MAPEGROUT BM: Low Elastic Modulus, Two-Component Concrete Repair Mortar
What is MAPEGROUT BM?
MAPEGROUT BM is a two-component concrete repair mortar designed to reduce the risk of cracking thanks to its low elastic modulus, which allows it to accommodate the natural movements of concrete. It is a professional solution particularly suitable for areas exposed to significant structural stresses.
This cement-based product consists of a powder component (Part A) and a special polymer liquid component (Part B). Its flexible structure enables it to work in harmony with concrete, balancing internal stresses, minimizing crack formation, and providing long-term durability. With its high bond strength, it can be used for both repair and protection purposes.
Technical Features
- Composition: Two-component system (Part A: cement-based powder mortar, Part B: polymer liquid additive)
- Elastic Modulus: Low – compatible with structural movements
- Consistency: Thixotropic – does not sag on vertical or overhead surfaces
- Application Thickness: Suitable for medium-thickness applications in a single layer
- Aggregate: Fine-grained
Advantages
Strong Adhesion
Provides excellent bonding performance to concrete substrates.
Movement Compatibility
Its low elastic modulus allows it to flex together with the concrete structure.
Crack Prevention
The flexible formulation helps limit the formation of microcracks.
Repair and Protection
Repairs damaged concrete surfaces while also providing long-term protection.
Easy Application
Components can be mixed according to the recommended ratio for quick and practical use.
Areas of Application
- Repair of reinforced concrete structural elements such as columns, beams, and slabs
- Vertical and overhead surface applications
- Repair of structural elements damaged after earthquakes
- Treatment of shrinkage cracks and surface deterioration
- Areas where maintaining structural integrity is critical
Application Instructions
The substrate must be free of dust, oil, paint, and loose particles and should be clean and damp before application. Part A and Part B should be mixed according to the ratios specified in the technical data sheet until a homogeneous consistency is achieved. The prepared mortar is applied using a steel trowel or spatula. Proper curing conditions should be maintained after application.
