Spray foam trench provides solid, durable support.
Before backfilling the trench, PolyLevel® trench breakers, or water stops, should be installed, as it controls excessive amounts of water from flowing through the porous soil material and compromising the stability of the pipeline.
These breakers also prevent erosion and soil wash-out. This is valuable when protecting native soils and sediment that would otherwise be washed out by the trench.

Spray Polyurethane Foam (SPF) is an amazing material with applications across numerous industries, including pipeline installation.
SPF can be especially useful when working on pipeline trenches in rocky, uneven, or steeply inclined terrain. Some sort of pipeline trench support is required when dealing with these conditions.
Sandbags have traditionally been used to construct trench breakers, but our spray foam crew can do this work faster, more affordably, and with superior results.
The 2-part foam used in geotechnical applications has unique characteristics that provide important advantages in trench breaker construction. When the SPF resin and catalyst compounds are mixed at the application nozzle, the resulting chemical reaction turns the liquids into expanding foam with excellent adhesive qualities. The foam penetrates into loose soil and bonds to the sides of the trench excavation.
The foam expands, hardens and cures within minutes, making it possible to complete each trench breaker in a fraction of the time that a larger crew would require to build with sandbags. The cured SPF support is inert, environmentally safe, and immune to moisture damage.
Our SPF system is compact and portable, we don't need heavy equipment to transport tons of sandbags. SPF has what it takes to keep your project moving.
