Specification and guidance notes for F2 Pipe Subsoil Drain Construction. It refers to pipe subsoil drains including the construction of trenches; the supplying and laying of perforated pipes of the specified type and size; the jointing of the pipes; the supplying and compacting of approved backfilling materials; and the construction of connecting and outlet drains. Subsoil drainage can improve the soil moisture relationship by keeping the ground water-table well beneath the paved surface.
