Speedcrete ups screed speed

The revolution in concrete screeding methods takes a giant step forward with the introduction into the UK of the Vibra Strike multi-purpose screeding machine. At least that is what Speedcrete CP of Southampton would have you believe.

The Vibra Strike is light, with the base unit weighing only 9.5kg and with the 3.1m floater bar, the weight goes up to 16kg. A 1.12kW 30cc Robin supplies the power via a flexible drive to the horizontally mounted vibrator.

The move towards flood pouring, or wet screeding methods is rapidly gathering momentum. The laying in of traditional screed rails is not necessary as the area can be flood poured, set in 2-3mm high to allow for settlement, then trimmed level by laser spotting.

Versatility of the unit is enhanced by adding four different head types, a floater for wet screeding, curl edge for form to form or screed pipe performance, a magnesium straight edge and finally, a 2in X 4in timber rail. Floater bars are available in three lengths of 2.44m, 3.1m and 3.6m.

Using the curl edge bar, which comes in lengths up to 4.3m, the machine may be used for standard form to form screeding, or in conjunction with the usual screed pipe. The curl edge has a concave cutting edge that slices into the concrete to reduce rollback and provide a smooth finished surface.

For wider bay widths up to 8.2m, two Vibra Strikes can be attached to a single beam. Speedcrete says the unit needs less than five minutes to set up and production rates are virtually doubled. The unit moves easily round obstructions due to its weight and the horizontal vibrations reduce the possibility of honeycombing around edge forms.

Also important is the machine's ability to screed concrete as well as sub base, blinding and even gravel. A number of units have been sold, the first is working on a large Tesco site in Southampton. Interestingly, Ermin Plant is the first plant hirer to acquire a unit which is working satisfactorily in the Gloucester area.
