Waterstops are manufactured from a variety of materials depending on the functionality and their intended use. The most common types are: Waterstops made from extruded plastics such as flexible polyvinyl chloride PVC, polyethylene (PE) or thermoplastic vulcanized rubber (TPV); formed metal such as stainless steel, copper, or carbon steel - with or without polymeric coatings; extruded ...
Concrete roofing is composed of concrete reinforced with fibers of some sort. Structural concrete can also be used for flat roof constructions. There are three main categories, precast/prestressed, cast-in-place and shell. There are many types of precast/prestressed concrete roofing. The following are the most common types. [8]
Rubber cement (cow gum in British English) is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep it fluid enough to be used. This makes it part of the class of drying adhesives: as the solvents quickly evaporate, the rubber solidifies, forming a strong yet flexible bond.
The typical capillary tube mat has capillary tubes with an external diameter of less than 5 mm. This makes the construction very flexible, and emphasizes the property of the "mat". The individual capillary tubes are arranged in a grid with a spacing of 10 to max. 50 mm from each other.
These are in the shape of hollow tubes, and are usually used for columns and piers. The formwork stays in place after the concrete has cured and acts as axial and shear reinforcement, as well as serving to confine the concrete and prevent against environmental effects, such as corrosion and freeze-thaw cycles. Flexible formwork. In contrast to ...
Uses include the underside of roof sheathing, ceilings, and on walls. For best results, this should not be used as a cavity fill type insulation. Foil-backed bubble pack. This is thin, more flexible than rigid panels, works as a vapor barrier, and resembles plastic bubble wrap with aluminum foil on both sides.
Some types of rubber expansion joints are made with a molding process. Typical joints that are molded are medium-sized expansion joints with bead rings, which are produced in large quantities. These rubber expansion joints are manufactured on a cylindrical mandrel, which is wrapped with bias cut fabric ply.
Popcorn ceiling texture. A popcorn ceiling, also known as a stipple ceiling or acoustic ceiling, is a ceiling with one of a variety of spray-on or paint-on treatments. [1] The bumpy surface is created by tiny particles of vermiculite or polystyrene, which gives the ceiling sound-deadening properties. Mixtures are available in fine, medium, and ...
