Weak soils are very abundant in Florida! Some of these lands have been undisturbed for millions of years. Once development begins on some of these loose soils, structural failure is almost certainly inevitable. Upon building a structure, these soils begin to slowly compact against the weight of the structure and sometimes they need help in supporting the newly introduced loads to eliminate settlement.
The technology and methodology of building has changed dramatically over the last 10-15 years. Now, typically, soils are tested prior to construction to determine the density and composition in relation to the support characteristics needed for the proposed structure to be built. Prior to this time frame, testing was not accomplished and we can begin to see the stresses (cracks) in some structures from older construction.
In either case, new or old construction; there is a solution to stiffen and compact these soils:
1-part Polyurethane, Soil Stabilizer This product is injected directly into soft soils to provide a glue-like bond of weak or shifting soils. It can be injected to depths of up to 20 feet to provide a very secure base after construction or it can be applied prior to construction and has the capability of turning ordinary “ball-bearing” type contractor fill dirt into 1200+ p.s.i. bonded soil… like turning your soil into concrete. This product, carries the same longevity claims as polyurethane as well as being totally harmless to the environment. Soil Stabilizing can also be used for building water-tight soil curtains while excavating, provide a rock-hard bed for pipe-laying, or be topographically sprayed onto soils as a temporary (remember, sunlight will break it down) erosion control. 5-year Warranty against shrinkage.
