Foundation Waterproofing Membrane - HDPE

Foundation Waterproofing Membrane - HDPE

Our heavy duty waterproof HDPE material is an ideal solution for limiting subterranean water movement. The HDPE sheet material is typically installed outside, adjacent to the building's foundation and acts as a reliable water barrier for basements and crawl spaces.

Water Membrane at a Glance

• Manufactured in the USA
• Built-In UV Stabilization
• Made with Recyclable Materials
• 100 year in-ground lifespan
• Joins vertically or horizontally with HDPE Sealant Tape
• Easy to cut with a standard utility knife

Attach to a Foundation Wall (Optional)

To adhere the HDPE water barrier membrane to a foundation wall consider utilizing the HDPE Vertical Lock Adhesive or alternatively the self-adhering SubSeal Water Barrier product line.

Installation

1. Dig a trench a few inches back from the building's foundation and where you plan to install the water barrier. At a minimum the trench should extend 1/2" above the surface. To install, dig the trench 1/2" less deep than the depth of the barrier that is to be installed. For example if you are installing a 30" barrier, dig a 29.5" trench. Ideally, allow the barrier to extend 2" above ground in order to prevent any surface water pooling on the surface from flowing over and behind the barrier.
2. Place the water barrier in the trench. If connecting two segments of barrier be sure to overlap the segments by 2 feet, use sealant tape vertically and horizontally to connect the seam. The taped overlap will prevent the ground water from flowing through the joint.

Shipping

We offer free ground shipping on all of our water barriers. Most orders ship same day if placed before 12:00 PM EST. Transit times are displayed in business days and are approximate.

Other Applications

HDPE water barrier can also be used as a root guard for trees, bamboo and weeds. When used as a root guard, the HDPE sheet effectively prevents the plant's root from spreading throughout the landscape.

The Many Uses and Applications of High-Density Polyethylene

High-Density Polyethylene, commonly known as HDPE, has become one of the most valuable and popular materials used by manufacturers for making their products as well as being recyclable. Recycled HDPE is just as good as virgin HDPE and is used for a huge range of products due to its strong internal structure and durability. Some of the recycled high-density polyethylene material is used for bottles, plastic tables, plastic lumber, pens, fences, furniture, benches, toys, rope, trash cans, recycling bins, decking, and bike racks — and that is just the tip of the iceberg.

Because it is made from petroleum, HDPE is a polyethylene thermoplastic. It is one of the most flexible plastic polymers on the planet and is a chosen plastic used in manufacturing. It is considered one of the best plastics available on the market — not only the most popular material to date, but also one of the most popular recycled materials.

Because of its strong internal structure, HDPE runs a very low risk of leaching into foods and beverages enclosed within the material. According to the FDA, HDPE is rated as a food-safe plastic. High-density polyethylene is a Type 2 plastic, symbolized on the bottom of containers with a triangle formed by arrows and the number 2 in the center. HDPE products are also eco-friendly in comparison to other consumer plastics. One key benefit: high-density polyethylene does not contain allergens, heavy metals, or phthalates, and it will not release harmful fumes into the environment.

HDPE Uses in the Industrial Field

HDPE leads the pack in protecting the environment through the use of recycled materials. The most popular industrial uses include:

• Pallets
• Storage box containers
• Utility pipes
• IBC containers

Advantages of HDPE and Recycled HDPE

High-density polyethylene can be recycled many times over before it is no longer useful. It is a non-biodegradable plastic, which means it can take an extremely long time to decompose if simply thrown into a landfill after use — but when recycled, HDPE offers many advantages for the environment and for manufacturing. Research has shown it is less expensive to manufacture products using recycled HDPE than to create something from scratch using new plastic. Both recycled and new materials are extremely long-lasting.
