IN-SITU CONCRETE SLAB ON GRADE WITH GRAVEL DRAINAGE CHANNEL 1:10 @ A2
9.3m2
Pour concrete (C20 mixture - 20N/m2) into formwork to depth of 100mm onto 100mm crushed gravel sub-base. Smooth with float trowel and finish with soft bristle brush to create small grooves (around 1mm deep) in the transverse direction to travel.

Padstones to support mesh. Spaced every 600mm.
Reinforcing steel rods.
Pour concrete (C20 mixture 20N/m2) thicker at edges over reinforcing steel rods to form a footing.
A142 reinforcing wire mesh to reduce cracking in concrete. Must always be a minimum of 50mm cover above around and below mesh.
Damp proof membrance (DPM), Visqueen or PIFA 1200. Where overlapping occurs ensure at least 350mm overlap and tap down.
