This is TURFSTONE...
A multipurpose paving stone. Originally designed to help in erosion control by holding the earth on the steep slopes, embankments, and other unstable areas. However, in no time landscape architects were finding a myriad of other uses for TURFSTONE and were applying them in versatile and attractive ways. Soon the public began to notice TURFSTONE in use and liked what they saw. The result was a boom in TURFSTONE's use. In Europe, where TURFSTONE was first manufactured, the system proved to be so successful that by 1975 more than 52 million square feet of the paving stones had been sold. Of course, the introduction of TURFSTONE to Utah by Lehi Block has been much more recent; but the acceptance by the public has been no less dramatic.

What makes the TURFSTONE such a popular notion? In a word -- versatility. TURFSTONE not only does the job for which they were designed, controlling erosion, better than anything else anyone has ever devised. It also has nearly unlimited uses for a variety of other applications. As usual, the applications of such a versatile product like TURFSTONE are limited only by the individual imagination.

The Following is a partial list: Erosion control on embankment, earth berms, swale for open ditches and flood-way districts. Combating soil erosion by using as revetments for lake banks, inland rivers, dykes and creek slopes. Private driveways and roads. Rest areas along highways. City, County, State, and Federal recreation parks. Golf cart paths an parking areas. Cycle paths. Access routes for emergency vehicles. Cross-overs for emergency vehicles on Interstate Highways. Campsite and resort areas. Parking areas around school and College campuses, shopping centers, office complexes, apartments, etc. 1001 individual home uses.

Installation of TURFSTONE

A satisfactory foundation is an essential prerequisite for the durability of a TURFSTONE surface. Unfortunately, there are no specific guidelines because different ground and drainage conditions have to be considered in each instance. Also, traffic requirements play an important role.

The two major factors that govern the installation of TURFSTONE are: The bearing capacity of the existing sub-soil and the type of traffic to which it would be subjected.

Sub-Soil: Unsuitable sub-soil should be excavated and the back-fill be compacted with a vibrating compactor.

Sub-Base: Use 3" to 16" of 3/4" or 5/8" crusher run which should be compacted with a vibrating compactor. The amount of crushed material should be determined by the bearing capacity of the existing Sub-soil.

Example: For domestic and commercial areas use 3 to 10 inches of crushed stone depending on the bearing capacity of the existing sub-soil. For heavy duty and industrial areas use 10 to 16 inches of crushed stone; again, depending on the bearing capacity of the existing sub-soil.

In some situations, the bearing capacity of the existing sub-soil is stable enough to support certain types of traffic without the use of crushed material.

Leveling Bed: A 2" layer of graded sand, leveled. DO NOT compact.

Installation of TURFSTONE:The TURFSTONE units should be placed over the sand.

In areas where the TURFSTONE is applied on steep embankments, it is recommended that each paving stone be secured with a 24" stake after it is installed.

So you have to install pipelines under and existing TURFSTONE surface! No problem!
