How To Build An Addition Or Extension On A Concrete Driveway
I’m sure you’ve seen how many people are trying to fix their concrete driveways. It’s a hard job, but with the right tools and some patience, it can be done! In this post we’ll show you step by step instructions on how to build an addition or extension on your existing concrete driveway. Let’s get started, visit website.
- First, ensure your ground is firm enough for adding more weight by digging down about 12 inches (or 30cm) if necessary.
- Measure out where you want your new structure to go – Make sure that the dimensions of your planned addition/extension will not interfere with any other structures such as walls, buildings, trees or flower beds.
- Mix up batches of mortar in a wheelbarrow at least one foot deep and use it as needed while laying the extensions; make sure to thoroughly trowel out excess from between joints so they remain level with each other.
- Decide if you would like for the foundation to be a rectangular shape (planning ahead) or cut into an area already on your property. If desired, set up a string line and fence post in place now so they are ready when needed later on in the project.
- Dig down below the frost level about two feet deep and remove all vegetation from this hole; do not mix dirt with concrete because it’ll create air bubbles which may result in cracks during curing time! Fill the hole with gravel, then place a layer of concrete over the top.
- Allow to dry for at least three days before adding any weight onto it; this will give time for all moisture to escape and evaporate off from beneath your foundation. Add additional layers until you reach desired height (typically around 12 inches deep).
- Smooth out the edges so they are level using spacers or straight-edged boards cut into squares. Place a cement board on one side of your foundation by running a bead in between each course where the two meet up. Secure both sections together with screws if needed after overlaying another thin layer of adhesive and let that set overnight.
- Once dried, attach wall framing members as well as roof supports according to specifications given by local building codes . You will also need to attach the roof rafters, sub-framing and any other framing members that are not already attached.
Laying a concrete extension can be accomplished in just two or three days, as long as you plan for the work and have all necessary materials on hand. Once the ground is prepared—either by digging down to its original level if it’s been raised up or by adding additional cement layers (never more than one foot of thickness)—the next step is to mark out sections using straight lines between posts every eight feet (.25 meters).
You may add these yourself with stakes and string; try not to use anything too sharp so that they are easy to remove later if desired. Remember that length must always exceed width when laying an addition, due to compressive forces from weight being applied over time. For a more polished look, you may want to lay glass panels in between each post.
If it’s an addition being constructed next to a house, the walls will need to be reinforced with steel beams and posts before anything can happen further. After this is done, all portions of concrete must be prepared or cured properly first; then they are ready for use! Excavation and pouring the foundation should follow this step-by-step process: Dig down about one foot (.25 meters), line up rebar where needed (check your local building code), pour cement into formwork so that it’s level with ground height, cover flooring evenly using wood slats if desired. Smooth out surface by troweling off excess material using a large trowel.
