F. Testing and Grouting of Joints and Defects - General

1. Attempt to test and, if needed, grout any joint separated less than 1 inch and/or any small or medium offset joint as classified by PACP . For joints separated by more than 1 inch or offset joints , the County or their representative may direct the Vendor to install a CIPPR to bridge the separated joint. The County or their representative may also direct the Vendor to install a CIPPR on joints separated by less than 1 inch that fails an air test.

2. Any structurally undamaged joint that structurally fails (breaks) during testing and /or grouting that are documented on video to have been done under normal pressure conditions shall be the County’s responsibility and cost to repair.

3. Test all circumferential cracks and fractures or other defects as specified or as specifically directed by the County or their representative . Do not test or grout any other pipe defects unless directed by the County or their representative . Any structurally failed pipe or joint that is grouted at the County’s or their representative’s direction that further fails ( breaks ) during testing and grouting that are documented on video to have been done under normal pressure conditions shall be the County’s responsibility and cost to repair. Promptly repair any other damage resulting from the Vendor’s operations at no additional compensation.

4. Attempt to test and, if needed, grout lateral connections using either a push packer or lateral grouting plug appropriately sized.

(302) 395-5250


Bid# 16A-009R

of 59

2. Individually test each sewer pipe joint which is not visibly leaking at a rate classified as a Runner (IR) or greater by PACP at the above-specified pressure (and retest after sealing) in accordance with the following procedure:

a. Air Test Procedure

1) The packer shall be positioned within the pipe in such a manner as to straddle the joint to be tested.

2) The packer ends shall be expanded so as to isolate the joint from the remainder of the pipe and create a void area between the packer and the pipe joint. The ends of the testing device shall be expanded against the pipe as per manufacture r’s recommendation. If all attempts to isolate the joint fail, pump grout in an attempt to seal the leak around the packer end elements. The Vendor shall be paid the unit price for grout to seal the packer unless the County or their representative determine s that the sewer was inadequately cleaned or the packer is not performing properly.

3) Air shall then be slowly introduced into the void area until a pressure equal to or greater than the required test pressure, but in no cases greater than 2 psi above the required test pressure, is observed on the pressure monitoring equipment.

4) After the void pressure is observed to be equal to or greater than the required test pressure, the air flow shall be stopped. If the void pressure decreases by more than 1.0 psi within 20 seconds, the joint will have failed the test and shall be injected with grout.

3. Upon completi on of the testing of each individual joint and/or defect , the packer shall be deflated with the void pressure meter continuing to display void pressure. Should the void pressure meter fail to drop to zero , clean the test equipment of residual grout material or make the necessary equipment repairs to provide for an accurate void pressure reading.

H. Testing Procedure for Lateral Connections

1. T esting pressure for l ateral connection s shall be equal to ½ psi per vertical foot of pipe depth plus 2 psi; however, test pressure shall not exceed 10 psi without approval of the County or their representative.

2. Air testing shall be accomplished by isolating the area to be tested with the lateral connection packer and by applying positive pressure into the isolated void area. A pan and tilt camera shall be used to position the lateral packer for laterals directly connected to the mainline sewer. The lateral bladder shall be inverted from the mainline assembly into the lateral pipe and inflated. The mainline elements shall then be inflated to isolate the lateral connection and the portion of the lateral to be tested. A sensing unit shall monitor the pressure of the packer void and will accurately transmit a continuous readout of the void pressure to the control panel at the grouting truck or to a pressure gauge on the packer read and recorded by the CCTV camera.

3. The test procedure will consist of applying a controlled air pressure into each isolated void area. A sensing unit shall be located within the void area and will accurately transmit continuous pressure readout to the control panel. Air shall then be slowly introduced into the void area until a pressure equal to or greater than the required test pressure, but in no case greater than 2 psi above the required test pressure, is observed on the pressure monitoring equipment. Once the designated pressure in the isolated void is displayed on the meter of the control panel, the application of air pressure will be stopped and a 30- second waiting period will commence. The void pressure will be observed during this period. If the void pressure drop is greater than 1 .0 psi, the lateral shall be considered to have failed the air test and shall be grouted and retested.

4. Upon completion of the testing of each individual joint and/or defect, the packer shall be deflated with the void pressure meter continuing to display void pressure. Should the void pressure meter fail to drop to zero, clean the test equipment of residual grout material or make the necessary equipment repairs to provide for an accurate void pressure reading.

5. For laterals capped less than two (2) feet from the main, the Vendor may use a mainline packer to test the lateral connection.

I. Grout Injection - General

1. Grout all joint s, defects , lateral connections that failed the pressure test or that are visibly leaking at a rate classified as a runner (IR) by PACP by the injection method. This shall be accomplished by forcing grout through a system of pumps and hoses into and through the joints and defects of the sewer from th e packer within the sewer pipe. Jetting or driving pipes from the surface shall not be allowed.

2. Remove excess grout from pipe and laterals. Excess grout shall be defined as a thickness of grout greater than 1 inch thick at any point or an amount of grout that, given its location, size and geometry, could cause a blockage as determined by the County or their representative . Flush or push forward to the next downstream manhole, remove from the sewer system, and pro perly dispose of excess grout.

J. Grout Injection for Mainline Joints and Defects

1. Position the mainline packer over the joint or defect to be sealed by means of a CCTV camera in the line. Position the push/pull packer over the joint or defect to be sealed by a means of visual observation, marked push rod, or where a cleanout is available, through a CCTV camera in the lateral. For push packers , start work from most upstream point to be grouted. Make accurate measurement of the location of the joint and/or defect to be sealed using a portion of the packer as a point of reference for positioning the injection area of packer over the joint or defect.

2. Pneumatically expand the packer sleeves such that they seal against the inside periphery of the pipe to form a void area at the joint now completely isolated from the remainder of the pipe line.

of 59

3. Pump grout materials into this isolated area . Run pump continuously until refusal with the goal of applying 0.25 to 0.5 gallons of grout per inch-diameter per pipe joint. No payment shall be made for joints or defects that take less than 0.1 gallons of grout per inch-diameter per pipe joint. Refusal shall mean the mixed grout has flowed through any joint or defect, through any annular space and into the surrounding soil; gelled or filled the available void space; and formed a cohesive seal stopping further grout flow. Record the amount of grout pumped on the sealing log.

4. The pump, meter and packer shall be integrated so that proportions and quantities of materials and pressure for materials and sealing gel can be instantly monitored and regulated in accordance with the type and size of the leak, percentage of voids being filled, type of soil surrounding the pipe, and the rate of flow of the sealing gel solution in relation to the back pressures. These parameters should follow the manufacturer’s specifications and guidelines.

5. Upon completion of the injection, deflate the packer to break away from the ring of gel formed by the packer void and move the packer at least one packer length in either direction . Move the television camera to a position to observe and inspect the results of the injection. If inspection and/or testing shows the seal was not completely effective, repeat the process.

6. The packer should then be repositioned over the joint, re-inflated , and the joint retested at a pressure equal to the initial test pressure. If the joint fails this air test, repeat the grouting procedure at no additional cost to the County. Repeat this sequence of air testing, grouting and subsequent air testing until either the joint is sealed or it is determined that the grout consumption is too high. The final determination to stop subsequent attempts to seal a joint will be made jointly between the County or their representative and the Vendor . Should the void

pressure meter not read zero ± ½ psi, clean the equipment of residual grout or make the necessary equipment repairs/adjustments to produce accurate void pressure readings.

7. If a mainline require s more than two (2) gallon s of grout per inch-diameter per pipe joint, modify grouting procedure to step grouting by pumping additional




(302) 395-5250


Bid# 16A-009R

of 59

grout in up to 4 gallon increments, waiting 1 gel set cycle time or 1 full minute, whichever is greater between steps, re-testing and, if needed, continuing with additional steps until a successful test is completed or until directed to stop by the County or their representative.

8. After the final post-grout pressure testing of each joint or defect, move the packer forward, wiping away the excess grout that extends into the pipe. Leave the sealed joints and/or defects reasonably flush with the existing pipe surface.

9. Confirm lateral flow after the sealing of each lateral through CCTV inspection. If a grout blockage is evident, clear the lateral.

K. Grout Injection for Lateral Connections

1. Each lateral tap connection in the test and seal segment that does not pass an air test or shows evidence of leakage shall be sealed with grout. The lateral packer shall remain in position during the pressure test, thus maintaining the isolated void. I nject grout through the lateral packer into the annular space between the lateral grouting plug and the lateral pipe and into the soil.

2. When pumping grout, run the pump continuously until refusal. Refusal shall mean the mixed grout has flowed through any joint failure, through any annular space, and into the surrounding soil; gelled or filled the available void space; formed a cohesive seal stopping further grout flow; and minimum of eight ( 8 ) psi back pressure is achieved while pumping. If the grout pumped exceeds 1 gallon per foot of lateral bladder plus 3 gallons, it will be suspected that there are significant voids on the outside of the pipe or that the packer is not properly sealed. Check that the packer is sealed properly. If it is, modify grouting procedure to step grouting by pumping additional grout in up to 4 gallon increments, waiting 1 gel set cycle time or 1 full minute, whichever is greater between steps, re-testing and, if needed, continuing with additional steps until a successful test is completed or until directed to stop by the County or their representative . Record the amount of grout pumped on the sealing log.

3. Upon completion of the lateral connection sealing procedure, air test the lateral connection a second time to confirm the sealing of the connection in accordance




(302) 395-5250


Bid# 16A-009R

of 59

with the air testing procedure. If the lateral conn ection fails this air test, r epeat this sequence of grouting and subsequent air testing until either the joint is sealed or it is determined that the grout consumption is too high. The final determination to stop subsequent attempts to seal a joint will be made jointly between the County or their representative and the Vendor . Air tests after grouting laterals containing roots is not required.

4. Confirm lateral flow after grouting of each lateral connection. With the lateral packer in position, retract the inversion tube and inject air pressure into the lateral. Should a pressure build in the lateral and not drop to approximately zero immediately after the pressurized air is turned off, move the packer off the connection and view the connection with a television camera. With the camera in viewing the connection point, attempt to obtain a flush of water by the occupant. If no water is viewed during this procedure, it will be assumed that the sewer lateral is substantially blocked with grout and the Vendor shall immediately clear the lateral at no additional cost to the County. Blockages in the lateral that are not the result of grouting operations shall not be the responsibility of the Vendor.

5. For laterals capped less than two (2) feet from the main, the Vendor may use a mainline packer to grout the lateral connection.

L. Joint Sealing Verification

1. Record grouting of joints in conjunction with the testing of joints. Record the void pressure drop continuously on video and in writing immediately before sealing, and immediately after grouting. After the packer is deflated and moved, record on video the visual inspection of the joint.

2. At the completion of the sewer line segment (i.e. manhole to manhole), conduct joint grouting verification testing of grouted joints and laterals for quality control purposes on 5% of the grouted mainline joints and/or defects (minimum of two repairs), and 25% of the grouted lateral taps (minimum of one lateral tap and excluding taps with roots not removed.) The County or their representative shall select the locations to be re-tested. Within a sewer line segment, if any joints, lateral taps or defects fail the retest after sealing, retest all joints, lateral connections and defects, as applicable, in the sewer line segment. Perform this




(302) 395-5250


Bid# 16A-009R

of 59

post repair testing and any additional testing/sealing required beyond the initial retest area at no additional cost to the County.

M. Disposal

1. Collect and properly dispose of cleaning materials used in the cleaning of the grouting equipment.

N. Test and Seal Grouting Acceptance

1. All work shall be witnessed by the County or their representative.

2. Acceptance and payment for each test and seal operation shall be based upon the County’s evaluation of submittals required . All tests utilized by the County for the purpose of establishing compliance with this specification shall be in accordance with the applicable ASTM standard.

3. Submittals

Each active lateral connection shall be completely opened and shall have smooth edges with no protruding material capable of hindering flow or catching and holding solids and debris contained in the flow stream. The opening shall not be more than one hundred percent (100%) of the lateral connection pipe opening. If the lateral connection cannot be fully reopened due to time constraints, open each lateral to a minimum of seventy-five (75%) before the end of each working day. Partially opened connections must be entirely reopened by the end of the next day. It is the Vendor’s responsibility to make sure that all active lateral connections are reconnected to the main pipe.

a. The coupon of pipe liner material resulting from lateral connection cutting shall be collected at the next downstream manhole and removed from the sewer collection system by the end of the working day.
