Sub Base Preparation, Grading and Compacting
sub-base-compact-leveller with laser-level control
Nationwide Concrete Flooring carries out the final grading and compacting of the sub base layer underneath the concrete floor slab using the laser guiding equipment.
The sub base compact leveller works in a similar manner to the concrete laser screed.Once the datum level and set the laser receivers moves the machine up and down to form a very accurate sub base level tolerances.
This not only minimises any potential waste of ready mixed concrete but also provided an excellent working platform during the concrete process. Using this laser controlled machinery we can achieve tolerances of at least plus or minus 10mm from overall datum.

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.
