The process of raising sunken concrete slabs through the use of hydraulic pressure injection where a grout, or other base material, creates a new sub-base by filling voids beneath concrete slabs and hydraulically raising the sunken slab back to grade
Environmentally responsible application
Reuse existing slabs
Limestone material is natural, non-toxic

Waste

5. Carbon footprint - effect you have on climate in terms
of the total amount of greenhouse gases you produce
throughout your life
Burning fossil fuels for electricity, heating and
transportation etc.
Average American is responsible for 20 tons of carbon
dioxide emissions each year
Far greater per capita number than that of any other
industrialized country
US accounts for more than 20% of the world's total
greenhouse gas emissions

6. Carbon dioxide (CO2) has accumulated the most in
the atmosphere and is presently having the greatest
cumulative warming effect on our planet
CO2 is 85% of all worldwide emissions
Other gases include: Methane, nitrous oxide, CFCs, tropospheric
ozone
CO2 in atmosphere increased 30% since pre-industrial
times
Human sources of CO2 primarily includes burning of
fossil fuels (coal, oil, and natural gas) & deforestation
Directly affecting climate change and energy

9. Cement is an ingredient of concrete
Four elements used for manufacture: calcium, silicon,
aluminum, and iron
Concrete includes cement, water, sand, and gravel or
crushed stone
Cement is the “glue” that holds the mix together
Cement comprises only a portion of concrete

11. Concrete is the most widely used building
material on the planet
Second most used material in the world behind water
Easy-to-use and versatile
Abundant and readily available
Cement is a significant contributor to worldwide
GHG at almost 4% of total and 5% of total CO2
emissions
Top 12 cement-producing companies = 81% of
world total
China largest = 43% of world total

range of 50 to 100 years

13. Use “green” building materials whenever possible
Examine your exterior drainage regularly and
maintain to ensure water is directed away from
foundations and concrete areas
Caulk and seal all joints where water could enter
Consider concrete leveling as a preventative option
to fill voids or to raise sunken slabs
Consider re-surfacing as an option to improve
concrete surfaces
14. Increased technology allows for “green” building products
Leadership in Energy and Environmental Design (LEED):
Developing “Green Building” standard
Building design and development certification program to
measure: Sustainability, Waste efficiency, Energy,
Atmosphere, Materials, Resources, Innovation, Design
Demonstrate the efficient use of energy, water and materials
Limit impact on outdoor environment
Provide a healthier indoor environment
Government, business quickly adapting
15. Greenhouse Gas Protocol
An accounting tool for quantifying emissions for
businesses
The 2030 Blueprint
Green building rating systems, models such as Building
for Environmental and Economic Sustainability (BEES)
EPA Energy Star
Programs that focus only on recycled content or
renewable resources
Cementitious materials
16. Reduce downtime ~ same day use of slabs
Extend life of existing slabs
Save 50% to 70% versus the cost of replacement
