The foam is injected via hose fed gun that supplies a measured amount of air, resin and catalyst that makes foam when combined together. The foam is white in color and resembles shaving cream in appearance.  [![1-888-301-1050](https://no-cache.hubspot.com/cta/default/28573/07e5c4ac-0322-4693-ac8c-208a9750db74.png)](https://cta-redirect.hubspot.com/cta/redirect/28573/07e5c4ac-0322-4693-ac8c-208a9750db74) **Tank Foam filling offers a number of financial advantages including:** - Lower excavation cost and dump truck and trailer are not needed to remove a tank from the ground and transport the tank to a recycling facility. - Surface restoration costs are not needed. A 1000-gallon UST measures 48” by 10’9”, the hole you dig to remove this size tank is larger both in width and in length.    The larger the excavation the more restoration that is required. Many tanks can be filled via the tank fill pipe or if excavation is necessary, you would have to excavate on average a 4’ by 4’ square holes to uncover a portion of the tank for cleaning and for equipment top access the tank void for foam filling. - If hardscaping is present over the tank including concrete, asphalt or pavers, the disruption with foam tank filling can be minimized, this reducing surface hardscape restoration. - Foam can be cheaper than concrete and is cheaper to remove if the tank is required to be removed at a future date in time. - Injected tank foam is non-flammable and chemically inert. The foam will note promote corrosion of steel tanks or react with residual petroleum products.   ![Curren Foam Trailer](https://www.currenenvironmental.com/hs-fs/hubfs/Curren%20Foam%20Trailer.jpeg?width=4032&height=3024&name=Curren%20Foam%20Trailer.jpeg) ![Can you foam fill a tank?](https://www.currenenvironmental.com/hs-fs/hubfs/Foam%20filling.jpg?width=500&height=375&name=Foam%20filling.jpg)   Pro Tip   To close any tank with foam the tank must be entered and cleaned of residual product, so some excavation is ALWAY required.   When you remove or close in place any buried petroleum storage tank, you must supply a clean inert material to fill the void space of the tank.   Installing foam into an emptied underground storage tank is the most cost-effective solution for legally approved abandonment of underground storage tanks (USTs), WHEN REMOVAL IS NOT PRACTICAL OR PROHIBITIVELY EXPENSIVE.   The tank in the photo below would be a candidate for foaming in place.    ![2023-05-19 11.58.27](https://www.currenenvironmental.com/hs-fs/hubfs/2023-05-19%2011.58.27.jpg?width=4032&height=3024&name=2023-05-19%2011.58.27.jpg)     Foam is also a cost-effective solution for filling the void space prior to the abandonment of buried vessels, including oil tanks, underground propane tanks, gas tank, rail cars and other large containers.   ![IMG_0922-1](https://www.currenenvironmental.com/hs-fs/hubfs/IMG_0922-1.jpg?width=3264&height=2448&name=IMG_0922-1.jpg)   # Can I foam fill a tank? Federal and industry protocols for tank closure in place allow a tank to be filled with an inert material.  An inert material can be fill, slurry, concrete or foam.   The advantage of foam is it is injected in a tank via a small diameter hose that can be snaked to hard-to-reach areas.   If in the future the tank must be removed foam is also easy to remove.   ## Call the Experts ## 888-301-1050   ![Foam filling tanks](https://www.currenenvironmental.com/hs-fs/hubfs/IMG_4209-1.jpg?width=4032&height=3024&name=IMG_4209-1.jpg)       ### Contact Curren [![Share on Facebook](https://static.hubspot.com/final/img/common/icons/social/facebook-24x24.png)](http://www.facebook.com/share.php?u=https%3A%2F%2Fwww.currenenvironmental.com%2Ffoam-filling-buried-storage-tanks%3Futm_medium%3Dsocial%26utm_source%3Dfacebook) [![Share on LinkedIn](https://static.hubspot.com/final/img/common/icons/social/linkedin-24x24.png)](http://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fwww.currenenvironmental.com%2Ffoam-filling-buried-storage-tanks%3Futm_medium%3Dsocial%26utm_source%3Dlinkedin) [![Share on Twitter](https://static.hubspot.com/final/img/common/icons/social/twitter-24x24.png)](https://twitter.com/intent/tweet?original_referer=https%3A%2F%2Fwww.currenenvironmental.com%2Ffoam-filling-buried-storage-tanks%3Futm_medium%3Dsocial%26utm_source%3Dtwitter&url=https%3A%2F%2Fwww.currenenvironmental.com%2Ffoam-filling-buried-storage-tanks%3Futm_medium%3Dsocial%26utm_source%3Dtwitter&source=tweetbutton&text=Foam%20Filling%20Storage%20Tanks) [![Share on Pinterest](https://static.hubspot.com/final/img/common/icons/social/pinterest-24x24.png)](http://pinterest.com/pin/create/button/?url=https%3A%2F%2Fwww.currenenvironmental.com%2Ffoam-filling-buried-storage-tanks%3Futm_medium%3Dsocial%26utm_source%3Dpinterest&media=) [LSRP ](https://www.currenenvironmental.com/njdep-lsrp-licensed-site-remediation-professional/)| [ISRA ](https://www.currenenvironmental.com/NJDEP-ISRA-Industrial-Site-Recovery-Act-Process-/)| [Services](https://www.currenenvironmental.com/services/remediation/remediation-overview/) | [Tanks](https://www.currenenvironmental.com/services/ust-removal/commercial-tank-removal/) | [Remediation](https://www.currenenvironmental.com/services/remediation/remediation-overview/) | [Real Estate](https://www.currenenvironmental.com/Environmental-Issues-in-Residential-Real-Estate) | [Mold Remediation ](https://www.currenenvironmental.com/mold-remediation--/)| [Blog](https://www.currenenvironmental.com/blog/) | [Contact](https://www.currenenvironmental.com/contact-us/) | [Foam Tank Filling](https://www.currenenvironmental.com/foam-tank-filling) | [Insurance Restoration](https://www.currenenvironmental.com/insurance-restoration/) |[UST AST Closure](https://www.currenenvironmental.com/ust-ast-closure/) Curren Environmental is your environmental services company servicing Delaware, New Jersey and Pennsylvania. *Nothing on this web page, or anywhere on this website, is to be construed as giving legal advice, nor is it intended to replace the counsel of your own legal and financial advisors.   The information supplied is intended to help make you more aware of issues that you should consider and then discuss with your own legal and financial advisors. * [*Privacy Policy.*](https://www.currenenvironmental.com/curren-environmental-privacy-policy) © 2026 Curren Environmental, Inc. - All Rights Reserved.
