Six Reasons to Choose Skaw Pre-Cast
2. Skaw Pre-Cast manufactures WET CAST manhole risers.
WET CAST allows manufacturing of manhole risers in three foot sections. Three foot sections allow less joints
and less leaking and faster manhole-riser install time.
3. Skaw's tank selection.
A 2,000 gallon holding tank with a 28" inlet. Again, very useful for an area with a high water table or a hole
with a rock bottom. This tank is very heavy with a 4" thick floor. Other tanks manufactured exclusively at Skaw's
include a two chambered 1,000 gallon septic tank and a 1,250 gallon "two bedroom" combination tank. Either of
these two tanks would extend the life of a conventional septic system's drain field.
4. Skaw's one piece installation.
Ready for delivery is a 2,000 gallon holding tank. All tanks, unless specified by you, are installed in one
piece. This saves installation time and, more importantly, places leak warranties on Skaw's.
5. Skaw's premium quality products. Many tanks even include a fifth wall.
This 2,000 gallon holding tank is still in the mold used for casting. This tank is only 24 hours old and is still
"green". All of Skaw's tanks are dated and cure on our lot for at least 30 days before delivery. Please note the
inner wall cast in place for added strength. All of Skaw's tanks larger than 1,000 gallon
have this additional feature of a fifth wall. Also note the tar strip sealant already in place. The next step
of the manufacturing process is to install the cover. This pre-sealed tank saves time at the point of
6. Skaw's exceeds government code requirements.
Wisconsin code demands that concrete sewage tanks shall have a least 4 2" thick walls and floors. Tanks shall be
poured monolithic with at least 3,000 psi reinforced concrete.
Skaw's tanks have 3" thick walls and 3" or 4" thick floors of 4,000 psi concrete. We also include
the fifth inner wall. Compare the weight of a tank from Skaw's to any other manufacturer.
Skaw's tanks require less or no additional weight when anchoring is required.
