How much is Topmix permeable?
How much is Topmix permeable?
How much does Topmix Permeable concrete cost? Topmix Permeable concrete or similar types cost $8 to $16 per square foot installed.
Is there a permeable concrete?
Permeable concrete technology that provides the optimal solution for surface and storm water management. It naturally improves drainage through the unique design of the water management system.
How thick is permeable concrete?
5 to 8 inches
Materials specifications
Material | Specification |
---|---|
Pervious Concrete | Void content: 15% to 35 % Thickness: typically 5 to 8 inches |
Porous Asphalt | Void content: 16% to 20 % Thickness: minimum 2.5 inch surface |
What is permeable concrete made of?
Pervious concrete consists of cement, coarse aggregate (size should be 9.5 mm to 12.5 mm) and water with little to no fine aggregates. The addition of a small amount of sand will increase the strength. The mixture has a water-to-cement ratio of 0.28 to 0.40 with a void content of 15 to 25 percent.
How does permeable concrete work?
Pervious concrete is a special type of concrete with a high porosity, made from a mixture of cement, water, coarse aggregate and a minimal amount of fine aggregate (sand). Pervious concrete creates a porous medium, which allows water from precipitation and other sources to pass through and reach the underlying soil.
Is permeable concrete more expensive?
Over its lifetime, pervious concrete can be a much more inexpensive option than traditional concrete, even though the installation cost of pervious is typically higher than that of traditional concrete.
How strong is permeable concrete?
600–1,500 pounds per square inch
Pervious concrete has a common strength of 600–1,500 pounds per square inch (4.1–10.3 MPa) though strengths up to 4,000 psi (28 MPa) can be reached.
What is Topmix permeable concrete?
Topmix Permeable concrete, once laid down, has a surface that allows water to seep through it which helps prevent. Lafarge Tarmac claims that Topmix Permeable concrete not only prevents surface water flooding, but also checks the formation of puddles and help to reduce the heating of tarmac in hot weather.
What is permeable concrete driveway?
Permeable pavement is a pavement type with a porous surface that is composed of concrete, open pore pavers or asphalt with an underlying stone reservoir. Also considered as green pavement, it allows water to run through it rather than accumulate on it or run off of it.
How strong is Permeable concrete?
What is the biggest disadvantage of permeable concrete?
Disadvantages: Permeable paving is not ideal for high traffic/high speed areas because it has lower load-bearing capacity than conventional pavement. Nor should it be used on stormwater “hotspots” with high pollutant loads because stormwater cannot be pretreated prior to infiltration.
