Soil Stabilization

Severe changes in weather can affect soil conditions that can in return weaken the structure built upon it. Compromised soils need to be strengthened and secured in order to protect worksites, infrastructure systems, surrounding buildings and other structures built on top. Known as permeation grout, this process works like a glue when mixed with the existing substrate already in the ground producing long-lasting results and strengthening soil load capacity, or soil density. We can densify soils by injecting foam that expands and compacts its surrounding soils or by injecting a permeation foam that mixes and hardens the existing in place.


Our uniquely designed formulas allow for a variety of void fill applications. In the case of tank abandonment, Poly Foam can be utilized to re-establish load bearing capacity without excavation and removal of the existing tanks underground. Along with tank abandonment, Poly Foam can be utilized for void filling and safely abandoning other infrastructure systems including defunct pipes, manholes, culverts and tunnels. Proper abandonment of underground infrastructure can help deter future problems, like sinkholes, system failure and damage to surrounding buildings, roads and sewer systems.

Sink Hole
Tank Abandonment

Sinkhole voids occurring close to or underneath buildings and systems pose a high risk of causing foundation failure to surrounding structures. The expansive properties of Poly Foam allow for not only filling sinkholes efficiently, but also effective as it stabilizes loose soils while also filling small pores and crevices.

Void Fill


Requiring minimal to no excavation, void filling with Poly Foam is a fast & long-lasting solution. Because Poly Foam is flexible in that it expands to mold to almost any shape while also hardening to provide the needed strength to support above and surrounding structures and systems. It does this by creating a densified and compacted layer of soil.
