From gathering materials to understanding expansion joints requirements, this article will walk you through each step of the process so that you can successfully complete this project with confidence. 

To pour concrete against a house successfully you should gather the right materials, prepare and excavate thoroughly, plan, measure and secure a moisture barrier.

We have an ultimate guide on how to do this properly. 

Using A Professional 

If you are considering pouring concrete against your house, it is best to hire a professional for the job.

Professionals are knowledgeable about the best materials to use, the proper way to lay the concrete, and how to ensure the job is done correctly. 

They can also provide advice on the best way to maintain the concrete once it is in place.

Professionals also have the right equipment and safety gear, so you can be sure the job is done safely and correctly.

However, if you consider yourself a seasoned DIYer, then follow the tips below to get you on the right track. 

Gathering Supplies And Materials

Gathering the right supplies and materials for your project is an important step in ensuring that you get the results you want.

We tried doing it with old supplies we had around the house – let’s just say it didn’t end well! 

These include:

  • Concrete mix.
  • Rebar.
  • Wire mesh.
  • Stakes and string to mark out the area.
  • Forms for the slab or wall.
  • Shovels, hoes, and other tools for mixing and moving the concrete. 

You may also need some plastic sheeting to cover up any exposed dirt or grass and protect it from getting mixed into your concrete. 

Finally, make sure that you have enough water on hand to mix your concrete properly. 

Tips For Choosing Quality Supplies And Materials

Choosing quality supplies and materials for your concrete project is essential to ensure that you get the results you want.

There are a few tips to keep in mind when selecting all of your items.

First, only buy products from trusted manufacturers with a good reputation for quality.

Second, make sure that you can use all your items specifically for use with concrete and can handle the weight and durability requirements.

Third, read reviews and ask around for people’s opinions on different brands or types of products before making a purchase.

Finally, look for any certifications or seals of approval on the packaging to be sure that what you’re buying is appropriate and approved by industry experts.

Understanding Expansion Joints Requirements

Expansion joints allow for movement in the concrete due to temperature changes or other factors, which helps prevent cracking or warping.

When choosing expansion joints for your project, it’s important to consider the size and shape of the space you’re pouring into, as well as its expected temperature range.

Additionally, make sure you choose a material that is strong enough to handle the weight and pressure of your concrete mix.

Before installing, be sure to measure carefully and confirm that all pieces fit properly together before beginning.

Preparing The Site For Installation

It’s essential to make sure the job site is properly prepared for installation.

This includes ensuring that the area is level, free from obstructions, and clear of any existing vegetation or debris.

You should also make sure the area is free from standing water and that there are no obstructions in place that could interfere with the installation.

Additionally, you may need to create a perimeter of levels around the area where you plan to pour the concrete so that it can be properly measured and assessed before installation begins. 

Planning The Layout 

Start by measuring the area you want to pour the concrete in, including any obstructions like trees or landscaping features.

Once you have measurements, draw out a rough plan on paper that includes these details.

This will give you an idea of where any cuts, curves, or other shapes you may need to make when pouring the slab.

When it comes time for installation, make sure that your contractor (if you’re using one) has this plan, so they can properly install the concrete according to your desired specifications.

Excavating And Leveling The Ground As Needed

Excavating and leveling the ground is a necessary step before pouring concrete against your house.

You can use a shovel, rake, or other tools to excavate the area in order to achieve the desired depth.

Once you’ve done this, you’ll need to level out the ground by adding or removing dirt as needed in order to create an even surface.

This process can be time-consuming, but it’s essential for making sure that you pour your concrete properly and securely against your house. 

Securing A Moisture Barrier

Securing a moisture barrier is a vital part of the process, as this barrier prevents moisture from entering the concrete and causing damage over time.

The most common way to secure a moisture barrier is to use a polyethylene sheeting that is about 10-15 mil thick that’s designed for this purpose.

Make sure you cover the entire area where your concrete will be poured, including any areas near windows or doors, as these are vulnerable points of entry for water.

Once you have the sheeting in place, use stakes to fasten it securely to the ground so that it won’t shift during installation of your concrete. 


Installing concrete against your house can be a tricky process, but if you take the time to properly prepare the area and secure all necessary materials, it should go smoothly. 

Make sure to measure your area before you begin and plan out any cuts or curves you need to make. 

Additionally, don’t forget to excavate and level the ground as needed and secure a moisture barrier for added protection.
