Perf Weeping Tile 6" x 100' w/sock


Polytubes Perforated Corrugated High Density Polyethylene Tubing with Sock Filter For Subdrainage Applications. The Sock filter is a seamless, knitted polyester filter that is used to prevent blockage of the pipe in sandy or silty soils. In fine sandy and silty soils, unprotected drainage tubing is apt to be blocked by a build-up of soil particles in the drains leading to failure of art or all of the system. Whenever subsurface drainage tubing is installed in soils featuring small particle sizes, filtered tubing should be used.

  • The Tubing is corrugated for maximum strength, yet it is light in weight and flexible for ease of handling and installation.It can be cut to size on the spot for a custom fit every time.
  • Once installed, it resists both corrosion and abrasion in most applications for dependable performance.
  • The corrugated design adds strength to resists the pressure of burial in the ground. Extra durability is provided by the material itself. The plastic is inert so it is practically indestructible, even in corrosive environments.
  • Tubing is available as standard non-perforated pipes, perforated pipes and perforated pipes with SOCK filter for areas where fine soils present a clogging problem.

Easy to Install: Lightweight and easy to carry. Saves time and labor.No special tools or fittings required, just cut to the required length.

Flexible: Shifts with the ground. No problems due to misalignment and clogging, because the tubing is so flexible. Big 'O' aligns itself which allows the system to continue to work efficiently

Strong-Tough-Durable: Won't crack or break under normal handling and installation procedures. Tough enough to withstand the heaviest loads.

Long Life: Will not deteriorate. Rust resistant. Not affected by acid soil content or other problem soils. Not affected by the freeze-thaw cycle.

The light weight and ease of handling and installation allows this tubing to be ideal for many applications including:

  • Underslab drainage
  • Downspout runoff
  • Interceptor drains
  • Retaining walls
  • Low spots
  • Pool drains

While filtered tubing is ideal for use in land drainage in sandy or silty soils, it also has many other applications in the land improvement industry including highway edge drainage, sports fields, golf courses, under sand traps, foundation drains, parking lots and airport runways.

Proper drainage is essential for successful landscaping, and a properly designed and installed Big 'O' drainage system helps ensure maximum use of the area by removing excess water and promoting overall heath of turf, trees and plants.

  1. Care during Installation: Care should be taken to prevent damage to the tubing during the backfilling operation. Avoid dropping large soil clods or rocks directly on the tubing. Heavy loads of all types should be avoided until the soil around the installation area is properly settled.
  2. Bedding: Tubing should be bedded in gravel or crushed stone. However, selected soil backfill material may also be used with satisfactory results. The bedding material should be placed around the tubing to a depth of at least 2" (50 mm) over the top of the tubing. When selected soil bedding material from the trench excavation is used, choose small loose particles of soil that will flow around the tubing and minimize soil settling. Avoid large rocks that may damage the tubing or large clods of soil that cause voids and subsequent excessive settling.
  3. Depth To Cover: If vehicular traffic is expected over tubing, there should be a minimum of 12" (305 mm) of cover over tubing if gravel bedding material is used, Typical recommended gravel material would be pea gravel, granular A stone or pit run course sand and gravel mixes.
  4. Proper Grades: The grade, or fall on which the tubing is laid is important in that reversals in grade will reduce the effectiveness of the system. Best drainage results are achieved with a continuous downhill fall, or grade, over the entire length of the drain line. A fall of 2" (50 mm) per 100ft (30.5m)of length is generally considered adequate, Greater fall will promote more rapid drainage.
  5. Proper Backfill Selection: Choose your materials according to application. If absorption and drainage are required, perforated tubing should be used. If tubing serves only to remove water away from an area ( such as downspout runoffs, etc.), non-perforated tubing is best because it will not dissipate water into the surrounding area. Non-perforated tubing should also be used if the line runs close to trees where root penetration may be a problem. If the soil being drained is sandy or silty, the Big 'O' "The Sock" filter should be used to prevent fines from entering and blocking the drainage line.

Tubing is manufactured from high density polyethylene resin which meets or exceeds the requirements of Type III, Category 4 or 5, Grade P33 or P34, Class C, as per ASTM D1248.

The nominal size of the pipe is based on the nominal inside diameter of the pipe. the tolerance on the specified inside diameter shall be +/-3%.

  • Nominal Diameter: 4" (100 mm) and 6" (150 mm)
  • Outside Diameter: 5" (120 mm) and 7" (180 mm)

Perforated Tubing with Sock Filter is Available in 4"x164'  4"x100'  4"x250' and 6"x100'

Drainage systems frequently fail in fine sand and coarse silt soils because particles enter drain lines in sufficient quantity to block the drains.

A filter is used to protect drainage tile and tubing from silt. It is a tough one piece knitted polyester envelope material that fits over the drainage tile and tubing like a sleeve.

The filter material is tough enough to resist tearing and damage in handling, shipping and installation. The filter material spans corrugations, perforations and joints to prevent sediment from entering and eventually blocking the pipe.Totally suspended colloidal particles pass through the filter and out of the drains with the water. Passage of very fine particles actually improves the system's efficiency by increasing the permeability of soil near the drain lines.

Test show, that the Big 'O' filter provides a more uniform mesh than spun/bonded materials, flow rates are higher, and the knitted polyester filter is more resilient to scuffing than other filters.
