Rapid Set Bedding Mortar is a fast-setting, high-strength mortar for installing access covers, bedding highway ironwork and laying setts, flags and kerbs. Supplied in 20kg bags, its chloride-free formulation is suitable for bedding layers from 10–75mm. High early strength allows reopening to traffic after approximately one hour, subject to site conditions and application guidance.
Rapid Set Bedding Mortar combines selected sands, cements and additives to provide fast setting and high early strength. It is designed for installation and reinstatement work where reducing downtime is a priority.
Factory-produced for consistent quality, this chloride-free mortar is suitable for bedding layers from 10–75mm. It achieves a typical compressive strength exceeding 20 N/mm² after one hour, rising to approximately 60 N/mm² after 28 days.

Prepare the work area before mixing, as this mortar has a short working time.
Use a mechanical mixing method, such as a slow-speed drill and paddle. Carefully add one 20kg bag to 2–3 litres of clean water, depending on the required workability. Mix for at least 3 minutes until a uniform consistency is achieved.
Apply immediately after mixing and within 5 minutes. The mortar begins to set within approximately 10–15 minutes. Do not add water to revive material that has begun to set.
Surfaces must be clean and free from contamination. For best results, mechanically roughen the substrate, then saturate with clean water and remove any standing water.
Apply the mortar to the prepared substrate. Place the access cover frame onto the bed and gently tamp it to the required level, ensuring full support without voids. Enclose the frame flanges with at least 10mm of bedding material.
Float-finish and point exposed surfaces to a smooth finish, filling any voids.
Do not use below 5°C or where ground frost is present. Below 10°C, allow extra time before opening to traffic or applying further loads. Protect against rapid drying caused by strong sunlight or drying winds.
Store unopened bags in cool, dry conditions, raised off the ground on a pallet or shelf and protected from wind and rain.
Read the Product Data Sheet and Safety Data Sheet before use for full mixing, application, storage and safe handling guidance.
The MudMixer is a continuous-feed concrete mixer designed to mix bagged concrete, mortar and other cement-based materials quickly and consistently. Unlike traditional drum mixers, it continuously mixes material as you work, helping reduce downtime and increase productivity on site.
The name MudMixer comes from the construction industry’s long-standing use of the word mud to describe materials such as mortar, concrete, cement mixes and other wet construction products. While “mud” isn’t literally soil or earth, it’s a common term used by builders and tradespeople, particularly in North America, to refer to mixed cement-based materials.
Despite its name, the MudMixer isn’t designed for mixing soil or clay. It’s engineered to continuously mix a wide range of bagged construction materials, including concrete, mortar and sand-and-cement mixes, delivering a consistent, high-quality mix directly where you need it.
The name reflects the machine’s original roots, but its performance makes it an ideal solution for professional builders, landscapers, groundworkers, fencing contractors and anyone looking to mix concrete or mortar faster and more efficiently.
Simply load bagged material into the hopper, adjust the integrated water supply and the MudMixer continuously produces mixed material as required. There’s no need to stop and reload after every batch, making it significantly faster than conventional drum mixers.
The MudMixer is suitable for most pre-bagged:
* Concrete
* Mortar
* Sand and cement mixes
* Floor screeds (where manufacturer recommendations allow)
* Other cement-based bagged products
Always follow the material manufacturer’s guidance and ensure the product is suitable for continuous mixing.
While experienced DIY users can benefit from the MudMixer, it has been designed primarily for professional contractors, builders, landscapers, groundworkers and civil engineering teams who regularly work with bagged materials.
The MudMixer can process over 80 standard bags per hour under optimum working conditions, allowing you to keep working without the stop-start delays of traditional batch mixing. See the full MudMixer specifications or use our Concrete Calculator to estimate the material required for your next project.
Yes. The integrated adjustable water system helps deliver a consistent mix throughout the job, reducing waste and improving quality.
Yes. The MudMixer is designed so that one operator can efficiently mix material, allowing other team members to focus on laying, finishing, or other site activities.
Yes. Because the MudMixer continuously mixes material rather than producing individual batches, it can dramatically reduce mixing time and improve on-site productivity.
The MudMixer is perfect for:
* Garden rooms
* House extensions
* Foundations
* Footings
* Fence post installation
* Landscaping
* Patios
* Paths
* Kerbing
* Repairs
* Utility works
* Small civil engineering projects
It’s particularly useful where ready-mix wagons cannot access the work area.
Absolutely. One of the biggest advantages of the MudMixer is its portability. It can be wheeled into gardens, back gardens, alleyways and restricted-access sites where concrete wagons cannot reach.
The UK MudMixer operates from a standard 230V mains supply. Always use the correct power source and suitable extension leads for site conditions.
The MudMixer performs best when connected to a consistent water supply via hose, allowing the integrated water system to maintain the correct mix throughout operation.
Yes. Its robust wheeled design makes it easy to move around site and transport between jobs in a suitable van or trailer.
A MudMixer offers several advantages:
* Continuous mixing
* Less downtime
* Increased productivity
* Reduced labour requirements
* Consistent material quality
* Faster completion of jobs
For many contractors, the productivity gains can quickly offset the initial investment.
