Engineered Hybrid Epoxy Cement
WHAT IS AN EPOXY CEMENT LINER?
An epoxy cement liner is both an epoxy and cementitious liner combined into one technology forming a hybrid epoxy modified mortar for rehabilitation and lining of wastewater and sanitary sewer infrastructure. The system offers advantages of epoxy coating with the economics and simplicity of cementitious lining. Formulated for low-to-moderate hydrogen sulfide (H2S) conditions (up to 100 ppm). This unique combination of cement enhanced with epoxy crosslinking delivers economics of cements together with performance of epoxy.
The cured material differs from traditional cementitious lining such as calcium aluminate, microsilica, and geopolymers which are susceptible to erosion due to the lack of high crosslinking polymerization. Because the cement not only undergoes its curing mechanism, the epoxy polymerization further enhances crosslinking and cure properties turning the cured material into a higher density, resin protected, enhanced cement-epoxy hybrid lining system. This combination increases impermeability, acid resistance, adhesion, and elevates a variety of mechanical properties important in lining applications such as flexural and tensile properties.
ECONOMICS + PERFORMANCE
The benefit of epoxy-cement lining is the is provides an economical, simplified methods of repair and protection. For severe wastewater and high hydrosulfuric (H2S) environment, Epoxytec offers the structural epoxy liners. However, there are countless applications where overspending and overkill can be avoided, saving both time and money. Low-to-moderate H2S environments can benefit from a cost-effective lining system such as an epoxy-cement liner with the Mortartec Cladliner.
WHEN SHOULD I CONSIDER AN EPOXY-CEMENT LINER?
Epoxy-cement liners should be considered as an upgrade to other cementitious lining systems not designed for moderate H2S environments or erosion. Because the cement curing is further enhanced by epoxy polymerization, the material provides a higher level of sealing, permeability resistance, and erosion protection; yet provides economical rehab and lining when exposure is low-to-moderate H2S.
