EZ Concrete Forming manufactures a technologically advanced patent pending stay-in-place concrete forming system called the EZ Concrete Forming System. It is intended to bring the quality and durability of concrete construction to a wide range of applications where concrete has not been previously considered cost effective. This will allow builders and developers to provide their customers with a superior product at a competitive cost when compared to a product of lower durability. It will also help reduce the labour in some parts of the building process, and allow more efficient use of workers with lower levels of skill.
1. Pour concrete slab or footing.
2. Construct scaffolding and shoring
3. Mark concrete every 12", starting with the inside corner, in order to ensure correct placement and alignment or formwork.
Be sure to leave a minimum of a 12" gap between corner and supports.
4. Assemble corner using steps 1 through 8 (found in the assembly manual) and stabilize corner steel with enough connectors for every 6" of steel.
5. Continue assembling the wall. Each panel joint contains 1/32" play to allow for proper alignment with placement markings.
6. Support the top of the completed formwork with 2x4 and 1x2 'straps' in 4' to 5' lengths. At the beginning of the wall, tie together at the corners and later replace with 10' lengths.
7. Once 19' of wall has been completed, slide up the corner panel and slide steel into formwork at an interval determined by the project engineer.
8. Slide up panels in order to tie vertical steel at an interval determined by the project engineer.
9. Continue by constructing all other walls to finish the enclosure by following this procedure.
10. Be sure to place any electrical conduits, ducts anchors or insulation as required by the project engineer before the pouring of concrete.
11. Pour concrete, with a 3" slump, plasticizer, and 3/8" aggregate, into forms using the following technique:
Pour concrete starting with one corner and continuously pour along the length of one wall to set the bottom of the forms to a 1' to 2' depth. return to the original corner in no more than 30 minutes with a further 3' to 4'. Every 30 minutes you can pour another 4' or 6'. Be sure to vibrate using a small diameter head vibrator after every pass using a standard technique. Over vibration is not advisable. Don't forget to straigten the wall soon after pouring before the concrete hardens. If you are constructing a liquid containment tank, you must arrange for a continuous pour and be particularly attentive not to allow cold joints to form.

Benfits of the EZ Forming System
According to the U.S. Green Building Council (USGBC) in their 2007 report on PVC in Green Buildings, "PVC is as acceptable as competing materials in products for green buildings and discouraging the use of PVC 'could steer designers to use materials which perform worse over their life cycles'". The LEED rating system rewards projects for the use or avoidance of certain materials. Embeded components used in the EZ Concrete Forming system are composed of 50-100% recycled material depending on the availability of good quality PVC. This could improve the LEED rating of projects built with EZ Form.
