EDITOR’S CHOICE Mapei cements a tough bond with Mapeproof FBT Mapeproof FBT by Mapei is a pre-applied synthetic waterproofing membrane with a non- woven fabric backing applied in full adhesion to protect structures below ground level. It is able to withstand up to 7 bars of pressure, and provides Radon and Methane protection. Mapeproof FBT is applied underneath foundation slabs and against diaphragm, pile walls, sheet piling and other permanent retaining structures. The waterproofing system is suitable for a range of applications including basements, garages, car parks, swimming pools, basins, storage tanks, underpasses and underground areas in general. The fully-bonded waterproof sheet membrane system incorporates two Mapei adhesive tapes: Mapeproof FBT Tape, used to bond joints between the upper-facing side of adjacent membranes in the system, and Mapeproof SA Tape, for bonding joints between the lower- facing sides of adjacent membranes. With extreme flexibility, Mapeproof FBT is easy to install. The waterproofing membrane is cold-applied (between +5°C and +35°C), thus no heat or naked flames are required on site. Positioned before placing the steel reinforcement and pouring of the concrete, joints can be bonded on horizontal or vertical surfaces and shaped to follow the geometry of the substrate, ensuring a longstanding tough bond; due to its bond, Mapeproof FBT prevents water from migrating laterally between the foundation structure and the membrane, once concrete has been poured. It does not require a protective layer. The certified Mapeproof FBT waterproofing system also consists of two double-sided adhesive tapes. Mapeproof Fix Tape is used to hold the waterproofing membrane in place during installation. Meanwhile, Mapeproof BA Tape, a waterproof synthetic tape, is used for treating fillet joints between horizontal and vertical surfaces, as well as those between adjacent vertical surfaces.

These partially collapsed rubble stone walls had suffered from years of weathering and deterioration but were now to be incorporated into the annexe of a modern farm conversion. Flexible HeliBars were used to stabilise the ruins as they offered the ideal solution due to the irregularities in the direction of the mortar beds. HeliBars were also suitable for reinforcing the chimney breasts and fireplaces which were important features to be retained from the previous split-level property the ruins once were. Once the concealed installation was complete, the ruins were fully stabilised and reinforced. The original materials were retained, structural integrity restored and the ancient walls could now be incorporated into the new annexe.
