When large, concrete-floored buildings like warehouses are built, the concrete is poured into many smaller slabs. When the building is new, these slabs generally lay evenly and the joints between then are not easily noticed. Over time, however, wear and tear on the floor, the weight of trucks and fork lifts moving over the floor, and natural shifting in the soil causes the joints to buckle.

Soil erosion under buildings with slab foundations presents a major structural challenge. Such was the case at the Seneca Rocks Discovery Center, a rock climbing destination in West Virginia. Soil was eroding away from beneath the building's foundation, leading to tripping hazards as the floor buckled. There were basically two options for dealing with this: replace the floor or repair it.

Even when planned and designed properly, buildings can shift and sink over time as the soil beneath then erodes. This can be quite a costly problem for the owners. If left unaddressed, it can spell the end for a structure within a few short years. Fortunately, there is a way to stop the erosion and stabilize the soil beneath the building to prevent further shifting.

It's a common problem on roads and highways throughout North America -- the soil under a highway erodes, leading to uneven surfaces that present a driving hazard. This problem is hard to fix because it involves repairing eroded soil beneath large slabs of concrete. The traditional method has been to add more support to the road through mudjacking, but this method presents several big challenges. Recently, the use of TerraThane, a geotechnical polyurethane foam system, has become more common because it circumvents the challenges of mudjacking.
