Fill – It’s quite possible that we were the first
ones to ever refer to this product by this name. Many years ago,
Harmony Sand & Gravel created a custom blend to satisfy the
needs of an engineering firm in Hunterdon County.
select fill is used on most septic system installations and provides
just the right amount of percolation. Since there is no one
specification to meet the needs of all septic systems, we custom
blend our product. This allows us to meet the exact requirements of
the individual situation, pursuant to the specifications that local
Townships engineer provides. Daily testing is performed by our
laboratory and these results are confirmed by an independent,
outside testing laboratory on a frequent basis. The customer is
provided with a copy of the laboratory certification.
townships specifications are on file and we are in daily contact
with many engineers. Our product is widely accepted because of it’s
quality and the service that comes along with it. The good news is
that you can afford to do the job the right way, the first time, and
at no more cost that if a lesser product had been used. Why take a
chance? The breakdown, removal and replacement of a failed system
can be extremely expensive. Often, it is many times the cost of a
job done right the first time around.
there are a few contractors that screen gravel direct out of the
bank and sell it by the yard (estimated). We could do the exact same
thing. But the problem is there is no way to control the quality
since the constituent particles sizes vary constantly in the face of
the gravel deposit.
only way to have control is to process the material through a wet
wash system, separate the material and classify with the exact
specification for the individual job requirements. This is the way
Harmony Sand & Gravel continue to do it and that is why we can
guarantee our product to meet specification.
Mounds – Elevated sand mounds are constructed using a
similar blended material and this material is also referred to as
Beds – Our #57 (3/4 inch) 100 percent crushed and
