• Hemp is easily grown without the use of pesticides
• Low amounts of energy used in the production of Hemp Shiv.

• Helps to keep internal humidity levels within the 40-60% range which inhibits the growth of viruses and bacteria
• Non-flammable
• Resistant to rodents, insects and fungi
• Visually attractive – any shape can be formed with Hempcrete.
• Light-weight & Recyclable
• Sustainably produced – Fast growing, Hemp crop is grown annually.

Hempcrete:  Add Coarse Hemp Shiv, Natural Hydraulic Lime (NHL) 5.0 and our Lime Putty Mortar (see directions below) to cast in situ walls of various thicknesses and shapes.  Hempcrete is self-supporting, but not load bearing so it’s usually formed around a softwood timber frame. Hempcrete can be used in the construction of floors and roofs, adding a breathable, insulating layer.

Restoration projects: In old buildings, Hempcrete is used to replace damaged or missing infill.  When used internally Coarse Hemp Shiv adds an insulating and breathable render to stone walls.

For internal hemp/lime plaster we recommend mixing Natural Hydraulic Lime (NHL) 2.0 and Hemp.

Hemp comes in a 44 lb (20kg bale) and has 200L of Hemp per bale. Imported from Roundtower.
