How To Slope A Paver Patio Away From House

How to Slope a Paver Patio Away from House: A Comprehensive Guide

Creating a paver patio is a great way to enhance the outdoor living space of your home. However, it's crucial to ensure that the patio is properly sloped away from the house to prevent water from pooling and potentially damaging the foundation or interior of your home. This guide will provide a comprehensive breakdown of how to slope a paver patio away from house, covering essential aspects from determining the slope to installing the pavers.

Determining the Slope

The first step is to determine the appropriate slope for your patio. The ideal slope is 1/4 inch per foot, which means that for every foot of distance from the house, the patio should be 1/4 inch lower. This slope is sufficient to allow water to drain away from the house without creating an excessively steep or slippery surface.

Excavating the Area

Once you've determined the slope, you need to excavate the area where the patio will be installed. Use a shovel or an excavator to remove the existing soil to a depth that will accommodate the pavers and a base layer. The depth of the excavation will vary depending on the thickness of the pavers and the base layer you choose.

Installing the Base Layer

The base layer is essential for providing a stable foundation for the pavers. It should be composed of a compacted layer of crushed stone or gravel. Spread the base material evenly over the excavated area and compact it using a plate compactor or hand tamp.

Setting the Slope

To set the slope, use a string line or a level to create a straight line from the house to the edge of the patio. Stretch the string line along the desired slope, ensuring that it is parallel to the house. Use stakes to keep the string line in place.

Installing the Pavers

With the slope set, you can begin installing the pavers. Start at the lowest point of the patio, which is typically along the edge closest to the house. Set the first paver in place, ensuring that it is level and flush with the string line. Continue laying pavers in rows, working your way up the slope.

Cutting and Fitting Pavers

As you reach the edges of the patio or encounter obstacles such as corners or curves, you may need to cut pavers to fit. Use a paver saw or a grinder to cut the pavers as needed. To ensure a snug fit, dry-lay the cut pavers in place before applying mortar or adhesive.

Filling Joints and Sealing

Once the pavers are installed, fill the joints between them with polymeric sand or mortar. Brush the sand or mortar into the joints, ensuring that they are completely filled. Allow the joints to dry and cure according to the manufacturer's instructions.

Maintaining the Slope

Over time, the slope of the patio may settle or shift. Regularly check the slope to ensure that it is still draining away from the house. If the slope has changed, you may need to adjust the pavers or re-set the base layer to restore the proper drainage.

By following these steps and considering the essential aspects discussed in this guide, you can effectively slope a paver patio away from house and ensure that it remains functional and aesthetically pleasing for years to come.
