3. Drill and drill bits: A drill will be necessary to create holes along the basement wall for injecting the infill material. Make sure to choose the drill bit size based on the injection port diameter.
4. Caulking gun: If you are using epoxy resin, a caulk gun will be needed for the injection process. Make sure it is compatible with the epoxy resin cartridge.
5. Protective gear: Safety should always be a priority. Wear protective goggles, gloves, and a mask to protect yourself from any harmful fumes or debris.
6. Cleaners and sealants: You will need appropriate cleaners and sealants to prepare the injection holes and seal them afterwards.

Once you have gathered all the necessary materials, ensure that you have a clear understanding of the infilling process. Familiarize yourself with the instructions provided by the manufacturer of the infill material to ensure proper handling and application.

With all the materials prepared, you can now move on to Step 3: Drilling holes along the basement wall.

Step 3: Drilling holes along the basement wall

Now that you have your materials ready, it’s time to start drilling holes along the basement wall. This step is crucial as it allows for the injection of the infill material into the ground void. Here’s how to proceed:

1. Start by marking the location where you will drill the holes. It’s recommended to space the holes evenly along the affected area, typically around 12-18 inches apart.
2. Put on your protective gear, including goggles and gloves, to ensure your safety while drilling.
3. Choose a drill bit size that matches the diameter of the injection ports you will be using.
4. Position the drill at a slight downward angle towards the ground void and begin drilling. Take caution not to drill too close to the edge of the basement wall to avoid any structural damage.
5. Continue to drill holes along the wall, making sure to clean out any debris from each hole to allow for proper injection of the infill material.
6. Once all the holes are drilled, take time to inspect them and ensure they are clear of any obstructions or blockages. Use a brush or vacuum to remove any remaining debris or dust from the holes.

With the holes drilled, you are now ready for Step 4: Injecting the infill material.

When infilling ground void along a basement wall, use a flowable fill or lean concrete to fill the void and provide support to the wall. Ensure proper compaction to prevent future settlement.

Step 4: Injecting the infill material

Now that the holes are drilled, it’s time to inject the infill material into the ground void along the basement wall. The infill material, such as epoxy resin or polyurethane foam, will help fill the void and stabilize the soil. Here’s how to proceed:

1. Prepare the injection ports by inserting them into the drilled holes. Make sure they are secure and positioned correctly.
2. If you are using epoxy resin, load the cartridge into the caulk gun and cut the nozzle to the desired size. Follow the manufacturer’s instructions on mixing the epoxy resin, if required.
3. Start injecting the infill material into the ground void through each injection port. Apply steady and controlled pressure to ensure proper distribution of the material.
4. If you are using polyurethane foam, follow the manufacturer’s instructions on preparing the foam for injection. Use a foam gun or applicator to inject the foam into the void.
5. Continue injecting the infill material until it starts to come out of the adjacent holes or until you have filled the entire void.
6. Once the void is filled, remove the injection ports carefully. Clean off any excess material that may have squeezed out of the holes.

Take note of the curing time provided by the manufacturer for the infill material. Allow sufficient time for the material to fully cure and harden before proceeding to the next step.

With the infill material injected, it’s time to move on to Step 5: Sealing the drilled holes.

Step 5: Sealing the drilled holes

After injecting the infill material into the ground void, it’s important to seal the drilled holes to ensure a proper and finished appearance. Sealing the holes also helps to prevent any future moisture or air infiltration. Follow these steps to seal the drilled holes:

1. Start by cleaning the area around the drilled holes using a brush or damp cloth. Remove any dust, debris, or excess infill material.
2. Inspect each hole to ensure the surface is clean and dry before applying any sealant.
3. Choose an appropriate sealant compatible with the infill material used. Common options include epoxy-based sealants or polyurethane sealants.
4. Apply the sealant to each drilled hole, ensuring it completely covers the opening. Use a caulk gun or a putty knife to apply the sealant smoothly.
