“Pavers are a very versatile walkway paving material. They can be used to create a simple path or an elaborate entry walkway. Walkway pavers come in many shapes, colors and textures and can be laid in a variety of patterns. They are typically placed over a bed of compacted soil and gravel, so you don’t have to worry about cracks.”


“The four most popular patio styles are dining patios, living room patios, bistro patios and sundeck patios. Each of these patio styles serves a different purpose. You can incorporate one, or all of them into your yard, depending on how much space you have available.”
