Repair Mortar Manufacturing Plant: Scope and Setup
Repair mortar is a high-strength, low-shrinkage cement mortar used to rebuild damaged concrete and masonry, such as spalled beams, columns, slabs and edges. Most repair mortars are polymer-modified cement products with selected fine aggregates, shrinkage control and, for reinforced concrete, a corrosion inhibitor. They are supplied as dry powder in bags or small pails and mixed with water on site.
A repair mortar plant is a dry blending plant with tighter controls than a plaster or putty plant. It covers raw material storage, accurate weighing, careful dosing of small additives, blending, sieving, packing and testing. The product is used in structural work, so batch accuracy and test records matter.
Structural repair mortar
A high-strength mortar for load-bearing members. Standards such as EN 1504-3 group repair mortars by class, with the higher classes used for structural repair and the lower classes for non-structural repair.
Non-structural repair and patching mortar
A lighter mortar for patching, levelling and finishing damaged surfaces where structural strength is not the main requirement.

Machinery for a Repair Mortar Plant
The repair mortar plant machinery depends on the product, the batch size and the level of automation. The core machines are listed below.
| Machine | Used for |
|---|---|
| Weighing and batching scales | Accurate batch weights of every ingredient |
| Additive micro-dosing unit | Adds small quantities of polymer, inhibitor and shrinkage control |
| Mortar mixer (ribbon or paddle type) | Blends the dry mix to a uniform product |
| Sieve or sifter | Removes lumps and oversize grains |
| Bagging and packing machine | Fills and weighs bags or pails |
| Dust collection system | Keeps the work area clean and safe |
| Quality lab with strength and adhesion tests | Checks the cured mortar |
This is the repair mortar plant machinery list for a new unit. We size every machine from your batch plan and site.
Plant Layout and Production Capacity
Repair mortar is made in a clean, dry hall, with a flow of aggregate receiving, screening, weighing, dosing, blending, sieving, packing and dispatch. Keep additives in a labelled store and separate from the aggregates, so that dosing errors cannot happen.
Repair mortar production capacity is described in more detail below. A repair mortar production line is laid out to move material in one direction, with space and power left for a second line.
Capacity is the batch size multiplied by the batches per shift. Repair mortar is made in smaller, more controlled batches than plaster, so choose a mixer size that gives good accuracy, with a bag or pail packer that matches your pack sizes.
How we size a plant
- Your product list and sales target
- Batch size and batches per shift
- Floor area, height and power at your site
- Packing sizes and storage days
- Room for later expansion
Repair Mortar Manufacturing Process: Step by Step
The repair mortar manufacturing process follows a fixed order of steps, and each step ends with a check before the next begins.
Polymer modified repair mortar
- Dry and screen the aggregates to the grading chosen
- Weigh cement, aggregates and fillers to the batch plan
- Dose the polymer powder, shrinkage control and corrosion inhibitor through the micro-dosing unit
- Blend to a uniform mix and sieve
- Test a sample for strength, adhesion and shrinkage, then pack in sealed bags or pails
Quality checks
- Particle grading and mix uniformity
- Workability and setting time
- Compressive strength of the cured mortar
- Adhesion to concrete
- Shrinkage and cracking behaviour
Raw Materials Required for Repair Mortar Production
Raw materials decide the quality of repair mortar, so each one is bought against a specification and checked when it arrives.
Binder and aggregates
- Cement of stable quality, kept dry
- Selected fine aggregates with a controlled maximum grain size
- Silica fume or other fine fillers where the formula calls for them
Additives
- Redispersible polymer powder for adhesion and flexibility
- Shrinkage-reducing additive and a water reducer
- A corrosion inhibitor for repair of reinforced concrete
- Fibres where the formula needs them
Sourcing and storage
Moisture and weighing errors spoil repair mortar, so dry the aggregates, keep cement and additives sealed and calibrate the scales regularly.
