Sub Base Levelling.

Nationwide Concrete Flooring contractors laser controlled sub base preparation service, installation of the final layer of sub base utilising our laser guided sub base leveller.

This equipment uses the very latest in laser technology in order to achieve extremely tight tolerances and achieve vast daily outputs.The word ‘subgrade’ refers to the soil below the sub base. The sub base is the finely graded completable material between the subgrade and the concrete.

The sub base is a critical part of the construction process as this provides a working platform for construction activity and is used to transmit the load from the floor slab to the subgrade.Sub base levelling equipment used by concrete flooring contractors based in Howden near York in Yorkshire.Our experienced workforce can achieve tolerances of at least plus or minus 5mm from the overall datum using this laser controlled machinery. This not only minimises any potential waste of ready mixed concrete but also provides an excellent working platform during the concrete process. A level sub base enhances the long term performance of the concrete floor slab as the concrete can shrink more evenly without restraint. This reduces the chance of shrinkage cracking occurring over the life span of the concrete floor slab.The settlement and differential settlement of concrete slabs is a serious problem, and although they reflect on concrete, they aren’t caused by the concrete. They stem from failures of the subgrade or the sub base. Installing sub base properly is just as important as placing and finishing concrete and using the right mix design.

The laser guided sub base levelling and preparation machinery can also be used to grade the final layer of stone material for external slabs as well as internal floors. Nationwide Concrete Flooring supervisors set the laser equipment to work on straight grade falls so that the external yard will still allow surface water to reach the perimeter and or the drainage systems installed.The gradient fall required is fixed into the lasers and the sub base machinery still works in the same manner and with the same accuracy as with a flat internal floor slab. The machinery will also work well with a crushed recycled concrete material providing adequate fines content to allow binding during compaction. Depths of up to 100mm of recycled concrete can be laid in one pass which allows the levelling team to comfortably achieve 1,500m2 of area per day.

Testimonials.

“The work was fairly complex with some 2000 holes in the slab to be repaired, this required the holes being drilled out and then bolts reduced in length or removed, the holes were then filled with resin compound and ground down to the correct level. The work force on site were polite punctual and worked in a very clean and efficient manner, the attention to quality and health and safety were excellent, and the client was pleased with the end product. I would not hesitate to use Nationwide Diamond Group in the future.”
