mm diameter.
The system includes a cast-in base and incorporates the concrete butt pipes into the chamber base and pipe channel; this only leaves the benching to be completed on site. By leaving the benching out of the base element, the weight of the unit is reduced to between 5.0 and 5.5 tonnes depending upon the configuration.
Deeper manholes are accommodated by using a reducing slab to a 1200mm sealed manhole.
The 1800mm Perfect Manhole system can be supplied with either double steps or with an integrated ladder system which is available from CPM.
As the 1800mm sealed manhole system is a bespoke precast product, standard measurements cannot be given as each is individual.

Benefits of using a CPM catchpit and silt trap
Catch-pit/silt trap chamber systems
CPM Drainage has developed a range of Off-Site solution catchpit and silt trap manholes so why spend days constructing an in-situ catch-pit manhole on site when one-piece chambers are available now and can be installed within hours, not days!
The reinforced watertight one-piece structures offer greater design flexibility with a range of cored orpre-formed holes/cut-outs for inlet/outlet holes which come complete with seals.
Design options include:
1050mm to 3000mm standard tongue and groove complete with a cast-in reinforced base1200mm, 1500mm and 1800mm sealed manhole joint complete with cast-in reinforced basePipe inlet/outlet diameters covered by system 100mm to 1800mm
Reduced costs in construction time and on-site personnelSump depths to suit design requirementsAccommodates uPVC, twinwall, clay, ductile iron and concreteIncreased Health and Safety benefits as it reduces on-site constructionReduces wet trades for manhole constructionProduct is made and tested under factory conditionsEliminates extra transport and material wastage used with on-site construction methodsChamber bases are Kitemarked1050mm unit weighs less than one tonneBespoke design to suit customer requirementsStandard tongue and groove jointsGreatly reduced installation time on siteNone or minimal on-site fabrication required
Preformed Manholes
38-39
CPM has developed an off-site large modular manhole system that is designed to speed up the installation of the manhole whilst providing a safe working environment for personnel working within the manhole.

Accessories
Corner filler unit with straps and cleatsLifting and handling equipment
CPM L Shape precast concrete walling makes wall units easier to use as both faces of the unit are vertical and there are only two thicknesses of wall for the complete range.
CPM L shape retaining wall units are manufactured from C40/50 concrete with 50mm nominal cover to reinforcement.
They can be used in very severe exposure conditions as defined in BS 8110 Part 1 and severe exposure conditions as defined in BS 5400 Part 4. Stock units are suitable for loading from either side, with maximum loading from a level fill with a density of 19kN/m³ and 10kN/m² live load surcharge or sloped up at max. 30° to an equivalent height to the wall.A qualified engineer should check the foundation and wall stability.
Holes (32 dia) are provided to connect units with insitu foundation to provide stability against sliding and overturning. Holes in the wall stem provide lift points, corner filler strap cleat fixings and weep holes.
