Crawl Space 2018-02-13T13:22:12+00:00

Insects and rodents thrive in dark, wet spaces such as the crawl space under your house. The moisture inherent in crawl spaces can allow dangerous mold and mildew to accumulate, as well as damage the structure or foundation of your home. The growth and damage can even decrease your property value.

Solution

Atlaro International & Co. can waterproof your crawl space using top rated products and proven techniques by which moisture is reduced and your family is better protected from mold and mildew. Our services are designed to offer you the best solution for waterproofing crawl spaces in your home.

  • Vapor barriers
  • Crawl space encapsulation
  • Crawl space waterproofing products
  • Repair foundation cracks
  • Drainage systems

Vapor barriers provide a physical barrier that prevents moisture within your crawl space from reaching the interior of your home. These vapor barriers protect your family from the build-up of mold and mildew by covering the ground of the crawl space.

Crawl Space Encapsulation

Encapsulation takes vapor barriers to the next level in order to fully protect your home.

Crawl Space Waterproofing Products

The same products used for waterproofing a basement may not be the proper product to use for waterproofing a crawl space. Each of our inspectors knows which waterproofing products are best suited for your moisture problems.

Repair Foundation Cracks

It is not uncommon for water to penetrate a crawl space through cracks in the foundation. We can identify and correct any problems with the foundation, including cracks in the mortar, brick, block or concrete.

Repair Structural Damage

Water is known to cause structural damage, especially if your home’s water problem is not addressed immediately. Structural damage can actually cause the value of your home to decrease dramatically.

Drainage Systems

Most crawl spaces are wet and require a drainage system underneath the crawl space encapsulation. Our specialist will recommend a drainage system that is best for your crawl space condition. A basement Sump Pump will be necessary in wet crawl spaces to drain the water and pump it out.

Step 1: Preparation

Correct any drainage issues. Install a sump system if needed. Make sure downspouts are directed away from the home and there is a proper grade. Repair large cracks or damaged walls. Clean up low hanging ductwork, pipes, wiring and insulation. Clean walls with soap and water in preparation for application of fabrication tape. Walls should be free of any debris and dry before installing fab tape. Remove any debris and sharp objects. Rake the floor as level as possible. Install foundation vent covers and dehumidify the space if needed. If you have combustion appliances in your crawl space such as a furnace or water heater, you should consult your HVAC professional prior to installing a crawl space vapor barrier system. Always install a carbon monoxide detector in areas with combustion appliances.

Step 2: Install the Wall Curtain

Apply fabrication tape at least 3″ below the top of the crawl space walls (snapping a chalk line can help you keep an even distance from the top of the wall). Apply fab tape on piers or support walls at least 18″ above floor. Install vapor barrier directly to fab tape and trim around any obstructions or openings. Pipe boots will be installed later for pipes up to 8″ diameter. Be sure to leave a gap at least 3″ from the top of the wall to allow for termite inspection. Pipe and other wall penetrations should be cut and patched using fab tape. Seam tape can be added as desired for cosmetics and patching.
Now is a good time to install mechanical fasteners. Using a ¼” masonry bit, drill a hole through the vapor barrier at the center of the fab tape and install an expansion fastener every 3 feet. Installing these now will avoid getting concrete dust on your vapor barrier floor as well as give you extra strength should you pull on the vapor barrier while covering the floor area. Wipe dust from wall curtain prior to installing floor liner.

Step 3: Cover the Floor Area

Install vapor barrier over the entire floor area allowing for a 12″ overlap for the wall curtain and all floor seams. Install vapor barrier on piers or support walls at least 18″ above floor. Trim around any obstructions or openings and patch with fab tape and seam tape if desired. Pipe boots can be installed on top of the barrier for pipes up to 8″ diameter. Remove debris and save tape and extra materials for repairs.
