In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
In this step, low grit diamonds (e.g. 16- to 20-grit) are used to grind down all uneven surface until the floor is flat. [2] The next step is patching. Normally, all concrete floors have cracks. Patching ensures that all cracks, pinholes, and micropits are covered with grout before the concrete polishing process continues.
Repair principles which do not improve the strength or performance of concrete beyond its original (undamaged) condition include replacement and restoration of concrete after spalling and delamination; strengthening to restore structural load-bearing capacity; and increasing resistance to physical or mechanical attack.
In the category of self-leveling concrete there are two main groups of materials: underlayments and toppings. An underlayment is installed over an existing subfloor to smooth it out and correct any surface irregularities prior to the installation of all types of floor coverings, including sheet vinyl, vinyl composition tile (VCT), wood, ceramic tile and carpet.
Video from a traffic camera inside the Prudential Tunnel along Interstate 90 captured the moment when the concrete plummeted from the ceiling onto a vehicle, prompting drivers to slam on their ...
A solid ground floor consists of a layer of concrete, which in the case of a domestic building will be the surface layer brought up to ground floor level with hardcore filling under it. The advantage of a solid ground floor is the elimination of dry rot and other problems normally associated with hollow joisted floors.
