Webercem lightweight is a polymer-modified, cementitious mortar mix, with specially selected lightweight fillers. It is preblended, contains a polymer powder and simply requires the addition of clean water to produce a mortar suitable for both soffit and vertical repairs in situations where high-build replacement with conventional concrete is impractical.

Since its introduction in 1985 Webercem lightweight has been widely used in concrete repairs because of its ability to be applied on to vertical and soffit surfaces. This product has been formulated to comply with the requirements of BS EN 1504-3 as an R2 mortar.
