Typically, between 15% and 25% voids are achieved in the hardened concrete, and flow rates for water through pervious concrete are typically around 480 in./hr (0.34 cm/s, which is 5 gal/ft²/ min or 200 L/m²/min), although they can be much higher.
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.
Is there a permeable concrete?

How thick is Permeable concrete?
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?
Essentially, pervious concrete is a structural concrete pavement with a large volume (15 to 35 percent) of interconnected voids. Like conventional concrete, its made from a mixture of cement, coarse aggregates, and water.
Is sand and cement permeable?
These materials are, in some cases, laid onto a mortar, either a standard sand/cement mortar, a coarser grit/cement mortar or, more correctly, a highly permeable grit-based mortar. Most concretes and stones are slightly permeable – that’s why they look damp long after the rain has stopped.
Can you lay slabs on building sand and cement?
Don’t lay paving on building sand
Building sand is not used for the laying of block paving or paving slabs unless it is combined with cement and even this mixture can be too soft to lay paving slabs upon. This is because of the fine nature of the sand.
Is mortar water permeable?
The highly water permeable pavement jointing mortars allow rainwater to drain away quickly, which communities count as surfaces that are not sealed and thus contribute to environment protection.
Can I lay slabs without cement?
How to lay paving slabs on sand. An alternate way of laying paving slabs is to use a sand and gravel sub-base. Sand is affordable and easier to use than concrete while still making a secure base.
Can you lay a patio straight into soil?
While it is possible to lay paving slabs on soil, it is not generally advised. The durability of any paving with a soil base can depend on many factors, including: Type of soil: Heavy clay soil will be far more durable and less likely to be compromised by British weather conditions.
Can you lay paving slabs on a dry mix?
I’ve just laid my patio on to a dry mix – works quite well. The ratio can be as low as 1:10 (1 cement, 10 sharp sand), or as high as 1:3, depending on the amount of foot traffic you expect, and what the sub base is like.
