Mapei Mapefill 318 is a high-performance, shrinkage-compensated cementitious grout designed for filling structural voids and spaces where high strength, stability and reliable load transfer are required. Its highly flowable and pumpable consistency allows the grout to effectively fill confined and difficult-to-access areas while helping minimise shrinkage as it hardens.

Suitable for a wide range of construction and engineering applications, Mapefill 318 can be used for grouting beneath base plates, machinery and equipment foundations, precast concrete elements, structural supports, anchor locations and other precision grouting applications. Supplied as a pre-blended cementitious product, it provides a practical solution for structural grouting where conventional mortar may not provide the required flow, strength or dimensional stability.
