Waterproofing of corners and intersections with mortar

Reinforcement of waterproofing of corners and intersections between concrete, concrete or concrete block facades, by opening a continuous 2x1 cm groove, forming straight edges, introducing a deformable and watertight joint and sealing with a watertight and deformable mastic, and finishing at a concave angle, at half height, with a repair mortar, modified with polymers, reinforced with fibers, of very high mechanical resistance and compensated retraction, with a compressive strength of 28 days greater than or equal to 50 N/mm² and a modulus of elasticity greater than or equal to 20000 N/mm², class R4, type PCC, according to UNE-EN 1504-3, Euroclass A1 fire reaction, according to UNE-EN 13501-1, composed of special cements, selected aggregates, additives and fibers, applied in several layers, with a curvature radius of 10 cm.
