NEW PICTURES! Combating Soil Erosion

Pipe Drainage Drainage Pipe raked
Yards that are soggy and have soil erosion are never appreciated! For this homeowner Hendrickson Excavating installed N-12 pipe underground, taken out to daylight, to drain the water.

Pipe was covered with topsoil than the area was raked and seeded.

Pipe Drainage Hay Pipe Drainage Seeded
Now the water will drain, the grass will grow and it will shortly be a wonderful place to spend time together!

This is a septic repair that was required due to a failed inspection.

Septic Repair New Distribution Box
The failed portion of the system was the distribution box. The function of a distribution box is to equally distribute water to each lateral within the septic field. Photo shows the new distribution box reconnected to all piping. Upon completion all work is backfilled, raked and
grass seed is placed on the disturbed area.

Soil prep for construction of a 30'x30' building pad.

Stripping the ground New Surface
Stripping of vegetation and topsoil. 
Finished product. 30" fill on the low side using shale for fill material and crushed stone for the finished surface.

This was a septic system alteration on ground that was difficult to perk.

This type of system requires that the contractor have an advanced treatment
license issued through the National Environmental Health Association.

Tank is a Hoot Sand Filter Bed
Tank is a Hoot H600 ATU with two drip zones.

This is a sand filter bed with drip tubing installed. You can also see the corner of the 2nd bed in the picture.

Irrigation Beds

Gravel Driveway

Dirt Driveway GravelDriveway
Driveway graded and ready for stone. 
Finished gravel driveway. (Note: Stone looks "old
and dirty" when it's first applied due to the "stone
dust". Once it rains all the dust washes away and
the gravel looks clean.)

Backhoe Hammer Foundation Excavation
