How To Install A Garden Drainage System

How To Install A Garden Drainage System

You need a good system that ensures the drainage of the yard is optimal. A constantly wet garden is a perfect ground for mold, moss, and mildew growth. Ensure the garden is appropriately graded to ensure it does not get eroded over time. There are different ways of keeping the plants looking healthy with no soggy or muddy spots. A garden drainage system helps move water out of the packed soil areas. It allows your garden to bounce back to life.  

Watch for early signs of poor drainage like water taking two to three hours to drain after heavy rain. It means you need to install an underground drainage system. According to Drain Cleaners Dublin the underground drainage systems are gravel-filled trenches or drainpipes. The drainage systems capture and eliminate excess water from the garden. Excess water can come from a stream nearby, a ditch or the gutters. The water can be channeled to a dry well.  

Installing a drainage system 

Locate the place where the garden us retaining plenty of water or water is standing on the soil for at least an hour.

Stride along the wet area and mark a spot for the dry drainage hole. Choose two drainage spots. Use a stick to mark each spot – place holes 3-6 feet from the center of the wet area.  

Dig 1-foot wide, 3-foot deep holes at those drainage locations. Scoop the sod off before you start to dig. 

Remove the surface grass, start from the wet areas and work towards each of the drainage holes. Make the line one foot wide and repeat the process for each wet area.  

Excavate soils along each line as you dig to a depth of 10 inches to form trenches.  

Scoop the soil out of the trench to make a slope from the wet area to the dug drainage holes. The slope should be 1/4 inch for each 4-feet. Confirm with a 4-feet level.  

Add 2-inches of sand and gravel mix to the bottom of your dug trenches. The materials allow water to flow freely. The sand fills the large gaps to prevent the soil from working its way into the area.  

Place 4-inch diameter perforated pipe in the dug trenches with the holes facing down.  Place slip mesh sleeves over the perforated pipes so that soil, sand and other small debris don’t clog the holes.   

Fill the sides of the pipes and the top part with sand and gravel mix. Add the materials to a 2-inches height above the pipe.  

Add 2-inches of sand above the grave to bring the trenches back to surface level. Place your sod back over the sand. 

Add more gravel and sand mix to the drainage holes until it is atop the trench where the 2-inches of sand starts. Add 2-inches of sand before placing the sod on top.  

Materials you need:

  • Level
  • Sand
  • Shovel
  • Mesh pipe sleeves
  • Gravel
  • 4-inch diameter perforated pipe

Your garden will be drained effectively, and your drainage problem will be solved.   Rarely do homeowners encounter unsolvable problems like low water table that can push water up from underneath. If you find yourself with a low water table situation, consult a pro. Most turtle lovers wish to have a turtle on their garden. In these situations, designing drainage should have special consideration. If there is a turtle tank in the gardens people love to adjust turtle tank filter with the drain.
