Sealing the gap around your house foundation is vital in protecting your home from water damage. If you have a gap between your foundation and the soil, water can seep in and cause extensive damage to your home. In this blog post, we will discuss how to seal the gap around your house foundation.
Why do you need to seal your foundation gap?
Gaps around your house foundation can lead to several problems, such as:
-Water damage to your home’s structure: When water seeps into the gap around your foundation, it can cause the soil to erode. This can lead to the cracking and settling of your foundation, which can ultimately cause your home to collapse. In addition, water can also damage the interior of your home, including your walls, floors, and ceilings.
-Mold and mildew growth: Water that seeps into the gap around your foundation can create an environment that is conducive to mold and mildew growth. It can lead to health problems for you and your family and damage your home’s structure.
-Pest infestation: Gaps around your house foundation can provide an easy entry point for pests, such as rodents, insects, and snakes. These pests can not only damage your home’s structure, but they can also carry diseases that can be harmful to you and your family.
Types of Foundation Gaps
There are two main types of foundation gaps: vertical and horizontal.
Vertical gaps are the most common type of gap and are usually caused by settling your foundation. As your foundation settles, it can create a space between your foundation and the soil. This space can range in size from a few millimeters to several centimeters.
Horizontal gaps are less common but can be just as problematic as vertical gaps. Horizontal gaps are usually caused by poor drainage around your foundation. If water is not properly drained away from your foundation, it can pool around your foundation and create a gap.
How to seal the gap around your foundation
You can seal the gap around your foundation in a few different ways. The best way to seal the gap will depend on the size of the gap and the type of foundation you have.
Sealing the gap around your foundation is a three-step process: repairing the damage, sealing the gap and finishing up.
- Repairing the damage: The first step in sealing the gap around your foundation is to repair any damage caused by water seepage. It includes cracks in your foundation, settling of your foundation, and erosion of the soil around it. If you have extensive damage, you may need to consult with a professional to have your foundation repaired.
- Sealing the gap: Once you have repaired the damage, you can seal the gap with caulk, expanding foam, or a concrete patch. You can buy these sealants at your local hardware or home improvement store.
For small gaps, you can use caulk or expanding foam. Apply the material to the gap and allow it to dry for the amount of time specified by the manufacturer. This method is ideal for gaps that are less than ½ inch wide.
You may need to use a concrete patching compound for larger or more significant gaps. To use this method, apply the patching compound to the gap and allow it to dry. This method is best for gaps that are larger than ½ inch wide.
If you have a brick foundation, you may need to use mortar to seal the gap. Just apply the mortar to the gap and allow it to dry.
You may need to use grout to seal the gap if you have a stone foundation. To implement this method, apply the grout to the gap and allow it to dry.
- Finishing up: Once you have applied the sealant, you should smooth it out with your finger or a putty knife. You should also remove any excess sealant from your foundation or the surrounding area. Again, make sure you allow the sealant to dry for the amount of time specified by the manufacturer.
Sealing the gap around your foundation is essential in protecting your home from water damage. By sealing the gaps around your foundation, you can help prevent serious problems, such as water damage, mold growth, and pest infestation.
