When excavation begins, topsoil is stockpiled to resurface and provide nutrient rich soil for grass seed to take root in.
Clearing and Grubbing
Stabilized sand is used to fill the excavated hole and is compacted gradually to ensure that the sinkhole does not form with normal rainfall.
PSL provides affordable land clearing services using methods that reduce unwanted lingering root material and excess construction stormwater pollution.
Slope Repairs and Stabilization
Our staff has an in depth knowledge of not only the causes of sinkholes and slope failures, but the proper methods to fix them. Below is a series of pictures before during and after the formation of a sinkhole repaired by PSL.
All sediment must be excavated past the location of the failure and any water seams found in the substrate. Excavation is completed when all soil surrounding the sinkhole is compacted and stable.
Above is a 3 foot wide sinkhole in the middle of an access easement that formed as a result of natural sediment compaction as pre-development root material decomposes beneath the surface. These sinkholes can be dangerous as they are known to grow rather quickly and unexpectedly.
