Crawl Space Waterproofing Guide to Stop Leaks and Improve Efficiency

Posted on: 9 July 2020


The crawl space of your home is an area where a lot of problems can start. You want to make sure that you have good waterproofing and drainage. In addition to the waterproofing systems, some improvements can improve energy efficiency and protect your home from damage. The following crawl space waterproofing guide will help you stop leaks and improve your home:

Repairing and Updating Old Waterproofing

Outdated waterproofing is the first area where your crawl space may need improvements. Today, there are modern waterproofing sealants and membrane systems that can be combined. These materials help keep the water out, as well as protect against damage. The membrane systems will help stop the static water pressure that causes foundations to crack and waterproofing to fail.

Installing the Right Drainage and Sump Pump If Needed

Drainage and sump pumps are also important in your crawl space. These are an important component of a complete foundation waterproofing system. The sealant helps keep water out of the foundation, and the drainage directs runoff away. In some foundations, the waterproofing drainage may need and additional sump pump. The pump is what is used to remove any water that can get into your foundation.

Making Sure Your Crawl Space Has Good Cross Ventilation

The ventilation in the crawl space is important and prevents moisture problems. Cross ventilation is critical in a foundation because it allows the moisture that causes problems like mold and rot to escape. When you have the waterproofing done, ask the contractor about ventilation and adding vents to help protect against these problems.  There should be plenty of vents that are adjacent to allow air to flow through the foundation and carry moisture out.

Encapsulation to Seal the Crawl Space

Another option that you may want to consider for your home is crawl space encapsulation. This is a great addition to waterproofing, which will completely seal the interior of the foundation. Encapsulation is also a great way to stop energy loss due to air leaks.  The process of encapsulation involves sealing the dirt or gravel floor of the foundation, as well as the floor system and foundation walls. Once the encapsulation is complete, outside air or moisture cannot get into your home.

These are the things that can be done to stop leaks and improve your home with crawl space waterproofing. When you are ready for these crawl space improvements, contact a crawl space waterproofing service for help.
