How We Work

Working closely with the client throughout the project, we aim to establish a smooth, efficient and timely result for all concerned.

Construction stages

After the initial site assessment, we begin work on the site.

Step 1

Mark out and stake the extent of the floor

Step 2

Excavate the floor area plus 600mm beyond to facilitate back-filling to the perimeter units

Step 3

Lay 150mm of compacted hardcore and 50mm of pea gravel

Step 4

Fine-tune the pea gravel with a laser and place corner units and check the diagonals. Use string to mark out the long floor edges

Step 5

Complete the perimeter and fix units together. Then add and pin the layers of EPS 1 to 3

Step 6

Lay the DPM, rebar and mesh double check all dimensions and then pour the footings and slab

Step 7

Power float the finished slab as necessary
