Fire pits are an essential for those who love to entertain, but their value and impact can be felt on a daily basis. They are able to be utilized year round, and give you a reason to spend time in your outdoor oasis that you’ve put so much time and effort into, even if that simply means unplugging after a long work day and unwinding by yourself or with family members.

WHY CHOOSE GRANITE OVER BRICK OR CONCRETE?

You may have seen or heard about alternative fire pit options. Brick and concrete are two other common materials considered for fire pits, but when investing in something that will get as much use as an outdoor fire pit, it’s important to choose the most reliable (and aesthetically pleasing) option. Unlike brick and concrete, granite is incredibly naturally durable and will stand up to the elements year after year. Able to withstand the freeze-thaw cycle, granite is a virtually maintenance free option, and won’t rust or stain your outdoor patio — it’s as tough as it is beautiful.

Swenson Granite Works’ DIY kit utilizes far fewer stones than its brick or concrete counterparts. Fewer stones means less time assembling, and less work for you. No mortar is used in the assembling of these kits — blocks are stacked and will stay together. Natural stone offers a variety of colors to choose from, and the colors you’ve so carefully selected will not fade.

A GUIDE TO FIRE PIT INSTALLATION

Not quite sure where to start? Building a fire pit is easier than you think. (Not to mention you get to tell your guests you did it yourself — no contractor required.) South Hadley, Massachusetts store manager Daniel Richard and assistant manager Thomas Gajewski will walk you through an easy to follow demonstration on how to install a Woodbury Gray granite fire pit kit.

These step-by step instructions will make assembling your fire pit easy and accurate.

  1. You will first need to excavate an area approximately 4’-6” in diameter and at least 6” in depth. Fill the area with processed gravel or mason sand, compacting until level. Then, dig a hole in the center of this circle approximately 12” in diameter and 24” deep and fill it with crushed stone. This will allow proper drainage during periods of rain. If you are building your fire pit on top of a solid surface, such as a patio with stone pavers, take out enough pavers in the middle of the circle to dig the required hole, then pitch the remainder of the pavers that are within the circle toward the hole for proper drainage.

  1. As Swenson’s granite fire pit blocks are a natural stone, there will be a variation in thickness, which is well within the standard industry guidelines for cut granite products. Take some time to sort through the blocks and make groups of sixteen blocks that match thickness as closely as possible, reserving the most consistent block layers for use as your middle and/or top layers. The reason for this is that the bottom layer is your most flexible layer, in that you can adjust the gravel to create a level surface with which to add additional layers.

  1. Using the metal ring as a guide, line up sixteen granite fire pit blocks around the ring, which will create a circle of granite with a 30” inside diameter. Adjust the fire pit blocks as needed to be sure they are tight together, and that they are level. Then, remove the metal fire ring.

  1. Install the second layer of fire pit blocks on top of the first layer, overlapping blocks as you go to form a solid bond. Install the metal fire ring into this second layer, to ensure that you have a good tight fit, or add a third layer of fire pit blocks before fitting the metal fire ring.

  1. The interior of the fire pit will need to be filled with processed gravel or mason sand. Compact the layers of gravel every four inches or so, until you reach the bottom of the flange of the metal fire ring, readjusting stones as needed to create a good fit.

  1. Complete your fire pit: Metal dome fire pit screens are available to purchase from Swenson Granite Works. The dome screen will offer an added layer of protection from the fire and prevent sparks from burning those sitting around it. However, if you want to partially expose the fire, the dome does open up.

  1. Light a fire and enjoy your quality fire pit from Swenson Granite Works!
