The area of the research is geoconstruction and geostructures in transport. The present study provides modified repair mortars characterized by high penetrating performance, which is important in geoconstruction and transport. Penetrating repair mortars increase compression strength by 1-3 classes, water-resistance by 4-10 atm of the operated concrete geofoundation. Modified repair mortars are of increased crack resistance, they are carbon dioxide and magnesia corrosion resistant material and also they are characterized by high adhesion strength to a concrete geofoundation, which creates a monolithic character of both a restored foundation and a repair geocomposition.
