How long will it last?

 Longevity depends upon the amount of use and force a PercoaTM slab receives. For example, a sidewalk will last longer than a roadway. PercoaTM is designed to have a lifespan of 15 to 30 years.

 What about freeze/thaw conditions?

 Pervious concrete has been placed in freeze-thaw climates for over 15 years. 
Successful applications of pervious concrete in freeze-thaw environments have 
two common design features-- the cement paste is air-entrained, and the 
pervious concrete is placed on 6–12 inches of drainable aggregate base (¾” or 
larger clean gravel). 

 Is it strong? (Compared to regular concrete)

 It is possible to achieve pervious concrete compressive strengths of 3000 to 4000 psi and flexural strengths of 500 to 600 psi, which are on par with conventional concrete. With the use of admixtures, today's pervious concrete mixes can be made with less water, which improves strength and durability. Also, better placement methods have resulted in tighter pavements that maintain point-to-point contact of all the aggregates while providing the necessary void content.

 Will it clog?

 Clogging problems are mainly an issue of design. If a natural area with grass or exposed soil is allowed to drain stormwater across a pervious concrete pavement, fine material can be introduced into the system causing localized clogging. Vegetative matter can collect on the surface of the Percoa  Slabs  causing some clogging, but routine sweeping or vacuuming will restore porosity. Studies have been conducted that indicate pressure washing will restore the porosity of clogged PercoaTM to nearly new conditions. 

 What is the maintenance?

 PercoaTM Slabs function well with little or no maintenance. Maintenance of PercoaTM consists primarily of prevention of clogging of the void structure. In preparing the site prior to construction, drainage of surrounding landscaping should be designed to prevent flow of materials onto pavement surfaces. Soil, rocks, leaves, and other debris may infiltrate the voids and hinder the flow of water, decreasing the utility of the pavement. Landscaping materials such as mulch, sand, and topsoil should not be allowed on the concrete, even temporarily. 
     Vacuuming annually or more often may be necessary to remove debris from the surface of the PercoaTM . Other cleaning options may include power blowing and pressure washing. Pressure washing of a clogged PercoaTM has restored 80% to 90% of the permeability in some cases.
