| Details for Retaining Wall Plans
 Free Retaining Wall plans - Before you build a retaining wall, first check if you need permission from your local council. If your wall is more than one metre high, call a professional. Otherwise, terrace a steep slope with two or more retaining walls. Water is the natural enemy of the retaining wall. Clay soils, or areas that collect water may require extensive draining. You can insert short lengths of pipes through the wall near the base. Another drainage method is to bury a perforated PVC pipe behind the wall. This pipe should extend beyond the end of the wall and slope 3mm every 300mm. Sandy soils may only require weep holes in the timber. Ask your local council for advice.
