SECTION 4 – SANITARY <br />48 <br />iv.Approved Manufacturers/Products: <br /> Deneef Hydroactive Cut <br />Sealguard <br />Approved Equal <br />3.) Protective Coating Material: The resin based material shall be used to form the sprayed <br />structurally enhanced monolithic liner covering interior surfaces of the structure, from the <br />inverts including flow line of manholes through the barrel sections, up to and including the <br />cone. The finished liner shall be SprayWall® as manufactured by Sprayroq, Inc. or approved <br />equal and conform to the minimum physical requirements listed below. The physical <br />requirements must be verified by an independent, certified, third party testing laboratory within <br />the last five (5) years and must be submitted with the bid package. Any bid package not <br />including the verifiable, independent third-party testing shall be ruled non-responsive and will <br />be rejected. <br />Compressive strength ASTM D 695 > 18,000 psi <br />Tensile strength ASTM D 638 > 7,450 psi <br />Flexural strength ASTM D 790 > 14,000 psi <br />Bond Substrate Failure <br />Flexural modulus (initial) ASTM D 790 > 735,000 psi <br />Long Term Flexural Modulus ASTM D2990 >529,000 psi <br />Density 87 ± pcf <br />Tensile Modulus ASTM 638 >425,000 psi <br />Chemical Resistance: Severe Municipal Sewer <br />Service Successful Pass: SSPWC 211-2 <br />When the wall of the resin-based liner is to be structurally designed to withstand the hydraulic <br />load generated by the groundwater table the long term [fifty (50) year] value of the flexural <br />modulus of elasticity will be utilized to calculate the thickness of the structural liner. A <br />minimum groundwater depth of five (5) feet above the invert shall be used in the design of the <br />liner. The minimum value for coating thickness for both concrete and brick structural <br />rehabilitation shall be 250 mils. The initial flexural modulus of elasticity (short term) of the <br />submitted resin material will be utilized with the long-term deformation percentage as <br />determined by ASTM D2990 in the design equation outlined in ASTM 1216-07b, Appendix <br />X1. The value of the long term flexural modulus of the proposed product will be certified by <br />an independent, certified, third party testing lab, independent of the Manufacturer, and <br />submitted with the bid package. [The definition of long term value will be identified as initial <br />flexural modulus of elasticity less the reduction in value caused by Creep over a fifty (50) year <br />minimum period and verified by third party DMA testing (ASTM D2990).] All design <br />submittals will include this certified third-party DMA testing (ASTM D2990) value in their <br />respective design calculations for each structure being rehabilitated. <br />A flexible polyamine epoxy shall be used for the spacer rings. The finished liner on this portion <br />of the manhole shall be Parsonpoxy FP or approved equal. <br />Other Materials: Because of the advantages associated with rapid cure and infinite thickness <br />capabilities, no resin based materials other than polyurethane shall be used to achieve the <br />structural enhancement without prior approval of the City Engineer.
