NOVELTY - Processing leakage in wall construction involves mixing graphene oxide, Portland cement, expanding agent, water reducing agent, the gypsum and potassium sorbate. The obtained mixture is added with water that is 3-5 times of weight of the mixture. The obtained mixture is fully stirred for 10-15 hours to form cement paste. The obtained cement paste is kept stand for 3-4 hours to form a crystalline substance. The rubber is heated at 200-300 degrees C. The obtained product is cooled to normal temperature. USE - Method for processing leakage in wall construction. DETAILED DESCRIPTION - Processing leakage in wall construction involves mixing graphene oxide, Portland cement, expanding agent, water reducing agent, the gypsum and potassium sorbate. The obtained mixture is added with water that is 3-5 times of weight of the mixture. The obtained mixture is fully stirred for 10-15 hours to form cement paste. The obtained cement paste is kept stand for 3-4 hours to form a crystalline substance. The rubber is heated at 200-300 degrees C. The obtained product is cooled to normal temperature. The obtained product is kept stand for 3-4 hours to form strip. The cement mortar is placed in the first strip. The casting is finished, and kept stand for 3-4 days, forming a beam of the first waterproof strip at normal temperature. In the production of the intermediate wall, the second waterproof strip is laid in advance and passed through the polyester board, and the second waterproof strip is connected to the polyester board and heated to a temperature of 60-70 degrees C to bind the two. The two water-proof strips are covered with a polyurethane water-absorbing material, and are heated to a temperature of 50-60 degrees C at the junction to bond the two to form a waterproof structure and covering beam. The polyurethane foam is covered on the second water-proof strip. The joint is heated to 50-60 degrees C, bonding the two to form a lower waterproof and thermal insulation layer.
