The popular trend in trench drains are linear systems. Linear as in line drain. Made from materials such as polymer concrete, fiberglass, structural plastic and steel, liner systems are the channel and grate components that are assembled in the trench and around which concrete is poured to form a drain system. By themselves, these liner systems ...
[2] [3] [4] A recent study was conducted that shows that diamond grinding is an effective means of extending the service life of concrete by imparting a smooth pavement surface with desirable surface texture. The process can also be used to address faulting at joints or cracks, roughness, polished concrete surfaces exhibiting inadequate ...
Some spaces are large enough to require additional work to prevent water from moving along them and re-entering the waste stream, for example: insertion of hydrophilic material which swells to fill the void; lining of the entire connection and host pipe with continuous repair (YT repair) gaskets; and point repairs placed at the ends of the host ...
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
When atmospheric carbon dioxide (CO 2), or carbonate ions (HCO − 3, CO 2− 3 dissolved in water) diffuse into concrete from its external surface, they react with calcium hydroxide (portlandite, Ca(OH) 2) and the pH of the concrete pore water progressively decreases from 13.5 – 12.5 to 8.5 (pH of water in equilibrium with calcite).
[1] [2] Therefore, it is essential to limit the crack's width and repair it as quickly as feasible. Self-healing concrete would not only make the material more sustainable, but it would also contribute to an increase in the service life of concrete structures and make the material more durable and environmentally friendly.
