The kennels are all lined with 1" foam and then 1/2" ply on top of that sandwiched.... also osma drain pipes set in concrete and into main drains.... concrete has a 3" run off from back to front of kennel.... I used the torch on felting much easier than the other gear...well for me anyway... and my pal millet done the blockwork for me...
Kennel area 6' x 4' and run area 8' x 6' on each pen.
ps got the mesh for nothing 8' x 4' sheet galv off a mate who was into shopfitting, used them in asda,tesco, etc...
