Sand/Gravel Slit Drainage

Woodward Turf Care can carry out all your secondary drainage needs. Sand/Gravel Slit drainage is used on sports turf to improve drainage where a primary piped drainage system is already in place. The Sand/Gravel slit drains intercept the surface water and move it rapidly into the primary pipe drains.

Sand/Gravel Slit drainage is usually carried out at between 250 and 350mm deep, 50mm wide and at 1 or 2 metre centres. The trench is usually back-filled with 2-6mm gravel and topped off with sports sand.
