This standard applies to regular “thick” pavers, not the thin pavers that are used as an overlay on pool decks, patios and walkways. The standards for the manufacturing of concrete interlocking pavers are set forth in the ASTM C936 (American Society for Testing and Materials). Saying all pavers are the same is like saying that all sealers are created equal, which is far from true. Interlocking paver manufacturers offer a multitude of different colors and paver styles at varying price points. Concrete pavers across the country can be quite different depending on the materials that are used. With the rising demand for hardscape installations, the demand for sealing all these paver installations is on the rise as well. No other sealer company has recognized this issue, and they continue to recommend sealing the same way as in years past which only leads to frustration. The pavers being installed today are either more porous than in years past, or they are extremely dense, forcing the sealer contractors and DIYers to change as well. The paver manufacturing process has evolved over the years only to leave the old tried and true way of sealing pavers obsolete. You move on to the next job and repeat the exact same process. You pressure clean the pavers, re-sand the paver joints and then apply two coats of your favorite paver sealer and the job was complete. In years past, you could approach almost every sealer job the exact same way. Several fact sheets for permeable pavement provide overview information and information on design, construction and maintenance, and volume and pollutant removal.Anyone that has been in the paver sealing industry for any length of time can tell you the old ways of sealing pavers have come to an end.

Run-on from adjacent vegetated areas is generally not recommended and if it occurs, must be stabilized and not generate sediment as its transport accelerates permeable pavement surface clogging.Ĭaution: Sediment control (pretreatment) from adjacent impervious or vegetated contributing areas is HIGHLY RECOMMENDED to avoid clogging of the permeable pavement surface The capacity of the underlying reservoir limits the contributing area. Permeable pavement surfaces may accept runoff contributed by adjacent impervious areas such as driving lanes or rooftops. From a hydrologic perspective, permeable pavement is typically designed to manage rainfall landing directly on the permeable pavement surface. While design details vary, all permeable pavements have a similar structure, consisting of a surface pavement layer, an underlying stone aggregate reservoir layer, optional underdrains and geotextile over uncompacted soil subgrade. While permeable pavements can withstand truck loads, permeable pavement has not been proven in areas exposed to high repetitions of trucks or in high speed areas because its’ structural performance and surface stability have not yet been consistently demonstrated in such applications. Permeable pavements have been used for areas with light traffic at commercial and residential sites to replace traditional impervious surfaces in low-speed roads, alleys, parking lots, driveways, sidewalks, plazas, and patios. The most commonly used permeable pavement surfaces are pervious concrete, porous asphalt, and permeable interlocking concrete pavers (PICP). Permeable pavements allow stormwater runoff to filter through surface voids into an underlying stone reservoir for temporary storage and/or infiltration.
