Level 2 Certificate
All Level 1 content:
- Stripping Out: Cope stones laid in line approximately 2 metres from wall. Cover stones and throughbands laid next tothem. Building stones and packing placed both sides of wall. Foundation stones laid on top of building stones. Clearspace, free of stones both sides of the wall.
- Preparing and Laying Foundations: Foundation dug out and levelled. Foundation stones reaching as far into centre of wall as possible. Extra-large stones should be in the foundations. Foundation well-packed with hearting stones.
- Building and Packing: Stones laid tight together with good contact between stones. Stones laid “end in” and “end out”.No running joints further than two rows of stones. Coursing of stones if applicable and a definite line for throughbands, appropriate to wall height (usually mid-height but note regional variations). Good use of hearting, thoroughly packedin, and not thrown in. Tight wall with no loose stone. A definite line at coverband or cope height. The bigger the stones,the further down the wall they should be placed.
- Placing of Throughbands: Laid at approximately one metre intervals. Check they are lying solidly on the wall. Shouldprotrude 50-80mm on either side of wall (but note regional variations).
- Straightness of Line & Batter: Wall should come in evenly. Absence of bulges or hollows in the wall. Correct useof frame or pins to set batter. Correct use of lines: taut, level, correct width. Covers run evenly.
- Copestones and Finish: Stones should sit solid on their own base rather than propped up on pinnings. Vertical, tighttogether, well keyed to give a level finish (some regions have copestones on the slant, other regions have variations which should be observed, eg turf underneath copes). Minimum pinning, which should be neat and blendinto wall.
Additional for Level 2 Certificate
- Cheekend: Stones well tied-back into wall. Good selection of corner stones, well tied back into body of the wall. Norunning joints in face or where tied into the wall. A good solid end cope stone. Work from cheekend back into the wall.
