Concrete is without question one of the strongest most versatile and long lasting construction materials ever invented. Really, not much has changed since the Romans built the Pantheon back in 128 AD.

But, that is all about to change. The trend toward sustainable construction has pushed the envelope in the area of concrete mix designs by introducing materials that are not only more green but that can create a more superior final product.

Global Green Concrete is an in-house division of Global Green Builders that specializes in providing both traditional concrete installation and Green alternatives. We have been in construction for more than 25 years and decided over the last several years to focus on structural concrete. More recently, we have re-tooled our structure and business strategy to promote the use of Green concrete that will in the near future become the standard for new concrete construction. It makes no sense not to consider these products since they often provide a real value engineering alternative on structural designs and are available today.


(Worlds Oldest Concrete Building)

What we offer:

As a Global Green Builder division, we have the resources and organization to operate more efficiently and at a lower cost structure than most competitors. Without a doubt, the key to our company is our expertise in Supervision which is the cornerstone of any successful project. Our

General Superintendent has over 35 years of experience in structural concrete.

We offer a full range of concrete services including:

  • Structural footings and slabs
  • Elevated and subterranean decks
  • Cast in place columns and walls
  • Shotcrete
  • Block Work
  • LEED certified
  • Design Build.

 

Turning Grey Concrete Green

Going Green does not need to be cost prohibitive to a project which is a common misperception. One of more promising products recently introduced is a product called I-Crete which has achieved amazing PSI strengths and is being used as a substitute for standard mix designs at a savings of 5% or more on material costs. Increased strength concrete will also show savings in steel reinforcement also. (See http://www.icrete.com/)

As mentioned before, sustainable construction infers that there is and must be an economic benefit to going green. LEED (Leadership in Energy and Environmental Design) is the most accepted organization for rating a buildings sustainability.

How Does Concrete Help Achieve LEED Certification?

Using concrete can help increase the number of points awarded to a building in the LEED system. The following table provides suggestions for earning LEED-NC v2.2 points through the use of cement and concrete products. The credit categories and the credit numbers are those in the LEED rating system. Points must be documented according to LEED procedures in order to be earned. The USGBC website, http://www.usgbc.org/, contains a downloadable letter template that greatly simplifies the documentation requirements for LEED v2.2. The potential available points that can be earned with the help of concrete range from 19 to 28.

Pervious Concrete: When it Rains, it Drains.


(Roman Walkway)

Pervious Concrete Pavement is one of the most exciting developments in Green concrete.


(Pervious Concrete)

Pervious concrete is a mix of course aggregate, cement, water and little to no sand. Also known as no-fines or porous concrete, this mixture creates an open-cell structure, allowing rain water to filter through to underlying soil. By modeling natural ground cover, pervious concrete is an excellent choice for stormwater management.

BENEFITS of Pervious Concrete

  • Reduces stormwater runoff

  • Eliminates the need for detention ponds and other costly storm water systems

  • Replenishes water tables and aquifers.

  • Allows for more efficient land development

  • Minimizes flash flooding and standing water

  • Prevents polluted water from entering our streams

  • Mitigates surface pollutants.

Pervious concrete puts rainwater back in the ground where it belongs. It allows 3-8 gallons of water per minute to pass through each square foot- accounting for far more than is generated during most rain events. While the pervious system is more costly than standard asphalt, it has a far better life cycle cost and more importantly it can eliminate the need for a costly storm water management system including catch basins, detention vaults, curb and gutter and underground piping which on one recent project saved an owner almost $260K (He paid $200k for the pervious concrete vs. $460K for the asphalt and storm system noted above).
