Our yellow 1800 hole tubing is a new innovation for sandy-soils.  With 1800 fine pinholes per foot, this tubing has proven to be a very effective alternative to filter or sock tubing.  It provides maximum drainage without the additional cost of sock installation or risk of the sock tearing.  We guarantee this product to drain as well as filter-wrapped tubing, and not to fill with sand.  We have sold millions of feet of our 1800 hole sand tile under guarantee without one complaint.
