This 600mm diameter concrete rocker pipe is designed to be part of a flexible joint system. Essentially, it is just a shorter version of a full size 600mm pipe, made with the same Spigot and Socket ends and integral seal for jointing to other pipes. It is intended for use when installing drainage at connection points with a structure or a manhole. The rocker pipe, when combined with Spigot & Socket Butt pipes, adds some flexibility between the main pipeline and the manhole chamber and thereby allows for settlement of the ground at different rates.
It is manufactured and CE marked in accordance with the European Standard BS EN 1916 Class 120 and British Standard Kitemarked to BS 5911 for use in both foul and surface water applications and is ideal for surface storm water and foul water systems.

Customer Advice: The use of CPM lubricant is strongly recommended with the CPM integral jointed pipe system. Non-compliance may result in installation problems for which neither JDP nor CPM can accept responsibility.
Sewers for Adoption (7th Edition) states that, when a manhole is installed along a pipeline, allowances must be made for any differential settlement between the manhole and pipeline. This can be achieved with a flexible jointing system. This involves concrete pipe being connected to a manhole with short lengths of either Spigot/Socket Butt Pipes and a Rocker pipe.
Butt pipes and rocker pipes allow for any differential settlement between the manhole and the pipeline, with the spigot/socket butt pipe being built into the manhole wall. A rocker pipe is then laid connecting the butt pipe to the incoming/outgoing pipe run, thereby incorporating a flexible joint close to the manhole. that will allow some slight movement of the IC and/or the rest of the drainage system without imposing and stresses onto the joints.
Marshalls CPM precast concrete pipes have a design life of 120 years, ensuring that lifetime costs are kept to a minimum. All precast concrete pipes are manufactured to class 4 (DC4) sulphate resistance in accordance with the recommendations of BRE Special Digest.
Key Features of CPM Concrete Products:
- Quality - Precast concrete drainage products are manufactured in accordance with the relevant BS EN 1916/7, BS EN 5911 and CE marked where applicable. Goods are certified by Quality Assessment under the Kitemark Scheme and ISO 9001:2015.
- Sustainability - Concrete pipeline systems are one of the most sustainable options available, they are manufactured from responsibly sourced materials, and can be made using recycled aggregates and cement replacements.
- Proven Strength - They have a proven life of over 120 years, in normal groundwater conditions, are not weakened by fire or moisture and do not lose their shape. They are resistant to DC4 and impacts such as jetting, so blockages can be cleared easily.
- Installed Cost Savings - Precast concrete pipes are rigid structural elements that do not always require a full granular surround, saving time in bedding and compaction. Excavated material can be reused and imported granular material can be reduced to a minimum.
- Durability - Due to the inherent strength and durability of the Marshalls CPM precast concrete products, they are highly abrasion and corrosion resistant and don't lose strength over time.
- Design Flexibility - Precast concrete drainage products can be used for a number of purposes, including sewerage and sustainable urban drainage systems (SuDS) applications such as stormwater attenuation and storage.
- Water Tightness - Concrete pipes and manholes are designed to be watertight and are tested to pressure levels equivalent to a 5 metre head of water.
- Fire Resistant - Concrete is naturally fire resistant.
