In building construction, waterproofing is a fundamental aspect of creating a building envelope, which is a controlled environment. The roof covering materials, siding, foundations, and all of the various penetrations through these surfaces must be water-resistant and sometimes waterproof.
CFRP has become a notable material in structural engineering applications. Studied in an academic context as to its potential benefits in construction, it has also proved itself cost-effective in a number of field applications strengthening concrete, masonry, steel, cast iron, and timber structures.
Concrete repair by pressure grouting or jet grouting involves injecting a grout material into otherwise inaccessible but interconnected pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or chemical mixture.
Rigid insulation is made from fibrous materials (fiberglass, rock and slag wool) or from plastic foam. They are sometimes sold in sections designed to fit tightly in standard wall cavities. Reduce heat conduction through the wall frame when used as sheathing. Rigid panels with a radiant heat barrier facing foil will significantly improve the insulating properties by reflecting infrared solar energy before penetrating the wall or ceiling.
There are three major steel fasteners used in industries: stainless steel, carbon steel, and alloy steel. The major grade used in stainless steel fasteners: 200 series, 300 series, and 400 series. Titanium, aluminum, and various alloys are also common materials of construction for metal fasteners. In many cases, special coatings or plating may be applied to metal fasteners to improve their performance characteristics by, for example, enhancing corrosion resistance.
Epoxy floors offer a reliable and durable surface for commercial and industrial flooring. Epoxy floor coatings are normally applied over concrete floors to provide a high performance, smooth and durable surface that can last many years or withstand heavy loads. Many industrial buildings, warehouses and commercial buildings require to have epoxy floors as they need to maintain the floors in perfect conditions, and the only way or easiest way is by having epoxy floors.
