A backyard BBQ pit is the ultimate symbol of summertime fun. With a custom-built pit, you can cook up tasty barbecue for family and friends. Building your own BBQ pit may seem daunting, but with the right materials and techniques, anyone can create an outdoor cooking space to be proud of. This comprehensive guide will take you through all the steps involved in constructing a stellar BBQ pit from scratch.
Planning Your BBQ Pit
The first step in any major DIY project is planning. Building a BBQ pit requires forethought so that your cooking station is functional, durable, and aesthetically pleasing. Here are some key considerations as you plan out your pit:
Decide on fuel type – Will you use charcoal, wood, gas, or a combination for fuel? This will impact the design.
Determine size and shape – Consider how much food you want to cook at one time and the footprint available in your yard. Rectangular and circular designs are common.
Pick a location – Choose a level spot away from overhead trees and shrubs. Ensure it is conveniently located near your home.
Consider materials – Brick and stone are classic, but metal, concrete and cinder blocks also work. Ensure adequate ventilation.
Add accessories – Include side tables, storage, lighting and prep space based on your grilling needs.
Check local codes – Many areas have laws about pit placement and safety requirements. Research before building.
Make a plan – Draw up your pit design with precise dimensions and building materials.
With an excellent plan in place, you can move on to the fun part – building your BBQ pit!
Choosing Materials for Your Pit Construction
The materials you select will determine how safe, durable and weather-resistant your BBQ pit will be over the long haul. Here are some top options to consider:
Brick
The quintessential material for building a classic BBQ pit is brick. Red brick has an attractive look and withstands high heat. Firebrick has even greater heat resistance. Stack bricks using steel rebar and mortar for solid stability.
Stone
Natural stone like granite, marble or limestone lends an elegant, rustic vibe and handles temperature extremes. But it is expensive and can be hard to install. Manufactured stone veneers offer an affordable alternative.
Concrete Blocks
Cinder blocks present a cost-effective option for DIYers. Their modular design speeds construction. Look for high-heat resistant concrete blocks specifically designed for ovens and fireplaces.
Metal
Stainless steel offers a sleek, contemporary look that conducts heat efficiently. But it can dent and scratches may rust. Aluminized steel is more economical. Metal inserts or chimneys help control airflow.
Refractory Cement
Applying this special high-temperature cement to the interior sidewalls offers superior heat resistance. It prevents cracking and crumbling common with other materials.
Selecting the right combo of materials for your BBQ pit is key to functionality and longevity. Talk to experts at your local home supply store for advice.
Setting the Pit Foundation
With materials secured, you can break ground on your BBQ pit. The first step is excavating and preparing the foundation. Here is how to do it right:
Clear and level the site – Eliminate vegetation and use a shovel, rake and level to create a flat base.
Dig a shallow trench – The trench perimeter should be 6-12 inches deep by 12-24 inches wide.
Fill with gravel – A 4-inch gravel layer promotes drainage and prevents sinking and shifting.
Install foundation blocks – Arrange concrete blocks around the trench to frame the pit foundation.
Pour concrete – Mix and pour concrete into the trench to form your solid pit floor. Let cure fully.
Construct a base – Stack rows of bricks or blocks to desired height to create your pit’s base.
Taking time to properly prepare the foundation will provide the stable support a BBQ pit needs. The base raises the pit up for convenient cooking access.
Building the BBQ Pit
With your pit foundation and base complete, the real construction can commence. Follow these tips to put together your pit:
Use fire-rated materials – Select solid, heat-resistant bricks, blocks or stones. Refractory cement boosts fire safety.
Apply binding agent – Mortar between bricks or metal brackets for other materials hold everything together.
Mind the gaps – Leave small gaps between materials for ventilation and heat dissipation.
Arrange for airflow – Strategic openings at firebox level and the smokestack circulate air.
Install thick walls – At least 6-inch thick walls retain heat and provide sturdy structure. Angle walls slightly outward.
Add an offset smokestack – Using metal ducting, position the smokestack slightly offset from the firebox to support air circulation.
Include a lid or door – A heavy metal lid traps in smoke and heat. Hinged doors allow easy fire access.
Insert cooking grates – Install commercial cooking grates at an optimal height above the firebox based on your usage.
Apply fireproof coatings – Seal the interior surfaces with high-heat resistant cement or epoxy for protection.
Taking it slow and steady as you construct the pit walls, smokestack, doors, grates and accessories results in a safe, well-functioning BBQ for years of grilling.
Accessorizing Your Backyard Pit
Beyond just the core pit structure, well-designed extras make your outdoor cooking experience complete. Consider incorporating any of these popular accessories:
- Side tables – Additional stainless steel fold-out tables let you prep food right at your pit. Include sturdy cabinets for storage underneath.
- Tool hooks – Install hooks along the pit exterior for hanging essential grilling tools within easy reach.
- Temperature gauge – A mounted thermometer on the lid makes it easy to monitor cooking temps.
- Rotisserie – A motorized rotisserie kit enables you to slow roast meats and poultry.
- Grill cover – A heavy-duty weatherproof cover protects your pit when not in use.
- Lighting – Install lighting right over your pit for grilling into the evening hours. Choose solar or electric.
- Sink – For serious grill masters, add a mini sink with hot water for cleanup duties.
- Shelving – Extra shelving provides space for platters, condiments and grilling accessories.
Take time to think through how you grill and what amenities would make the experience more functional and fun for your needs. Quality accessories show off your craftsmanship.
