What Are the Paver Stones Under the Deck Steps?

Pavers

• "Pavers" is broad term that can be used to describe any number of stones, tiles or concrete blocks used in landscaping. Many times these pavers are used to create patios or as the exterior barriers for flower beds and other landscaping projects. Some are even used to build decorative retaining walls. Pavers are generally larger than bricks, although bricks are sometimes used in a similar capacity.

Stability

• One of the primary reasons you may see pavers installed under the steps on your deck is to provide them with a stable base. The constant weight of people walking up down the stairs may cause the stairs to sink into the ground over time. Properly installed pavers can help prevent this from happening by providing a base for the stairs to sit upon.

Weed Control

• Another possible reason you may find stone pavers under the steps of your deck is to control weeds. Stone pavers tend to be heavy and will generally kill the grass and weeds underneath them if left in place. If the steps are sitting directly on the pavers, the weight and pressure of foot traffic will also help to keep the pavers pressed into the ground and prevent weeds from popping up.

Installation

• If you're building a deck for your home, or simply want to fortify the foundation under the stairs of your existing deck, pavers can provide a suitable solution. First, dig out a small layer of top soil, creating a dirt base about 1 to 2 inches deep. Smooth the dirt with an ordinary garden hoe, then cover with a layer of sand. Compact the sand into the ground with your feet or a tamper, making it as level as possible. Install the pavers by gently easing them slightly into the sand. Try to keep each paver level with the next. The sand will serve as a sort-of dry mortar to help hold the pavers in place.
