Savway Carton Forms

{Print This page}


1. Corrugated carton forms must be in a completely dry condition prior to placing concrete.

2. Should carton forms become wet, allow to dry thoroughly and test for strength before placing concrete as a wet/dry cycle reduces strength.

3. CAUTION!! High relative humidity can greatly effect the load bearing capacity of carton forms. Use of carton forms under high humidity conditions can result in excessive deflection and/or FAILURE of carton forms.

4. Corrugated carton forms must be stored off the ground and covered for protection from moisture immediately upon arrival, unless indoor storage is available.

5. If carton forms are covered with polyethylene, ventilation should be provided around the base of stacks to avoid moisture accumulation due to temperature change.

6. Individual component parts should be stacked separately by size. Failure to do so will result in costly delays and extra labor time in resorting and locating components.

7. WARNING!! (A) SHIPMENTS MADE BY COMMERCIAL CARRIER - Material must be counted and identified when unloading at job site. If material is found short or damaged, the consignee should file claim with carrier and shall take full responsibility for collecting from the carrier for any damages or shortages from Bill of Lading occurring in transit. (B) SHIPMENTS BY SELLERS TRUCK - Consignee must provide notice to seller immediately of damage or shortage of materials arising from error by seller.

8. Failure to notify seller immediately of any shortage or damage, due to seller's error, shall constitute waiver of any claim against seller on account of any damage or shortage.

9. Always place carton forms on a smooth dry bed with seam side down on grade, butted tightly end to end and/or side to side so displacement does not occur.

10. Carton forms should be free from any damage such as; punctures, scrapes, or moisture prior to placing concrete.

11. Carton forms require uniform support from sub-grade. Carton forms are not designed, nor should they be used to bridge trenches or open areas beneath carton forms, or as a permanent support for concrete.

12. Unnecessary traffic should be avoided on in-place carton forms.

13. We recommend the use of corrugated cover sheets on cartons under slab areas as a protective covering against necessary traffic while placing steel and during concrete placement.

14. We recommend cover sheets on beam forms where multiple forms are placed side by side to form wide beams.

15. Where carton forms are placed end to end, as is typical under grade beams, joints should be taped or coupled with same material carton forms are made of.

16. Trapezoidal carton forms should not be side loaded as skewing of form can occur causing undesirable formation of void space and/or collapse of carton form. Center load concrete on forms so it flows evenly into area to form legs.

17. The use of polyethylene covering is not recommended for carton forms in place except as a temporary protection from storms. When carton forms are covered tightly with poly it creates a "Hothouse" condition and may cause the carton form to draw moisture from the ground and form condensation, thereby saturating the carton form. THE USE OF POLYETHYLENE AS A COVER SHEET COULD RESULT IN SERIOUS DEFLECTION OR FAILURE OF THE CARTON FORMS.

18. Steel supporting chairs should have bases that will not puncture or damage carton forms. Where bolsters are used to support steel on carton forms, we recommend double cover sheets under bolsters.

19. WARNING!!! Vibrators MUST NOT come in contact with carton forms. This will cause puncture and subsequent failure of carton forms. THIS IS ONE OF THE MOST COMMON CAUSES OF CARTON FORM FAILURE.

20. Welding, burning or cutting near carton forms can cause fires or damage to forms. If this occurs carton forms should be replaced.

21. Corrugated carton forms are designed for forming on-grade or interior voids only, depending on design, and should only be used as left in-place forms. FORMS ARE NOT SUITABLE FOR USE AS OVERHEAD PANS.

22. Carton forms are manufactured from corrugated kraft material with liners and medium wax impregnated and bonded with resorcinol adhesive for moisture resistance.

23. Carton forms will withstand approximately 1000/PSF of a uniformly distributed load provided forms are in a completely dry condition, and no exterior damage to forms has occurred from abuse on the jobsite.

24. Failure to follow and abide by these recommendations relieves seller of all liability and could cause the user costly delays in time and material.

25. Contact our office for any assistance, questions, technical information or regarding carton forms for special applications and/or excessively heavy concrete loading. Savway Carton Forms liability is limited to the invoice price of our product.

26. Excessive cutting of carton forms can alter load bearing strength.
