How To Cover Exterior Basement Walls With Plastic Sheeting?

This article provides a step-by-step guide on how to attach plastic sheeting to exterior basement walls, aiming to transform the space into a dry and energy-efficient one. The process involves tying a 1-foot by 1-foot square of plastic sheeting to the concrete wall in the basement with duct tape and leaving it in place for 24 hours. If condensation is present inside the plastic, there’s a moisture problem.

Using construction adhesive, flashing, and tape, secure a 6-mil vapor barrier to a concrete wall to prevent moisture and mold problems. Dimple mats, semi-rigid plastic sheets with dimples, can help prevent basement moisture problems by creating a free-draining air space between the wall and the mat.

The article also discusses the impact of plastic vapor barriers on moisture and drying in different wall assemblies and climates. Interior vapor barriers are not recommended for hot humid weather and exterior vapor.

The guide covers framing, insulate, and finish a basement, covering dampness, obstructions, soffits, and more. For joists, spray foam all openings to the outside world, 2 inch 15PSI xps (can use polyiso), and spray foam all edges.

There are 15 types of wall panels for basement finishing, including waterproof, insulated, and decorative options. Building codes usually require a vapor barrier (4 mil plastic sheeting) on exterior basement walls if framing is attached to masonry or concrete surfaces.

In addition to installing a plastic vapor barrier, insulation can be installed using unfaced batt insulation with a 6 mil plastic vapor barrier towards the room. No plastic is needed, and a neighbor suggested installing thick plastic sheet/foil from the foundation wall going out 10ft and glueing it water.

How to attach a vapor barrier to a basement wall?

Polyurethane sheeting is a common vapor barrier utilized by contractors to prevent moisture from penetrating basement walls. It is stapled to the frame before plaster or drywall is applied.

Should you put plastic over insulation on exterior walls?

Building codes mandate the use of vapor barriers with insulation to improve indoor environmental quality and energy efficiency. Building scientists recommend this method, as it protects against diffusion. Polyguard recommends a quality air barrier system to limit infiltration, exfiltration, and moisture accumulation in the building envelope. Contact Polyguard professionals for more information on when to use a vapor barrier with insulation.

How do you cover outside basement walls?

This article explores various ways to cover exposed house foundations, including bricks, cement blocks, conceal and paint, flower beds, gravel, high bush and hedges, river rocks, and steel sheets. House foundations are crucial for maintaining a home’s strength and durability, as they serve as protection during harsh weather conditions. However, not everyone is fond of having exposed foundations as they can be an eyesore.

Some ideas include creating a lattice with bricks, using cement blocks, concealing and painting, flower beds, gravel, high bush and hedges, river rocks, and steel sheets. By considering these options, homeowners can protect their homes from deterioration and moisture intrusion, ensuring their structural integrity.

Should you put plastic on basement walls?

Excess humidity and moisture in basements can lead to mold growth and other issues. Installing a vapor barrier can help reduce damage by preventing water vapor from entering and maintaining a consistent temperature. If you plan to convert your basement into a living area, consider using a vapor barrier. Symptoms of moisture issues in your basement include a musty smell, visible mold and mildew stains, dampness, and visible water on the floor. These signs can indicate moisture issues and should be addressed promptly.

How do you attach plastic sheeting to concrete?

2-Sided Butyl Tape is a material used to adhere plastic sheeting to porous surfaces like concrete in crawl spaces or seam overlapping panels. It is best applied when the surfaces are warm or at least 45°F or more, and may require external heat when installed at lower temperatures. It is commonly used in agriculture, builds, ceiling covers, crawl space vapor barriers, gas mitigation barriers, green roof membranes, ground covers, grows, in-wall vapor barriers, landscape and hardscape, liners and covers, radon mitigation barriers, roofing vapor barriers, root barriers, silage tarps, underslab vapor barriers, and weed barriers.

How to waterproof foundation walls from outside?

To waterproof house foundations from the outside, follow these steps:

1. Excavate the soil around the perimeter of your foundation.
2. Clean and prepare your foundation walls.
3. Fix damage to your foundation walls.
4. Apply a waterproofing membrane to the outside of the foundation.
5. Install window wells.

There are various reasons to waterproof house foundations from the outside, such as protecting a finished basement from water intrusion without demoing it, or purchasing an old home with fieldstone foundation or cinderblock. The first step is to excavate the soil around your foundation walls, which can be done in sections or all at once.

For exterior waterproofing, it is crucial to expose your foundation wall all the way down to the base of the footing.

Can I cover basement insulation with plastic?

Insulation and vapor barrier plastic are often interconnected, but combining them can cause moisture issues and health risks. Exposure to insulation can lead to fire hazards, especially in warehouses or commercial buildings. Covering insulation with the right vapor barrier creates a safer environment for workers or residents. Americover’s Customer Success Manager, Daniel Mergens, advises contractors to consider building safety codes when choosing a cover. They offer a collection of insulation covers and can be contacted via phone or chat.

How to cover basement walls cheaply?

In summary, there are various affordable basement wall panels available to enhance the aesthetic appeal and functionality of your basement. These panels can be made from various materials such as brick, stone, wood, rigid foam sheets, decorative panels, flat panels, board and batten, drywall, and wahoo walls. These panels should not only match your style but also withstand moisture-prone areas. Choosing the right panel for your basement is crucial, as it should complement your decor and be easy on your wallet. By incorporating these inexpensive options, you can make your basement more family-friendly and stylish, making it a more enjoyable and cost-effective way to decorate your living space.

What to put on outside basement walls?

Groundwater issues can be addressed by exposing the exterior foundation and applying a waterproofing membrane. Rubberized asphalt membranes are effective but expensive due to excavation and backfilling. Interior waterproofing methods are affordable for mild to moderate water problems but still allow water to penetrate foundation walls. Large foundation cracks and major issues require waterproofing the exterior walls and addressing the root cause. A step-by-step guide on how to execute an exterior waterproofing project is provided.

How do you insulate exterior walls from the outside?

Blown-in cellulose is a method of installing insulation from the exterior of a building. It involves the removal of the exterior siding, the drilling of holes into the sheathing, and the blowing-in of the cellulose. This method does not necessitate the dismantling of the building, but it does have the potential to disperse dust through vents and outlets. Furthermore, it is susceptible to shifts and settlements over time, which may result in gaps devoid of insulation.

How do you secure a vapor barrier to the wall?

To install a vapor barrier in a crawl space, lay it flat on the floor and secure it to vertical surfaces using staple gun or adhesive. Overlap seams and use adhesive or tape to secure them. Seal edges and penetrations to prevent moisture seeping through pipes, vents, and other openings. Use adhesive or tape to seal gaps around pipes and vents. Inspect and test the barrier for loose or unsecured sections after installation and monitor the crawl space for moisture signs over the next few weeks.
