over time, your driveway will start to crack and corrode. even with regular sealing, the smooth surface will eventually wear down due to damage from uv rays, salt, oil, gas and harsh weather. when the cracks become unsightly and unsafe, there are two basic options: resurface or repave.
by contrast, wear and damage to asphalt and concrete driveways are difficult to remedy and replacement is often more cost-effective than extensive repairs. gravel is also less vulnerable to damage from seasonal freeze-thaw cycles, or frost heave, which can cause significant cracking and settling in solid driveway materials.

construction of pavement designs shall comply with the dpti master specification for roadworks. conformance with this specification is a fundamental prerequisite to achieving the design parameters provided in this supplement, and the pavement life. where there is a difference between content in the guide and this supplement, the
first, concrete is stripped of any existing sealer or coatings and any visible cracks are repaired. this is followed by the polishing process using the floor grinders mentioned above. part way through the polishing process, chemical hardeners are often added to the concrete to provide future protection against water infiltration.

“what are the benefits of using paint on concrete?” there are several benefits, including: water and ice resistance; temperature resistance, both hot and cold; resistance to physical abuse by high traffic from people and light vehicles; resistance to
the most common cause of steel rebar corrosion is exposure to de-icing salt used for roadways. if the concrete and rebar are not protected, the salts will eventually reach the depth of the rebar and cause corrosion. exposed concrete structures such as parking garages, sidewalks, and bridges in cold climates are most at risk.

people just need to realize that when you deal with a company who does many different projects, they have a lot of balls in the air sometimes and if something falls through somewhere else, they can sometimes fit you in. other times weather and other factors may play into your plans and there is nothing that can be done about it.
concrete can deteriorate for a variety of reasons, and concrete damage is often the result of a combination of factors. the following summary discusses potential causes of concrete deterioration and the factors that influence them. corrosion of embedded metals fig. 1. corrosion of reinforcing steel is the most common cause of concrete deterioration.
driveway pavers lie somewhere in between these two main categories because there are cracks between the individual pavers. although these pavers are individual components that are pieced together to form a whole, some types of pavers can, if laid properly, form an almost seamless, even surface, with no raised areas to give your snowblower fits.
this extra effort taken before pouring the concrete will keep your driveway in better shape for the long term. low-quality subgrades and subbases can lead to
cracks less than about 10 mm (0.375 inches) in width may be too narrow for crack-sealing material to enter. these narrow cracks can be widened with a mechanical router before sealing. if the existing pavement has an excessive amount of fine cracks but is still structurally adequate, it may be more economical to apply a general bituminous surface treatment (bst) or slurry seal instead of filling each
a fresh concrete mixture is a fluid, plastic mass that can be molded into virtually any shape, but as the material hardens there is a reduction in volume or shrinkage. when shrinkage is restrained by contact with supporting soils, granular fill, adjoining structures, or reinforcement within the concrete, tensile stresses develop within the concrete section.

both methods will certainly lift and level your concrete however there are many advantages to using polyurethane over mudjacking. below are the main advantages and benefits to using polyurethane over mudjacking: longevity: since polyurethane is extremely lighter than mudjacking material the chance of re-settling is greatly reduced.
1.) condensation from the warm interior air hitting the cold concrete wall. this typically does not happen behind a well sealed wall (i.e. sheet rock), but it’s possible. 2.) vapor emissions through the concrete. this occurs when moisture moves through the concrete in vapor form, creating high humidity and saturation on the surface.
efflorescence will not only cause problems with a stained concrete floor, it can also delaminate tile and warp wood floors. the best approach would be to strip all the sealer and wax off the concrete. once the sealer and wax are removed, a moisture test should be conducted so you can get an idea of how much water is moving through the slab.

rule: concrete fasteners should not be set closer than 10-anchor diameters from each other. explanation: mechanical type concrete anchors exert outward pressure against the wall of the hole in concrete. this pressure goes out and up the length of the anchor forming what is commonly called a cone of concrete, as it is cone-shaped in appearance.

post-tensioned concrete is reinforced with a grid of high-strength sheathed steel tendons, or cables. while the concrete is curing, the cables are tensioned in both directions and held permanently under stress by anchoring them in a perimeter beam. this squeezing action keeps the concrete in compression, improving its tensile (or bending) strength.
