The 10-to 12-year-old riders were being treated at a local hospital.
The "Super Spiral" waterslide accident occurred during Children's Day when joints holding segments of the popular ride collapsed.
Seven young riders fell through the damaged slide, according to company executive.
It is the second time in less than four months that the amusement park has experienced significant safety failures.
Siam Park managing director Wuthichai Luengamornlert said the "Super Spiral," a water slide three-stories high, had broken at the 2.5 metre level and that in addition aged 10-12 riding from the top of the water channel fell from the broken joint.
Most of the 28 injured childred suffered head injuries, with some broken limbs and bruises.
Four children remain in critical condition.
Mr. Wuthichai said Siam Park accepts responsibility for the accident and pledged to cover all treatment expenses.
Siam Park staff drained the water from the ride to facilitate a police investigation to inspect and determine the cause of the accident, he said.
The Super Spiral was installed and in service for some 20 years, he said, adding that the Siam Park bought it from a company in Canada.
Mr. Wuthichai said he believed that the Super Spiral was up to standard and has a 30 year life, but further investigation is needed to find the cause of the breakage.
In October last year, Siam Park hit headlines when a 35-year-old Thai woman died and five others were injured when a ride called the Indiana Log malfunctioned.
