TekSeal HD is a high density cement foam used for void filling where very rapid development of strength is required. Typical applications of Tekseal™ HD include void-filling during reef pillar extraction and construction of explosion - proof stoppings or barriers.
Tekseal™ HD is a single component cement foam that is supplied as a powder which forms cement foam on mixing with water in a purpose designed placer.
High yield improves material handling logistics and cost
Typically, only 3 people needed per crew
Non-flammable, non-toxic, cement based
Rapid placement reduces man shifts - typically 50 cubic metres void filled per shift
Remote placement can take place up to 100 m from machine
Maximum pump life is approximately 15 minutes with water at 25°C
Rate of set and strength development are affected by temperature and the water / solids ratio used
Compressive strength of 1.5 MPa after 28 days of curing
Packed in 25 kg bags
Bags may also be grouped into 1-tonne bulk bags upon request
It is supplied in 25 kg lined woven polypropylene bags and forms cement foam on mixing with water in a purpose designed placer.
