TEKFOAM

TekFoam is a non-combustible, void-filling, structural cement foam.

TekFoam is a non-combustible, void-filling, structural cement 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 Tekplacer unit.

TekFoam mix is typically pumped 400 feet (121.9m) through a 1” (25.4mm) diameter hose, 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).  Because of its rapid strength gain, the foam material is firm enough to walk on in 30 to 60 minutes.

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

GeoFoam

GeoFoam is flame-resistant easily cuttable by tunnel boring machines when cured and has a low exothermic temperature making it safer for installers to use and the environment.

It is designed for the immediate stabilization of unconsolidated geological formations during tunneling, drilling, mining and other civil engineering projects.

After mixing, the resin quickly starts foaming-up within seconds forming a strong lightweight foam. Common uses include structural support in tunnelling and for the lifting of roadways or slabs.

TEKCRIB SUPPORT SYSTEM

Cylindrical bags, 27” or 30” diameter, are secured to the mine roof and are subsequently filled with a foamed cement.

The installation of the TekCrib system is accomplished by using the Minova TekPlacer unit, specially designed to combine the TekCrib powder with air and water, producing a cementitious foam.

The foam is typically pumped a distance of 1,000 ft., although much longer distances are possible, especially when pumping down surface boreholes. The mix begins to gel within minutes of discharge and cures to a final strength, ranging from approximately 400-800 psi.
