Lateral Test and Seal Packers Logiball 2001L packers are used to test and seal off infiltration in sewer laterals, from the mainline, without any access to cleanouts. The lateral grouting plug is inverted and deployed into the lateral from the mainline packer assembly. The mainline sleeve then expands to create a minimal grout mixing chamber. The grout is pumped and migrates freely along the restricted expansion of the lateral plug and out through existing pipe defects into the surrounding bedding to seals defects, leaving only a thin layer of grout in the lateral. The packers are available with different void pressure monitoring systems; a conventional localized liquid filled sensor (S), recommended for acrylamide and acrylate grouts, an in-wall water chamber sensor (W), recommended for stickier grouts such as urethanes and polyurethanes, or both systems (S+W) for a more versatile use. The 2001L Lateral Packer comes standard with two grout ports and a third port dedicated for the test medium (air or water). 2001L Lateral packers work best with a five-hose system. Lateral Grouting Plugs can be interchanged in a matter of minutes to grout distances up to 30 feet if necessary. Lateral Grouting Plugs are available for 4, 5 or 6 diameter laterals. Flexible housing extensions are needed for lateral grouting plugs 24 or longer. ICGA promotes the proper use of chemical grouting as a safe, economical and effective means to reduce ground water infiltration into sewer collection systems. The 2001L model is available for 6â?³, 8â?³, 9â?³, 10â?³, 12â?³, 15â?³, 18â?³, 21â?³, 24â?³ and 30â?³ mainlines. For larger diameter contact our sales department.
