TekFoam

Description

TekFoam cement is a non-combustible, void-filling, structural cementitious foam. Supplied as a powder, the cement forms a low-density foam (0.25 to 0.35 sg) when combined with the proper amount of air and water in the specially designed placer unit. Normally, four 45 lb bags/yd3 (5.23 bags/m3) are used. TekFoam mix is typically pumped 400 feet (121.9m) through a 1” (25.4mm) diameter hose, and farther through a larger diameter hose. The 20 psi (0.1379MPa) product begins to gel in minutes, forming a non-toxic, non-combustible product weighing approximately 540 lbs/ yd3 (320.4kg/ m3), and because of its rapid strength gain, is firm enough to walk on in 30 to 60 minutes. Consult your local Minova representative for additional application information.

Advantages

  • Fast – Pumping rate of over 100yds3 (76.46m3) per shift is possible; convenient one bag blend 
  • Simple – Placer unit meters in proper amounts of air and water while pumping the foam to the site 
  • High Yield – Less material to handle; four 45lb (20.41kg) bags will yield 1yd3 (0.76m3 ) - the result is less costly than typical foamed cements 
  • Safety – Roof falls and cavities can be supported safely; low causticity absolutely minimizes the possibility of cement burns
