EagleLIFT’s concrete structure lifting technique
Simple to manufacture, versatile and tough, concrete is a widely used construction material. Standard concrete slabs typically weigh 150 pounds per square foot, while high-density ones can be twice as heavy. Loads this substantial and other environmental factors can strain base soils enough that they begin to compress, which is detrimental to any structure’s viability.
While traditional sunken concrete rehabilitation methods require extensive downtime as crews and equipment remove impacted areas and excavate and grade base soils before pouring new concrete, there is a better way of returning concrete structures to their intended positions. Specially formulated structural polyurethane foams have the strength to push once-sunken slabs back to level ground in a matter of seconds, and once cured they are durable enough to stop sinkage for years to come.
Quick to set and with an extremely high strength-to-weight ratio, the structural polyurethane foams we use have a variety of benefits. Examples include:
- Expands up to 25 times its initial volume
- Unaffected by standing water
- Displaces trapped water
- Not compromised by wet conditions during or after installation
- Not impacted by contamination, microbial corrosion and or high acid levels
EagleLIFT’s concrete structure lifting technique uses the impacted slab as a means to fix itself. Our highly skilled technicians drill ¾” holes through the slab and into supporting base soils in pre-determined locations. A metal rod is inserted into each hole, and the high-density structural polyurethane is injected. The polymer moves quickly throughout the aggregate and expands, curing into a strong, stable, and long-lasting replacement base material. Benefits of this process include:
- Increases load-bearing capacity
- Pushes out moisture
- Stabilizes soils
- Stops settlement
- Seals cracks
- Connects misaligned joints
- Strengthens durability
- Bolsters deformation resistance
- Increases stability
- Reduces permeability
A range of manmade and environmental factors can contribute to concrete structure sinkage. Common causes include:
- Inadequate support soils
- Wet or marshy environments
- Construction-related soil disturbance
The polyurethanes are inert, and are neither chemically nor biologically reactive and will not decompose. The following applications can benefit from EagleLIFT’s polyurethane lifting services:
- Commercial entities
- Industrial or manufacturing facilities
- Marine recreation centers
- Multi-family dwellings
