Patented Design

Chamber systems are easy to install. Engineered for strength and performance, they have greater design flexibility including a smaller footprint as compared with stone and pipe, and are made from recycled materials. These advantages of Infiltrator chambers add up to cost savings on labor, materials and time savings on the job. Look below to see all of the benefits of chamber systems.

Ease of Installation

Chamber System Installation Infiltrator chambers can be delivered to the site in a pickup truck and hand-carried into position. For most jobs, two people can install a system in less than half the time it takes for a comparable stone and pipe leachfield.

Cost Savings

No stone or geotextile is typically required, and chamber installations use less pipe. Installations are faster so you save on heavy equipment operation and eliminate the need for heavy trucks used to transport stone.

Engineered for Optimal Performance

Chemical-resistant and UV-stable

Powerful arch design supports loads of 16,000 lbs, with 12 inches of compacted cover (equivalent to an AASHTO rating of H-10).

Chambers can be installed with 6 inches of cover to support axle loads of 4,000 lbs.

All products carry a limited warranty and are certified to the International Association of Plumbing and Mechanical Officials (IAPMO) structural testing protocol.

Less Site Disruption

Since Infiltrator chambers typically occupy a smaller total area than stone and pipe leachfields, and use less heavy equipment, there is less damage to property and landscaping. Elimination of stone means easier cleanup at the job site.

Superior Technology

A solid top prevents infiltration of rainwater and the intrusion of fines
Sidewall louvers allow lateral leaching and evapotransporation
An inspection port cutout permits monitoring and maintenance
Patented chamber interlocks with an advanced design connect chambers end-to-end with a precise fit
Advanced contouring connections allow chambers to avoid obstacles
Open bottom provides unobstructed soil interface, allowing up to 50% reduction in trench length
Longevity and Reliability

Infiltrator chambers demonstrate a higher success rate, which is far better than stone and pipe, giving homeowners and installers extra confidence.
