NCFI GEOTECHNICAL - TERRATHANE 24-010 POLYURETHANE FOAM INSTALLATION SEQUENCE THE FOLLOWING INSTALLATION STEPS PROVIDE A BROAD OVERVIEW OF TERRATHANE GEOTECHNICAL 24-010 POLYURETHANE FOAM INJECTION BENEATH A CONCRETE SLAB OR PAVEMENT. INTERMEDIATE STEPS, INSTALLATION EQUIPMENT AND TOOLS USED, AND CONSIDERATIONS FOR UNUSUAL CONDITIONS OR APPLICATIONS ARE NOT ADDRESSED. STEP 1: ACCESS/APPLICATION HOLES ARE DRILLED (%"O) AT STRATEGIC LOCATIONS IN THE SLAB. IN GENERAL, THE HOLES ARE SPACED 5 FEET APART AND 3 FEET FROM THE EDGES OF THE SLAB. LOCATIONS AND SPACING ARE OFTEN MODIFIED IN THE FIELD TO ACHIEVE THE DESIRED RESULT. STEP 2: INJECTION PORTS ARE PLACED TO SEAL THE HOLES. STEP 3: TERRATHANE GEOTECHNICAL 24-010 POLYURETHANE FOAM IS INJECTED TO FILL VOIDS AND ALLOW FOR LIFTING. LIFT MAY BE MONITORED WITH SURVEY EQUIPMENT OR STRING LINES. STEP 4: THE INJECTION PORTS ARE REMOVED AND THE HOLES ARE PATCHED WITH MORTAR MIX, NEXUSPRO SILICONE JOINT SEALANT, OR EPDXY SEALANT. TERRATHANE GEOTECHNICAL 24-010 POLYURETHANE FOAMS ARE MOST OFTEN USED BENEATH EXTERIOR CONCRETE SIDEWALK AND PAVEMENT SECTIONS FOR STABILIZATION OR RELEVELING, BUT ARE ALSO UTILIZED FOR INTERIOR WORK AND OTHER SPECIALTY APPLICATIONS. TERRATHANE GEOTECHNICAL 24-010 POLYURETHANE FOAM IS OFTEN CONSIDERED AS AN ALTERNATIVE TO MUDJACKING OR REMOVAL AND REPLACEMENT. SETTLEMENT OF RESIDENTIAL SLABS IS TYPICALLY THE RESULT OF CONSOLIDATION OF POORLY COMPACTED FILL SOILS AROUND FOUNDATIONS AND WITHIN UTILITY TRENCHES, SOFTENING OF WEAK NATIVE SOILS AND FILL DUE TO INCREASES IN MOISTURE CONTENT, AND EROSION OR WASHOUT CONDITIONS RESULTING FROM POOR DRAINAGE. CRACKED SLABS, FAULTING BETWEEN SLAB SECTIONS, AND/OR OTHER OBVIOUS DOWNWARD VERTICAL MOVEMENT ARE TYPICALLY THE FIRST OBSERVABLE SYMPTOMS OF SETTLEMENT FROM THE SURFACE, THOUGH VOIDS MAY ALSO BE PRESENT BELOW AS RIGID SLABS CAN SPAN BETWEEN SUPPORT POINTS. WHEN VOIDS ARE PRESENT, USING INERT, HYDROPHOBIC TERRATHANE GEOTECHNICAL 24-010 POLYURETHANE FOAM ALLOWS FOR UNDERSEALING OF THE REGION, PREVENTING ANY FURTHER WASHOUT AND ACTING TO AGAIN PROVIDE UNIFORM SUPPORT TO THE BRIDGED CONCRETE. WHEN SLABS HAVE SETTLED, WITH OR WITHOUT THE PRESENCE OF VOIDS, FOAM CAN BE INJECTED TO CREATE LIFT WITHOUT ADDING SIGNIFICANT WEIGHT TO THE UNDERLYING SOIL. TERRATHANE GEOTECHNICAL 24-010 POLYURETHANE FOAM IS INSTALLED WITH CUSTOM—BUILT INSTALLATION RIGS AVAILABLE AS TRUCK —MOUNTED OR TRAILER UNITS. THE BASIC COMPONENTS OF THE SYSTEM INCLUDE MATERIAL STORAGE TANKS, A GENERATOR, AN AIR COMPRESSOR, PUMPS, A PROPORTIONER, AND APPLICATOR(S)/ GUN(S). THE PROPORTIONER INCLUDES A MATERIAL HEATER, PRESSURE REGULATOR, STROKE COUNTER, AND INSULATED AND HEATED HOSES. THIS ENSURES THAT THE TWO PARTS ARE DELIVERED TO THE APPLICATOR AT A CONSISTENT PRESSURE AND TEMPERATURE.
