Day 17 - Thursday 24 May - Installing longitudinal connecting drains

Having completely covered the whole pitch area with sand the next step is to cut narrow trenches approximately 150mm deep along the length of the pitch.   The trenches are filled with a coarser grade of sand.   Because the lateral drains contain gravel up to the surface of the soil level, the longitudinal trenches cut across the lateral drains allowing  water to drain off the pitch into the lateral drains.

The longitudinal trenches are spaced 50cm apart and are cut three at a time in each pass.
