How to build a children's sandpit
You can make a sand pit in any shape or size, but a simple 1m x 1m square gives children plenty of space for play.
Start by sawing eight sections of deck joist to form two square frames or 'boxes' that'll sit one on top of the other. For each box you'll need two lengths of exactly one metre and two of 1.056m to allow for the overlap at the corner joins. Drill pilot holes and fix the joists together at each corner using two 100mm galvanised nails.
Lay one box frame in position on the ground and mark the outer corners with canes. Then join the canes with builder's line or string to outline the hole. Next, dig a hole to the depth of the two stacked boxes. Put one box frame on top of the other and clamp them together, making sure they're flush and square. Then join them with a perforated metal plate in the middle of each side, secured with 25mm galvanised nails.
The exterior frame, made from deck boards, will rest on the ground - forming a seat around the top of the sand pit. To make it, take four 28mm x 144mm pieces of deck board. Secure each one in a workbench and cut one end to a 45 degrees angle.
To cut the other ends accurately, line the deck boards up around the box, one at a time. Align the angled end with one corner and mark the point where it touches the next corner. Use this as your starting point for cutting the other end. If the box is exact, the inside, shorter edges of the frame sections will be exactly one metre long.
On a flat surface, glue the joints with a strong waterproof wood adhesive. Then nail a perforated metal plate across the underside of each joint with 25mm nails. Wipe away any surplus glue with a damp cloth, and leave to dry.
Once everything is securely bonded, drill pilot holes and fix the seating to the top of the box with 75mm countersunk deck screws. Fill the holes with wood filler and sand them smooth.
Now you can paint the frame. When it's dry, attach a sheet of heavy-duty plastic or weed control fabric to the bottom of the box with evenly-spaced 10mm felt nails.
Scatter a thin layer of sand into the bottom of the hole and lower your finished box into it.
If you're using plastic liner, perforate it with a garden fork. Make plenty of holes to allow for drainage and prevent your sand pit from becoming soggy. Then fill it with play sand. It's good idea to cover it when it's not in use to stop it getting waterlogged.
