hempcrete contractor | lime plaster and render contractor
This beautiful structure was first insulated using polystyrene foam, rubber seals, render mesh and cement render as per the local councils recommendations.
Water got into the panels and became trapped between the foam and the timber structure causing decay to the structure and damp patches on the wall.
The products that were recommended to the client were completely inappropriate and not at all vapour permeable.
Luckily the client could see the problems these un-natural materials were causing to the building and her own health. She discovered hempcrete and the rest is history.
The timbers had to be seen internally and externally due to the listing, they were very thin so only allowed for 100mm of hempcrete plus a very thin lime render and a thin plaster.

This technical advise was given to the client by the local council. This is how the building was first repaired- with foam and plastic seals. Moisture ended up getting in between the timber and foam and not being able to get out, the building suffered from condensation and damp and we had to replace all the foam with hempcrete not long after it had been installed.

as the job was quite small a standard cement mixer was perfect
