Permeable Pavers Role in LID: Water passes through the upper lever of the pavers to a sub-level infiltration basin. Storm water is therefore treated through filtration volatilization microbial activity storage and ion exchange. Water is filtered slowly and can be used on-site. Iniltration: There is some disagreement about how much water infiltrates through permeable pavers. The percentage of water that actually moves through the pavers must be figured considering the lifetime of the paver surface and the type of soil beneath the surface. For clean pavers free of dirt and soil a study has shown that water can move through permeable pavers at a rate of 3-4 inches per hour.
If you adhere a product to a surface that is cracked or will most likely crack (i.e. concrete) then that product since it is adhered to the surface beneath will also crack. A thin paver field is NOT adhered to the existing deck! The interlocking system that is utilized with a thin paver installation in conjunction with the joint sand produces a surface that can float on the deck beneath all the while staying even smooth and crack-less! I mentioned that the field is not adhered in the previous paragraph however there has to be interior and exterior edge restraints to keep the field from moving. The first step to installing pavers on your pool deck is to secure the interior of the paver field with coping which are the bull nose pieces set around the perimeter of the pool itself. The coping pieces are cemented to the deck and grouted.
Some producers of permeable pavers may suggest that the rate of water which passes through the pavers is much higher than this. Unreasonable claims of permeablity should be questioned. Exfiltration: Rainfall may exceed the exceed the infiltration rate of the soil below. For different densities of soil different exfiltration methods may be utilized in order to completely re-route water: Full exfiltration: An installation situation in which the sub-soil is anticipated to exfiltrate all of the rain fall without the assistance of additional drainage. Partial exfiltration: An installation situation in which the sub-soil is not anticipated to exfiltrate all of the rainfall in which case additional sub-surface drainage is utilized to re-sirect the water.
Let each contractor know you are obtaining multiple quotes. Set a deadline for receipt and grade them based on the initial meeting professionalism of the quotation price etc. Be sure to compare apples to apples; each paver driveway installer should be bidding on identical project specs using identical materials. Theres nothing better than word of mouth and testimonials but property owners need to be knowledgeable. Whether its making the first call or comparing the quotes received its up to the consumer to get the "talk around town."
