Crawl Space Encapsulation & Waterproofing

Our team at Perma-Seal can help you fix your damp or wet crawl space. We offer professional crawl space waterproofing and encapsulation solutions in Chicago and NW Indiana.

Do you have a wet crawl space after heavy rain? Our team at Perma-Seal recommends sealing or encapsulating all crawl spaces. This upgrade helps protect your family and your home from excess moisture, toxic mold, unwanted pests, soil gases, and harmful airborne allergens.

With a Perma-Seal Crawl Space Encapsulation System, you can turn your dark, dingy crawl space into a bright, healthy, usable space. Waterproofing and encapsulating your crawl space is very different from waterproofing a basement, it involves using a heavy-duty liner (vapor barrier) as well as a specially designed drainage system and sump pump to remove the water from underneath your home.

How Do I Know If My Crawl Space Needs Waterproofing?

Several signs indicate a waterproofing and encapsulation system might be necessary in your crawl space. One obvious sign is standing water in your crawl space. If the crawl space has a dirt floor, wet soil may also indicate water intrusion. Keep an eye out for the following signs of crawl space issues:

  • Musty Odors
  • Mold and Mildew Growth
  • Sagging Floors and Floor Joists
  • Pests and Rodents
  • Standing Water
  • Poor Indoor Air Quality

What is Included in Crawl Space Encapsulation?

Our crawl space encapsulation and waterproofing process uses different systems depending on your home’s needs. These can include crawl space liner installation, crawl space waterproofing systems, dehumidification, and thermal insulation. Since every home’s needs may vary, our team can help walk you through the benefits of our various solutions.

Our Crawl Space Liner Systems

Crawl space liners, also called vapor barriers, help disperse soil gases and enhance water drainage below the floor liner. Our wall liners are 100% waterproof and will act as a barrier to moisture, gases, insects, and odors. They will not support mold growth.

We use four different crawl space liners depending on the needs of the crawl space: 

Soil Gas Dispersing Fabric

Soil Gas Fabric - Crawl Space Encapsulation Liner
  • 100% Polypropylene fibers that won’t rot or decay
  • Added cushion for the floor to protect liner, hands and knees

TerraBlock™

TerraBlock - Crawl Space Encapsulation Liner
  • 3/4″ flexible foam with vapor barrier on both sides
  • Adds a R4 insulation value to the floor
  • Much thicker cushion for the floor to protect liner, hands and knees

CleanSpace™ Liner

CleanSpace Liner - Crawl Space Encapsulation Liner
  • 20 mil thick, puncture resistant liner
  • 25 year warranty against punctures and tears
  • Will brighten your crawl space

SilverGlo™

SilverGlo crawl space insulation
  • Added R11 insulation value for exterior walls to reduce your heating and cooling costs
  • Radiant barrier also reflects heat back into your crawl space

Additional Crawl Space Solutions

Crawl space encapsulation will usually only solve one of the many problems homeowners have in their crawl spaces. We offer a variety of solutions and designs for crawl spaces in the Chicago area that can help you tackle other issues. Learn about our ventilation and waterproofing solutions for crawl spaces below. 

Crawl Space Waterproofing

Crawl Space Sump Pump System

You may not yet be experiencing standing water in the crawl space (or perhaps are unaware of it), but our crawl space drainage system, in conjunction with a crawl space sump pump and battery backup system, ensures that your crawl space will remain dry.

Soil Gas & Radon Ventilation

Crawl Space Soil Ventilation Pipe for Encapsulation

A passive ventilation pipe is installed during the encapsulation process to vent soil gases to the outside, preventing them from building up pressure under the liner. This system never needs maintenance because it has no moving parts.

Perma-Foam Rim Joist Insulation

Perma-Foam Rim Joist Spray Foam Insulation

Insulating the floor rim joist area in your basement or crawl space will make your upstairs living space more comfortable and increase energy efficiency. Perma-Foam will seal off unwanted drafts, deter pests, and resist mold and mildew.

Crawl Space Dehumidfication

PermaDry Humidity and Air Quality Control System for Basements and Crawl Spaces

High humidity in your crawl space is often the main cause of mold growth and musty odors. Our Perma-Dry system is a two-in-one dehumidifier and air purification system designed to optimize humidity levels in basements and crawl spaces. 

Are Crawl Space Encapsulation & Waterproofing The Same Thing?

The shortest answer is no. While you cannot fully waterproof a crawl space without an encapsulation system, you can encapsulate it without installing a waterproofing system. Crawl space encapsulation means more than just water protection. It is a great investment to protect the health and safety of your home. The benefits include:

  • Controls moisture
  • Improves indoor air quality
  • Lowers energy bills with added insulation
  • Prevents structural or water damage
  • Prevents mold growth
  • Reduces pest infestations
  • Creates a clean environment
