ENVIRONMENTALLY FRIENDLY CONSTRUCTION

Low impact building with technical specifications.

Usage:

Eco-construction, old buildings, wooden-frame houses, farm buildings, etc.

Applications

Hemp mortars and concretes for:
  • Wall insulation
  • Floor insulation
  • Roof insulation
  • Renders
  • Hemp blocks
  • Permeable slabs

Main Advantages

  • 100% natural hydraulic binder
  • Ideal with hemps and limes
  • Rapid form removal
  • Rapid reuse (floors)
  • Permeance of the structures

Usage Solutions


1. Hemp Concrete

Insulation of flooring, walls and partitions, roofing, insulating coatings and lightweight screeds

Advantages

Hemp mortars and concretes for:
  • Quick removal of form panels
  • Quick availability of floors
  • Thickness and high weight in a single laying (10cm)

IMPORTANT:

  • Before using, refer to the guide for applying hemp concrete and mortar
  • Tempo is essential for presented applications to observe the pace of work related to eco-construction
  • In outside finishing, applied by machine or by hand the fat lime plaster from Lime Green Products Ltd are compatible with Vicat hemp concrete. Refer to the manufacturer's technical data sheet
