We recognize that no business wants to be known as the one with the unsafe parking structure. When you need to ensure that your concrete structure remains in safe condition, we’re always ready to help you make the necessary concrete repairs.

Cracks in concrete slabs can pose a tripping hazard. If there is a height variance of 1/8 or more on either side of a crack, some type of repair is needed. The exact extent of repair will depend on the severity of the problem.

A modern construction wonder, the Hoover Dam was built in 1935 and used some 3,250,000 yards of concrete. Nearby dam-related structures and the dam power plant took another 1,110,000 yards to complete.

Ordering and delivery of concrete requires close coordination. Wet concrete is a perishable product and can only sit in the mixing truck for so long before it starts to deteriorate. Make sure your crew is ready to receive the product when it arrives.

Air-entrained concrete has microscopic air cells injected into the concrete to let concrete expand and contract easier through thawing cycles. This substance helps resist damage caused by weather and chemicals.

Concrete today is made up of Portland cement, a combination of limestone, calcium, aluminum, iron, silicone, and other minerals, which is both fine and coarse. Sand, water, and chemical admixtures are added to enable the concrete to harden and set properly.

In areas with ice and snow, avoid using de-icers, especially with new concrete. De-icers contain chemicals that can deteriorate concrete. Shoveling is often the best option, but, if you need to put down something, sand is your safe bet.

Did you know that ancient concrete builders, like the Bedouins, used groundwater to harden their early concrete mixtures? In fact, it was groundwater seeping through silica that transformed this silica into a pozzolan material, allowing for some of the earliest concrete to be created.

The performance of concrete buildings is superior to many other building materials. In fact, concrete offers superior acoustic insulation, fire resistance, vibration control, thermal efficiency, and overall durability.

Concrete has a very high compressive strength that can have added tensile strength when reinforced materials such as steel are added. In fact, the concrete that Romans used was as strong in compressive tests as modern concrete is, but it lacked tensile strength that new reinforced concrete has developed.

Care to guess the location of the oldest known natural concrete outcropping? We'll give you a little hint: it's been dated at 12 million years old. If you guessed Israel, you're right.
