AP LIFT 430 T.D.S
DESCRIPTION
AP LIFT 430 is a two component, high strength, high density, hydro insensitive structural polyurethane foam. Unconfined density is approximately 3 lbs/cubic foot (48 kg/cubic meter).
USES |
|
| • Filling abandoned pipes, mine shafts, etc.
• Lifting concrete slabs. • Stabilizing soil. • Filling abandoned pipes. • Filling voids. |
|
ADVANTAGES |
|
| • Traffic ready in 15 minutes.
• High strength. • Works in wet environments – displaces water. • Bonds with soil and concrete. • Closed cell. • Certified by Truesdail Labs to NSF/ANSI 61-5 (approved for contact with drinking water).

APPLICATION |
Note: the following are a few typical application descriptions. In case of other jobsite parameters, please contact our technical department.
PRELIMINARY ANALYSIS
For slab lifting, soil stabilization, consolidation grouting, and all other forms of geotechnical grouting, it is advised to review soil reports from the job site. Take note of all structural elements and considerations and consult with geotechnical or structural engineers as needed. Locate all utilities prior to drilling or driving pipes into the ground.
PREPARATION OF THE SUBSTRATE
Soil probe spacing is most commonly 4-5’ (1.22-1.52 m) on center and as needed across the surface of the substrate. Depths will vary from job to job but must be established before work is to begin. Injection Technician should always confirm clearances and paths to injection sites for large equipment and/or Alchemy-Spetec mobile injection rigs.
PREPARATION OF THE PRODUCT
Read the technical and safety data sheets prior to commencement of the injection work.
PREPARATION OF THE EQUIPMENT
Alchemy-Spetec proportioning equipment in Cart System or Rig configurations should be tested to confirm equal flow and pressures from both A and B lines. MixMaster Pro should always be thoroughly inspected for cross-contamination or foreign buildup of any kind prior to injection.
APPLICATION
- Start the injection at the first probe and work way across grid pattern as needed taking note of travel of foam, connectivity to next hole location, and volumes used.
- Do not over pressurize while injecting; the correct injection pressure is the pressure that allows resin to penetrate the soils and/or fill the voids and keep the MixMaster Pro operating properly
- Take note of reaction time of material and be sure to purge injection gun regularly to prevent material curing in the gun.
- If lifting slabs, monitor lift with Alchemy-Spetec Dial Indicator Cranes to prevent over-lift.
- If stabilizing soil, pay attention to volume/vertical distance estimation and for material not penetrating and exiting around probe only.
- Clean the MixMaster gun thoroughly with Alchemy-Spetec pressure pot system, and cap supply lines.
- Run material through the pump as a maintenance step every 7-10 days.
REQUIRED TOOLS
Proportioning pump with heated lines, drill bits, MixMaster Pro injection gun, ports, Alchemy-Spetec Flush, soil probes.
CLEANING AND MAINTENANCE
After the injection, clean the pump with AP Flush 121. Conduct a full Alchemy-Spetec-recommended gun flush after every use. Material can remain in cleaned and capped lines. After injection, remove the packers from the concrete and fill the holes with a fast setting cement or any other appropriate filler material.
COMPLIMENTARY PRODUCTS
½” (12.7 mm) hydraulic tubing, flush pot, dial indicator cranes, airless flush pump, air compressor, ports, AP Flush 121.
ADVICE/FOCAL POINTS
Avoid injecting by temperatures below -4°F (-20°C). In extreme cold conditions it is recommended to warm both components to 60-80 degrees F (16 – 27 degrees C).
