What is an Interlock Patio? A Complete Guide

An interlock patio is a popular outdoor flooring option that uses interlocking pavers to create a durable and visually appealing surface.

Homeowners often choose interlocking pavers for patios because they offer a blend of strength, style, and easy maintenance. Unlike poured concrete, which can crack over time, interlock patios are designed to flex with temperature changes and ground movement.

This guide will explore what an interlock patio is, its benefits, installation process, design ideas, maintenance tips, and cost considerations to help you decide if it's the right choice for your outdoor space.
