Stampco Concrete Inc - Beware of Stampco Concrete Inc. in Henderson NV
Posted on Monday, February 25th, 2008 at 5:14pm CST by Paul H.
Product: Stamped Concrete Driveway
Company: Stampco Concrete Inc
We contracted Stampco to do our driveway, sidewalk and entryway. We gave them the required deposit to start the job. Stampco damaged our planters,outdoor lighting,sprinkler pipes,plants,front door and house stucco. We have pictures and notice of corrections from the NV State Contractors Board. They also left a bootprint in the freshly poured entry way concrete and denied doing so. They were paid in full and Stampco has made no effort to stand behind their work.
The owner of the company Owen Ondrisko responded with. "we are not responsible for damage to your fucking house, read the god dam contract." Ondrisko and his brother used profanity and yelled at my wife and I on 2-06-07 after being confronted with the issues of construction defects and damage to our house. They called the Henderson Police and filed a bogus report against us maliciously
Our driveway is cracking and lifting due to shoddy construction. I have posted a scientific report from a P.H.D.'s findings of our distressed Driveway.
Stampco has made no effort to remedy this situation. I have asked for our nmoney back and have not heard from Mr. Ondrisko as of 2-25-08.
We have not been treated fairly, honestly and ethically and have been a victim of shoddy construction work,deception and poor business practices.
Beware of Stampco. Stampco surrended their license voluntarily and were issued another one with a different name.
Summary from P.H.D.
This letter is written to provide you with a summary of our investigation of the distressed driveway at the subject site. The driveway is approximately 35 feet x 35 feet in
dimensions. The defects associated with the driveway are listed below:
Concrete curling. The corners and edges of the concrete panels are curling up.
Up to ??? inch differential elevation along a 10 foot straight edge. At the edge of
the panels there is up to ??? inch elevation difference between the edge of the
concrete panels and the surrounding concrete border strips.
??? Thickness of the concrete slab was inadequate. Five concrete cores were taken in
the driveway. The concrete slab thickness varied between 1?? inches to 4??
??? Concrete slab is cracked and the cracking is continuing. When the concrete curls
it leaves a void beneath the curled area. The concrete in this area becomes
cracked when an automobile drives over the void area.
??? Petrographic Analysis of the concrete cores showed the following:
o There was differential hydration of the concrete from top to bottom. This
was most evident in the upper portion of the slab. The slab was poured
under very cold conditions.
o Freeze-thaw damage included some cracks down to ?? inch beneath the top
surfaces and reduced cementitious hydration in the uppermost concretes.
No air entrainment was found in the concrete. Air entrainment is
recommended when pouring under freezing conditions.
o Cracks and relatively soft paste makes the driveway surface potentially
susceptible to scaling especially with continued wear of the clear coating.
o The driveway was poured at too high of water/cement ratio. Interpreted
overall water to cement ratio was 0.55 to 0.60 based on comparison of
observed paste properties to laboratory reference samples of similar type
and age. The uppermost ??? inch to ?? inch of each sampled concrete had
an interpreted water to cement ratio slightly in excess of 0.60. When
concrete is exposed to freeze-thaw then the water to cement ratio should
not be greater than 0.45.
