How to mark and dig good foundations

It is essential that the foundations for new walls and houses are the right size and in the correct position to take the load of the wall and prevent movement. Strong foundations will prevent cracks and structural problems and make sure your home is a refuge for generations to come.

Your tools:

• Spirit Level
• Builders Line
• Spade
• Hammer
• Square
• Compactor
• Brick Course Gauge
• Wooden Straight Edge
• Wheelbarrow
• Pick

 
Step 1

After marking out the walls of the house, put pegs in the ground 1 metre away from the house marking. Nail a piece of wood horizontally across the pegs. This will be used to mark the foundations.
