How to Build a Durable and Eye-Catching Cinder Block Patio

A cinder block patio adds a touch of classic beauty and timeless appeal to any outdoor space. Crafting a cinder block patio is an accessible DIY project that can be completed with some planning, patience, and attention to detail. Here's a comprehensive guide to help you build a sturdy and visually pleasing cinder block patio.

Planning and Materials

Before embarking on this project, thoughtfully consider the size, shape, and location of your desired patio. Determine the number of cinder blocks and other necessary materials, such as sand, gravel, and mortar. Gather the following tools: a level, string line, shovel, trowel, and safety glasses.

Site Preparation and Excavation

Choose a well-drained area for your patio and mark the perimeter with a string line. Excavate the area to a depth of 8-10 inches, ensuring a level surface. Compact the soil firmly using a tamper or heavy object.

Laying the Base

Spread a 2-inch layer of gravel over the excavated area and compact it. Top with a 1-inch layer of sand and level it with a screed. This base will provide drainage and stability for the cinder blocks.

Setting the Cinder Blocks

Start by laying out the first row of cinder blocks around the perimeter, ensuring they are level and firmly seated in the sand. Fill any gaps with mortar. Continue laying subsequent rows, staggering the joints in a running bond pattern for added strength. Fill the cores of the cinder blocks with mortar as you proceed to prevent grass and weeds from growing.

Finishing Touches

Once all the cinder blocks are in place, let the mortar cure for 24 hours. Apply mortar to the surface of the patio and smooth it out with a trowel. Create a consistent slope of 1/8 inch per foot away from the house to facilitate drainage. Seal the patio with a clear sealer to protect it from water and UV damage.

Edging and Landscaping

Consider adding edging around the perimeter of the patio to enhance its appearance and prevent soil erosion. You can use plastic edging, metal edging, or decorative stones. Plant flowers or shrubs around the patio to soften the edges and create a welcoming outdoor space.

Maintenance

To keep your cinder block patio looking its best, maintain it regularly. Sweep or hose it down to remove dirt and debris. Inspect the mortar joints annually and reapply mortar as needed. With proper care, your cinder block patio will offer years of enjoyment.
