Conclusions
“We are of opinion, having regard to the fact that the house at Newlands Corner (Guildford four miles) has weathered the winter, without showing any signs of dampness, that pisé de terre will make a thoroughly dry house.
“We consider that the tests made are satisfactory, and prove that this form of construction is of a sufficiently sound nature to be employed in the building of houses. With really suitable material, such as a light brick-earth or marl, it is considered that the results already obtained might well be 100 per cent. better.”
We are informed that additional tests are now proceeding with regard to the water-proof and weather-resisting qualities of Pisé, the results of which will be duly published.
