Environmental Technology Verification Program for Grouts Used in Infrastructure Rehabilitation
Grouts are being used in the rehabilitation of various infrastructures including all types of wastewater facilities and cracked concrete structures to control leaks. Hence there was a need to develop test protocols to evaluate the performance of various types of grouts based on their applications. The aim of the controlled testing program at the Center for Innovative Grouting Materials and Technology (CIGMAT) was to evaluate the performance of grouting materials used in the rehabilitation of wastewater facilities and cracked concrete structures to quantify the infiltration at pipe joints using a combination of model and laboratory tests. A combination of grout, grouted sand, grout-substrate bonding and four model tests are being used to evaluate grouts for leak control at pipe/manhole joints, service connections and cracks in concrete. Grouts are being characterized using the working, physical, mechanical and durability properties. To quantify the grout and grouted sand properties several ASTM and CIGMAT test methods are being used. For the leaking joint model tests, 203 mm (8") diameter leaking pipe joints are being used in soil boxes. Concrete crack repairs are simulated using concrete rings placed at selected distance apart. Grouted joints and cracks are being tested to 34 kPa (5 psi) water pressure to quantify the effective reduction in infiltration. The controlled verification test program approved by the EPA will be of assistance to manufactures, suppliers, engineers and owners.
