Grade beam are easily formed using STAY-FORM® and rebar or lumber as bracing. Some contractors prefer to backfill 75 to 90 percent up the grade beam prior to the concrete pour in order to minimize the required bracing. Backfilling acts as the bracing which will stop the formwork from spreading during the pour.
Attaching with tie wire around the STAY-FORM® ribs and rebar or lumber makes installation easy.
Since the STAY-FORM® is not stripped, the excavation required is less than what would be needed using conventional formwork.
Some contractors use STAY-FORM® to hold the surrounding soil from falling in on the grade beam excavation and reinforcing steel.
