Permaloc's Permeable Proved by Lab Results

This diagram illustrates a typical permeable installation utilizing a geogrid captured between Permaloc's aluminum edging and capture plate.

Results are in from an independent test of the new patented permeable paver edge restraint system developed by Permaloc Corp. The testing has proven that Permaloc's system increases its holding strength when the pavers are loaded.

Independent geotechnical testing showed the patented PICP edge restraint system significantly exceeds existing ICPI specification for edging installed on traditional compacted base material.

For comparative results, testing was performed on the new system, as well as a traditional system spiked into a compacted base. Over the course of the load testing, the new permeable system significantly outperformed the traditional system, measuring five times less displacement.

The tested restraint system is composed of an ''L'' shaped aluminum paver edging and a unique corrugated aluminum capture plate combined with the specified geogrid, permeable paver and base materials. The geogrid textile is placed between the base course and the setting course of chipstone.

Stainless steel, self-tapping screws are used to capture the geogrid material between the edging and the corrugated capture plate, restricting horizontal displacement to less than 2 mm under repetitive static loads of 130 kN.

Embedding the common bi- or tri-directional geogrid textile into the stone base creates an integrated friction bound plane, which securely anchors the entire system, producing exceptional pull out resistance.

As a load is applied to the pavers, the downward pressure moves to the geogrid, thus drawing the edging in tighter against the pavers, increasing the strength of the edging.
