Void Fill

Void Fill: Concrete settling is not the only issue that our foam can solve. Voids under slabs are often present in areas where wash out or excessive settling can occur. Our material will weigh on average 15-25 times less than a traditional mudjacking. This lightweight material will put less stress on an already failed sub-grade. The process of drilling, port installation, and injecting the material is the same as the raising process. All dual component polyurethane foams create heat when installed. Void fills must be done in a layering method to allow heat to dissipate safely.

Culvert & Pipe Fill

Filling abandoned culverts and pipes can prevent the danger of collapsing. FillFoam is strong, with the ability to absorb and store liquids remaining in the pipes, eliminating potential leaks. Liquids will not be capable of flowing through the pipe with foam in place. The foam in inert and resistant to any solvents or chemicals that could remain inline. In the event the pipes would need to be excavated, foam is lightweight and will prevent any fluids from leaking. Foam can also be removed to reopen the pipe for use again.

Custom installation systems can pump from 100 feet up to many miles while displacing fluids or debris that could remain in the pipes and prevent future leaks. Pumping distances will vary based on material density installed, pipe diameter, interior texture, slope, and contents.

Sinkhole Repair

Sinkholes can develop as rainwater is drained into the ground and it dissolves sediment and limestone. This creates voided areas underground. Sinkholes can also develop as water erodes sediment into bedrock cavities below. In some regions, one of the most common caused for sink holes is liquidification of soil during seismic activity. Otherwise solid soils behave as liquid with the stress applied while the ground moves. When these voids grow larger they can open up at the surface and cause dangerous cave-ins.

FillFoam can quickly and effectively fill these voids without heavy equipment. The FillFoam material will not wash away or interrupt the natural drainage.

Sinkholes are often filled from the opening. After the foam cures, topsoil is installed to relevel the area.

Riverbank Repair

Riverbanks are built to protect the shoreline from erosion. As waves crash onto the shore or behind the wall, water drains back into the river. As the water drains, soils are washed into the body of water. As more soils erode, large voids can develop that can lead to further damage to the riverbank the soils were supporting. Removal or repair of the riverbank is very costly.

FillFoam is a lightweight, strong and fast way to replace the eroded soils. It is important during a seawall repair that draining water not be blocked. If the drainage in interrupted or blocked, more problems can develop. Various FillFoam equipment options can offer solutions where heavy equipment and accessibility would otherwise be problematic.

Erosion Replacement

When drainage designs fail or systems are not in place, water often flows where it should not. This is common when water sheds off a building and flows under the slab of cement instead of over the slab. As water flows it washed away fill one particle at a time. Over time this creates washed out channels or voids under slabs or structures. If left unsupported, this lack of support will lead to settled concrete or structural failures.
