INTRODUCTION TO WALLS
Building with Tradical® Hemcrete®should only be carried out by trained operatives. Training courses are available for self-builders and contractors.
Construction
Shuttered, cast and tamped
In this instance
temporary shuttering is fixed to the timber
frame with tubular spacers to form the finished
size and shape of the walls. The Tradical®
Hemcrete® is mixed in the required proportions together with the recommended amount of water. Standard Wall Mix is 1 bale
of hemp shiv (Tradical® HF) to 1.5 bags of binder
(Tradical® HB) with approx 40 litres of water
per bale of hemp. This material is then tipped
into the shuttering and lightly tamped into
place. After 24 hours the shuttering can
be removed.
Spray applied
The Tradical® Hemcrete® is mixed
in the required proportions together with the recommended amount of water. Standard Wall Mix is 1 bale
of hemp shiv (Tradical® HF) to 1.5 bags of binder
(Tradical® HB), the water is added close to the nozzle
of the spray system by the trained operative. This material is then
sprayed against temporary or permanent,
single sided shuttering and flattened to the
required surface. After 24 hours any temporary
shuttering can be removed.
Drying
High humidity levels and low
temperatures can inhibit drying of Tradical® Hemcrete®
Careful planning and preparation
is required to minimise drying times through provision of proper protection to
drying Tradical® Hemcrete®from rain and frost. It can be appropriate to use
air movers, heaters and dehumidifiers to shorten drying times during wet
weather, cold periods, winter conditions or when building in exposed locations.
