Foundation and Concrete solutions that work!
Since 2014, we have completed hundreds of commercial and residential projects. APD understands the foundation process from start to finish.
APD is well versed in underpinning, injection grout piers, chemical grout and poly foam injection. We create a solution according to your budget and property needs.
Our Polyurethane Division has completed hundreds of concrete projects, including Weeki Wachee Springs and The Florida Aquarium.
Types of Foundation Repairs
Underpinning
Underpinning is one of the more popular methods of Sinkhole Repair. The weight of your home is lifted on special piers known as “Underpins”. These underpins are inserted deep below the earth until they hit solid ground. This underpinning method strengthens an existing structure's foundation.
Underpinning may be accomplished by extending the foundation in depth or breadth so it either rests on a more supportive soil stratum or distributes its load across a greater area. This underpinning method is generally applied when the existing foundation is at a shallow depth, but works well up to fifty feet deep.
Grout Injection Piers
Grout Injected Piers are a combination of two different methods of sinkhole and foundation repair. Grout Injected Piers are large diameter, perforated, steel pins that are installed beneath your home until competent limestone, or solid bedrock is reached. Then grout is pumped in to seal off the limestone layer.
Compaction Grouting
This is the most common form of sinkhole repair. A low slump grout is used in areas with sinkhole conditions. It is injected into soils at or above the limestone layer to seal collapsed limestone, fill voids and compact loose soils. Grouting is the best method to repair homes that have loose soil.
Chemical Grouting
This grouting method is sometimes recommended by engineers to stabilize shallow soils around the perimeter and near the surface of your home following Compaction Grouting or Foundation Underpinning. The chemical will expand after being injected and firm up all loose soils that may be causing cracks and damage to your home.
How does deep foam injection work to correct foundation issues?
Poly foam injected into the ground stabilizes the subgrade by binding soils together. This both stabilizes and strengthens the subgrade beneath the residence or the concrete slab. Enough foam, with correct application, will lift slabs and structures.
Each project differs depending
-
on the objective of the project
-
the weight of the slab or structure
-
where the subgrade is unstable
-
which material is best to address the situation (see next column for more information)
An engineer is often required to determine the exact weight and load of a structure and why the subgrade has failed to support it.
We treat sinkholes and concrete problems with a Polyurethane Foam that is both 100% environmentally safe and 100% Hydrophobic (Hydro-Insensitive).
HF202
HF202 is a hydro-insensitive polyurethane foam specifically designed for jobs where water or moisture is present. This 2.5 lb. per cubic foot foam was designed to set up in the presence of water and to maintain dimensional stability in wet environments. HF202 is great for residential concrete and sinkhole applications.
HF202FAST
HF202FAST- Quick reaction times and low density make this foam great for lifting smaller lighter cement slabs. Not only is it hydro-insensitive, it maintains dimensional stability.
HF402
HF402 is another hydro-insensitive polyurethane foam specifically designed for jobs with water or moisture present. This 4 lb. per cubic foot foam was designed to set up in the presence of water and will maintain dimensional stability in wet environments. This versatile poly foam can be used for residential, commercial and/or industrial foundation and concrete applications.
HF402FAST
HF402FAST–The same strength as the HF 402, but with the speed of the HF 202 for less spread. Recommended for shallow deep foam injection sub-grade application, the faster reaction time makes it more suitable for lifting.
HYDROFOAM
HydroFoam was specially developed to resist hydrolysis, a chemical process in which water breaks down foam overtime causing the foam to shrink. Designed to not only set up in the presence of water, but to maintain dimensional stability, HMI’s hydro-insensitive foam holds up where other brands fail.
