We are building the round pen from scratch and are reading page 32 in "From my hands to yours" where Monty recommends a well-drained area covered with a clay-like sub base of approx 6 inches as second layer under the 2-inch coarse sand surface. "Clay" traduced into Spanish is "arcilla" and traduced into German "Lehm, Ton". In both languages it is something which gets hard?!
Is there someone who can help me with a definition of clay? The round pen will be without roof and we live in a very rainy area (like in the UK :))
Thank you very much in advance.
