PAVED SURFACES

Vertical Installation

When trenching is required, vertical installations take best advantage of Multi-Flow’s narrow profile.

However, in synthetic turf settings, a nearly impermeable clay base is established and select, porous fill is placed over it. Laying Multi-Flow directly on the dense clay base locates it where the water accumulates. This eliminates the need for trenching. Whether it is new natural turf field construction or the renovation of an existing field, Multi-Flow is a wise choice because:

Preferred Method – Rock Wheel Trencher

When soil exhibits sufficient cohesion, a rock wheel trench is an excellent way to excavate a 4 to 6 inch wide trench through the pavement and base materials to the specified depth.

This Rock Wheel Trencher method results in:
  •  less surface scarring
  •  less backfill
Alternate Method – Chain Trencher
  • When the base aggregate is loose or less compacted,a chain trencher is a good choice.
  •  Saw cut or disc cut to provide a uniform edge.
  • Remove the excavated pavement from the site.
  • Use a chain trencher to form a 4 to 6-inch trench to the specified depth.

Connection Of Collection System To Transport System
  1. Preferred Method
    • Locating the transport system below the collector system increase flow performance and reduce the risk of rehydration of low-lying areas. When using this preffered method, Multi-Flow Multi-Purpose connectors’ outlet the Multi-Flow Collectors. This preferred method only works when the elevation of the outlets allow for it.
  2. Alternative Method
    • If the site includes elevation constraints, the transport system can be located level with the bottom of the collector system.
    • When the transport system is located at the same level as the bottom of the collector system, end outlets or side outlets are used to outlet the Multi-Flow collectors.
  3. Either Methods—the geotextile filter should be securely taped to all connectors with wide pipe tape. This assures that debris will not infiltrate behind the fabric at these transition points..
6Resurfacing 673x1024
  1. Select, washed, very coarse sand for backfill.
  2.  Position Multi-Flow in the center of the trench and assure that backfill material extends from the bottom to the top of the trench on both sides of the product.
  3. Saturation of the previously backfilled trench is the preferred method to achieve consolidation. A 1-inch, low pressure stream of water applied to the top of the backfilled trench is adequate in most situations.

Replace pavement after consolidation is complete. It should exceed the thickness of surrounding pavement.
