4 Landscape Construction Tips for Driveways on a Slope in Oswego, IL

A sloped driveway requires some careful planning before landscape construction can begin on your Oswego, IL, property. The incline creates the need for thinking through erosion risks, durability of the construction, and other special issues that are not as pressing for flatter driveway surfaces.

Soil Preparation

When constructing a sloped driveway, landscape contractors will be initially concerned with the subsoil that lies underneath. It needs to be compacted to provide a stable base for the driveway pavers to rest on for years to come. Careful preparation and compaction of the soil will reduce the chance of the pavers moving over time.

When dealing with sloped driveways in a residential area, the soil should be compacted to at least 98 percent of the soil’s maximum density. This measurement is determined by a standard proctor density test. If the hill is extra steep, soil samples may need to be taken before work on the driveway begins. What may seem like an extra step can actually have a lasting effect on your landscape project by increasing the life of the driveway dramatically.

Permeable Fabrics

4 Landscape Construction Tips for Driveways on a Slope in Oswego, IL

Geotextile fabric is considered to be an essential addition when constructing a driveway on a slope. This is due to one of the main points of failure on a sloped driveway which is loss of structural integrity through erosion. When geotextile fabric isn’t in place, the subsoil underneath the pavers may begin to wash away, leaving a gap between the subsoil and the installed paver. It won’t be immediately noticeable, but over time, the driveway could begin to bulge and bow as the soil underneath it disappears.

When installing the geotextile, the fabric at the edges of the driveway will need to overlap by 12 inches. The fabric also needs to be installed without wrinkles as water could collect in any indentations.

Concrete Header

The concrete header is a structural must because it is another main line of defense against erosion and structural failure. This cast concrete beam runs across the downhill edge of the driveway to provide a stable base for the pavers to be laid upon.

Another extremely important step when working with the concrete header is the placement of the drainage mat. When installing the drainage mat, your contractor will make sure it is not torn, damaged, or filled with debris during construction.

Paver Installation

Placing pavers on a sloped driveway is a meticulous job. One small mistake can snowball into a big problem years down the road. It is encouraged for pavers to be placed at a 45-degree pattern for the benefit of proper surface water flow. This may require some special cutting expertise by your landscape contractor but may be necessary to reduce the risk of erosion. Careful thought will also need to be given to the joint widths and final compaction.
