Filling Voids with Polyurethane Foam in Atlanta

There are many areas in which soil voids in and around structures may present a danger to the building and/or the people inhabiting the space.

Voids Caused by Soil Erosion

Sometimes these voids aren’t even noticed until damage has been done to the structure.  For example, a slab sinks after soil beneath it erodes away and forms a void.  Or a crack appears in a wall because the foundation is sinking due to voids in the soil that was once supporting it.  Pool decks can crack and large sections can sink due to voids appearing underneath.  This can cause a dangerous trip hazard for people using the pool.  Rocking slabs in a warehouse or factory floor can also be a sign of voids underneath. In all these cases, safety can be returned to the structures by filling the voids with high-strength polyurethane foam (and then lifting the slab or structure if needed).

Voids Caused by Other Factors

Soil erosion isn’t the only cause of voids that need to be filled with polyurethane. There have been cases in which floors have been in danger of collapsing due to design issues and the safest solution was to fill the crawl space void with polyurethane foam.  Sometimes contracters dig trash pits on new construction sites and fill them with debris left over from the building process.  Later on, the trash in the soil decomposes and voids appear.  Polyurethane void fill can also be an excellent solution for filling/stabilizing abandoned pipes.

Preventative Void Filling Can Save You Money!

You may even want to get your property checked by GCS for voids regardless of any danger signs.  We have advanced soil testing methods for just that purpose.  Filling voids BEFORE any damage occurs can save you a lot of money!
