Enhance your property by laying a new patio – part #4

First row of slates laid on compacted MoT Type 1

With most of the below-ground works finished it’s now time to start building the ground back up.
A green led laser level (more easily seen in daylight) was used to mark the highest point of the patio Then allowed for other factors like depth of service pipes below ground, the slope of the lawn, and distance of the slabs below the damp proof course (DPC) an amount of overall fall was calculated and then marked at the opposite end of the patio. In this case, a fall of 40mm over 6 meters was achieved which is a little under the desirable gradient of 1 in 80.
