PRODUCTS & SOLUTIONS TOP HDM MAXI, PLANITOP HDM RESTAURO, carbon fibre and glass fibre fabrics from the MAPEWRAP line, admixtures for concrete, and products for masonry repair from the MAPEANTIQUE line. SPAIN Various buildings were damaged by the earthquake that hit Lorca in May 2011. These were subsequently repaired and strengthened using Mapei products and technology. Residential and commercial building The well-known residential and commercial building at No 6, Calle Alberca was made of reinforced concrete. It has one storey below ground level and five storeys above ground level. Repair work was carried out on the pillars of the building which had been damaged by the earthquake. It included filling the cracked areas with EPOJET, rebuilding some concrete sections of the pillars by protecting the reinforcement rods with MAPEFER 1K and applying MAPEGROUT T40 and MAPEGROUT HI-FLOW mortars. Strengthening work was carried out by wrapping the pillars with MAPEWRAP C UNI-AX unidirectional carbon fibre fabrics. Church of San Cristobal In the renovation and strengthening of the Church of San Cristobal which had been damaged by the earthquake, Mapei provided technical assistance, from the design phase right up to the execution phase. The first phase of the work consisted in strengthening the arches, in the central nave, with MAPEWRAP C UNI-AX unidirectional carbon fibre fabrics, which were applied with resin-based products from the MAPEWRAP epoxy cycle. MAPEWRAP C FIOCCO glass fibre cord was also applied to help protect the fabric. Detached house A detached house at No 7A Poeta Gimeno Castellar Road in Lorca had

been severely affected by the earthquake, with damage to the loadbearing walls, the façade, the slabs and various internal elements and features. Mapei was involved in the reconstruction of the two-storey masonry building, right in the heart of the city. The load-bearing walls were consolidated by injecting MAPEANTIQUE I binder into the masonry, which was then reinforced with PLANITOP HDM MAXI mortar and MAPEGRID G220 mesh. MAPEGRID G120 was also used on the internal walls.
