     Corporation;

2.   Based on my knowledge, this annual report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements made, in light of the circumstances under which such
     statements were made, not misleading with respect to the period covered by
     this annual report;

3.   Based on my knowledge, the financial statements, and other financial
     information included in this annual report, fairly present in all material
     respects the financial condition, results of operations and cash flows of

4.   Dayton Superior Corporation's other certifying officer and I are
     responsible for establishing and maintaining disclosure controls and
     procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for
     Dayton Superior Corporation and we have:

          a.   designed such disclosure controls and procedures, or caused such
               disclosure controls and procedures to be designed under our
               supervision, to ensure that material information relating to
               Dayton Superior Corporation, including its consolidated
               subsidiaries, is made known to us by others within those
               entities, particularly during the period in which this annual
               report is being prepared;

          b.   evaluated the effectiveness of Dayton Superior Corporation's
               disclosure controls and procedures and presented in this report
               our conclusions about the effectiveness of the disclosure
               controls and procedures, as of the end of the period covered by
               this annual report based on such evaluation; and

          c.   disclosed in this annual report any change in Dayton Superior
               Corporation's internal control over financial reporting that
               occurred during Dayton Superior Corporation's most recent fiscal
               year that has materially affected, or is reasonably likely to
               materially affect, Dayton Superior Corporation's internal control
               over financial reporting; and

5.   Dayton Superior Corporation's other certifying officer and I have
     disclosed, based on our most recent evaluation of internal control over
     financial reporting, to Dayton Superior Corporation's auditors and the
     audit committee of Dayton Superior Corporation's board of directors:

          a.   all significant deficiencies and material weaknesses in the
               design or operation of internal control over financial reporting
               which are reasonably likely to adversely affect Dayton Superior
               Corporation's ability to record, process, summarize and report
               financial information; and

          b.   any fraud, whether or not material, that involves management or
               other employees who have a significant role in Dayton Superior
               Corporation's internal control over financial reporting.
