Instructions

Items Included in this Collection

Shop everything you need to build your own outdoor 43.5-inch round firepit with the Flagstone Firepit Kit Project Collection. This collection contains concrete retaining wall blocks to be used to form the fire pit and create a cozy spot for friends and family to gather. Use the interlocking pavers to frame the entertaining space. First, start with site preparation and excavation. Stake out the area where the retaining wall block will be. Dig a small trench, so half of the block fits in the ground. Next tamp the soil in the trench to create a ridged surface. Add 1” of sand to the bottom of the trench. Then, start leveling and laying stones. Lay stone side by side and check that they are level. Then, stack additional courses with the construction adhesive staggered on the course below. Finally, stack stones in courses, staggering the joints to the wall height.

Great product

Would Recommend

These are wonderful! I combined two colors together; one being more dominant than the other. The dual color added some depth and richness to the look. They fit together well and are easy to stack. Either side of the paver can be used. I mention that because another line of retention wall paver that I ordered only had one useable side. Highly recommend this product.

"Get Delivery" - Absolutely Horrible Experience

Would Not Recommend

Apparently Lowes has jumped on the "3rd Party" delivery bandwagon which unfortunately resulted in my worst experience ever as a regular Lowes customer. I expect the same customer service from the start of purchase to product in-hand and Lowes is forfeiting "last mile" responsibility and handing it to a company that does not care about the store, the product, or the customer. My order was late, the quantity was wrong and colors were incorrect. Had the delivery been handled by a Lowes associate ...
