� • <br /> G3IGROUP <br /> �:�.�- <br /> 5.5 Tubing shall be used for injection of the polyurethane material into the soil. <br /> The tubing should be pressed into place or installed with a pneumatic hammer <br /> to ensure immediate contact with the surrounding soils to minimize material <br /> travel along the annulus. <br /> 5.6 Tubing should be extracted via the method determined most suitable <br /> for the site by the Engineer and Contractor,based on site conditions. <br /> 5.6.1 At uniform short intervals,progressing towards the ground <br /> surface,or � <br /> � <br /> 5.6.2 At one or more pre-determined depth intervals <br /> 5.6.3 As determined otherwise by the Engineer , <br /> 5.7 If tubing becomes locked into the polyurethane material,it shall be cut off a � <br /> minimum of six inches below the ground surface. <br /> 6.0 Polyurethane Injection <br /> 6.1 Void filling/Slab leveling—As necessary,polyurethane material shall first be <br /> injected through a series of 5/8"—3/4"drilled holes until all known or <br /> encountered voids directly under the structural element(slab,pool deck,etc.) <br /> are filled and the element has been leveled to the extent practical. The rate and <br /> amount of material injection shall be determined by the Contractor and the <br /> engineer based on site conditions. <br /> � <br /> I <br /> 6.2 Subsurface Injection—The polyurethane material shall then be injected. <br /> 7.0 Monitoring <br /> 7.1 Continuous laser level or dial indicator micrometer readings shall be in place <br /> and monitored by the Contractor during injection to determine sufficient <br /> material usage and soil treatment as indicated by any recordable <br /> movement in the ground surface or overlying structural element. <br /> 7.2 Contractor shall record the location and the uanti of material in'ected at <br /> q h' J <br /> each grout location. <br />', 8.0 Basis of Payment <br /> The accepted quantities of polyurethane material as displayed by the certified <br /> flow meter,will be paid by the client at the contract unit price upon � <br />, acceptance of the quantity by the Engineer.
