SERVICES PROVIDED BY L.R.E. GROUND SERVICES, INC.
COMPACTION GROUTING
Also known as Soil Stabilization, Compaction Grouting is done by pumping cement into the ground through steel casing under pressure to seal the limestone and compact soils.
Steps to Completion
1. Drill grout injection points.
2. Insert steel casing to pump cement.
3. Pump cement through each injection point.
4. Remove steel casing.
5. Cover each injection
6. Clean up the work site
CHEMICAL GROUTING
Shallow Chemical Grouting is used to improve soil capacities and strengths. It can be completed using two different types of urethane resins. The first is a two-part resin that expands to compact the underlying soil. The second is a single component resin that permeates the soil, using a catalyst to strengthen the underlying soil. Smaller diameter injection pipes are used, which help make the completion time quicker.
Steps to Completion
1. Lay out locations for injection pipes.
2. Install ¼” – 5/8” diameter injection pipes approve depths.
3. Inject the proper amount of resin to improve the underlying soils.
4. Work site is cleaned up.
UNDERPINNING
Underpinning or Pin Piles are installed to repair structures that have been damaged or have settled due to subsidence, buried debris, clays or organics. L.R.E.'s underpinning includes a limited lifetime warranty for its material and workmanship.
As an authorized and fully trained Foundation Supportworks dealer, L.R.E. uses the Foundation Supportworks Pier System for all its Underpinning/Pin Pile projects.
Steps to Completion
1. Excavate the soil below and around the foundation.
2. Put brackets in place
3. Hydraulically advance or drill steel casing to limestone or bearing strata.
4. Install leveling rams on each pier to lift the structure back to its original state.
5. Transfer weight of home to piers.
6. Clean up the work site.
Helical Piers allow homes and commercial buildings to rest on deep, stable soil. They stabilize the foundation. This cost-effective system usually doesn’t require heavy equipment and can be installed year-round. Helical Piers come with a lifetime warranty. 
Steps to Completion
1. Mechanically screw to deep, stable soils.
2. Transfer weight of foundation from unstable soil to load-bearing piers.
3. Work site is cleaned up.
PRE-CONSTRUCTION HELICAL PIERS
Pre-construction Helical Piers are used when building new structures that could have settlement problems due to buried debris, clay, muck, etc.
Steps to Completion
1. Use a drill rig to advance the piers to a more competent bearing strata.
2. Each pier is installed where the structure foundation or bearing walls will be placed during construction, so that the structure will not be affected by the upper material that could cause settlement problems.
3. Work site is cleaned up.
INTERIOR SLAB BRACKETS
The ISB-07 is an interior slab bracket that has extreme spanning capabilities. The bracket has three 16” or 24’ inch arms The strength of the bracket’s arms reduce the quantity of brackets needed under the interior slab, leading to a tremendous savings. Powder Coating is also available. View the Specs
Steps to Completion
1. Core a 10-12” diameter hole in slab.
2. Excavate soil beneath slab to allow arms to open once slab is inserted.
3. Insert hydraulic ram between plates and pressurize to restore slab to level condition.
4. Clean up the work site
INJECTION PIERS
Injection Piers are underpins that have several 1 ½” openings in the steel casing. The perforated pipe allows L.R.E. to pump grout through the casing to permeate the soil surrounding each pier. This gives the underpins more stability and enables L.R.E. to compress and compact soil around the pins.
Steps to Completion
1. Prep foundation for installation of bracket assembly.
2. Using a hydraulic ram, hydraulically advance the pier to competent bearing strata.
3. Using water, flush the inside of the pier to clear out any debris.
4. Pump grout through injection piers.
5. Clean up worksite.
SHALLOW GROUTING
Shallow Surface compaction is done by pumping cement into the upper 5’ to 10’ soils. This is designed to permeate the upper soils to compact them.
Steps to Completion
1. Install small diameter steel casing up to 1.25 inches.
2. Inject portland-based cement grout under low pressure and low volume to prevent damage to the structure.
3. Cover the injection points.
4. Clean up the work site.
SLURRY GROUTING
Slurry Grouting is used to fill voids below a slab or foundation. When a void or gap below a floor slab or foundation is present, there can be stress to these areas that can cause damage and/or displacement.
Steps To Completion
1. Core small perimeter holes into the concrete slab.
2. Pump a loose grout mixture below the slab to fill the voids
3. Once the grout has set up, smooth out the holes with cement.
4. Clean up the work site
SLAB RE-LEVELING
A two part urethane resin is mixed evenly to produce a strong, rigid, expanding foam. It is light weight, has more precise control of lifting, takes less pressure to install and completion time is cut in half.
Steps to Completion
1. Resin is injected in 3/8” – 5/8” holes drilled through concrete slab.
2. Resin begins to expand to fill the voids under the slab.
3. Soil below the slab begins to compact, allowing lift to re-level areas of slab.
4. Clean up the work site.
SLURRY GROUTING/VOID FILL
Slurry Grouting is used to fill voids below a slab or foundation. When a void or gap below a floor slab or foundation is present, there can be stress to these areas that can cause damage and/or displacement.
Steps To Completion
1. Core small perimeter holes into the concrete slab.
2. Pump a loose grout mixture below the slab to fill the voids
3. Once the grout has set up, smooth out the holes with cement.
4. Clean up the work site.
CRAWL SPACE STABILIZATION
Crawl Space Sta
bilizers are used as an adjustable, supplemental support system in crawl spaces to stabilize and oftentimes lift failing joists or beams. It can also lift the floors and walls back to level.
Steps to Completion
1. Rest the Crawl Space Stabilizer on a concrete base, which is placed on engineered fill.
2. Secure an adjustable, heavy duty steel column to both the concrete base and the bottom of the beam or joists above.
3. Clean up the work site.
SLAB JACKING
Slab Jacking is done to fill voids between the slab of the structure and the soils that lay beneath the structure with cement. Once the void is filled the slab can be lifted to its original state.
Steps to Completion
1. Core 4” holes into the slab.
2. Install grout injection plugs into each hole.
3. Lift the slab and allow cement to harden.
4. Remove plugs.
5. Smooth off injection holes with cement.
6. Clean up the work site.
