Diathonite Sismactive

The ecological mortar for structural and thermal reinforcement

The effectiveness of a new system

Diathonite Sismactive is the main focus of an innovative system that simultaneously guarantees seismic and thermal performances; a lime-based structural mortar M10 for reinforcing masonry with CRM systems (Composite Reinforced Mortar).

Compressive strength

Class M10

High compressive strength (10 N / mm²) capable of giving the wall greater consistency and stability.

CRM System

Composite Reinforced Mortar

Investment in the safety of people and enhancement of real estate assets.

Flexural Strength

2,3 N/mm2

It adapts to the geometries of the surface and to any seismic shocks.

Fire Resistant


Classified in class A1 according to UNI EN ISO 13501-1. No flame generation and no smoke emission.

Thermal Conductivity

λ = 0,065 W/mK

A high thermal comfort that guarantees a wall that is always dry.

CAM Certified

The best solution from an environmental point of view along the life cycle of the building, taking into account the availability of the market.

Low VOCs

Sustainable. The material has been certified for the low emission of volatile organic compounds into the environment.

Sustainability certifications

It identifies Diathonite Sismactive as a low environmental impact product with a sustainability that involves all phases of its life cycle.

Performance certifications

The CE marking recognizes that Diathonite Sismactive conforms to European construction standards and to the rules that regulate its diffusion and use.

The UKCA marking recognizes that Diathonite Sismactive complies with UK construction standards and the regulations governing its dissemination and use.
