Drainage of the ground around your home is likely one of the last things you consider when you're shopping for a property. However, many of the projects you must undertake as a homeowner to prevent basement flooding, soil erosion, and other serious problems involve a lot of digging and the use of heavy machinery. Find a good source for healthy top soil and you can save a lot of work by building up with new material instead of digging down. Try these four top soil based landscaping projects to contain your drainage issues.
Simple mounds of firmly compacted soil known as berms are great for preventing water from flowing down a slope or towards a structure. Berms should stretch across a slope of a landscape and not run down it. This is referred to laying out the earthwork along the contour rather than with the contour. You should remove any weeds or grass growing where you plan to build up the berm mound, but there's no other need for dig if you're bringing in top soil rather than digging a drainage ditch to provide the soil. After compacting the soil, you can grow small plants or grass to help hold the earthwork in place and make it more attractive.
Leveling a Yard
While most land grading services pay close attention to the slopes around the future home site, they often leave depressions or trenches in other parts of the yard that nevertheless cause unsightly damp areas during periods of heavy rain. Leveling out low spots in a yard is easier than you think if you're patient enough to wait on new grass seed to sprout and establish itself. Use a sod removal shovel to cut up layers of existing grass, then rake the existing soil and remove any rocks or other debris that is also contributing to a bare surface.
Bring in top soil that is blended 50/50 with compost or another source of a well-decomposed organic material. You may have to mix small batches of compost and top soil together yourself, but make sure you request a screen soil product with sticks, stones, and other material removed. Many top soil products include these extra materials because it's not a problem in berms and other earthworks, but you want a finer mix for leveling out a lawn area where turfgrass needs to grow.
It's possible to add 1/2 an inch of top soil and compost at a time over existing grass instead of removing sod and re-seeding the areas. However, it takes years to fill in a depression this way. It may take a year or two for seed to reach a mature state, but you'll be able to enjoy better drainage for that entire time as well by leveling out low areas all at once.
Installing Bench Terraces
Eroding slopes can be transformed into valuable garden space with some edging material, such as cedar planks or landscaping timbers, and a few inches of top soil added into the space. This utilizes a method known as bench terracing which allows you to build up over the surface of a slope rather than digging down and disturbing the surface below. Adding top soil also allows you to create a reverse bench so that the surface of each terrace bed angles downward towards the slope itself. This creates a natural lip to prevent water from running over the edges of the terrace and down the slope.
Establishing a Thicker Lawn
Finally, adding a few inches of healthy screened top soil to a bare spot in your yard greatly increases your chances of establishing a thick and green lawn. Healthy grass acts like a sponge to suck up excess moisture in matter of minutes, eliminating puddles and preventing erosion on slight slopes. Bulk orders of top soil give you a chance to level your yard and add soil for seed to take root in at the same time.
